The Space Activities Commission decision gives the Japanese government authority to request funding for the programs in its budget for the next fiscal year, which begins in April.

The government space panel, which has oversight of the Japan Aerospace Exploration Agency, only gave the go-ahead for preliminary design work on Hayabusa 2, a mission projected to cost nearly $200 million.

The commission recommended proceeding with full development of the Epsilon rocket, a new Japanese launcher to send small satellites into orbit beginning in 2013.

The Hayabusa 2 mission would blast off as soon as 2014 and reach a carbon-rich asteroid in 2018 for a touch-and-go approach to collect samples. After spending a few months in the vicinity of the asteroid, the probe would return to Earth in 2020.

The spacecraft's mission would replicate the feat accomplished by Hayabusa, the mission that completed the first round-trip journey to an asteroid in June. During its seven-year journey to and from asteroid Itokawa, Hayabusa suffered major glitches in its sample collection device, propulsion system and reaction wheels.

But the probe released an entry capsule that landed in Australia, possibly with the first microscopic dust grains from the surface of an asteroid.

Hayabusa 2 would incorporate improvements to the faulty systems that plagued its predecessor, but the craft would rely on the same fundamental design to slash costs.

Junichiro Kawaguchi, Hayabusa's project manager, said a "good indication was shown by the government" in negotiations and hearings over the past few weeks.

"Precisely speaking, still we need some more time to make it actually appropriated. But most opinions say the mission shall be performed," Kawaguchi wrote in an e-mail to Spaceflight Now.

Kawaguchi is managing the Hayabusa 2 proposal team, but he will relinquish leadership once the mission enters full development.

Hayabusa 2 would target an asteroid named 1999 JU3, a C-type body with a diameter of about 1 kilometer, or 0.6 miles. Scientists say C-type asteroids are the unspoiled relics of the early solar system, which was dominated by small bodies as the planets coalesced.

Itokawa, the destination for Hayabusa, is a stony rubble pile asteroid that formed from separate objects fusing together over time.

Japan is moving forward with Hayabusa 2 after the Marco Polo mission, a joint asteroid probe with Europe, was not selected by an international panel of scientific advisors earlier this year.

The budget decisions for JAXA are being considered as an economic stimulus, according to Kawaguchi.

Согласно информации с форума http://www.unmannedspaceflight.com Хаябуса 2 будет нести на борту мини-ровер (возможно модификации Минервы?), модернизированный "sample collector" с использованием нескольких различных систем сбора образцов, в том числе с помощью "липучки", а также импактор со взрывчатым зарядом на борту:

(http://savepic.org/651840.jpg)

После первоначального изучения астероида и сбора образцов, Хаябуса выпустит импактор и спрячется за астероидом. После взрыва образуется кратер диаметром 4-5 м и глубиной до 1м.:

(http://savepic.org/646720.jpg)

Дальнейший забор образцов будет производится из кратера. Предполагается что подобным образом удастся получить образцы "девственно чистого", нетронутого материала. Сама цель, астероид 1999 JU3, относится к С-классу, т.е. более примитивным телам, реликтам времен формирования Солнечной Системы.

ЦитатаХаябуса 2 будет нести на борту мини-ровер (возможно модификации Минервы?),
Нет, это будет Mobile Asteroid Surface Scout (http://www.planetaryprobe.eu/IPPW7/proceedings/IPPW7%20Proceedings/Presentations/Session7B/pr456.pdf), разрабатываемый для почти отмененной миссии Marco Polo. Такой 10 кг чемоданчик с 2-3 научными приборами, возможно прыгающий.

Нету там взрывчатки. Там кумулятивный боеприпас, который они называют "Explosively formed projectile":

Но вообще схема миссии и объект изучения вызывает у меня смешанные чувства. Как установил "Спитцер", 1999 JU3, как и Уран, вращается почти на боку, что очень неудобно в плане съемки. На построение одной только карты уйдет год. Еще 4 года они берут на перелет туда (и это имея в распоряжении H-2A, чья грузоподъемность в разы превышает требуемую). И еще год на обратный путь. Да за это время там опять 3 раза все сломается, и опять придется тянуть "на одном крыле".
Выбрали б какой другой астероид, с меньшими транспортными издержками.

Вот это дико интересно - астероид С-типа (углеродный!) и достаточно крупным - 1 км в диаметре! Только сомневаюсь в определению диаметра - Итокава значительно меньше, а ярче, чем 1999 JU3. Хотя он - каменный и должен иметь альбедо побольше.

Не думаю. Допустим на астероиде сила тяжесте 1/90 от земной.
Значит, иммитируя такую тяжесть на Земле, аппарат должен в подвешенном состоянии ползти по стене, с наклоном в 89 градусов, т.е. практически вертикальной. Провести эксперимент не сложно.
Результат, я думаю, предсказуем.

С того, что астероиды постоянно бомбардируются метеоритами. Вот, гляньте ка:

Если внимательно посмотреть, то все малые тела буквально завалены камнями, даже крошка Итокава поперечником порядка 200 м. Снимков Фобоса в нужном разрешении я не нашёл, но если посмотрите на нижний снимок, можете увидеть явные следы оползней на внутреннем склоне кратера. Так что если уж на Итокаве гравитация достаточная, чтобы удерживать камни на поверхности, на километровом астероиде  её всяко хватит. Когда первая Хаябуса, кстати, брала образцы, то на завершающем этапе она как раз на астероид падала. О

Вот я и говорю, что гравитации даже маленьких, в сотни метров астероидов достаточно, чтобы на них что бы то ни было лежало. Гравитация + микронеровности = поверхность, пригодная для езды. Признаться, для меня это стало большим сюрпризом. Ибо я представлял себе астероид так же, как и все - большой камень. Возможно, есть и такие. Но пока не встретились. Наверное, такими могут быть только самые маленькие - первые десятки метров поперечником.

Возможно, для ответа на эти вопросы было бы полезно отправить опытную установку на МКС. Установка за счет своего вращения создавала бы притяжения аналогичные астероидным - внутри этой установки можно было бы испытывать микророверы - проверять их качество сцепления с грунтом астероидов самой разной структуры.
 Слишком будет высока цена технической ошибки, если микроровер окажется недееспособным на астероиде.

Вы обратили внимание, что любая важная техника, любая конструкция, любой узел после создания проходят натурные испытания? Это делают профессионалы, в том числе авиационной и космической техники. И они испытывают огромное удовлетворение, когда результаты испытаний совпадают с их теоретическими расчетами. Но бывают и расхождения в силу каких-нибудь неучтенных условий в теоретических расчетах - и тогда конструкцию приходится дорабатывать.

ЦитатаЯпония увеличивает финансирование проекта космического аппарата Хаябуса-2[/size]

(04:20) 24.12.2010

Власти Японии решили выделить на создание космического зонда "Хаябуса-2" 3 млрд иен или более 36 млн долларов в рамках бюджета на 2011 финансовый год. Эта сумма, сообщили сегодня токийские СМИ, в сто раз превышает расходы на реализацию этого проекта в текущем финансовом году.

Столь резкое увеличение ассигнований на разработку нового межпланетного аппарата связано с амбициозными планами Японии развить успех его предшественника "Хаябуса-1", который был запущен в 2003 году. При посадках на астероид "Итокава" он не сумел провести полноценный сбор породы, как было запланировано, но в его капсулу все же попали мельчайшие образцы. После этого на Хаябусе вышла из строя связь, на время отказал двигатель. Однако зонд сумел восстановить функции и в июне этого года после самого длинного путешествия в истории освоения космоса вернулся и сбросил в австралийскую пустыню Вумера капсулу с образцами.

Возвращение зонда общей длиной вместе с раскрытыми солнечными панелями 5 м состоялось на три года позже намечавшегося срока. Расходы на его создание превысили 12,7 млрд иен или более 130 млн долларов. Создателям нового аппарата предстоит усовершенствовать конструкцию "Хаябуса-1", чтобы более успешно решить задачу доставки частиц грунта с поверхности далекого астероида.

Согласно планам Японского аэрокосмического агентства Jaxa, экспедиция "Хаябуса-2", общие расходы на разработку которого составят 14,8 млрд иен (178 млн долларов), начнется в 2014 году. Посадка на астероид 1999JU3 намечена на 2018 год, возвращение на Землю планируется на 2020 год, сообщает ИТАР-ТАСС

ЦитатаThere is an interesting feature on JAXA Japanese web site. What follows is its translation.



We are currently considering a new device for Hayabusa 2 which was not carried by Hayabusa. It is a collision device. It will be seperated from Hayabusa 2 above 1993 JU3 and when the mothersdhip hides behind the asreroid it will explode in mid air. Then, approx. 2kg collision mass will collide with the asteroid surface and create a crater of approx. a few meters insize.

After that, collection and sampling of the newly disclosed surface will be attempted. (end of translation)

I would have thought that crater making can be best and least problematically achieved by an explosive device, somehow gently placed on the asteroid surface. That would have been space mining, but this is just a collision process!

Hayabusa2 revealed before the first integration test

On Dec. 26, the Hayabusa2 was revealed at the Sagamihara Campus. As its design was completed this spring, the Hayabusa2 will soon undergo the first integration test to confirm the interfaces among onboard devices as well as between the devices and the explorer's bus after assembling them onto the bus. Also, the flight models of the Hayabusa2's main body and solar array paddles have already been manufactured, thus those models will be verified through a vibration test. In addition, the exposed environment for the onboard devices will also be measured. JAXA is developing the Hayabusa2 to be ready for its launch in 2014.

В Японии продемонстрирован космический аппарат "Хаябуса-2"

// CyberSecurity.ru // - Японское космическое агентство сегодня показало журналистам законченный вариант нового космического аппарата "Хаябуса-2", который планируется запустить в космос в декабре 2014 года для полета на астероид и доставки материалов с него. В космическом агентстве говорят, что новая миссия продолжит исследования, сделанные аппаратом "Хаябуса" в 2010 году, который благополучно доставил на Землю частички с астероида Итокава.
 
 Японское агентство на протяжении следующих 12 месяцев проведет серию экспериментов, чтобы выяснить, смогут ли ученые решить проблемы, которые выявил запуск предыдущего космического аппарата.
 
 Аппарат "Хаябуса-2" должен будет к середине 2018 года сблизиться с астероидом 1999 JU3 и взять с него образцы вещества. Доставить их обратно на Землю планируется в 2020 году. Согласно сегодняшним данным, астероид 1999 JU3 имеет в диаметре 914 метров - немного больше, чем Итокава, а кроме того он почти правильно сферический, тогда как Итокава был вытянутый.
 
 Как и другие космические агентства, японское Jaxa работает в условиях нехватки финансирования и жесткого временного лимита, поэтому здесь не исключают вероятности того, что Хаябуса-2 будет запущен во второе стартовое окно - в 2015 году, впрочем, пока японцы в график укладываются. Если же запустить Хаябуса-2 не получится ни в 2014, ни в 2015 годах, то ждать придется уже до 2024 года, когда астероид опять подойдет на приемлемое расстояние.
 
 Хаябуса-2 должен будет приблизиться к астероиду 1999 JU3 и найти там органические молекулы, аналогичные тем, что миллиарды лет назад могли быть занесены на Землю и стали фундаментом, на базе которого развивалась жизнь.
 
 Японские специалисты отмечают, что при разработке Хаябуса-2 они учтут опыт проблем, возникших с Хаябуса-1. На второй версии аппарата также будет присутствовать 30-сантиметровая капсула Импактор, которой предстоит совершить небольшой взрыв на поверхности астероида и взять пробы внутреннего материала. В определенном смысле миссия Хаябуса-2 будет легче, чем Хаябуса-1, так как второму аппарату придется опускать капсулу на километровый астероид, а вот площадь Итокава составляла всего около 500 метров.
 
 В Jaxa рассказывают, что в результате взрыва будет создана метровая воронка, на дне которой будет внутренний материал астероида, который не так сильно подвергся воздействию губительной солнечной радиации. В случае с Хаябуса-1 взрыва не было и Импактор буквально соскребал материалы с поверхности астероида. В случае с Хаябуса-2 у аппарата будет целых два варианта для сбора астероидного материала: первый предусматривает выброс своеобразного пылесборника, второй - выброс липкой субстанции, которая пройдет по стенкам воронки и соберет нужные науке материалы. Обе системы будут присутствовать на аппарате и обе они будут нужны для повышения вероятности получения нужных проб.
 
 Инженеры рассказывают, что аппарат также получит новый двигатель, с более высокой системой отказоустойчивости, обновленную систему контроля в пространстве и улучшенные системы связи с нашей планетой.
 
 "Пыль, собранная Хаябуса-2 , вероятно, сможет нам что-либо поведать о происхождении жизни на Земле. Одна из теорий возникновения жизни на Земле гласит, что первые сложные аминокислоты на планету были доставлены из космоса, когда один из астероидов врезался в Землю миллиарды лет назад", - говорят в Jaxa.

Зонд "Хаябуса-2" возьмет с собой на астероид послания всех желающих

МОСКВА, 2 апр -- РИА Новости. Японское аэрокосмическое агентство JAXA предлагает всем желающим записать их имена, послания и фотографии на электронный чип, который в 2014 году отправится в путешествие к астероиду вместе с зондом "Хаябуса-2".
В сообщении агентства отмечается, что цель кампании -- популяризировать в обществе японскую программу по исследованию космоса.
Запуск зонда "Хаябуса-2" запланирован на 2014 год (http://ria.ru/science/20120127/550415224.html), в 2018 году аппарат должен прибыть к 920-метровому астероиду 1999 JU3, высадить на него германский "прыгающий" посадочный модуль MASCOT, взять пробы грунта и в 2020 году вернуться на Землю. При этом в спускаемой капсуле и в специальной метке, которая останется на поверхности астероида, будут находиться микрочипы, на которые будут записаны имена, иллюстрации и послания от всех желающих по всему миру.
Пыль с "Хаябусы" рассказала о смерти и перерождении астероида Итокава>> (http://ria.ru/science/20110825/424068400.html)
После 10 апреля, когда начнется прием заявок, любой человек или организация сможет отправить в агентство свое имя (не более 20 знаков с пробелами) для того, чтобы записать их либо на тот чип, который останется на астероиде, либо на тот, что совершит путешествие "туда и обратно". Порядок отправки посланий и графики агентство обещает уточнить в ближайшее время. В сообщении подчеркивается, что послания и иллюстрации могут быть опубликованы на сайте агентства.
"Имейте в виду, что микросхемы памяти будут подвергаться воздействию факторов космического пространства, включая космическую радиацию, в течение долгого времени, поэтому записанные данные могут быть повреждены", -- отмечается в сообщении.
Предшественник аппарата зонд "Хаябуса" был запущен в космос в мае 2003 года (http://ria.ru/science/20100114/204430568.html). Это единственный космический аппарат, совершивший посадку и взлет с поверхности космического тела за пределами системы Земля-Луна. В 2005 году он совершил посадку на астероид Итокава, однако из-за неполадок взятие проб грунта прошло не по плану. В капсуле зонда, приземлившегося в середине июня 2010 года (http://ria.ru/science/20100614/246098628.html) в австралийской пустыне Вумера, были обнаружены микроскопические частицы, состав которых во многом похож на состав метеоритов, что доказывает их внеземное происхождение (http://ria.ru/science/20101116/296863850.html). По мнению ученых, скорее всего, они являются частью поверхности астероида Итокава.

ЦитатаJapan nears launch of probe to retrieve asteroid samples
BY STEPHEN CLARK
SPACEFLIGHT NOW
Posted: September 1, 2014

The Hayabusa 2 asteroid probe, on track for liftoff this winter, will be shipped to its island launch base at the end of September for final preparations to start the most audacious space exploration mission ever attempted by Japan.
 (http://www.spaceflightnow.com/news/n1409/01hayabusa2/01hayabusa2_400265.jpg)

 The mission will take off on top of an H-2A launcher as soon as December, fly to an asteroid scientists believe is a relic from the genesis of the solar system, drop a European-built lander, and return to Earth in 2020 with extraterrestrial rock samples.
The Japan Aerospace Exploration Agency revealed Hayabusa 2 to media Sunday as it neared the finish line in a four-year effort to design, construct and test the spacecraft.
Japanese officials have not announced the target launch date, but they say the mission is on schedule to lift off as soon as December in a narrow window when Earth and Hayabusa 2's target asteroid are properly positioned to make the journey possible.
Backup launch windows are available in June and December 2015.
The spacecraft, now almost fully assembled for flight, will soon wrap up testing at JAXA's Sagamihara campus near Tokyo, according to Hitoshi Kuninaka, Hayabusa 2's project manager.
"At the end of September, the spacecraft will be transported to Tanegashima," Kuninaka said.
Hayabusa 2's launch is next in line for liftoff from the Tanegashima Space Center -- located on Tanegashima Island in southwestern Japan -- after an Oct. 7 launch of the Himawari 8 weather satellite.
Once the spacecraft arrives at the launch site, Kuninaka said technicians will install pyrotechnic charges for its mission, which include explosives to excavate material from beneath the asteroid's surface. Ground crews will also add the mission's flight batteries and fill the probe with xenon gas and hydrazine propellant.
JAXA says the Hayabusa 2 mission's cost is 28.9 billion yen, or about $275 million.
Hayabusa 2's launch follows four years after its namesake -- the hard-luck Hayabusa mission -- returned to Earth with microscopic specimens collected from asteroid Itokawa.
Engineers designed Hayabusa with upgrades to expand its scientific payoff and increase its chance for success.
Hayabusa 2 carries four xenon-fueled ion thrusters for the voyage to asteroid 1999 JU3, an object with a diameter of about 3,200 feet that researchers believe is made of primitive rock left over from the ancient solar system.

 After a swingby of Earth in late 2015 to get a gravity boost, the 1,320-pound craft will arrive at 1999 JU3 in June 2018 and loiter around the asteroid for about 18 months.
Once it arrives at asteroid 1999 JU3, Hayabusa 2 will survey the rock with an array of instruments, including imagers, a spectrometer, and a terrain-mapping altimeter.
The craft will also release a small Japanese rover named MINERVA to hop across the surface of the asteroid and deploy the MASCOT lander developed by the German Aerospace Center, or DLR.
Hayabusa spent about three months exploring Itokawa, an asteroid about half the size of 1999 JU3.
Hayabusa 2's destination is a different type of miniature world than Itokawa. Asteroid 1999 JU3 is a C-type asteroid, a classification of primitive objects made of organic and hydrated minerals.
Itokawa is an S-type asteroid composed of rocks and metals heated and modified over the solar system's 4.5 billion year history, causing the material to lose chemical markers left over from the dawn of the solar system.
Scientists expect the Hayabusa 2 samples to hold a record of the tumultuous early phases of the solar system's formation, including the basic building blocks of life such as amino acids.
Hayabusa 2 will collect up to three samples from 1999 JU3, including material blasted from beneath the asteroid's surface by a explosive grapefruit-sized copper impactor released from the mothership.
Depending on the texture of the rocks on 1999 JU3, Hayabusa 2 should pick up between a gram and several grams of samples.
After up to three close approaches to acquire samples, Hayabusa 2 will depart the asteroid in December 2019 and deploy a sample-bearing re-entry capsule into Earth's atmosphere in December 2020.

Немножко по-русски:

"В конце 2014 года Япония собирается отправить к астероиду 1999 JU3 спускаемый зонд Hayabusa-2. Путешествие займет четыре года: к 2018 аппарат достигнет космического тела, сообщает Agence France-Presse (http://www.afp.com/).
Предполагается, что Hayabusa-2 прикрепится к космическому объекту и возьмет образцы грунта, которые к 2020 году будут доставлены в Японию. Возвращение зонда планируют приурочить к XXXII летним Олимпийским играм, которые пройдут в Токио.
Как заметил на пресс-конференции руководитель Японского агентства аэрокосмических исследований Хитоси Кунинака (Hitoshi Kuninaka), специалисты возглавляемой им организации собираются удвоить свои усилия, чтобы запуск и возвращение космического аппарата прошли в рамках заданного графика. По его словам, работы по сборке Hayabusa-2 почти завершены.
Новый зонд является преемником первого Hayabusa, который взял образцы грунта с околоземного астероида Итокава. Японская ракета-носитель Mu-5 с зондом стартовала 9 мая 2003 года с площадки космического центра Утиноура. Миссию планировалось завершить в июне 2007 года, однако из-за неполадок с солнечными батареями, возникших вследствие солнечных вспышек, и двигателями капсула с грунтом прибыла на Землю только 13 июня 2010 года.

Форма и относительная доступность астероида Итокава послужили основными причинами для его выбора в качестве цели для первой миссии. Диаметр космического тела равен 0,33 километра, а масса составляет 35 миллионов тонн.
Астероид 1999 JU3 также относится к группе околоземных. Объект имеет диаметр менее километра. Период обращения тела вокруг Солнца равен 474 суткам, а средняя орбитальная скорость -- 27 километрам в секунду.
Hayabusa-2, в отличие от предшественника, в состоянии собрать твердые образцы грунта, а не только астероидную пыль. Официально заявленной целью миссии Hayabusa-2 является изучение космического материала, которое бы пролило свет на эволюцию ранней Солнечной системы более 4,5 миллиардов лет назад."

И вот ИТАР-ТАСС об этом сообщает:

"Правительство Японии приняло решение 30 ноября запустить уникальный космический зонд "Хаябуса-2" ("Сокол-2") к одному из астероидов для сбора пробы грунта. Об этом объявил на пресс- конференции министр образования, спорта, науки и технологий Хакубун Симомура.
Аппарат будет запущен тяжелой ракетой Эйч-2А, которая стартует с единственного в Японии космодрома на острове Танэгасима. "Хаябуса-2" в 2018 году должен приблизиться к астероиду 1999JU3, чтобы взять там образцы почвы. По мнению ряда ученых, в ней могут содержаться органические вещества и вода. Этот эксперимент, как полагают исследователи, способен пролить свет на пути распространения жизни во Вселенной."

"...По мнению ряда ученых, в ней могут содержаться органические вещества и вода..."
Интересно, и с чего бы это на астероиде такая роскошь?
Или это просто из серии "могут быть, а могут и не быть, причём оба варианта равновероятны"?

Вот-вот... В комете Вильда Стардаст глицин добыл, почему ему не быть на астероиде? Вот только я про соотношение изомеров ничего не нашёл. Либо плохо искал, либо его там слишком мало было, чтобы померить.

Это называется: "спасибо за вопрос!"

Почитал про астероиды, понял, что по данным спектрального анализа и вода, и органические вещества там должны быть, по крайней мере, на астероидах класса С.
Хотя всё равно, убей - не понимаю, почему первая не испаряется (видимо, как-то связана), а вторые - как попали или как синтезируются в условиях астероида, но с астрономами не поспоришь.

Но у меня ещё одно сомнение - можно ли взять на астероиде 1999 JU3 "образцы ПОЧВЫ"? :-)

Можно, это калька с английского soil, означающего и грунт, и почву, и по мере надобности - даже реголит. Т.е. с точки зрения обывателя и почвоведа звучит диковато, но на взгляд человека, непритязательного к творчеству журналистов - вполне допустимо.

А можно поинтересоваться, какого рода изомеры вы искали?
Нитроэтан? Метилкарбамат; метилуретан; уретилан? Этилнитрит? Ацетогидроксамовую кислоту?

Блин, что я несу. Я, конечно, имел в виду оптические изомеры, которых у глицина нет  :)  Это доказывает, что ночью надо спать, а не читать ФНК  :)
Вот если бы там нашли что-нибудь посложнее, например, аланин, то была бы интрига с соотношением оптических изомеров.

Ну как синтезируются  - химия высоких энергий может предложить кучу гипотетических схем. Там под действием ионизирующих излучений высоких энергий все время образуется ювенильная поверхность со сверхвысокой концентрацией активных центров любой природы. Голубая мечта любого спеца по гетерогенному органическому катализу.  ;)

По некоторым возрениям вся галактическая органика именно в подобных условиях активных кластеров и образуется.

Если так - там должен быть подлинный рай для химиков и биохимиков.
За миллионы лет экспозиции можно предположить, что там образовалась огромная палитра соединений на основе углерода (да и не только - может, и кремния, если он там есть) от общеизвестных до любых "химер", возникающих в условиях бомбардировки частицами самых различных энергий...
Успеха "Хаябусе-2"!

Не стоит забывать, что наличие мощных потоков высоэнергетических ИИ обеспечивает и множество путей обратных реакций радиолиза(разложения) органики. То, что там в наличии - результат динамического равновесия между прямыми и " обратными" реакциями. Иначе говоря экзотика - она коротко живущая :!:  Нужны специальные, очень сложные флешь-методы для ее диагностики. Они вряд ли доступны для Хаябусы, и они не столь интересны для космохимиков и астрономов.

Япония запустила космический зонд «Хаябуса-2» к астероиду 1999JU3 с помощью ракеты-носителя Н-2А с космодрома Танэгасима на юге страны, передает РИА Новости (http://www.ria.ru/). Японское аэрокосмическое агентство (JAXA) транслировало запуск в прямом эфире.
«Хаябуса-2» представляет собой аппарат с размерами 1,5 на 1 на 1,6 метра, весом 600 килограмм. Он должен будет помочь разгадать тайны возникновения и развития Солнечной системы и зарождения жизни.
«Хаябуса-2» приземлится на астероид в 2018 году и пробудет там полтора года. В конце 2019 года он отправится в обратный путь и вернется на Землю в 2020 году. Астероид удален от Земли на 300 миллионов километров, но из-за сложности попадания аппарата на столь малое (900 метров) космическое тело, зонду за шесть лет придется проделать путь в 5,2 миллиарда километров.

Разве траектория полёта зависит от размеров тел, между которыми необходимо сделать перелёт (Земля - астероид)?
А, случайно, - не от взаимного расположения траекторий вращения тел вокруг Солнца и координат тел на этих траекториях в момент старта?

Japan Aerospace Exploration Agency (JAXA)
The Japan Aerospace Exploration Agency (JAXA) confirmed the completion of a sequence of the important operations for the Asteroid Exploration "Hayabusa2" mission including the deployment of the horn part of the sampler that captures samples from the asteroid's surface, the release of the locks for the launch that ratchet the gimbal that controls the direction of the ion engine, and functional verification of the three-axis stabilization controls and the ground precision orbit determination system. With this confirmation, the critical operation phase* of the Hayabusa2 was completed.

The sampler horn deployment was confirmed by images taken by the onboard small monitor camera that was manufactured and loaded onto the Hayabusa2 thanks to donations for the Hayabusa2 mission from many of you. We would like to express our deepest gratitude to all of you again.

 (https://testforum.novosti-kosmonavtiki.ru/forum/file/50844)

The explorer is now in a stable condition.

The explorer will move to the initial functional verification operation phase to verify the function of the satellite onboard instruments for about three months.

Hayabusa2 in great shape - Initial functional confirmation going smoothly
http://global.jaxa.jp/projects/sat/hayabusa2/topics.html#topics3767

ЦитатаThe Hayabusa2, launched on Dec. 3, 2014 (JST), is now undergoing the initial functional confirmation. Basic operations and performance of onboard instruments and ground systems have been tested one by one as of the end of January.

Here are some major examples of what we confirmed.
  • Ion engine test operation (one unit at a time)
    Four ion engines were being operated one by one. A thrust of 7-10 mN was generated on the orbit for the first time.
  • Establishing communication by Ka band communication equipment (Between Jan. 5 to 10, 2015)
    Communication was successful between the Hayabusa2 and NASA DSN stations to establish deep-space Ka-band communication for the first time for a Japanese space explorer. Ka-band communication will be used to send observation data during the mission for the Hayabusa2 to stay near the asteroid.
  • Ion engine can autonomously operate for 24 hours.
    Long duration of autonomous operation with two or three ion engines was tested, and 24-hour continuous operation was attained.
    The maximum thrust was confirmed to be about 28 mN, which is the expected value.
The explorer is currently in good shape.
We will further confirm the coordinated function of multiple instruments of the Hayabusa2, and plan to move to the cruise operation phase sometime in March.

 Ultra-small spacecraft of development such as approaching observation abandoned = Tokyo University of asteroid

Was launched along with the asteroid probe "Hayabusa 2" in December last year, had been aiming to close observation to another asteroid ultra-small spacecraft for "Procyon", University of Tokyo and the Japan Aerospace Exploration Agency is the 8th, for navigation failure of the ion engine is not recovery, it was announced that it would abandon the approach observation to the asteroid that was the goal.
Procyon is 50 kg class of ultra-small spacecraft Tokyo University and the Space Agency has been developed. For toward the asteroid goal, but had planned the acceleration (swing by) using the Earth's gravity in December this year, the operation of the ion engine has stopped in March.
The development team tried to remove it seen that there is a high possibility that it is shorted to adhere the dust fine metal electrode for accelerating the ions, the thrust is not sufficiently recovered, it became impossible to swing-by.
Future, and that continue to discuss how the operation for the continuation of the observations and functional demonstrations using the onboard equipment. (2015/05 / 08-15: 12)

http://global.jaxa.jp/news/2015/#news5842
http://www.jaxa.jp/press/2015/10/20151005_ryugu_j.html


"Ryugu" was selеcted as name of Hayabusa2 target asteroid

ЦитатаAsteroid 1999 JU3, a target of the Asteroid Explorer "Hayabusa2," was named "Ryugu".

One major reason for the selection was that, in the Japanese ancient story "Urashima Taro", the main character, Taro Urashima, brought back a casket from the Dragon's palace, or the "Ryugu" Castle, at the bottom of the ocean, and the theme of "bringing back a treasure" is common as the Hayabusa2 will also bring back a capsule with samples. It was selected among 7,336 entries.

Thank you very much to so many of you who took part in the naming campaign.

Хаябуса-2 готовится к пролету Земли.

3 ноября в 15:00 JST аппарат провел коррекцию траектории TCM1, обеспечившую необходимые условия для проведения гравитационного маневра у Земли. Сам пролет планируется на 3 декабря 2015 года, минимальное расстояние до поверхности составит 3100 км и будет достигнуто в 19:07 JST (10:07 UTC или 13:07 МСК) над Тихим океаном западнее Гавайев. Подробную анимацию пролета можно посмотреть здесь (https://www.youtube.com/watch?v=Kjqff5bkUrE), а здесь (http://www.lizard-tail.com/isana/hayabusa2/misc/swingby/) показывается положение аппарата в реальном времени. Еще одна полезная симуляция Хаябусы-2, планет и астероида Рюгю находится тут (http://www.lizard-tail.com/isana/hayabusa2/).

Пролет АМС попытается отследить (http://www.city.himeji.lg.jp/hoshinoko/kansoku/openobs/hayabusa2_obs.html) кооперация JAPOS (Japan Public Observatory Association), состоящая как из профессиональных астрономов, так и любителей. Ожидается, что аппарат с размахом СБ около 6 метров будет иметь яркость 11-12m, хотя увидеть его в вечернем небе Японии до захода в тень будет непросто. Куда более выигрышные условия складываются для наблюдателей Сибири и Дальнего Востока, где Хаябуса-2 пройдет практически в зените.

После пролета Земли аппарат еще какое-то время будет двигаться по баллистической траектории, а потом приступит к разгону на ионных двигателях. Для достижения астероида планируется 3 активных участка: апрель-июль 2016-го, январь-июнь 2017-го и с декабря 2017-го до прибытия к Рюгю летом 2018 года. Приращения скорости на каждом из них, а также расстояния КА до Земли и Солнца приведены на рисунке выше.

Попутчик Хаябусы-2, микроАМС PROCYON сейчас также приближается к Земле. Несмотря на отказ ионного двигателя и невозможность совершить гравитационный маневр, аппарат все-таки пройдет не очень далеко от планеты  - примерно в 2.7 млн км, также 3 декабря 2015 года. С начала ноября камера PROCYON ведет регулярную съемку Земли и получает довольно приличные для такого оборудования и таких обстоятельств кадры.

Дальнейшая программа миссии пока не озвучивалась. Не имея возможности совершить пролет астероида 2000 DP107 в январе 2016-го, PROCYON продолжит дрейф по гелиоцентрической орбите, близкой к орбите Земли; в следующие месяцы расстояние до него не превысит 0.3 а.е. Если рядом попадется что-то интересное, аппарат cможет провести наблюдения, как он это делал (https://www.rikkyo.ac.jp/news/2015/10/16852/) недавно с кометой Чурюмова-Герасименко.

The Japan Aerospace Exploration Agency (JAXA) performed an Earth swing-by operation of the Asteroid Explorer "Hayabusa2 " on the night of December 3 (Thu.), 2015 (Japan Standard Time). The Hayabusa2 flew closest to the Earth at 7:08 p.m. (JST) and passed over Hawaii at an altitude of about 3,090 km.

The Hayabusa2 project team is currently measuring and calculating the post-swing-by orbit. It will take about a week to confirm if the explorer entered the target orbit. We will report the result once it is determined.

The Hayabusa2 is in good health.

"Хаябуса-2" успешно перешла на орбиту для сближения с астероидом
Москва. 14 декабря. INTERFAX.RU - Космический аппарат "Хаябуса-2" успешно выполнил околоземный маневр по ускорению и перешел на новую орбиту для сближения с астероидом Рюгу, сообщает сайт N+1 со ссылкой на Японское Агентство Аэрокосмических исследований JAXA.

В июне-июле 2018 года ожидается, что зонд достигнет астероида, возьмет пробы его поверхности и доставит их на Землю, как это сделал его предшественник - "Хаябуса-1".

Аппарат воспользовался гравитационной пращей (маневр для ускорения объекта под действием гравитационных полей небесных тел - ИФ) Земли для того, чтобы увеличить свою скорость и значительно скорректировать настоящую орбиту. В результате прирост его скорости составил 1,6 километров в секунду - теперь зонд движется со скоростью 31,9 километров в секунду относительно Солнца. Орбита "Хаябусы-2" повернулась примерно на 80 градусов.

Маневр произошел 3 декабря 2015 года. Максимальное сближение с Землей составило 3 090 км - в этот момент аппарат пролетел над Тихим океаном, вблизи Гавайских островов. В следующие два года космический аппарат, двигаясь по спирали, достигнет Рюгу - небольшого околоземного астероида.

"Хаябуса-2" был запущен 3 декабря 2014 года с космодрома в Танэгасиме. Сейчас он удаляется от Земли и находится более чем в четырех миллионах километров. Возврат аппаратом образцов грунта Рюгу ожидается в декабре 2020 года.

Хаябуса-2 : полет нормальный.

Согласно недавнему докладу (http://www.lpi.usra.edu/sbag/meetings/jun2016/presentations/Tsuda.pdf) на конференции SBAG аппарат находится в хорошем состоянии и потихоньку продвигается к цели. С 22 марта по 20 мая 2016 г. Хаябуса выполнила первый этап разгона на ионниках. Суммарное время работы двигателей составило 798.6 часов, приращение скорости - 127.7 м/с. В начале июня аппарат, который в тот момент находился между Землей и Марсом, наблюдал Красную планету с помощью телескопической навигационной камеры ONC-T.

Почему мало то?
При массе аппарата в 500 кг это подразумевает тягу 23.6 мН, тогда как номинальная тяга (http://erps.spacegrant.org/uploads/images/2015Presentations/IEPC-2015-333_ISTS-2015-b-333.pdf) одного двигателя "Хаябусы" 6.3-9 мН. Вот он на 3 двигателях на полной тяге и шел.

ЦитатаЯпонский зонд впервые сфотографировал астероид Рюгу между Землей и Марсом
ТОКИО, 1 марта. /ТАСС/. Японский космический зонд Hayabusa-2 ("Сокол-2" ) сумел впервые сфотографировать конечный пункт своего полета, астероид Рюгу. Аппарат успешно отослал снимки на Землю за 300 млн км, сообщил в четверг телеканал NHK (https://www3.nhk.or.jp/news/) со ссылкой на национальное аэрокосмическое агентство (JAXA).
Астероид Рюгу диаметром всего 900 метров находится между Землей и Марсом. Аппарат Hayabusa-2 запустили к нему в декабре 2014 года с космодрома на острове Танэгасима. Сейчас зонд приближается к астероиду со скоростью 350 м/с (1260 км/ч).
Аппарат находится на расстоянии 1 млн км от цели путешествия. Ожидается, что он прибудет к астероиду летом этого года. После этого зонд должен совершить посадку на Рюгу, взять образцы пород и вернуться на Землю. Ученые надеются найти на астероиде следы органических веществ, что может помочь в разгадке тайны распространения жизни во Вселенной.
Hayabusa-2 весит около 600 кг. Он представляет собой модифицированную версию первого "Сокола", который впервые в истории науки сумел доставить на Землю материалы, собранные на поверхности иного, нежели Луна, космического объекта. В мае 2003 года он отправился к удаленному от Земли на 336,5 млн км астероиду Итокава. За семь лет зонд проделал самое длинное в истории человечества путешествие длиной 6 млрд км.
По первому Соколу - нужна оговорка: "с возвращением на Землю". Иначе - Вояджеры!

Artist's Impression of Hayabusa 2 Approaching Ryugu - Image: Akihiro Ikeshita

Japan's Hayabusa 2 spacecraft - on a quest to touch an asteroid - has set its sight on its destination in late February via the first detection of asteroid Ryugu by the craft's Telescopic Optical Navigation Camera that will be used to guide it into close proximity to the distant world later this year.

The probe still has over a million Kilometers to cover in order to reach its target in June for a one-and-a-half-year exploration mission that will see the spacecraft dispatch a series of landers and an impactor while also making contact with Ryugu itself to scoop up sample material to be returned to Earth in December 2020.

The first optical images of Ryugu, only appearing as a speck of light, were taken by the faraway spacecraft on February 26, Day 1,181 of the Hayabusa 2 mission that started back on December 3, 2014 with a successful launch atop an H-IIA rocket that sent the 590-Kilogram craft on a three-and-a-half-year journey to Ryugu - a 920-meter C-type primitive body that is hoped to hold a treasure trove of scientific information in the form of a preserved record of the early days of the solar system.

Sent off at a top speed of 11.8 Kilometers per second (relative to Earth), Hayabusa 2 entered a heliocentric orbit and completed 547 hours of ion engine firings between March and September 2015 to adjust course for an Earth flyby on December 3rd that saw the spacecraft zip past the planet at an altitude of around 3,090 Kilometers and borrow some of Earth's angular momentum to speed up in its orbit around the sun to reach asteroid Ryugu. The speedy flyby provided a welcome opportunity for exercising the craft's instrument suite and collecting calibration data of a very well-known target.

Heading back out, Hayabusa 2 was set for two major orbit-adjustment campaigns using its ion engines to slowly catch up with Ryugu that orbits the sun at 0.96 by 1.42 astronomical units. Some testing of the craft's critical systems including the long-distance Ka-Band communications link were carried out along the way and the ion engines were operated for 794 hours between March and May 2016 to adjust the craft's solar orbit by changing its speed by 127 m/s and adding a brief fine-tuning maneuver of 40 cm/s. The second orbit-adjustment campaign between November 2016 and May 2017 operated three of the four engines for 2,558 hours to change the craft's speed by 435 m/s.

Hayabusa Orbit Evolution - Image: JAXA

Hayabusa began firing three of its four ion engines again on January 10, 2018 marking the initiation of the far-field approach phase to take the spacecraft toward its destination with ion engine operation planned to last until early June when the final approach phase will be initiated fr om a distance of 2,500 Kilometers. Until June, the ion engines are expected to operate for 2,700 hours for a total delta-v of around 400 meters per second.

On February 26, Hayabusa pointed its Telescopic Optical Navigation Camera ONC-T toward Ryugu's location and snapped approximately 300 images, a subset of which were transmitted on the 27th and indeed show the asteroid at an optical magnitude of 9. At the time the images were taken, the spacecraft was still 1.3 million Kilometers from its destination.

The ONC-T images provided independent confirmation that Hayabusa 2 is on the correct approach course toward Ryugu in addition to constant radio tracking of the spacecraft's trajectory. According to Project Management, the spacecraft remains in excellent health and the current ion propulsion phase will proceed with maximum thrust.

Reaching the approach point in early June, Hayabusa 2 will rely on its three Optical Navigation Cameras to provide relative navigation data used by mission teams on Earth to plan the spacecraft's final approach, first into a 20-Kilometer surveying orbit wh ere the spacecraft is expected to arrive by July 5th. It will then be set for a step-wise descent first to five and then to one Kilometer from Ryugu's surface to collect detailed remote-sensing data of the asteroid using a pair of infrared spectrometers tasked with studying the energy balance of the asteroid as well as its chemical composition.

The primary payload of Hayabusa 2 is a sample collection system that will acquire small amounts of surface samples during as many as three brief touchdowns of the main spacecraft on the asteroid's surface using a high-fidelity navigation system that allows the spacecraft to make contact with the surface just long enough to shoot down a projectile and scoop up lifted dust through a sampling horn.

Furthermore, the spacecraft will dispatch four landers - the 10-Kilogram MASCOT lander built in Europe for an in-situ study of surface composition and properties, and three MINERVA landers to deliver imagery and temperature measurements. All landers will make several hops across the asteroid's surface to take measurements at different locations.

Another payload of the mission is an impactor device that will be deployed towards the asteroid and use high-explosives to generate a high-speed impact that is hoped to expose material from under the asteroid's surface for later collection by Hayabusa 2. A deployable camera will be used to document the impact of the penetrator.

The number of touch-and-go attempts and landers to be dispatched not only makes Hayabusa 2 one of the most complex missions currently in operation but also creates a packed schedule for the 18 months it plans to spend in proximity to the asteroid. Per current planning schedules, the initial touchdown and lander deployment is planned for September/October followed by a brief intermission ahead of touchdown #2 in February 2019, the release of the impactor in March/April and the third touchdown one month later. Departure of Ryugu is expected in December 2019 for a one-year return journey expected to culminate with the high-speed re-entry and landing of the hermetically sealed Sample Return Capsule in Australia.

ЦитатаHayabusa2's Star Tracker has successfully imaged Ryugu!
(http://www.hayabusa2.jaxa.jp/img/mainv_hayabusa2.png)
Hayabusa2 is currently operating its ion engines as the spacecraft approaches asteroid Ryugu. But on May 11, the ion engines were temporarily stopped so that the onboard Star Tracker (see note 1) could take a photograph of Ryugu. This observation of the direction of Ryugu from the spacecraft will be used for optical navigation (see note 2).
The Star Tracker took three sets of three images approximately one day apart, between May 11 - 14. The three images in each set were separated by several hours. The images were all taken successfully and were used to accurately measure the position of Ryugu in each image. We have now begun to use this data to determine the accurate orbits of both spacecraft and asteroid.
(http://www.hayabusa2.jaxa.jp/topics/20180515_e2/img/Fig1e.jpg)  Figure 1: Photograph of Ryugu using the Star Tracker. The celestial body within the yellow circle is Ryugu, moving from right to left across the image. The photographs were taken at approximately 01:00 on May 12, 02:00 on May 13 and 01:00 on May 14 (JST). These are taken from the spacecraft in the direction of Pisces. "Psc" is an abbreviation of Pisces. The field of view is 9°×7°. (Image credit: JAXA, Kyoto University, Japan Spaceguard Association, Seoul National University.)

Note 1: The Star Tracker is an instrument typically used for estimating the orientation of the spacecraft by measuring the position of surrounding stars. However, in this mode, it can be used to take images like a camera.
Note 2: The spacecraft position is usually estimated by communicating with the spacecraft using radio waves. This is known as "radio navigation". But just before Hayabusa2 arrives at Ryugu, the trajectory of the asteroid and spacecraft needs to be known as accurately as possible. We, therefore, use image data to measure the direction of Ryugu from Hayabusa2. Combining this with the radio navigation, the orbit of both asteroid and spacecraft can be estimated to greater precision. This is referred to as "optical navigation".

How to keep up with Hayabusa2 (http://www.planetary.org/blogs/emily-lakdawalla/2018/0525-keep-up-with-hayabusa2.html)

How to keep up with Hayabusa2

Hayabusa2 is approaching Ryugu! Here's how to stay on top of the mission.
As I write this, fewer than 21,000 kilometers separate the Hayabusa2 spacecraft from its asteroid target, Ryugu, and it's approaching the asteroid at a speed of 40 meters per second -- only about 150 kilometers per hour. I have always paired Hayabusa2 and OSIRIS-REx in my mind, because they are both sample-return missions approaching their target asteroids in summer 2018. But Hayabusa2 will already have touched down on its asteroid by the end of 2018, while OSIRIS-REx will still be surveying Bennu from a distance at the end of the year. It's time for those of us who've been sleeping on Hayabusa2 to wake up and pay attention!

HAYABUSA2 AT ASTEROID 1999 JU3


Hayabusa2's schedule is a little difficult to predict because the asteroid's shape isn't known yet; they'll be planning survey and touchdown activities in response to what they discover. With that disclaimer, here's the provisional schedule for the rest of 2018.
    [/li]
  • Early June: At a distance of 2500 kilometers, the "approach" phase officially begins, and ion engine operation ends. They will coast the rest of the way toward Ryugu. If you divide today's 21,000 kilometers by 0.04 kilometers per second, I get Hayabusa2 approaching to within 2500 kilometers of the asteroid on May 29 or 30, but of course they are using the ion engines now to slow down the rate at which they are closing with the asteroid.
  • June 21-July 5: Hayabusa2 arrives at Ryugu, approaching to within 20 kilometers.
  • End of July: Hayabusa2 descends to a distance of 5 kilometers to perform medium-altitude observations.
  • August: Hayabusa2 descends to only 1 kilometer to measure Ryugu's gravity close-up (necessary to prepare to land on it)
  • September-October: Period for first touchdown operation. One or more of Hayabusa2's three MINERVA-II rovers and/or theEuropean-built MASCOT lander (https://z5h64q92x9.net/proxy_u/en-ru.ru/https/www.esa.int/Our_Activities/Space_Engineering_Technology/Asteroid_Impact_Mission/Lander) may be released at this time.
  • November-December: Solar conjunction, no communications
    I won't reproduce the rest of the currently posted timeline (https://z5h64q92x9.net/proxy_u/en-ru.ru/www.hayabusa2.jaxa.jp/topics/mission_schedule_e/) because I bet there'll be changes to it between arrival and the planned departure date of November or December of 2019.
  • MASCOT mission animation from DLR (https://www.youtube.com/watch?v=h_BPJV2W4GU)
MASCOT (Mobile Asteroid Surface Scout) is an asteroid lander built by the German space agency DLR for the Hayabusa2 mission. It is tiny, only 30 by 30 by 20 centimeters in size, weighing 10 kilograms. It has an internal motion mechanism that will allow it to hop across the surface of asteroid Ryugu.

ЦитатаЯпонский зонд начал завершающий этап полета к астероиду, где будут взяты образцы пород
ТОКИО, 4 июня. /ТАСС/. Японский космический зонд "Хаябуса-2" ("Сокол-2") вышел на завершающий этап своего полета к астероиду Рюгу, на котором он должен совершить посадку. Об этом объявило в понедельник Аэрокосмическое агентство JAXA.
В воскресенье, как передает информационное агентство Kyodo (http://www.kyodonews.jp/), был отключен основной ионный двигатель зонда. Направление завершающего этапа полета будет корректироваться с помощью вспомогательного двигателя на химическом топливе. К астероиду аппарат должен подойти в период между 21 июня и 5 июля.
Рюгу диаметром всего 900 метров находится между Землей и Марсом. "Хаябуса-2" был запущен к астероиду в декабре 2014 года с космодрома на японском острове Танэгасима.
Зонд должен взять на Рюгу образцы пород и вернуться на Землю. Ученые надеются найти на астероиде следы воды и органических веществ, что может помочь в разгадке тайны распространения жизни во Вселенной. На Землю "Хаябуса-2" весом около 600 кг должен вернуться в конце 2020 года.
Этот аппарат представляет собой модифицированную версию первого "Сокола", который впервые в истории науки сумел доставить на Землю материалы, собранные на поверхности иного, нежели Луна, космического объекта. К удаленному от Земли на 336,5 млн км астероиду Итокава "Сокол-1" отправился с такой миссией в мае 2003 года. За семь лет своего полета с Земли и обратно зонд проделал самое длинное в истории человечества путешествие (преодолел 6 млрд км).

ЦитатаCompletion of forward cruise ion engine operation

(http://www.hayabusa2.jaxa.jp/img/mainv_hayabusa2.png)

Since January 10 this year (2018 ), the third phase of the ion engine operation has been underway. This was completed this week on June 3, ending the use of the ion engines for the outward approach towards asteroid Ryugu.

During the operation on June 3, the Hayabusa2's velocity was confirmed via Doppler data (the shift in radio wave frequency corresponding to the speed of the spacecraft along the line-of-sight from Earth) and the decision was made to stop ion engine operation at 14:59 JST at machine time (the time recorded by Hayabusa2 on-board clock). The telemetry data from the spacecraft received at 15:16 confirmed that ion engine operation has ended normally.

In this third phase of ion operation, the continuous operation time was about 2,426 hours, producing a velocity increase of 393 m/s (hourly speed of 1,400 km/hr).

From here on, accurate orbital determination of both the spacecraft and the asteroid will be made via radio and optical navigation as Hayabusa2 approaches Ryugu. We will return to report on the results of the ion engine operation and up-coming optical navigation soon.

МОСКВА, 7 июн - РИА Новости. Камера межпланетной станции "Хаябуса-2" получила первые снимки астероида Рюгю и передала их на Землю, что поможет пилотам выбрать оптимальный курс сближения с ним, сообщает сайт (http://www.hayabusa2.jaxa.jp/topics/20180607_e/) Японского космического агенства (JAXA).
"В тот момент, когда "Хаябуса" получила эти снимки, она находилась на расстоянии в 2600 километров от астероида. На такой дистанции каждый пиксель на картинке соответствует квадрату в 300 на 300 метров, что, к сожалению, пока не позволяет нам понять, какой формой обладает астероид", -- сообщили в JAXA.
Зонд "Хаябуса-2", целью которого является изучение и забор проб с астероида Рюгю, был запущен в космос в начале декабря 2014 года. Он вернет на землю первые 100% "чистые" пробы первичной материи Солнечной системы.
Предшественник аппарата, зонд "Хаябуса", был запущен в космос в мае 2003 года. Это единственный космический аппарат, совершивший посадку и взлет с поверхности космического тела за пределами системы Земля-Луна. В 2005 году он совершил посадку на астероид Итокава, однако из-за неполадок взятие проб грунта прошло не по плану.

© JAXA  Фотография астероида Рюгю, полученные зондом "Хаябуса-2"
Его наследник, как ожидают специалисты JAXA, вернется к Земле в конце 2020 года, если все процедуры по забору грунту пройдут по плану, и капсула с образцами материи не повредится при посадке на поверхность нашей планеты. 
Забор грунта, несмотря на то, что "Хаябуса-2" уже достигла Рюгю, произойдет совсем нескоро. Сначала зонд должен определить свою точную орбиту и скорректировать ее, если возникнет такая необходимость, а затем -- всесторонне изучить структуру недр и рельеф астероида.
Только после этого межпланетная станция сблизится с поверхностью Рюгю и сбросит на нее своеобразный "взрывпакет", который обнажит и выбросит нетронутый материал из недр астероида. "Хаябуса-2" соберет эту пыль и гальку, левитирующую в вакууме, во время второго пролета над этой точкой.
Первые снимки, полученные зондом вчера, стали первым шагом на пути к реализации этой задачи - они помогли научной команде "Хаябусы" понять, где находится зонд и проложить оптимальную траекторию сближения с астероидом. В ближайшее время астрономы надеются получить более детальные снимки Рюгю, на которых можно будет увидеть его форму и некоторые черты рельефа.

Our laser altimeter (LIDAR) onboard Hayabusa2 has been turned on for the first time in 2 years & is working well! LIDAR is used to calculate distance to a target. Here's a story from the Chiba Institute of Technology, Planetary Exploration Research Center:
http://www.hayabusa2.jaxa.jp/topics/20180611_e/

ЦитатаLIDAR turned on for the first time in two years

The laser altimeter (LIght Detection And Ranging: LIDAR) onboard Hayabusa2 calculates the distance to the target by measuring the time it takes for light from a lasar to scatter from the target surface and return to the spacecraft. This is used to check the position of the spacecraft, measure the roughness of the surface of the celestial body and obtain a measure of how reflective that surface is. Since there is no target to reflect light in outer space, LIDAR was turned off during cruising.

Now that Hayabusa2 is approaching Ryugu, LIDAR was turned on and confirmed to be working normally (health check) on June 6, 2018. Since this is the first power-on in two years, commands were gradually issued to the LIDAR system and normal response was confirmed. As Hayabusa2 is now far from Earth, every communication takes 16 minutes each way, even travelling at the speed of light. In order to see the response to a command, we had to wait for a 32 minute round-trip!

After about five hours of careful checks, LIDAR was confirmed to be working normally. However, since the distance to Ryugu is still about 2000km, we cannot measure the distance to the asteroid yet.

Hayabusa2 is getting closer to Ryugu every day. Soon, LIDAR should be able to measure the distance. We are looking forward to the day we recieve that data!

The LIDAR system onboard Hayabusa2 is developed and operated with cooperation from the National Astronomical Observatory of Japan (NAOJ)/ JAXA / Chiba Institute of Technology / University of Aizu / Nihon University, Osaka University.

We have carried out the 2nd optical navigation trajectory correction manoeuvre (TCM02). On June 11, 2018 at ~09:30 - 10:40 JST, the thrusters were fired several times to give Hayabusa2 an acceleration of 13 cm/s (x-direction), 1 cm/s (-y-direction), 26 cm/s (z-direction). [1/2]

The distance from the spacecraft to the asteroid during TCM02 was ~1320km and the relative speed after TCM02 was ~2.1m/s. Until now, Hayabusa2 was approaching Ryugu from the side. But the asteroid is now directly in front of the spacecraft, along the direction of travel. [2/2]

ЦитатаRyugu seen fr om a distance of 1500km

Hayabusa2 is continuing to approach asteroid Ryugu using optical navigation. Figure 1 shows Ryugu photographed by the ONC-T (Optical Navigation Camera - Telescopic) on June 10, 2018, from a distance of about 1500km. The celestial body shining brightly in the center of the image is Ryugu. Compared with images taken on June 6 (http://www.hayabusa2.jaxa.jp/topics/20180607_e/), the position in the sky (relative to background stars) wh ere Ryugu is visible has changed. The astronomical magnitude of Ryugu is now -5.7 mag.

Figure 1. asteroid Ryugu imaged using the ONC-T. The photograph was taken on June 10, around 12:50 JST. The field of view is 6.3 degrees x 6.3 degrees and the exposure time is 178 seconds. From the spacecraft, you can see Ryugu in the direction of the constellation, Gemini (Gem).

Figure 2 shows a photograph taken at approximately the same time but using an exposure of about 0.09 seconds. Here, only Ryugu is imaged as a point and the background stars are now too faint to be seen. In expanding the section of image that contains Ryugu, the asteroid can be seen to have a diameter of about 5 or 6 pixels but this is still not sufficient to see the shape. However, from this image is does seem that Ryugu is not elongated like Itokawa.

Hayabusa2 will continue to draw closer to Ryugu. Please keep following us for future images!

Note:
Does it seem strange that in the caption of the ONC images we refer to the "ground observation team"? Primarily before the launch of the spacecraft, the ground observation team observed Ryugu (which was then referred to as 1999 JU3) and other potential celestial bodies using ground-based telescopes. The team were responsible for providing important data for selecting prospective candidates for the Hayabusa2 mission. After Ryugu was sel ected as the destination for Hayabusa2, the team observed Ryugu (to get light curve and spectrum observation data) and used this to investigate the physical properties of the asteroid.

The images from ONC are now being used by the ground observation team to accurately measure the position of Ryugu based on the location of the background stars in the captured image. In addition, they also create images for the public that we can all see. Members of the ground observation team are led by Principal Investigator, Professor Masateru Ishiguro at Seoul National University and consist of about 30 researchers from many domestic and international organizations. In addition to Professor Ishiguro, Dr. Daisuke Kuroda from Kyoto University and Drs Shin-ichiro Okumura and Seitaro Urakawa fr om the Japan Spaceguard Association work on the ONC image analysis.

ЦитатаRyugu seen from a distance of 920km

Hayabusa2 is steadily approaching asteroid Ryugu. Figure 1 shows a photograph of Ryugu taken on June 13, 2018 with the ONC-T (Optical Navigation Camera - Telescopic) from a distance of about 920km. The celestial body shining brightly in the center of the frame is Ryugu. The movement of Ryugu (in comparison to the background stars) can be seen by comparing this image with those taken on June 6 and June 10. The brightness of Ryugu is now about -6.6 mag (astronomical magnitude: a logarithmic scale for the apparent brightness for an object).

Figure 2 shows the photograph taken with an exposure time of about 0.09 seconds. The part of the image that covers Ryugu is now about 10 pixels in diameter. We are describing the shape seen so far as a "dango"-type, as it looks like the round dango Japanese sweet dumpling made from rice flour (they taste delicious and we can recommend trying one). However, the shape does seem a little more angular.

ЦитатаАстероид Рюгю оказался похож по форме на "пышку", заявили в JAXA

МОСКВА, 14 июн - РИА Новости. Зонд "Хаябуса-2" получил новые фотографии астероида Рюгю, на которых можно увидеть, что он напоминает пышку или "пельмешек" по своей форме, сообщает JAXA (http://www.hayabusa2.jaxa.jp/topics/20180614_je/index_e.html).

"Хаябуса-2 медленно, но верно сближается с Рюгю. Сейчас зонд находится на расстоянии в 920 километров от его поверхности, что позволило нам получить фотографию, на которой диаметр астероида составляет около 10 пикселей. Если судить по этому снимку, он похож по форме на пышку или данго, сладкие шарики из рисового теста, запеченные на палочке", -- пояснили ученые.
Зонд "Хаябуса-2", целью которого является изучение и забор проб с астероида Рюгю, был запущен в космос в начале декабря 2014 года. Он вернет на землю первые 100% "чистые" пробы первичной материи Солнечной системы.

Японский аппарат достиг цели в начале июня и начал длительную процедуру торможения и сближения с астероидом. Первые фотографии Рюгю, полученные зондом на прошлой неделе, помогли астрономам уточнить положение "Хаябусы-2", но не позволили понять, какой формой и какими размерами обладает астероид.

Новые снимки, которые зонд отправил на Землю сегодня ночью, оказались более удачными. На них астероид занимает не несколько пикселей, а около сотни точек, что позволило планетологам дать первые оценки его формы.

Как подозревают ученые, Рюгю, скорее всего, имеет более угловатую форму и больше похож на "пельмешек", чем на круглый шарик данго или пышку, как на то указывает текущая фотография. Этот снимок, в свою очередь, стал особенным для команды "Хаябусы-2", так как ровно восемь лет назад на Землю вернулась его предшественница, межпланетная станция "Хаябуса".
Предшественник аппарата, зонд "Хаябуса", был запущен в космос в мае 2003 года. Это единственный космический аппарат, совершивший посадку и взлет с поверхности космического тела за пределами системы Земля-Луна. В 2005 году он совершил посадку на астероид Итокава, однако из-за неполадок взятие проб грунта прошло не по плану.

Его наследник, как ожидают специалисты JAXA, вернется к Земле в конце 2020 года, если все процедуры по забору грунту пройдут по плану, и капсула с образцами материи не повредится при посадке на поверхность нашей планеты.

Забор грунта, несмотря на то, что "Хаябуса-2" уже достигла Рюгю, произойдет совсем нескоро. Сначала зонд должен определить свою точную орбиту и скорректировать ее, если возникнет такая необходимость, а затем -- всесторонне изучить структуру недр и рельеф астероида.

Только после этого межпланетная станция сблизится с поверхностью Рюгю и сбросит на нее своеобразный "взрывпакет", который обнажит и выбросит нетронутый материал из недр астероида. "Хаябуса-2" соберет эту пыль и гальку, левитирующую в вакууме, во время второго пролета над этой точкой.

ЦитатаFrom a distance of about 700km, 
Ryugu's rotation was observed.


Using the ONC-T (Optical Navigation Camera - Telescopic), asteroid Ryugu was photographed continuously from June 14, 2018 at around 21:00 JST through to June 15, 2018 at around 05:10 JST. Figure 1 shows a looped animation of the 52 captured images.

The distance to Ryugu when the images were captured was between about 700 - 650 km. In these photographs, Ryugu is approximately 12 - 13 pixels in diameter. The animation in Figure 1 shows the photographs after image processing has been performed to smooth between the pixels so that the asteroid's surface looks smooth.

From this animation, you can see the asteroid surface appears to be strongly angled, and pitted with dents or craters. Also, the axis of rotation looks close to the vertical direction (perpendicular to the ecliptic plane in which the Earth orbits the Sun) in this image. The direction of rotation is retrograde, spinning in the opposite sense to the Earth and Sun, and to the direction of the planetary orbits. This information is very important for exploring the asteroid.

As we see the surface of Ryugu more clearly from now on, we will start to gain a more precise knowledge of the asteroid's properties.

МОСКВА, 18 июн - РИА Новости. Японская межпланетная станция "Хаябуса-2" получила серию из 52 фотографий, благодаря которым ученые впервые увидели, как вращается астероид Рюгю, что помогло уточнить его форму, сообщает (http://www.hayabusa2.jaxa.jp/topics/20180616je/index_e.html) JAXA.

"На этом видео можно увидеть, что астероид имеет резко угловатую форму и что он покрыт большим числом вмятин или кратеров. Что интересно, он вращается вокруг своей оси в противоположную сторону по сравнению с Землей и другими планетами. Это роднит его с Венерой и Ураном и делает потенциально уникальным малым небесным телом", -- заявили ученые.

Зонд "Хаябуса-2", целью которого является изучение и забор проб с астероида Рюгю, был запущен в космос в начале декабря 2014 года. Он вернет на землю первые 100% "чистые" пробы первичной материи Солнечной системы.

Японский аппарат достиг цели в начале июня и начал длительную процедуру торможения и сближения с астероидом. Первые фотографии Рюгю, полученные зондом на прошлой неделе, помогли астрономам уточнить положение "Хаябусы-2", но не позволили понять, какой формой и какими размерами обладает астероид.

Позже камеры зонда получили новые, более четкие фотографии астероида, которые показали, что он похож по форме на "пельмешек" или шарики данго, национальное японское блюдо. Новые фотографии, которые "Хаябуса-2" передала на Землю на минувших выходных, показали, что он имеет более угловатую форму и скорее больше похож на куб, чем на шар.

Это не стало неожиданностью для научной команды зонда, изначально отмечавшей, что астероид должен быть менее "круглым", чем он кажется на первых детальных фотографиях этого небесного тела. С другой стороны, необычная манера вращения и форма астероида могут сильно повлиять на то, когда и как будет совершена посадка микро-ровера и забор грунта с его поверхности.

Предшественник аппарата, зонд "Хаябуса", был запущен в космос в мае 2003 года. Это единственный космический аппарат, совершивший посадку и взлет с поверхности космического тела за пределами системы Земля-Луна. В 2005 году он совершил посадку на астероид Итокава, однако из-за неполадок взятие проб грунта прошло не по плану.

Его наследник, как ожидают специалисты JAXA, вернется к Земле в конце 2020 года, если все процедуры по забору грунту пройдут по плану, и капсула с образцами материи не повредится при посадке на поверхность нашей планеты.

Забор грунта, несмотря на то, что "Хаябуса-2" уже достигла Рюгю, произойдет совсем нескоро. Сначала зонд должен определить свою точную орбиту и скорректировать ее, если возникнет такая необходимость, а затем -- всесторонне изучить структуру недр и рельеф астероида.

Только после этого межпланетная станция сблизится с поверхностью Рюгю и сбросит на нее своеобразный "взрывпакет", который обнажит и выбросит нетронутый материал из недр астероида. "Хаябуса-2" соберет эту пыль и гальку, левитирующую в вакууме, во время второго пролета над этой точкой. Позже зонд высадит на поверхность астероида миниатюрный ровер, который проработает на его поверхности около суток и соберет данные о его структуре.

ЦитатаRyugu seen from 330-240km

The ONC-T (Optical Navigation Camera - Telescopic) captured images of Ryugu on June 17, 2018 at around 15:00 JST and June 18 at around 06:00 JST. At 15:00 JST on June 17, the distance to Ryugu was approximately 330 km, which had decreased to 240 km by June 18 at 06:00 JST.

The following figures show the original images taken by the ONC-T, without any pixel smoothing. The order of the photographs is not chronological, but show the sequential rotation of the asteroid. The change in distance is compensated by keeping the size of the asteroid constant through the image set.

Comment by Project Scientist, Sei-ichiro Watanbe
The vertical direction in these images is tilted by 10 degrees counterclockwise compared to the vertical direction of the orbital plane of Ryugu. From looking between the multiple images in this set, you can see that the vertical direction is nearly perpendicular to the plane of revolution of the asteroid. We call this direction the asteroid's axis of rotation. The direction of the rotation is reversed compared to the Earth, with a rotation period of about 7.5 hours.

The diameter of Ryugu is about 900m, which is consistent with the prediction from ground observations. However, since the distance between the spacecraft and Ryugu is not precisely determined, there is still some uncertainty in the exact diameter at this time.

The shape of the asteroid looks like a spinning top (called a "Coma" in Japanese), with the equatorial part wider than the poles. This form is seen in many small asteroids that are rotating at high speed. Observed by radar from the ground, asteroid Bennu (the destination of the US mission, OSIRIS-REx), asteroid Didymous (the target of the US DART project), and asteroid 2008 EV5 that is approaching the Earth, all have a similar shape.

On the surface of asteroid Ryugu, you can see a number of crater-like round recessed landforms. In the first image, one large example can be seen with a diameter exceeding 200m. This moves to the left and darkens as the asteroid rotates and the lower part becomes cast in shadows.

The bulge at the equator forms a ridge around the asteroid like a mountain range. Outside this, the surface topology appears very ridge-shaped and rock-like bulges are also seen. These details should become clearer as the resolution increases in the future.
Comment by Mission Manager, Makoto Yoshikawa
When I saw these images, I was surprised that Ryugu is very similar in shape to both the destination of the US OSIRIS-REx mission, asteroid Bennu, and also the target of the previously proposed MarcoPolo-R mission by Europe, asteroid 2008 EV5. Bennu and 2008 EV5 are about half the diameter (and 1/8 the volume) of Ryugu, with rotation periods about half as long. In other words, these celestial bodies are small and rotating fast compared to Ryugu. On the other hand, Bennu is a B-type asteroid, which is very similar to C-type asteroids such as 2009 EV5 and Ryugu. Therefore there should also be common properties due to the asteroid type. So we have both differences and similarities that have combined to produce very similar shapes... why is that? I think this is very interesting. So far, the asteroids we have explored have been different in shape, so Ryugu and Bennu could be the first time two similar-shaped asteroids have been examined. It will be interesting to clarify exactly what this similarity means scientifically.

If the axis of rotation for Ryugu is close to the vertical direction in this image, there is a big advantage as it will be possible to know almost the entire appearance of Ryugu at an early stage after arrival. This makes the project planning easier. However, it is also possible that potential landing sites may be limited to the equator of Ryugu. I hope we can find a suitable place to set down the lander and rovers.

МОСКВА, 19 июн - РИА Новости. Новые фотографии астероида Рюгю, полученные камерами зонда "Хаябуса-2" с расстояния в две сотни километров от его поверхности, говорят о том, что он похож по форме на гигантский кубик сахара, покрытый вмятинами кратеров, сообщает (http://www.hayabusa2.jaxa.jp/topics/20180619je/index_e.html) JAXA.

"Когда я увидел эти снимки, я был очень удивлен, что Рюгю похож по форме на толстую "юлу", как и два других астероида - Бенну, к которому летит зонд OSIRIS-REx, и 2008 EV5, куда может отправиться миссия MarcoPolo-R. Несмотря на различия в размерах, все они имеют схожий химический состав. Нам будет невероятно интересно узнать, насколько случайно это совпадение", -- заявил Макото Йосикава (Makoto Yoshikawa), руководитель миссии в JAXA.
Зонд "Хаябуса-2", целью которого является изучение и забор проб с астероида Рюгю, был запущен в космос в начале декабря 2014 года. Он вернет на землю первые 100% "чистые" пробы первичной материи Солнечной системы.

Японский аппарат достиг цели в начале июня и начал длительную процедуру торможения и сближения с астероидом. Первые фотографии Рюгю, полученные зондом в первых числах месяца, помогли астрономам уточнить положение "Хаябусы-2", но не позволили понять, какой формой и какими размерами обладает астероид.

Форма астероида неоднократно "менялась" по мере сближения зонда с небесным телом и увеличения качества снимков. Сначала ученым казалось, что он был похож на "пельмешек" или шарик данго, национальной японской сладости, однако новые серии снимков и своеобразный видеоролик показали, что он имеет более угловатую форму.

Новые фотографии, которые Йосикава и его команда получили вчера и позавчера с расстояния в 330 и 245 километров от поверхности Рюгю, указали на то, что он похож по форме на кубик сахара, вращающийся на одном из углов, или на очень толстую и "квадратную" юлу.

Помимо общих очертаний астероида, ученым удалось узнать скорость его вращения - он совершает один оборот вокруг своей оси за семь часов и тридцать минут, и найти множество крупных кратеров на его поверхности, диаметр которых достигает 100-200 метров.

"Если ось вращения астероида расположена в том же направлении, что и вертикальные линии на наших фотографиях, то тогда это станет большим плюсом для нас - мы сможем изучить всю поверхность Рюгю сразу же после прибытия к астероиду. С другой стороны, такая пространственная конфигурация может резко ограничить наши возможности по посадке ровера и лендера на его поверхность. Я надеюсь, что их удастся решить", -- заключает Йосикава.

Предшественник аппарата, зонд "Хаябуса", был запущен в космос в мае 2003 года. Это единственный космический аппарат, совершивший посадку и взлет с поверхности космического тела за пределами системы Земля-Луна. В 2005 году он совершил посадку на астероид Итокава, однако из-за неполадок взятие проб грунта прошло не по плану.

Его наследник, как ожидают специалисты JAXA, вернется к Земле в конце 2020 года, если все процедуры по забору грунту пройдут по плану, и капсула с образцами материи не повредится при посадке на поверхность нашей планеты.

Забор грунта, несмотря на то, что "Хаябуса-2" уже достигла Рюгю, произойдет совсем нескоро. Сначала зонд должен определить свою точную орбиту и скорректировать ее, если возникнет такая необходимость, а затем -- всесторонне изучить структуру недр и рельеф астероида.

Только после этого межпланетная станция сблизится с поверхностью Рюгю и сбросит на нее своеобразный "взрывпакет", который обнажит и выбросит нетронутый материал из недр астероида. "Хаябуса-2" соберет эту пыль и гальку, левитирующую в вакууме, во время второго пролета над этой точкой. Позже она спустит на поверхность Рюгю миниатюрный ровер, который проработает на астероиде несколько десятков часов.

ЦитатаRyugu seen from a distance of 220-100km

The onboard ONC-T (Optical Navigation Camera - Telescopic) imaged Ryugu from June 18, 2018 at around 12:00 JST to June 20 at around 19:00 JST. At 12:00 JST on June 18, the distance between the spacecraft and asteroid was about 220km, and this decreased to about 100km by June 20, 19:00 JST.

The following image in Figure 1 is the original photograph without any pixel smoothing. The order of the images is the chronological order in which they were captured. The size of the asteroid remains proportional to the distance (no size correction; the asteroid appears smaller when more distant.)

Comment by the ONC PI (Principal Investigator), Seiji Sugita

"The varied geography of Ryugu"

As we approached Ryugu and were able to distinguish individual features in the asteroid's topology, it became clear that Ryugu has a land of rich terrain. Numerous clusters of rock roll on the surface. Among these, a large rocky mass (about 150m across) stands out on the upper part of Ryugu due to its brighter color (higher reflectivity). The belt-shaped ring of peaks that surround the equator are also slightly brighter than their surroundings. This color difference may reflect a difference in material composition and the size of the particles that form the rock. We can also see many sunken regions that look like craters. These depressions may have been made in collisions with other celestial bodies. A structure that looks like a grove is also visible.

The existence of such varied topographies is an indication that Ryugu has undergone a complex evolutionary history. It is generally believed that small asteroids that are less than 1km, such as Ryugu, were created fairly recently in the Solar System's history (within several hundred million years) during the fragmentation of a larger parent body. Ryugu's terrain will tells us about the division from the parent body and the asteroid's subsequent evolution.

In the final days of a three-and-a-half year pursuit, Japan's Hayabusa 2 sample return spacecraft is beaming back clearer images of asteroid Ryugu, an unexplored object that scientists say resembles a spinning top or dumpling nearly 180 million miles fr om Earth.

The approaching Hayabusa 2 spacecraft is revealing Ryugu for the first time, sharpening views of an asteroid scientists hope to sample later this year. The nearly 3,000-foot (900-meter) wide asteroid has never been visited by a space mission before now.
Launched aboard a Japanese H-2A rocket on Dec. 3, 2014, Hayabusa 2 is Japan's second space mission dedicated to bringing samples fr om an asteroid back to Earth. The mission's predecessor, named Hayabusa, returned microscopic specimens from asteroid Itokawa in 2010 after a series of malfunctions prevented it from capturing the planned amount of material.

Hayabusa 2 launched with several major improvements, and instead of going to a stony S-type asteroid like Itokawa, mission planners directed the new mission to Ryugu, a C-type asteroid rich in carbon and other building blocks that formed the solar system's planets more than 4.5 billion years ago.

"Hayabusa was a technological demonstrator, so its main purpose was technology and the second purpose is science," said Makoto Yoshikawa, Hayabusa 2's mission manager at the Japan Aerospace Exploration Agency, in a phone interview last week with Spaceflight Now. "For Hayabusa 2, science is the main purpose. That's the big difference.

"For both missions, we wanted to learn about the origins of the solar system, but for Hayabusa 2, we want to understand the organic matter and water at the beginning of the solar system," Yoshikawa said. "This is the major point for science."

As of Wednesday, Hayabusa 2 was around 50 miles (80 kilometers) from Ryugu. The spacecraft was closing the distance to the asteroid at a rate of a little more than a foot per second, a fraction of the speed of a typical walking pace.

Hayabusa 2 and Ryugu are currently located more than 176 million miles (284 million kilometers) from Earth.

Named for a dragon's palace in a famous Japanese fairy tale, asteroid Ryugu completes one circuit of the sun every 1.3 years, and its path briefly brings it inside Earth's orbit, making Ryugu a potentially hazardous asteroid.

The Hayabusa 2 spacecraft switched off its ion engines for the final time June 3, completing a near-continuous firing since January which reshaped the probe's orbit around the sun to match that of Ryugu. The ion engines consume xenon propellant and generate low levels of thrust, but their fuel efficiency allow the thrusters to operate for long durations.

Since turning off ion propulsion, Hayabusa 2's conventional hydrazine-fueled thrusters have conducted several burns to fine-tune the craft's final approach to Ryugu. The trajectory correction maneuvers have slowed Hayabusa 2's closing rate and steered the probe in a zig-zap motion intended to help ground teams pinpoint the asteroid's exact location by mapping its movement against a backdrop of stars.

The spacecraft's optical navigation camera is capturing better views of Ryugu every day, showing scientists surface markings, craters, and the asteroid's shape.

"Of course, this is the first time that we've seen Ryugu, so at first we want to know its shape and surface features," Yoshikawa said. "Also, we want to know the spin orientation."

It turns out Ryugu rotates once every 7.6 hours, about the same speed which scientists estimated from ground-based observations. But Ryugu was too small to allow telescopes on Earth to see its shape until Hayabusa 2 moved close this month.

"The shape of the asteroid looks like a spinning top (called a 'coma' in Japanese), with the equatorial part wider than the poles," wrote Sei-ichiro Watanabe, Hayabusa 2's project scientist, in an upd ate posted on JAXA's website earlier this week. "This form is seen in many small asteroids that are rotating at high speed."

Scientists have noticed crater-like recessed landforms around Ryugu, and a bright rugged feature is visible on the upper part of the asteroid, as viewed from Hayabusa 2.

"As we approached Ryugu and were able to distinguish individual features in the asteroid's topology, it became clear that Ryugu has a land of rich terrain," wrote Seiji Sugita, principal investigator on Hayabusa 2's optical navigation camera. "Numerous clusters of rock roll on the surface. Among these, a large rocky mass (about 150 meters across) stands out on the upper part of Ryugu due to its brighter color (higher reflectivity).

"The belt-shaped ring of peaks that surround the equator are also slightly brighter than their surroundings," Sugita wrote. "This color difference may reflect a difference in material composition and the size of the particles that form the rock. We can also see many sunken regions that look like craters. These depressions may have been made in collisions with other celestial bodies."

Ryugu's "spinning top" appearance resembles asteroid Bennu, the target of NASA's OSIRIS-REx spacecraft set to arrive there later this year.

Bennu is roughly half the size of Ryugu, but scientists had better imagery of Bennu from a passage near Earth that allowed radars to bounce signals off the asteroid and reveal its shape. Researchers believe both asteroids contain lots of carbon, an essential element of organic compounds, but Bennu has a slightly different chemical signature, making it a rare B-type asteroid.

"So we have both differences and similarities that have combined to produce very similar shapes... why is that?" Yoshikawa wrote on JAXA's website. "I think this is very interesting. So far, the asteroids we have explored have been different in shape, so Ryugu and Bennu could be the first time two similar-shaped asteroids have been examined. It will be interesting to clarify exactly what this similarity means scientifically."

Members of JAXA's Hayabusa 2 team and NASA's OSIRIS-REx team are collaborating in their asteroid exploration endeavors. The space agencies have agreed to share asteroid samples brought to Earth by Hayabusa 2 and OSIRIS-REx, and three U.S. scientists on the OSIRIS-REx team are assigned as co-investigators on the Japanese mission. In return, three Japanese researchers formally joined the OSIRIS-REx team.

At first glance, Ryugu "looks like the spinning top like we think Bennu looks like," said Dante Lauretta, principal investigator on the OSIRIS-REx mission from the University of Arizona.

"They didn't know that," Lauretta told Spaceflight Now. "They didn't have the radar data for Ryugu like we had for Bennu. If it's a spinning top, that is a huge relief for me actually because we have designed this mission around that shape -- all the observation plans, all the orbital design, everything is based on it being that spinning top."

"To see Ryugu come into focus with that kind of shape, I'm like, OK, that just reduces the uncertainty that we got the shape wrong on Bennu, and we're probably really good in terms of planning moving forward."

Ryugu's gravity field is 60,000 times weaker than Earth's, but the asteroid's light gravitational tug is already exerting its influence on Hayabusa 2. Navigators aim to have Hayabusa 2 at a point around 12 miles, or 20 kilometers, from the asteroid June 27, officially marking the mission's arrival.

Then Hayabusa 2's scientific instruments, which include a camera suite, a laser designed to measure topography, and a near-infrared spectrometer to study Ryugu's composition, will begin their reconnaissance of the asteroid.

"At first we will be at 20 kilometers, but at the end of July we will approach to within 5 kilometers (3 miles) of the surface, so we will have much more detailed surface images," Yoshikawa told Spaceflight Now. "Also, in August, we will measure the gravity of Ryugu, and in that case we will send the spacecraft down to 1 kilometer (about 3,300 feet) from the surface."

After the initial survey, Japanese scientists will decide in August wh ere to send Hayabusa 2 to collect the first of three samples from Ryugu. The mission's first touch-and-go landing on Ryugu is set for September or October.

Hayabusa 2's sampling mechanism works by shooting a small bullet into the asteroid after it descends to the surface. The projectile will fire while Hayabusa 2's sampling funnel is in contact with the asteroid, and engineers the energy imparted by the bullet will blast bits of gravelly rock through a tube into a collection chamber for storage inside the mission's return capsule.

Hayabusa 2 carries four landers, including a 22-pound (10-kilogram) robot named MASCOT built by the same German-French team that managed the Philae comet lander deployed from the European Space Agency's Rosetta mission for a touchdown on comet 67P/Churyumov-Gerasimenko in 2014.

Yoshikawa said MASCOT should be released for its landing on Ryugu in early October. Carrying its own set of instruments and a camera, the robot is designed to bounce to several locations on the asteroid.

Three other landing craft built in Japan will also descend to the asteroid during Hayabusa 2's mission.

The OSIRIS-REx spacecraft is se t to arrive in the vicinity of Bennu around Dec. 3, but the mission's ground team will spend a year investigating the asteroid before going in for a sample collection in July 2020, with the specimens se t to return to Earth in 2023.

"They're going a lot more quickly than we are," Lauretta said. "We're not going to be making a sample site selection until more than a year from now. So we're going to map and map, and think and process and analyze. They're going to go in and have a site sel ected by mid-August, less than two months from now. That's a very different approach to the issue. I'm curious and excited to see how they go about that.

"The most interesting aspect is how their touch-and-go sampling proceeds," Lauretta said. "That's wh ere most of our uncertainty lies on the mission. What is the nature of the asteroid surface? How compliant is it? What are the cohesive forces? How much torque is going to be placed on the spacecraft when we make contact? They're going to do all that for us. We have a data-sharing agreement. We'll be able to see what happened, and hopefully refine and improve our sampling design as a result of that."

One of the three samples to be collected by Hayabusa 2 will come from material excavated fr om beneath the asteroid's surface. Hayabusa 2 will use explosives to fire a copper impactor into the asteroid to carve an artificial crater, exposing underground pristine rocks for the probe to pick up during a touch-and-go maneuver.

Each of Hayabusa 2's three asteroid specimens will go into a separate chamber inside the craft's sample return canister.

Hayabusa 2 is scheduled to depart Ryugu by the end of 2019, and the spacecraft will separate its sample carrier for re-entry and a parachute-slowed landing in Australia in December 2020. If all goes according to plan, Hayabusa 2 should bring back at least a gram of asteroid material for detailed analysis in laboratories on Earth.

Hayabusa-2 trajectory file has been updated. There is a gap between Jun 22 1700 and Jun 23 2100. I think they got an improved nav solution on Jun 23 that showed them 15 km further from Ryugu than previously thought. Here is a clearer plot of the old and new files' range vs time

Note the different slopes of the red and blue in the Jun24-26 and 26-27 velocity segments. I think this may reflect a lower Ryugu mass used in their new prediction (less acceleration between burns)

Comment by Project Manager, Yuichi Tsuda

The shape of Ryugu is now revealed. From a distance, Ryugu initially appeared round, then gradually turned into a square before becoming a beautiful shape similar to fluorite [known as the 'firefly stone' in Japanese]. Now, craters are visible, rocks are visible and the geographical features are seen to vary from place to place. This form of Ryugu is scientifically surprising and also poses a few engineering challenges.

First of all, the rotation axis of the asteroid is perpendicular to the orbit. This fact increases the degrees of freedom for landing and the rover decent operations. On the other hand, there is a peak in the vicinity of the equator and a number of large craters, which makes the selection of the landing points both interesting and difficult. Globally, the asteroid also has a shape like fluorite (or maybe an abacus bead?). This means we expect the direction of the gravitational force on the wide areas of the asteroid surface to not point directly down. We therefore need a detailed investigation of these properties to formulate our future operation plans.

The Project Team is fascinated by the appearance of Ryugu and morale is rising at the prospect of this challenge. Together with all of you, we have become the first eyewitnesses to see asteroid Ryugu. I feel this amazing honor as we proceed with the mission operations.

ЦитатаЗонд "Хаябуса-2" нашел загадочную гору на поверхности астероида Рюгю

МОСКВА, 25 июн - РИА Новости. Новые фотографии астероида Рюгю, полученные с расстояния в 40 километров, указывают на странный характер его вращения, большое число гравитационных аномалий и существование необычной горы на его экваторе. Все это усложнит посадку зонда "Хаябуса-2" на его поверхность, заявляют в JAXA (http://www.hayabusa2.jaxa.jp/topics/20180625je/index_e.html).

"Теперь мы знаем, что астероид "лежит на боку" - его ось вращения перпендикулярна орбите. С одной стороны, это облегчает нам посадку, но с другой стороны, мы нашли на экваторе астероида множество крупных кратеров и гору, которые усложнят ее. Вдобавок, сила гравитации не во всех регионах Рюгю оказалась направлена строго "вниз", -- заявил Юити Цуда (Yuichi Tsuda), один из руководителей миссии.
Зонд "Хаябуса-2", целью которого является изучение и забор проб с астероида Рюгю, был запущен в космос в начале декабря 2014 года. Он вернет на землю первые 100% "чистые" пробы первичной материи Солнечной системы.

Японский аппарат достиг цели в начале июня и начал длительную процедуру торможения и сближения с астероидом. Форма астероида неоднократно "менялась" по мере сближения зонда с небесным телом и повышения качества снимков.

Сначала ученым казалось, что он был похож на идеальный шар, потом - на "пельмешек" или шарик данго, национальной японской сладости. Более поздние серии снимков и своеобразный видеоролик, полученные "Хаябусой-2" в середине июня, показали, что он имеет более угловатую форму и похож на кубик сахара или кристалл шпата.

Предшественник аппарата, зонд "Хаябуса", был запущен в космос в мае 2003 года. Это единственный космический аппарат, совершивший посадку и взлет с поверхности космического тела за пределами системы Земля-Луна. В 2005 году он совершил посадку на астероид Итокава, однако из-за неполадок взятие проб грунта прошло не по плану.

Его наследник, как ожидают специалисты JAXA, вернется к Земле в конце 2020 года, если все процедуры по забору грунту пройдут по плану, и капсула с образцами материи не повредится при посадке на поверхность нашей планеты.

Забор грунта, несмотря на то, что "Хаябуса-2" уже достигла Рюгю, произойдет совсем нескоро. Сначала зонд должен определить свою точную орбиту и скорректировать ее, если возникнет такая необходимость, а затем -- всесторонне изучить структуру недр и рельеф астероида.

Только после этого межпланетная станция сблизится с поверхностью Рюгю и сбросит на нее своеобразный "взрывпакет", который обнажит и выбросит нетронутый материал из недр астероида. "Хаябуса-2" соберет эту пыль и гальку, левитирующую в вакууме, во время второго пролета над этой точкой.

Наличие крупных впадин и гор на поверхности Рюгю, по словам Цуды, стало большим сюрпризом для ученых по нескольким причинам. Во-первых, их присутствие говорит о сложной геологической истории астероида, чье существование, как считали ученые раньше, исключалось теорией формирования таких тел.

Во-вторых, связанные с ними гравитационные аномалии значительно усложнят дальнейшее сближение "Хаябусы-2" с Рюгю, забор грунта и высадку микроровера на его поверхность. Тем не менее, научная команда зонда, как отмечает ее руководитель, полна оптимизма и уверена в том, что зонд преодолеет все подобные трудности.

Hayabusa2 Rendezvous with Ryugu
June 27, 2018 (JST)

National Research and Development Agency
Japan Aerospace Exploration Agency (JAXA)
JAXA confirmed Hayabusa2, JAXA's asteroid explorer rendezvoused with Ryugu, the target asteroid. 

On June 27, 2018, JAXA operated Hayabusa2 chemical propulsion thrusters for the spacecraft's orbit control.*
The confirmation of the Hayabusa2 rendezvous made at 9:35 a.m. (Japan Standard Time, JST) is based on the following data analyses;
    [/li]
  • The thruster operation of Hayabusa2 occurred nominally
  • The distance between Hayabusa2 and Ryugu is approximately 20 kilometers
  • Hayabusa2 is able to maintain a constant distance to asteroid Ryugu
  • The status of Hayabusa2 is normal
From this point, we are planning to conduct exploratory activities in the vicinity of the asteroid, including scientific observation of asteroid Ryugu and surveying the asteroid for sample collection.

*Hayabusa2 operation hours: 7:00 a.m. (JST) through 3:00 p.m. (JST), June 27. The thruster operation was pre-programmed in the event sequence earlier on the day and the command was automatically executed.

ЦитатаJapanese spacecraft reaches asteroid after three-and-a-half-year journey
June 28, 2018 (https://spaceflightnow.com/2018/06/) | Stephen Clark (https://spaceflightnow.com/author/stephen-clark/)

Japan's robotic Hayabusa 2 spacecraft arrived Wednesday at asteroid Ryugu, a diamond-shaped object more than a half-mile wide where the probe will attempt a brief landing later this year to collect rock specimens for return to Earth.

After creeping up to the asteroid at an ever-slowing pace, thrusters on the Hayabusa 2 spacecraft stopped its approach Wednesday at a distance of about 12 miles, or 20 kilometers, according to the Japan Aerospace Exploration Agency.

The milestone marked the conclusion of a three-and-a-half-year voyage spanning nearly 2 billion miles (3.2 billion kilometers) since Hayabusa 2's launch fr om southern Japan on an H-2A rocket in December 2014.

The space probe and asteroid Ryugu, seen up-close for the first time, are currently located roughly 177 million miles (285 million kilometers) from Earth. Under remote control from engineers and scientists in Japan, Hayabusa 2 will spend the next few weeks surveying Ryugu, moving closer in a sequence of maneuvers to obtain higher-resolution imagery and data on the asteroid's gravity field.

"The shape of Ryugu is now revealed," wrote Yuichi Tsuda, Hayabusa 2's project manager at JAXA. "From a distance, Ryugu initially appeared round, then gradually turned into a square before becoming a beautiful shape similar to fluorite [known as the 'firefly stone' in Japanese].

"Now, craters are visible, rocks are visible and the geographical features are seen to vary from place to place," Tsuda wrote. "This form of Ryugu is scientifically surprising and also poses a few engineering challenges."

Hayabusa 2 will try to capture at least a gram of rock samples from Ryugu on three touch-and-go landing attempts, beginning as soon as early October. In late 2019, the spacecraft will depart the asteroid and head for Earth, dropping its sample-carrying re-entry canister for a parachute-assisted landing in South Australia in December 2020.

Scientists said Ryugu's rotation is perpendicular to its orbit, which is good news for plans later this year to deploy a series of landers and tiny rovers on the asteroid, beginning with the deployment in October of the 10-pound (22-kilogram) MASCOT vehicle developed by German and French engineers.

The asteroid completes one rotation every 7.6 hours, and its orbit takes it around the sun once every 1.3 years. Ryugu's orbit crosses the path of Earth around the sun, making it a potentially hazardous asteroid.

"On the other hand, there is a peak in the vicinity of the equator and a number of large craters, which makes the selection of the landing points both interesting and difficult," Tsuda wrote.

The shape of Ryugu also suggests it may have an uneven gravity field, which is estimated to be around 60,000 times weaker than Earth's, according to Tsuda.

"The project team is fascinated by the appearance of Ryugu and morale is rising at the prospect of this challenge," Tsuda wrote. "Together with all of you, we have become the first eyewitnesses to see asteroid Ryugu. I feel this amazing honor as we proceed with the mission operations."

All of Hayabusa 2's science instruments are functioning as designed. The sensors include a camera suite, a laser designed to measure topography, and a near-infrared spectrometer to study Ryugu's composition.

"At the end of July we will approach to within 5 kilometers (3 miles) of the surface, so we will have much more detailed surface images," said Makoto Yoshikawa, Hayabusa 2's mission manager, in an interview with Spaceflight Now earlier this month. "Also, in August, we will measure the gravity of Ryugu, and in that case we will send the spacecraft down to 1 kilometer (about 3,300 feet) from the surface."

After the initial survey, Japanese scientists will decide in August wh ere to send Hayabusa 2 to collect the first of three samples from Ryugu.

Hayabusa 2 will not go into orbit around Ryugu. Instead, the probe will follow trajectories around the asteroid, similar to the way a rendezvousing spacecraft approaches the International Space Station.

Since switching off its ion propulsion system in early June, Hayabusa employed hydrazine-fueled rocket thrusters to follow a zig-zag pattern toward Ryugu, taking range and bearing measurements to fine-tune its navigation to the asteroid. There was some uncertainty in the asteroid's exact position before Hayabusa 2's arrival.

The spacecraft's telescopic camera also scanned for moons and other debris accompanying Ryugu, but found no evidence of any companions.

In an interview with BBC News on Wednesday, Yoshikawa said the sampling maneuvers will the be the riskiest part of the Hayabusa 2 mission.

"The most difficult part is getting the sample," Yoshikawa told BBC News. "It is a little risky because we cannot operate from the Earth because there is a time delay, so the spacecraft must move by itself. The spacecraft has autonomous functions, but it's very risky because the surface of Ryugu is not so smooth."

We have three touchdowns (planned)," he said. "The first one is maybe in October. The second is maybe next year in February or March.

"So we have two chances, and actually one more," he told BBC News. "Hayabusa 2 has an impactor which will create a small crater on the surface of the asteroid. If we can make a small crater, then the spacecraft will touch down at the crater to get subsurface material."

Hayabusa 2 is one of two robotic asteroid missions arriving at distant objects this year. NASA's OSIRIS-REx spacecraft, which launched in September 2016, is scheduled to arrive at asteroid Bennu on Dec. 3 to collect its own samples to bring back to Earth.

Hayabusa 2 is a follow-up to Japan's Hayabusa mission, which collect less than a milligram of sample from the stony S-type asteroid Itokawa in 2005 and returned the material to Earth in 2010. But Hayabusa ran into numerous difficulties, including a fuel leak and a malfunction in its sampling mechanism, causing it to collect much less material than originally planned.

"Hayabusa was a technological demonstrator, so its main purpose was technology and the second purpose is science," Yoshikawa said in an interview with Spaceflight Now. "For Hayabusa 2, science is the main purpose. That's the big difference."

Ryugu is a primitive C-type asteroid that contains organic materials scientists believe are leftovers from the birth of the solar system.

"For both missions, we wanted to learn about the origins of the solar system, but for Hayabusa 2, we want to understand the organic matter and water at the beginning of the solar system," Yoshikawa said. "This is the major point for science."

Цитата[SIZE=8]Arrival at Ryugu![/SIZE]

1302 days after the launch fr om Tanegashima Space Center on December 3, 2014, Hayabusa2 has finally arrived at the target asteroid Ryugu. The arrival time was 9:35 am JST on June 27, 2018. Fr om here, we can begin to fully explore Ryugu.

After the end of the ion engine operations on June 3, 2018, Hayabusa2 began the final asteroid approach phase. Optical navigation was used to precisely aim for the asteroid's location. During the approach, the chemical propulsion thrusters were used to perform nine Trajectory Correction Maneuvers (TCM) to control the velocity of the spacecraft, with a tenth TCM made at the above time for arrival. After the final TCM10, the relative speed between Hayabusa2 and Ryugu was 1 cm/s or less and arrival at the asteroid was declared.

(http://www.hayabusa2.jaxa.jp/topics/20180629je/img/fig1e.jpg)
Figure 1: Doppler data during the arrival at Ryugu. The vertical axis shows the deviation from the planned value for the spacecraft's speed away from the Earth at arrival. The horizontal axis is the time on June 27, 2018.

Figure 1 shows Doppler data at the time of arrival. The Doppler data can estimate the speed of the spacecraft along the line-of-sight from the Earth (i.e. the speed along a straight line connecting our planet to Hayabusa2) using the frequency of radio waves received from the spacecraft. In Figure 1, the difference between the measured value and the planned value for the orbital speed at arrival is shown before and after the final TCM. (The value plotted on the vertical axis is actually double that difference.) After the TCM, the speed difference has become nearly zero, indicating that the relative speed with respect to Ryugu is almost zero as planned. The time of the TCM in Figure 1 is not 9:35 am JST since the spacecraft is at a distance of about 1.9 astronomical units (about 280 million km), and information takes about 16 minutes to transmit.

After viewing the Doppler data, Project Manager Yuichi Tsuda checked the information (telemetry data) from the spacecraft and confirmed arrival at asteroid Ryugu at 09:54 JST. We then took a group photo to commemorate the moment (Figure 2).

Now at a distance of about 20 km, the environment of Ryugu is clearly visible. Figure 3 is the image of Ryugu captured by the ONC-T (Optical Navigation Camera - Telescopic) on June 26, the day before arrival. You can easily see the shape is like that of an abacus bead, with large and small craters and many boulders.

The images of Ryugu shared so far have shown a surface with a whitish color, as in Figure 3. But what is the actual color? The ONC-T can take images with light within a specific wavelength band using seven different filters. By carefully combining this data, a natural color image can be created. Figure 4 shows color photographs of both the Earth and Ryugu created in this same way.

Figure 4: The Earth and Ryugu photographed by the ONC-T. The Earth image was taken immediately after the Earth swing-by (December 4, 2015). The natural color image of Ryugu was created from the multiband image taken on June 21, 2018 using the b, v and w filters (wavelength 0.48, 0.55, 0.70 microns).
Image credit ※: JAXA, University of Tokyo, Kochi University, Rikkyo University, Nagoya University, Chiba Institute of Technology, Meiji University, University of Aizu, AIST.


As you can see from Figure 4, the actual Ryugu is a very dark object. In ground observations of the asteroid, the albedo (reflectivity of light) of Ryugu was estimated to be just 0.05, suggesting this was a dark object which the images from the spacecraft now support.

From now on, Hayabusa2 will stay near Ryugu, observe the asteroid, release the lander and rovers, touch down and perform the impact experiment. Since these mission operations differ considerably from the activities prior to arrival, we created a new mission logo for Hayabusa2 (Figure 5). The color has changed from a system of blues to pink and purple. The outermost vermilion shades represent the palace of Ryugu; the location in the Japanese folk tale of Urashima Taro that asteroid Ryugu takes its name. The inner purple is for the nobles of the palace and Princess Otohime, while the central light blue is for the princess's feathered robe. These changing colors show the enthusiasm of the Project members to explore the whole of Ryugu. The logo also shows an illustration of the asteroid, with the large craters and boulders that have now been seen on the surface.

The time for exploration has finally come. There are a variety of challenging and long operations ahead, but the plan is to thoroughly investigate asteroid Ryugu.

Our last image to show is a movie wh ere we can watch Ryugu become steady bigger as we approach (Figure 6).

Если на снимке Рюге освещена Солнцем, то логично предположить, что "на обратной стороне" Рюге ночь. А поскольку формы развитой жизни на Рюге, судя по освещённой стороне, отсутствуют, то наблюдать панораму освещённых неоном ночных городов на ночной стороне Рюги не "светит".

Скорее всего вместо Рюги можно будет увидеть только "непроглядную тьму".

Принципиально всё меняется. У Луны скорость вращения вокруг своей оси синхронизирована со скоростью вращения вокруг Земли, поэтому мы всегда видим одну сторону Луны. У Рюгу эти скорости вращения не совпадают, поэтому постоянно затененной стороны нет. В тени все время находятся разные участки поверхности.

Проверил, на всякий случай, по более свежим сообщениям http://www.hayabusa2.jaxa.jp/topics/20180625je/index_e.html - First of all,
the rotation axis of the asteroid is perpendicular to the orbit

Что в переводе от Гугля означает (абзац побольше захватил): 
Прежде всего, ось вращения астероида перпендикулярна орбите.
Этот факт увеличивает степень свободы при посадке и отличные операции.
С другой стороны, есть пик в окрестности экватора и ряд крупных кратеров, что делает выбор посадочных мест интересным и сложным. 

Ещё деталь: крайне низкое альбедо 0,05 - возможно, для подготовки качественных снимков это имеет значение и японцы "берегут" изображения других интересных участков поверхности для последующих публикаций

brianmayforreal (https://www.instagram.com/brianmayforreal/) RYUGU UPDATE ! Yep - at first sight this looks a lot like the last one. It this is different - fr om the latest images released by Hayabusa2. These are taken 25 minutes apart (as opposed to 13 last time), so the stereo is very 'hyper' - i.e. very exaggerated - to the point wh ere it's quite tricky to view. So good luck ! It it's worth the effort because it reveals a lot more fascinating detail on the surface of Ryugu. Many thanks to the JAXA team for this amazing material ! Enjoy ! Bri

ЦитатаStereo image of asteroid Ryugu by Dr Brian May

Brian May, the lead guitarist from the British rock band, Queen, has created a stereoscopic image of Ryugu from photographs captured with the ONC-T camera onboard Hayabusa2, so that the asteroid can be viewed in three dimensions. Brian May is an astronomer, with a doctoral degree in astrophysics from Imperial College London. He has a strong interest in planetary defense or space guard, which considers the potential threat to the Earth from meteorites. As part of this, May is a core member of "Asteroid Day" (https://asteroidday.org/), that began about three years ago to increase awareness of asteroids and action that can be taken to protect the Earth.
Held on June 30th each year, Asteroid Day draws attention to the risk of collisions from celestial bodies on the Earth. The day marks the anniversary of the Tunguska explosion in Russia that occurred on June 30, 1908 due to an incoming meteroid. Within Japan, the Japan Spaceguard Association and member of JAXA are also involved in Asteroid Day. In particular, the two asteroids explored by the Hayabusa and Hayabusa2 missions, Itokawa and Ryugu, both have orbits that approach the Earth, and data from these missions is also being used to better understand planetary defense.

Brian May has previously created images to sterescopically view celestial bodies, and approached the Hayabusa2 Project to propose a stereoscopic image of Ryugu. May corresponded with Dr Patrick Michel from the Côte d'Azur Observatory, France and member of the Hayabusa2 Project (the two scientists are seen in Figure 1). According to Michel, Brain May was very pleased when he received the images of asteroid Ryugu from the Hayabusa2 team as the stereo image could then be created very quickly.

With these images, Brian May created the stereoscopic image pair of Ryugu, revealing the asteroid in three dimensions for the first time (Figure 2). If you can manage the stereoscopic vision, you can see not only the whole form of Ryugu but also the irregularities of the surface.

If it is hard to see in stereoscopic vision from Figure 2, how about Figure 3 below? This figure was created by Yoshiro Yamada, who superimposed the two images made by Brian May in red and blue. Using red-blue stereo glasses (right eye should be blue, the left should be red) the image should then appear in three-dimensions.

We think that being able to see Ryugu in three dimensions makes the asteroid appear even more interesting. At the Hayabusa2 Project, we are about to conduct a variety of different analyses of Ryugu, including creating a three-dimensional model of the asteroid in the near future.

MASCOT asteroid lander
    [/li]
  • First signals received from asteroid lander MASCOT upon its arrival at asteroid Ryugu
  • Start of period of intensive landing preparations
  • Cooperation between Germany, France and Japan
  • Focus: Aerospace, exploration, robotics
On 6 July 2018 at 03:15 CEST (01:15 UTC), it was time. The team at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) MASCOT Control Center in Cologne received the first signals from the German-French asteroid lander MASCOT (https://www.dlr.de/dlr/en/desktopdefault.aspx/tabid-10975/) upon its arrival at the near-Earth asteroid Ryugu (https://www.dlr.de/dlr/en/desktopdefault.aspx/tabid-10975/1755_read-28629/#/gallery/31190). On 27 June 2018, the lander reached the asteroid aboard the Japanese space probe Hayabusa2 after a three-and-a-half year journey through space. For the first time this year, the researchers have contact with MASCOT and are presently checking all the on-board systems and instruments. "Now begins the period of intensive landing preparations, because we can only intervene to a limited extent during the landing," says MASCOT Ground Segment and Operations Manager Christian Krause from the DLR Microgravity User Support Center (https://www.dlr.de/rb/en/desktopdefault.aspx/tabid-9342/) (MUSC).

MASCOT will only be accessible from Earth for a limited number of time windows when landing on Ryugu, with commands to the lander and a response back to Earth taking more than 30 minutes. During the approximately 16-hour-long measurement operation on the surface, MASCOT has to be largely left to its own devices, and the landing exercises and tests on the ground are therefore of particular importance. "We have subjected all of the landing sequences to extensive testing using a ground model of MASCOT," explains Krause. "With the model we can, for example, test the system sequences during movement and realignment, as well as examine the scientific processes of the experiments on board." Since the launch of Hayabusa2 (https://www.dlr.de/dlr/en/desktopdefault.aspx/tabid-10080/150_read-12372/#/gallery/17357) and MASCOT on 3 December 2014, the researchers have, together with JAXA, been working through and refining the landing sequences and instrument calibrations with the ground model. For the most part, they have had to work without much information about the asteroid and make broad assumptions about the surface conditions and reflectivitywhich they can now adapt and refine.

A leap into the unknown
"Our goal is to collect as much data as possible during the landing and the measurement phase. To do this, we must prepare the processes as robustly as possible for the inhospitable and unpredictable environment on the asteroid surface," says MASCOT Project Manager Tra-Mi Ho from the DLR Institute of Space Systems (https://www.dlr.de/irs/en/desktopdefault.aspx). Four instruments are installed inside the 30 × 30 × 20 centimetre lander, which weighs only 10 kilograms. The mineralogical and geological composition of the asteroid surface will be investigated and the surface temperature and magnetic field of the asteroid determined by means of a radiometer and a camera from DLR, a spectrometer from the Institut d'Astrophysique Spatiale (https://www.ias.u-psud.fr/en) and a magnetometer from TU Braunschweig (http://www.igep.tu-bs.de/forschung/weltraumphysik/projekte/mascot/index_en.php). MASCOT will receive the necessary kinetic energy for its 'jumping' manoeuvres on the surface via a built-in swing arm. "The instruments and systems will now undergo another health check (https://www.dlr.de/dlr/en/desktopdefault.aspx/tabid-10081/151_read-18664/#/gallery/23720) upon arrival, as they have done each year during the trip to Ryugu," explains Tra-Mi Ho.

The landing site selection for MASCOT is planned for mid-August together with the partners from the French space agency CNES (https://cnes.fr/en) and the Japanese space agency JAXA (http://global.jaxa.jp/). "Then it will be very exciting for us at the MASCOT Center before landing, when we refine the landing procedures with the last details," says Christian Krause. "However, even if we know the landing site we have to be prepared for many eventualities, because MASCOT's movement on the surface after the first contact is unpredictable. It is conceivable that MASCOT will come to rest after the first contact with Ryugu." Here the research team uses the flight dynamics calculations of the French colleagues of the CNES, in order to be able to estimate the range of action of MASCOT as accurately as possible. This is also important for the pre-programmed 'jumps' of up to 70 metres in order to perform measurements at various points on the asteroid surface.
About the Hayabusa2 mission and MASCOT
Hayabusa2 is a Japanese space agency (Japan Aerospace Exploration Agency; JAXA) mission to the near-Earth asteroid Ryugu. The German-French lander MASCOT on board Hayabusa2 was developed by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and built in close cooperation with the French space agency (Centre National d'Etudes Spatiales; CNES). DLR, the Institut d'Astrophysique Spatiale and Technical of University Braunschweig have contributed the scientific experiments on board MASCOT. The MASCOT lander and its experiments are operated and controlled by DLR with support from CNES and in constant interaction with the Hayabusa2 team.

The DLR Institute of Space Systems in Bremen was responsible for developing and testing the lander together with CNES. The DLR Institute of Composite Structures and Adaptronics in Braunschweig was responsible for the stable structure of the lander. The DLR Robotics and Mechatronics Center in Oberpfaffenhofen developed the swing arm that allows MASCOT to hop on the asteroid. The DLR Institute of Planetary Research in Berlin contributed the MasCam camera and the MARA radiometer. The asteroid lander is monitored and operated from the MASCOT Control Center in the Microgravity User Support Center (MUSC) at the DLR site in Cologne.

形状モデルチームでは、同じ画像データから、二つの異なった方法で形状モデルを作成しています。一つ目の方法は、Structure-from-Motion(SfM)と呼ばれるステレオ視の手法の一種です。最近よく見かける、ドローンからの空撮の映像から地形や建物の形を作成するのにも用いられています。図1に示されているモデルがこの方法で作成されたものです。もう一つの方法は、Stereophotoclinometry (SPC)と呼ばれるもので、「はやぶさ」探査機が訪問した小惑星イトカワの形状を調べるのにも用いられました。図2に示されているモデルがこの方法で作成されたものです。二つの形状モデルデータを比較することで、リュウグウの形状をどの程度の精度で計測できているかを把握することができます。それぞれ細かい差異はありますが、どちらもそろばんの珠のようなリュウグウの全体形状や、その表面にあるクレーターのような窪地、岩塊が再現できていることがわかります。
(Команда исследователей формирует модели формы из одних и тех же данных изображения двумя различными способами. Первый метод - это тип стереовидения, называемый Structure - from - Motion (SfM). Он используется для создания топографии и построения фигур из фотоизображений с космического аппарата, которые мы видели недавно. Таким образом была создана модель, показанная на рисунке 1. Другой метод, называемый Stereophotoclinometry (SPC), уже использовался для исследования формы астероида Итокава, посещенного зондом Хаябуса. Таким образом была создана модель, показанная на рисунке 2. Сравнивая данные двух геометрических моделей, мы можем понять степень точности измерения формы Рюгю. Хотя есть незначительные различия, можно увидеть, что вся форма Рюгю похожа на шарик на счётах и все кратерные депрессии и массивы горных пород на поверхности могут быть воспроизведены.)

Animation of the stereoscopic global image of asteroid Ryugu. When viewed through red / blue glasses (blue filter over the right eye), the asteroid should look three-dimensional. The images were captured with the Optical Navigation Camera - Telescopic (ONC-T), photographed on June 23, 2018.

These animations show the result of sequential images of asteroid Ryugu taken with the ONC-T (Optical Navigation Camera - Telescopic) during the final approach to Ryugu on June 23, 2018. Images were captured at approximately 10 degrees increments as the asteroid rotates. The distance fr om the spacecraft to Ryugu at this time was about 40 km.

If you assemble red-blue glasses (placing the blue filter over your right eye) and look at these figures, Ryugu should appear three dimensional. The overall shape of Ryugu and the undulations of he craters and boulders become very cler.

From here on, we will be investigating Ryugu in more detail.

ЦитатаInitial version of the shape model
for Ryugu


We previously introduced a global image of asteroid Ryugu (http://www.hayabusa2.jaxa.jp/topics/20180710je/index_e.html), but the Hayabusa2 Project shape model team have also created three-dimensional models of the asteroid. The asteroid was measured using images captured with the ONC-T (Optical Navigation Camera - Telescopic) to form a "shape model" of Ryugu. The shape of Ryugu is fundamental information when considering the formation history of the asteroid and it is also key to future operations by Hayabusa2.

The shape model team have initially used images taken during Hayabusa2's arrival at the asteroid to create the first three-dimensional shape models of Ryugu. This shape models were used in Figures 1 and 2 to show animations of the rotating Ryugu generated using computer graphics.

The shape model team created shape models fr om the same image data in two different ways. The first method shown in Figure 1 is a type of stereoscopic technique called "Structure-from-Motion" (SfM). This is the same method that is used to create terrain and building shapes from aerial images that are commonly seen when taken by a drone. Figure 2 shows the shape model created with a second method known as "stereophotoclinometry" (SPC). This technique was also used to model the shape of asteroid Itokawa, the destination of the first Hayabusa spacecraft. By comparing the two shape models, we can assess how accurately the shape of Ryugu has been replicated. Although the two models show minor differences, both depict a global shape similar to the bead on an abacus, with recesses that look like craters and boulders of rock on the surface.

If higher resolution images of Ryugu are obtained in future observations, the three-dimensional shape of the asteroid can be clarified in greater detail.

★ Hayabusa2 status(the week of 2018.7.2) ★
The first week after arriving at Ryugu has gone by in a flash. Monitoring the landscape of a brand-new astronomical object for humanity while continuing spacecraft operations is a wonderful and amazing experience.

The two main activities this week were:
・Establishing the procedure needed to accurately hover 20km above the asteroid.
・An operation check of the observational instruments when directed towards Ryugu.

The outcome of both activities was good. The LIDAR (Laser altimeter) measured the altitude of the asteroid's facing surface and the Ka-band communication equipment started sending high speed data through the NASA Deep Space Network. From the Doppler shift of the radio waves sent from Hayabusa2, we could tell that the spacecraft is feeling the gravity of the asteroid. Hayabusa2's exploration of Ryugu in this first week has been a smooth start.

★ Hayabusa2 status (the week of 2018.7.16) ★

Last week we performed short-term operations at an altitude of about 6 km. This allowed closer observations of Ryugu in more detail and the data downlink is happening now. While usual operations are "BOX-A", these operations at a different maintenance altitude are called "BOX-C" operations. While we did not keep the order, we will do "BOX-B" operations. Do look forward to these!

МОСКВА, 26 июл - РИА Новости. Зонд "Хаябуса-2" получил первые сверхчеткие фотографии поверхности астероида Рюгю, сблизившись с ним на расстояние в шесть километров. Снимки и первые результаты наблюдений были представлены на сайте JAXA (http://www.hayabusa2.jaxa.jp/topics/20180725je/index_e.html).
Автоматическая станция "Хаябуса-2" была запущена в космос в начале декабря 2014 года для изучения, забора и возврата проб с астероида Рюгю. Как надеются ученые, она вернет на землю первые 100% "чистые" пробы первичной материи Солнечной системы.
Японский аппарат достиг цели в начале июня и начал длительную процедуру торможения и сближения с астероидом. Форма астероида неоднократно "менялась" по мере сближения зонда с небесным телом и повышения качества снимков.

Сначала ученым казалось, что он был похож на идеальный шар, потом - на "пельмешек" или шарик данго, национальной японской сладости. Более поздние серии снимков и своеобразный видеоролик, полученные "Хаябусой-2" в середине июня, показали, что он имеет более угловатую форму и похож на кубик сахара или кристалл шпата.

"Хаябуса-2" официально прибыла к Рюгю в начале июля, остановившись в 20 километрах от поверхности астероида. Последующие несколько недель зонд потратил на включение и диагностику научных инструментов, а также на изучение формы и физических свойств Рюгю.

Набрав достаточное количество данных, пилоты миссии продолжили сближение с астероидом, в результате чего "Хаябуса-2" временно перешла на новую, гораздо более тесную орбиту. Через некоторое время зонд включил двигатели и вернулся на прежнюю позицию, безопасную для его работы.
В момент максимального сближения зонд и Рюгю разделяло всего шесть километров пустоты, что позволило ученым повысить четкость снимков примерно в 3,4 раза и рассмотреть новые детали его рельефа. К примеру, оказалось, что поверхность астероида покрыта необычно большим числом крупных "булыжников", чье происхождение пока остается загадкой для планетологов.

Забор грунта, несмотря на то, что "Хаябуса-2" уже достигла Рюгю, произойдет совсем нескоро. Сначала зонд должен определить свою точную орбиту и скорректировать ее, если возникнет такая необходимость, а затем -- всесторонне изучить структуру недр и рельеф астероида.

Только после этого межпланетная станция сблизится с поверхностью Рюгю и сбросит на нее своеобразный "взрывпакет", который обнажит и выбросит нетронутый материал из недр астероида. "Хаябуса-2" соберет эту пыль и гальку, левитирующую в вакууме, во время второго пролета над этой точкой.

Ryugu - a 'diamond' in space

Цитата
    [/li]
  • Asteroid Ryugu was imaged for the first time fr om a distance of just six kilometres
  • Among other things, the images serve as preparation for the landing site selection. The MASCOT lander, which was developed and built at DLR, is due to land on the asteroid in October.
  • Focus: Space, Exploration
As the Japanese Hayabusa2 spacecraft closes in on asteroid Ryugu, more details become visible to the planetary scientists. On 20 July 2018, from a distance of just six kilometres, the spacecraft's Optical Navigation Camera - Telescopic (ONC-T) acquired an image of the asteroid's surface, with its largest crater. "We see that the entire surface of Ryugu is strewn with large boulders - we have not yet seen this on an asteroid," says Ralf Jaumann, a planetary scientist at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and Principal Investigator for the MASCOT (Mobile Asteroid Surface Scout) (https://www.dlr.de/dlr/en/desktopdefault.aspx/tabid-10975/) lander aboard the Japanese spacecraft. It is anticipated that on 3 October 2018, MASCOT will land on Ryugu and examine the asteroid surface using four instruments.

Descending towards the asteroid
Since Hayabusa2's arrival at the asteroid on 27 June 2018, the Japanese Aerospace Exploration Agency (JAXA) (http://global.jaxa.jp/) had operated it at a height of 20 kilometres (the Home Position) above the surface. But on 16 July, the JAXA engineers slowly lowered Hayabusa2 from this observation position, until it was six kilometres above Ryugu. The resolution of the images is approximately 3.4 times greater than in the pictures acquired from the Home Position - one pixel now corresponds to about 60 centimetres. A particularly large crater is visible near the centre of the image.
For Jaumann, the images coming from some 300 million kilometers away give the opportunity to get a first impression of the asteroid: "It is likely that Ryugu is a fragment of an earlier collision. However, we have only just been at the asteroid for a short while - and all we can see is the surface." How old is the asteroid? What is its interior like? How dense is it? Is it made up of several agglomerated pieces of debris or is it just one large piece? These are all questions that the planetary scientists want to discuss and answer.
Preparations for the landing
On 25 July 2018, the Hayabusa2 probe returned to its previous position 20 kilometers from Ryugu. In August 2018, the probe will then be lowered again to a distance of approximately one kilometre from the asteroid's surface to measure its gravitational field, which is estimated to be just 1/60,000th of Earth's. The detailed photographs of the 900-metre-diameter Ryugu and the determination of its gravitational field are also important for the selection of MASCOT's landing site. At the end of August, the site will be determined by all involved international scientists and engineers. During the mission, Hayabusa2 will also descend to the asteroid's surface several times and collect soil samples. At the end of 2019, the Japanese probe will begin its return journey to Earth, wh ere it is expected to arrive in 2020 with the asteroid samples.

★ Hayabusa2 status(the week of 2018.7.23)★

This week, we returned from the 6km altitude "BOX-C" to "BOX-A", staying at an altitude of 20km±1km while images taken at BOX-C were downloaded. The images released on July 25 showed a detailed view of the unevenness of Ryugu's surface. Meanwhile, we conducted a test on the laser distance measurer, LIDAR, in preparation for the "Middle Altitude Observation Operation", in which the spacecraft will descend to hover at a 5km altitude and then perform the "Gravity Measurement Descent Operation" which decreases the altitude to just 1km. We are ready!

ЦитатаA spectroscopic image of Ryugu at high resolution

The article posted on July 25, 2018 (http://www.hayabusa2.jaxa.jp/topics/20180725je/index_e.html) introduced an image captured when Hayabusa2 descended towards asteroid Ryugu, reaching an altitude of just 6km above the surface. At this time, we also took photographs in which the viewing angle towards the asteroid gradually changed as Ryugu rotated. Using the previously published image and a second image fr om a slightly different angle (see the referlence at the end of this page), we created a composite frame where the two photographs are superimposed in red and blue (Figure 1). If you view this image with red-blue stereoscopic glasses (right eye should be blue, left eye is red), you can see this high resolution image of the asteroid in three-dimensions and explore the shape and topography of this small world.

Figure 1: A red and blue stereoscopic image of Ryugu, prepared from the images taken by the Optical Navigation Camera - Telescopic (ONC-T) at an altitude of 6km. The images were taken on July 20, 2018. 
Image credit ※:JAXA, University of Aizu, University of Tokyo, Kochi University, Rikkyo University, Nagoya University, Chiba Institute of Technology, Meiji University and AIST.
Comparing this new image with the stereoscopic image we previously introduced (part 1 (http://www.hayabusa2.jaxa.jp/topics/20180704je/index_e.html), part 2 (http://www.hayabusa2.jaxa.jp/topics/20180710je/index_e.html)), the three-dimensional view is much more powerful with the irregularities on the surface significantly more emphasized. This is due to the high resolution of the composite photographs which were taken closer to the asteroid, and because the difference in the angle at which each image sees the asteroid is larger than that difference would be between the view from your left and right eye. While it depends on exactly how each person sees the stereo image, do be careful that the features may be exaggerated compared to the actual shape of Ryugu and the contours of the terrain.

Different types of topography can be spotted, such as the overhang along the equator of Ryugu in the center of the image and the unevenness created by the variety of large and small boulders as well as the circular dents of craters.

From the images in Figure 1, Dr. Brian May made a second binocular stereo image of Ryugu (the first binocular stereo image is here (http://www.hayabusa2.jaxa.jp/topics/20180704je/index_e.html)). Dr. May tweeted regarding the new image (Figure 2), which we show in Figure 3.

[MAltOp] While operating the ion engines, Ryugu was only a point, even when using the telephoto camera --explains IES兄-- the asteroid seems so big in the wide-angle camera now. From 2.9 billion km to 5km. If seems like you could touch it if you stretched out your hand.

ЦитатаЯпонские ученые пока не смогли обнаружить признаки наличия воды на астероиде Рюгу

Космос (http://tass.ru/kosmos) | 4 августа, 13:43 UTC+3

ТОКИО, 4 августа. /Корр. ТАСС Алексей Заврачаев/. Японские ученые пока не смогли обнаружить признаки наличия воды на астероиде Рюгу, который находится в 280 млн км от Земли. Об этом сообщило Японское агентство аэрокосмических исследований (JAXA).

С конца июня благодаря подошедшему на очень близкое расстояние зонду "Хаябуса-2" ("Сокол-2" ) ученым удалось визуально изучить порядка 54 тыс. точек на поверхности космического тела. Однако, никаких следов влаги им найти так и не удалось. При этом неизвестно, всегда ли он был лишен воды, или это произошло в какой-то из периодов его существования.

Рюгу относится к классу C - самому распространенному из ныне изученных. Это означает, что в них присутствует большое количество углерода. Также, согласно статистике, на глыбах на поверхности таких тел можно зачастую обнаружить частички воды.

Поэтому японские ученые не оставляют надежд добиться желаемого результата и в процессе исследования Рюгу. В частности, в JAXA не исключают, что жидкость может проявится в процессе создания искусственного кратера, намеченного на весну следующего года.

Если никаких препятствий не возникнет, то уже в сентябре или октябре "Хаябуса-2" совершит первую попытку посадки на Рюгу, чтобы взять образцы пород. Всего таких попыток будет три, а на Землю аппарат должен вернуться в конце 2020 года.
Диаметр Рюгу, который находится между Землей и Марсом, около 900 м. "Хаябуса-2" был запущен к астероиду в декабре 2014 года с космодрома на японском острове Танэгасима. Ученые надеются найти на астероиде следы воды и органических веществ, что может помочь в разгадке тайны распространения жизни во Вселенной.

"Хаябуса-2" весит около 600 кг. Он представляет собой модифицированную версию первого "Сокола", который впервые в истории сумел доставить на Землю образцы материалов, собранные на поверхности иного, нежели Луна, космического объекта. В мае 2003 года он отправился к удаленному от Земли на 336,5 млн км астероиду Итокава. За семь лет зонд проделал самое продолжительное в истории человечества путешествие длиной 6 млрд км.

★ Hayabusa2 status(the week of 2018.7.30)★

From our descent through BOX-C to an altitude of about 6km last week, we made a fleeting return to BOX-A at a 20km altitude. Then this week, we conducted the "Medium Altitude Observation" operation, which is the first critical operation after arrival. Unlike BOX-C, we descended to an altitude of about 5km in 24 hours while performing strict position control, then hovered at the same altitude for 1 asteroid rotation cycle while observing the asteroid. As the first critical operation, it was a tense period but the operation safely succeeded and I think gave momentum for future operations. Next week, we will implement the "Gravity Measurement Operation" which is a second critical operation.

ЦитатаRyugu at an altitude of 1 km

Hayabusa2 arrived at asteroid Ryugu on June 27. On July 20 - 21, the spacecraft descended to an altitude of about 6 km for BOX-C operations. On August 1, we descended again in a Medium Altitude Operation that took Hayabusa2 to a 5 km altitude. Then fr om August 6, we performed the third descent operation to measure the gravity of Ryugu.

In the gravity measurement operation, we allow the spacecraft's motion to be determined by the attraction of Ryugu's gravity without controlling the trajectory and attitude of the spacecraft ("free-fall" and "free-rise" ). By monitoring the exact movement of the Hayabusa2, we can see how strong the gravitational attraction is from Ryugu.

The spacecraft began the descent from the home position (at a 20km altitude from Ryugu) on August 6, before 11:00 JST. At about 20:30 JST on the same day, the altitude had dropped to 6000 m. From there, we began our free-fall. Hayabusa2 approached a minimum altitude of 851 m on August 7 at about 08:10 JST. From there, the thrusters were fired and the spacecraft began to rise.
Figures 1 and 2 show the images taken with the Optical Navigation Camera - Telescopic (ONC-T) just before reaching the minimum altitude.

МОСКВА, 8 авг - РИА Новости. Зонд "Хаябуса-2" получил фотографии астероида Рюгю с высоты в 930 метров от его поверхности и "пощупал" структуру его гравитационного поля. Снимки и данные были опубликованы на сайте JAXA (http://www.hayabusa2.jaxa.jp/en/topics/20180807e/index.html).
Автоматическая станция "Хаябуса-2" была запущена в космос в начале декабря 2014 года для изучения, забора и возврата проб с астероида Рюгю. Как надеются ученые, она вернет на землю первые 100% "чистые" пробы первичной материи Солнечной системы.
Японский аппарат достиг цели в начале июня и начал длительную процедуру торможения и сближения с астероидом. Форма астероида неоднократно "менялась" по мере сближения зонда с небесным телом и повышения качества снимков.

Сначала ученым казалось, что он был похож на идеальный шар, потом - на "пельмешек" или шарик данго, национальной японской сладости. Более поздние серии снимков и своеобразный видеоролик, полученные "Хаябусой-2" в середине июня, показали, что он имеет более угловатую форму и похож на кубик сахара или кристалл шпата.

"Хаябуса-2" официально прибыла к Рюгю в начале июля, остановившись в 20 километрах от поверхности астероида. Последующие несколько недель зонд потратил на включение и диагностику научных инструментов, а также на изучение формы и физических свойств Рюгю.

На прошлой неделе зонд провел серию маневров, которые сначала вывели его на высоту в 6 километров от поверхности Рюгю, а затем заставили его опуститься еще ниже, что было необходимо для замеров силы гравитационного поля астероида.

Вчера, как отмечает JAXA, "Хаябуса-2" совершила "нырок" в сторону астероида, сблизившись с ним на расстояние в 851 метр до того, как зонд включил двигатели и вернулся на прежнюю орбиту. Благодаря этому его камеры смогли получить фотографии с рекордно высоким разрешением, примерно 50 сантиметров на пиксель.

Данные, собранные в ходе этого "нырка" и возврата на прежнюю орбиту, помогут ученым понять, как устроено гравитационное поле Рюгю и как сильно он притягивает "Хаябусу" и другие окружающие объекты. Его изучение, как отмечают японские планетологи, поможет нам понять, как устроены недра астероида и есть ли в нем крупные пустоты.

ЦитатаHayabusa 2 probe gets a closer look at asteroid amid landing preps
August 15, 2018 (https://spaceflightnow.com/2018/08/) | Stephen Clark (https://spaceflightnow.com/author/stephen-clark/)

The Japanese Hayabusa 2 spacecraft dropped within a half-mile of asteroid Ryugu last week, probing its gravity field ahead of key decisions in the coming days to settle on a target site for the robotic mission's first sample collection attempt, and the best touchdown location for a European lander stowed on the mothership.

The descent to a distance of 2,792 feet (851 meters) fr om Ryugu was the closest Hayabusa 2 has come to the asteroid since arriving at a stationkeeping position roughly 12 miles (20 kilometers) fr om the object June 27.

During the descent last week, ground controllers commanded Hayabusa 2 to disable its rocket control thrusters, allowing sensors on the spacecraft to measure the probe's attraction to Ryugu by the asteroid's gravitational field. Once it reached the point of closest approach Aug. 6, Hayabusa 2 fired jets to climb away fr om Ryugu, and the spacecraft again collected data on the asteroid's gravity.
"In the gravity measurement operation, we allow the spacecraft's motion to be determined by the attraction of Ryugu's gravity without controlling the trajectory and attitude of the spacecraft ("free-fall" and "free-rise")," officials wrote in an upd ate on Hayabusa 2's official website. "By monitoring the exact movement of the Hayabusa 2, we can see how strong the gravitational attraction is fr om Ryugu."

The data will help navigators at the Japan Aerospace Exploration Agency's control center in Sagamihara, on the outskirts of Tokyo, plot future movements of Hayabusa 2 around the asteroid. Improved gravity measurements should also help engineers develop more accurate trajectories when the mission descends to Ryugu's surface later this year for the first of three touch-and-go landings to snag rock specimens for return to Earth.

Close-up imagery recorded by Hayabusa 2's telescopic optical camera revealed new details about Ryugu's surface last week, showing textures, rugged ridges and large boulders strewn across a dark gray landscape.

Scientists are expected to soon decide wh ere to send Hayabusa 2 this fall to gather its first sample. Researchers are meeting this week in Sagamihara to assess the mission's early data returns.

Hayabusa 2 is a follow-up to Japan's Hayabusa mission, which explored asteroid Itokawa in 2005 and returned microscopic samples to Earth in 2010. Hayabusa encountered numerous problems that threatened to end the mission, including a fuel leak and a malfunction in its sampling mechanism, which caused it to collect much less sample material than originally planned.

Japan's new asteroid mission incorporated several upgrades from Hayabusa, and it launched in December 2014 to kick off the three-and-a-half-year trip to Ryugu.

Mission managers this week are also discussing wh ere a European lander riding piggyback on Hayabusa 2 should land on Ryugu.

The Mobile Surface Asteroid Scout, or MASCOT, is a tiny addition to the Hayabusa 2 mission. Developed by the German and French space agencies -- DLR and CNES -- the battery-powered lander measures 12 inches by 12 inches by 8 inches (30 x 30 x 20 centimeters), and it weighs just 22 pounds (10 kilograms).

In early October, Hayabusa 2 will spring-eject the MASCOT spacecraft, aiming it toward a predetermined site on Ryugu for a slow-speed crash landing. Assuming the landing goes according to plan, MASCOT will power up its four instruments, including a camera, to survey the asteroid, then activate a swing arm to catapult to another part of Ryugu for more observations.

The asteroid spans around 3,000 feet (900 meters) in diameter, and takes around 7.6 hours to complete one rotation. Ryugu's orbit loops it around the sun once every 1.3 years.

The diminutive size of Ryugu translates to a tenuous gravity field estimated to be 60,000 times weaker than Earth's, meaning a relatively minor push could propel an object long distances across the asteroid, or even back into space.

Ryugu is a C-type asteroid, and scientists believe it contains primitive building blocks left over the formation of the solar system 4.5 billion years ago.

Ralf Jaumann from the DLR Institute of Planetary Research, principal investigator on MASCOT, says he is excited about the lander's exploration of Ryugu.

"In all honesty, I have seen lots of asteroids before, but nothing quite like this," Jaumann said in an interview posted on DLR's website. "The many large boulders on the surface are extremely interesting! This is something that has never been seen. The Itokawa asteroid that was visited by the first Hayabusa mission also features boulders, but not as large or as homogenously distributed.

"Ryugu also has more impact craters than other small asteroids," adds Jaumann, who also works as a scientist on NASA's Dawn mission to Ceres, the largest object in the asteroid belt.

"But what is really impressive are the numerous, very large boulders on the surface," Jaumann said. "This material appears to be much stronger than the fine material that we see. I am really looking forward to the lander being on the surface and being able to view such a boulder up close."

Officials charged with selecting MASCOT's landing site have ruled out the asteroid's poles. Engineers also want to keep MASCOT away from a region wh ere long periods of sunlight could cause it to overheat.

Hayabusa 2's recent gravity measurement will feed into the decision on wh ere to send MASCOT.

"Gravity will affect how MASCOT bounces and this will influence the final position at which the released lander comes to rest," said Tra-Mi Ho, MASCOT project leader at DLR's Institute of Space Systems. "Information on the asteroid's thermal characteristics is also crucial. That is still lacking and is being examined at the moment. Another important aspect is the size of the rocks on Ryugu. A certain size of rock could cause MASCOT to get stuck."

Despite the risk from Ryugu's boulders, officials were heartened to discover the asteroid does not have the unusual dual-lobe potato shape of comet 67P/Churyumov-Gerasimenko, the destination wh ere Europe's Rosetta spacecraft explored for more than two years, and deployed a lander named Philae.

Philae and MASCOT were developed by many of the same engineers and scientists in Germany and France, but MASCOT is the smaller of the two. The lander set to arrive at Ryugu is designed to function for 16 hours -- it can't recharge with solar power -- and will relay images and other data to Earth through the Hayabusa 2 mothership

"Ultimately, I was relieved that it was not a celestial body like the comet 67P/Churyumov-Gerasimenko, on which Philae landed in November 2014," Ho said. "At least Ryugu is more consistently formed than 67P. Of course, we had qualms on seeing all those rocks - together with concerns about whether it would all be too challenging for MASCOT."

Hayabusa 2 carries more deployable landers developed by Japanese scientists for placement on the surface of Ryugu over the next year-and-a-half.

The mission is se t to depart the asteroid in late 2019, with return to Earth scheduled for December 2020 with a parachute-assisted landing of Hayabusa 2's sample carrier in Australia.

★ Hayabusa2 status(the week of 2018.8.6)★

From August 5 - 7 this week we performed the "Gravity Measurement Descent" operation. This was the second operation in which Hayabusa2 descended towards the asteroid using the same technique as for landing. The final altitude was 851m! At this close approach, the gravity of Ryugu could be sufficiently felt to be measured and we were able to take valuable close-up images. Now at ISAS, researchers are gathering from Japan and abroad. Sagamihara is passionate about the scientific debate on this brand-new astronomical object for humanity.

【Операция измерения гравитации】 7 августа 2018 года 12: 30 (время в Японии): космический корабль неуклонно поднимается и высота составляет около 3 км. Восходящая скорость составляет около 12 см в секунду. Он не контролирует траекторию, это свободное восходящее состояние, противоположное свободному падению. Для того, чтобы уравновесить гравитационную силу астероида Рюгуу, скорость подьёма постепенно уменьшается.

Hayabusa-2 прибыл на астероид Ryugu 27 июня. 20-21 июля космический корабль спустился на высоту около 6 км для проведения операций BOX-C. 1 августа его снова подвергли  операции (вывода на) средней высоты, которая переместила Hayabusa-2 на 5-километровую высоту над поверхностью астероида. Затем, 6 августа,  провели третью операцию спуска, чтобы измерить гравитацию Рюгу.
В операции измерения силы тяжести мы допускаем, чтобы движение космического корабля определялось притяжением гравитации Рюгу, не контролируя траекторию космического корабля («свободный пад» и «свободный рост»). Наблюдая за точным движением Hayabusa-2, мы можем видеть, насколько сильным является гравитационное притяжение от Ryugu.
Космический корабль начал спуск с домашнего положения (на высоте 20 км от Рюгу) 6 августа, до 11:00 JST. Примерно в 20:30 JST в тот же день высота снизилась до 6 км. Оттуда мы начали наше свободное падение. Hayabusa2 приблизился к минимальной высоте 851 м 7 августа примерно в 08:10 JST. Оттуда были запущены двигатели, и космический корабль начал подниматься.

По мере того, как Hayabusa-2 начал подниматься, орбита и контроль ориентации не выполнялись до тех пор, пока космический корабль не достиг высоты около 5 kм. Данные параметров движения Хаябусы-2 за это время также будут использованы для оценки тяжести Рюгу.

★ Hayabusa2 status(the week of 2018.8.13)★

After returning from the Gravity Measurement Operation, Hayabusa2 operated in BOX-A (the home position). Japan experienced very unsettled weather this week, with thunderstorm around the Usuda Deep Space Centre. In addition to this, thunderstorm occurred at US Goldstone ground station when we operated Hayabusa2 from there. Weather at the ground stations is concerning. Also this week was an active discussion on landing locations. On August 17, a large number of international Project Members gathered to engage in this debate. From August 18, BOX-B operations began and the spacecraft starting moving from BOX-A.

Посадка на астероид планируется!
ЦитатаПосле прибытия к цели в июне-июле 2018 г. «Хаябуса-2» произведет с высоты около 20 км обследование поверхности Рюгу с использованием различных инструментов дистанционного зондирования. После выбора подходящего района зонд снизится до высоты 100 метров, откуда будет спущен небольшой европейский посадочный зонд MASCOT (Mobile Asteroid Surface Scout) и три японских прыгающих аппарата-ровера Minerva 2.
Заборы грунта с «первородной» поверхности и из искусственно созданного с помощью ударника кратера должны состояться в первой половине 2019 г. А в ноябре или декабре «Хаябуса-2» покинет астероид и отправится в обратный путь; прибытие к Земле ожидается через год - в декабре 2020 г.

Ученые выбрали места посадок на астероид Рюгу в рамках миссии «Хаябуса-2»
(https://s.hi-news.ru/wp-content/uploads/2018/08/mascot_landing-650x366.jpg)
Японское агентство аэрокосмических исследований (JAXA) объявило об окончательном выборе посадочных мест на астероид в рамках миссии «Хаябуса-2». Напомним, что на борту основного аппарата находятся четыре спускаемых модуля: три аппарата MINERVA-II, а также посадочный модуль MASCOT, разработанный Германским авиационно-космическим центром (DLR). Основная задача запущенного в декабре 2014 года исследовательского зонда «Хаябуса-2» заключается в сборе и доставке на Землю образцов грунта с 900-метрового астероида Рюгу.

По мнению исследователей, в грунте Рюгу может содержаться вода и органические молекулы - строительные блоки, породившие жизнь на нашей планете. Японский космический аппарат достиг цели своего исследования в конце июня, после чего начал длительную процедуру торможения и сближения с астероидом. В настоящий момент «Хаябуса-2» находится на орбите всего в нескольких километрах от поверхности космического тела.

Сбор образцов грунта астероида будет производиться не с помощью посадочного модуля и роверов, а с помощью самого зонда «Хаябуса-2», непосредственно с орбиты Рюгу. Аппарат оснащен взрывным зарядом, которым он выстрелит в поверхность объекта. Взрыв поднимет в космос частицы грунта астероида. Если все пройдет удачно, астрономы ожидают, что зонд вернет образцы на Землю к концу 2020 года, сбросив их внутри специальной капсулы.

Для выбора наиболее подходящего места посадки посадочного модуля MASCOT агентство JAXA собрало целую конференцию. Астрономы выбрали десять мест-кандидатов, на которые мог бы высадиться MASCOT. В качестве основного варианта была выбрана область MA-9, расположенная в южном полушарии Рюго.

«Выбор места для посадки оказался очень тяжелой задачей. С другой стороны, теперь мы можем сказать, что мы нашли идеальное место. Эта точка, MA-9, была главным кандидатом на победу в конкурсе с самого его начала», -- заявил Ральф Яуманн из Германского авиационно-космического центра (DLR), руководитель проекта MASCOT.

Здесь имеются «почти земные» условия - температура днем и ночью варьируется от 47 до -63 градусов Цельсия, что позволит значительно продлить жизнь батареям модуля. Кроме того, ученые не обнаружили здесь никаких областей, где постоянно царит тень или свет. Горький опыт с посадочным модулем «Филы» при посадке на поверхность кометы Чурюмова-Герасименко заставил астрономов более основательно подойти к выбору нужного места.

С научной точки зрения, зона MA-9 интересна для планетологов тем, что здесь находится большое количество крупных и мелких камней, удобных для химического анализа, а также несколько областей, обнаженных относительно недавно и еще не подвергавшихся действию космических лучей и солнечного ветра.

MASCOT оснащен спектрометром, магнитометром, радиометром, а также камерой для сбора научных данных. Кроме того, аппарат имеет двигатель со смещенным центром тяжести, вращение которого позволит зонду прыгать по поверхности астероида.

Помимо места посадки модуля MASCOT агентство JAXA определилось с местом посадки роверов MINERVA-II, а также местом, где будет производиться забор грунта с помощью зонда «Хаябуса-2». Зонд должен будет сблизиться с поверхностью Рюгу в локации L07, располагающейся в области экватора. В качестве резервных областей ученые выбрали точки L08 и M04, расположенные недалеко от основной. Для высадки роверов MINERVA-II ученые выбрали зону N6, что в северной части астероида.

Согласно информации JAXA, «Хаябуса-2» сблизится с астероидом для сбора образцов грунта 12 сентября. Повторное сближение запланировано на середину октября. Роверы планируется высадить 20-21 сентября. Высадка посадочного модуля MASCOT запланирована на 3 октября 2018 года. Даты высадок еще могут измениться, отмечают в агентстве.

  • Selection of the final landing site fr om 10 candidate sites completed
  • Temperature fluctuations between 47 and minus 63 degrees Celsius at the landing site
  • More fresh material and boulders up to 30 metres tall await MASCOT
  • Landing scheduled for 3 October 2018.
  • Focus: Space, exploration, mission
Not too hot and not too cold. Not too many boulders, nor too few. Easily accessible and scientifically exciting. Meeting the requirements that the Mobile Asteroid Surface Scout (MASCOT) (https://www.dlr.de/dlr/en/desktopdefault.aspx/tabid-10975/) team had for the landing site on the asteroid Ryugu was no easy task. "However, we have now decided on an almost perfect landing site," says Ralf Jaumann from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Institute of Planetary Research, who is Principal Investigator of the MASCOT landing probe and responsible for the lander's MasCam camera experiment. DLR Project Manager Tra-Mi Ho is also satisfied with the selection of the landing site: "For the operation of our lander, the chosen landing site was among the favourites from the very start." In consultation with more than 100 international and national partners, the MASCOT landing site was sel ected from 10 potential candidates, and announced on 23 August 2018. MASCOT's landing is scheduled for 3 October 2018. The locations at which the Hayabusa2 probe is expected to take soil samples have also been designated, as have the sites wh ere the three MINVERVA-II rovers will be placed on the asteroid's surface.

Located at approximately 315 degrees east and 30 degrees south, the place at which MASCOT is supposed to land on the primordial celestial body and carry out measurements on the asteroid's surface using four instruments is, at the moment, still simply called 'MA-9'. The landing site area has several advantages. Firstly, it is far enough from the regions in which Hayabusa2 will descend to the surface and take soil samples - in this way, MASCOT and Hayabusa2 will not get in each other's way as they perform their activities. Secondly, the landing site lies in Ryugu's southern hemisphere, so with the data collected by Hayabusa2 at the equator and MINERVA in the northern hemisphere, scientists will be able to gain good coverage of and investigate the 950-metre-diameter asteroid.

Numerous boulders and fresh material

Temperatures are expected to reach up to 47 degrees Celsius during the asteroid day and drop to minus 63 degrees Celsius at night. This is in line with the desired framework conditions for the operation of the instruments and for the lander's battery. In the vicinity of the landing site, there are numerous boulders up to 30 metres tall, but the really big rocks are not located in the MA-9 region. Images acquired by the optical navigation camera on the Hayabusa2 probe indicate that the landing site area probably holds fresher material that had little exposure to cosmic radiation, the particle flow of solar winds, as well as interplanetary dust - and is therefore still very primordial and in an unchanged state.

Spoilt for choice

Making a final selection from 10 potential landing sites was not easy for the scientists and engineers. After all, every team of instrument experts should be able to get the working conditions and data that it expects. For example, the MicrOmega infrared hyperspectral microscope of the Institut d'Astrophysique Spatiale (IAS) would have preferred slightly cooler temperatures during the asteroid day. The MAG magnetometer of the Technical University Braunschweig would have favoured very large boulders for its measurements. By contrast, the MasCam camera and the MARA radiometer - both instruments developed by the DLR Institute of Planetary Research - enjoy almost ideal conditions for their scientific work because they have a view of boulders on the horizon and can examine fresh asteroid material. Ultimately, the conditions that the landing site offers are very favourable for the lander and all instruments on board. "From our perspective, the sel ected landing site means that we engineers can guide MASCOT to the asteroid's surface in the safest way possible, while the scientists can use their various instruments in the best possible way," says Tra-Mi Ho, Project Manager at the DLR Institute of Space Systems. "But we are also aware: there seem to be large boulders across most of Ryugu's surface, and barely surfaces with flat regolith. Although scientifically very interesting, this is also a challenge for a small lander and for sampling."

About the Hayabusa2 mission and MASCOT

Hayabusa2 is a Japanese space agency (http://global.jaxa.jp/) (Japan Aerospace Exploration Agency; JAXA) mission to the near-Earth asteroid Ryugu. The German-French lander MASCOT on board Hayabusa2 was developed by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and built in close cooperation with the French space agency CNES (https://cnes.fr/en) (Centre National d'Etudes Spatiales). DLR, the Institut d'Astrophysique Spatiale (https://www.ias.u-psud.fr/en) and the Technical University of Braunschweig (https://www.tu-braunschweig.de/) have contributed the scientific experiments on board MASCOT. The MASCOT lander and its experiments are operated and controlled by DLR with support fr om CNES and in constant interaction with the Hayabusa2 team.

The DLR Institute of Space Systems (https://www.dlr.de/irs/en) in Bremen was responsible for developing and testing the lander together with CNES. The DLR Institute of Composite Structures and Adaptive Systems (https://www.dlr.de/fa/en) in Braunschweig was responsible for the stable structure of the lander. The DLR Robotics and Mechatronics Center (https://www.dlr.de/rm/en/desktopdefault.aspx/tabid-8017/#gallery/27296) in Oberpfaffenhofen developed the swing arm that allows MASCOT to hop on the asteroid. Das DLR Institute of Planetary Research (https://www.dlr.de/pf/en) in Berlin contributed the MasCam camera and the MARA radiometer. The asteroid lander is monitored and operated fr om the MASCOT Control Center in the Microgravity User Support Center (MUSC)  (https://www.dlr.de/rb/en/desktopdefault.aspx/tabid-4535/)at the DLR site in Cologne.

ЦитатаThe people behind the OPNAV

Notice: This is an English translation of the Japanese article on August 6, 2018. (http://www.hayabusa2.jaxa.jp/topics/20180806/index.html).

After a 300 million km journey from the Earth, Hayabusa2 arrived safely at asteroid Ryugu; a celestial target only 900m in size. A 900m target at a distance of 300 million km is the equivalent to a 6cm target at a distance of 20 thousand km. This means that arriving at Ryugu was like aiming at a 6cm target in Brazil from Japan. Extremely accurate navigation is therefore necessary, and this task fell on the shoulders of the Hayabusa2 Project's OPNAV team.

OPNAV stands for "Optical Navigation" or "光学航法" (kougaku-kouhou) in Japanese. Actually, a more accurate term would be "Hybrid Navigation using Optical and Radiometric Observations", but usually this long phrase is simply referred to as "Optical Navigation". Optical Navigation is a technique to accurately estimate the trajectory of both the spacecraft and the target celestial body by imaging the celestial target with an onboard camera, and communicating with the spacecraft via radio waves. Back in May, we also used the star tracker onboard Hayabusa2 instead of the onboard camera. This was described here, in our article entitled "How the Star Tracker image of Ryugu was used for optical navigation" (http://www.hayabusa2.jaxa.jp/en/topics/20180828e/index.html)

After the ion engine operation for the forward cruise was completed on June 3, 2018, optical navigation using the Optical Navigation Camera - Telescopic (ONC-T) began for the approach to Ryugu. The routine for optical navigation operation is summarized in Figure 1.
(http://www.hayabusa2.jaxa.jp/en/topics/20180828eb/img/fig1.jpg)

In Figure 1, the first four teams listed on the far left accurately measure the position of Ryugu with respect to the background stars from the image captured by the ONC-T. Apart from JAXA, the ground observation team included members who were experts in asteroid observation. The researchers who were involved in this part of the optical navigation were Professor Masateru Ishiguro (Seoul National University), Drs Shin-ichiro Okumura and Seitaro Urakawa (Japan Spaceguard Association) and Dr Daisuke Kuroda (Kyoto University). These four researchers measured the position of Ryugu independently from the images and sent this data to the "navigation team".

The navigation team estimates the trajectory of the spacecraft and Ryugu based on the location data for Ryugu sent by the previous team, and the radio navigation data (range and range rate). The estimated trajectory is then passed to the "guidance team". The guidance team then designs the future trajectory of the spacecraft. The navigation team and guidance team are the "people behind the OPNAV" and we will introduce the members later.

The spacecraft trajectory created by the guidance team is sent to the "operation team" who generate the command to send to the spacecraft. The primary people in charge of the operation team at that time were Drs Takashi Ono、Tomohiro Yamaguchi and Naoko Ogawa from JAXA. The generated command is sent to the spacecraft and the trajectory is corrected. The onboard camera then takes a new image of Ryugu and the loop repeats.

On June 3, this work loop had been performed ten times. In other words, it took ten optical navigation cycles to guide Hayabusa2 safely to the arrival at Ryugu. Since ten loops were performed over about 25 days, this meant operations were conducted every 2 to 3 days. Figure 2 summarized the result of the optical navigation.

Figure 2: Progression of the estimation accuracy for the orbits of the spacecraft and asteroid made using optical navigation. The accuracy in the position of Ryugu (①) and the relative position of Ryugu from Hayabusa2 (②) are indicated. The numerical values written under the spacecraft indicate the distance and relative speed of the spacecraft to the asteroid at that time. There is a 1σ error in the listed value.

As you can see from Figure 2, the error in the position for Ryugu was initially 140km (that is, Ryugu's location could be 140km more or less than the measured value) and the error in the relative position of Ryugu from Hayabusa2 was 500km. However, as the optical navigation was repeatedly performed, the error gradually decreased. Ultimately, the relative position error of Ryugu from Hayabusa2 was reduced to just 0.1km.

Let's now meet the people behind the OPNAV (Figure 3).

ЦитатаHow the Star Tracker image of Ryugu was used for optical navigation

Notice: This is an English translation of the Japanese article on May 25, 2018 (http://www.hayabusa2.jaxa.jp/topics/20180525/).

Fr om May 11 - 14, asteroid Ryugu was imaged (http://www.hayabusa2.jaxa.jp/topics/20180515_e2/) using the Star Tracker onboard Hayabusa2. This data was then used for the application of optical navigation towards the asteroid in this mission.

Around May 20, 2018, Hayabusa2 was about 287 million km fr om the Earth (see Figure 1) and about 40,000 km fr om Ryugu (Figure 2). The exact size of Ryugu is currently unknown, but the diameter is estimated to be around 900 m. This means that it is necessary to arrive at a target of 900 m fr om a distance of about 300 million km travelling from Earth. Such precision requires optical navigation. (For comparison, a 900 m target at a distance of 300 million km is the same as a 6 cm target at a distance of 20 thousand km. This is equivalent of aiming at a 6 cm target in Brazil from Japan.)

Figure 1: The location of Hayabusa2 on May 20, 2018, relative to other celestial bodies projected onto the ecliptic plane. The vernal equinox occurs when the Earth is at the right-side of the Sun and celestial bodies revolve around the Sun counter clockwise.

Figure 2: Location of Hayabusa2 and Ryugu on May 20, 2018. This figure shows the vicinity of Ryugu in Figure.1.

The orbit of a planetary explorer like Hayabusa2 is usually estimated by communicating with the spacecraft via radio waves. The technical term for this method is RARR: Range And Range Rate. "Range" is the distance from the Earth to the spacecraft and is calculated by measuring the round-trip propagation time of radio waves sent from Earth to the spacecraft and back.

"Range rate" is a measurement of the velocity of the spacecraft along the line-of-sight: along the direction to the spacecraft when viewed from Earth. It is calculated from the change in frequency of the transmitted and received radio waves. This effect is commonly known as the "Doppler Effect" and is experienced every time a loud vehicle such as an ambulance passes you on the street. As the ambulance approaches, the sound waves from the siren get bunched together, which increases the frequency of the wave and raises the pitch. When the ambulance retreats into the distance, these sound waves are stretched and their frequency decreases, lowering the pitch. Measuring this frequency change would allow you to estimate the velocity of the ambulance. Likewise, the change in the radio wave frequency from Hayabusa2 allows us to measure the velocity of the spacecraft.

The RARR method can measure the spacecraft's position at 300 million km away to around 300 km. But this is not good enough to arrive safely at Ryugu!

For Hayabusa2, we can use an orbit estimation method called DDOR in addition to RARR. DDOR stands for "Delta Differential One-way Range" and can also be referred to as "relative VLBI", wh ere VLBI is "Very Long Baseline Interferometry". Unlike RARR, DDOR uses two different antennas at widely separated Earth ground stations to receive radio waves from the spacecraft. The difference between the times measured for the radio waves to reach to each station can be used to obtain a more accurate estimate of the spacecraft position. Ideally, this time difference would depend only on the distance between the ground stations. However, delays can also occur due to variations in the Earth's atmosphere. To compensate for this, very distant radio-emitting celestial objects known as "quasars" are also observed. Any distortion due to atmospheric and ionospheric (the upper part of the Earth's atmosphere) can be subtracted from the signal from the spacecraft to get the probe's true distance. DDOR allows the position of Hayabusa2 at 300 million km to be measured to a precision of about several kilometres.

The DDOR measurement for the position of Hayabusa2 is excellent, but there is also uncertainty in the measured position of Ryugu. Since Ryugu cannot transmit radio waves to Earth (and is too distant to allow radio waves to be reflected via radar), DDOR cannot be used to gauge its position. On May 2018, the position of Ryugu was estimated to within 220 km. This means that even if the position of Hayabusa2 can be estimated to within a few kilometres, it would still not be possible to arrive at Ryugu.

This is why we need to use optical navigation. Optical navigation uses knowledge of the direction of Ryugu from the spacecraft to estimate more precisely wh ere the asteroid currently is on its orbit. This is then used to improve the predicted trajectory of Ryugu. To acquire the direction, Ryugu is photographed using a camera onboard Hayabusa2, producing an image containing both the asteroid and background stars. The position of the background stars is precisely known, allowing the direction to Ryugu to be measured. Optical navigation was employed when Ryugu was imaged using the Star Tracker, an instrument usually employed to estimate the orientation of the spacecraft.

A schematic diagram of how finding the direction to Ryugu improves knowledge of the asteroid's trajectory is shown in Figure 3. The blue oval shows the original region prior to optical navigation wh ere Ryugu could potentially lie. By knowing the direction of Ryugu with respect to the background stars, that error range can be shrunk to that indicated by the red brackets. This allows Ryugu's future trajectory to be known with greater precision as Hayabusa2 continues to approach the asteroid.

When we do this in practice, we are able to simultaneously analyze the radio wave and optical navigation data to estimate the orbits of both Hayabusa2 and Ryugu.

Figure 3: The principal of optical navigation by Hayabusa2.

Let's look at how well this works in practice with the images of Ryugu taken by the Star Tracker. Figure 4 is the starry sky seen from Hayabusa2, wh ere Ryugu's expected position over the course of about a week is shown by the line. The orange and green lines and points show the estimated path of Ryugu before and after the trajectory of the probe and asteroid was improved via optical navigation. Yellow points show the actual observed position of Ryugu. On the scale of Figure 4, the expected orbital path of Ryugu before and after optical navigation overlap with the actual observations, so it is not possible to see how much optical navigation improved the predictions.

(http://www.hayabusa2.jaxa.jp/en/topics/20180828e/img/fig4.png)
Figure 4: Results of the optical navigation with the Star Tracker. Orange: Expected position of Ryugu seen from the spacecraft calculated from orbital information prior to using optical navigation. Green: Expected position of Ryugu calculated with greater accuracy using optical navigation data. Yellow: The direction of the observed Ryugu.

In Figure 5, we enlarged the observed area around the 5/13 (May 13) point in Figure 4. In this figure, the expected position and trajectory of Ryugu before and after the optical navigation data was used are plotted along with the observation of Ryugu at that time. The deviation from the true location of Ryugu is much smaller after collecting the optical navigation data.

(http://www.hayabusa2.jaxa.jp/en/topics/20180828e/img/fig5.png)
Figure 5: The effect of optical navigation. This is an enlarged region of Figure 4, centered around the position of Ryugu observed on 5/13. Also shown is the estimate of the asteroid's orbit and position at this time using data before and after optical navigation was employed. The trajectory estimated using optical navigation is closer to the true observation of position.

After the use of optical navigation in May, the uncertainty in the spacecraft position was 3 km, and the uncertainty in the position of Ryugu was 130. This error was still large, but it was not a problem. During this use of optical navigation for Hayabusa2, the spacecraft was still using its ion engines, so the optical navigation result was being used to determine the direction and magnitude of this thrust. At the beginning of June, the period of ion engine operation ends and more precise optical navigation using the onboard Optical Navigation Camera (ONC) will begin. This will ensure our arrival at Ryugu.

※ Hayabusa Flash-back Corner

Hayabusa --our first mission to the asteroids-- also used optical navigation before arrival at asteroid Itokawa. As with Hayabusa2, the first step was an image taken with the Star Tracker. The article (in Japanese) reporting this event on August 15, 2005 can be found here (http://www.isas.jaxa.jp/j/snews/2005/0815_hayabusa.shtml).

The situation for Hayabusa was slightly different to that for Hayabusa2. For the Hayabusa mission, the uncertainty in the position of asteroid Itokawa was smaller than that for Ryugu. This is because radar observations of Itokawa had been possible, allowing the trajectory to be predicted more accurately. Due to Ryugu not approaching the Earth close enough for radar observations since its discovery, the accuracy of the asteroid's orbit is not as good. On the other hand the accuracy of the trajectory of the actual spacecraft was far worse for Hayabusa than for Hayabusa2, as there was not the capacity to properly use DDOR. Therefore, to reach the small celestial body of Itokawa, whose size is only about 500 m, we had to use optical navigation to increase the accuracy of orbit predictions for Hayabusa.

★ Hayabusa2 status(the week of 2018.8.20)★

The spacecraft is currently operating in BOX-B. On August 23, we announced to the media that the point denoted "L08" near the asteroid equator had been selected as the candidate site for the touchdown of Hayabusa2. However, the surface of Ryugu is covered with boulders, so we need to continue gathering and considering information so that we can touchdown safely. The MINERVA-II-1 and MASCOT lander decided to land at mid-latitude sites, N6 and MA-9. MINERA-II-1 separation is scheduled for September 21, and MASCOT on October 3. We are looking forward to seeing what kind of data these will collect!

С 20 по 21 июля Сокол-2 спусткался примерно до 6 км над уровнем поверхности астероида во время режима Box-C. Здесь приведены некоторые из изображений, опубликованных ранее в статье от 25 июля и в статье от 31 июля. Кроме того, на приводимые изображения наложены области-кандидаты на касание и посадки.

Ниже размещены 12 снимков, сделанных в ONC-T (оптической навигационной камерой - телескопической) в режиме Box-C с интервалом примерно 30 °. Для справки также указываются элементы, описывающие положение области выбора места посадки в соответствии с общим снимком, приведённым на рисунке 1 ниже.

На приводимых ниже изображениях обратите внимание на их ориентацию. На рис.1 север Рюгю вверху. Это направление противоположно ранее показанным изображениям (статья 25 июля (http://www.hayabusa2.jaxa.jp/topics/20180725je/index.html) и статья 31 июля (http://www.hayabusa2.jaxa.jp/topics/20180731/index.html)). Север Рюгю направлен к Антарктиде на Земле. Это связано с тем, что Рюгю вращается в противоположном направлении относительно Земли.

ЦитатаAnimation: Asteroidlander MASCOT on board Hayabusa2

DLR (https://www.youtube.com/channel/UC2iaRtEaE3Xbj3wPBot1-ZQ)

Опубликовано: 16 мая 2018 г.

On 3 December 2014, the Japanese space probe Hayabusa2 embarked on a sample return mission to asteroid (162173) Ryugu (formerly designated 1999 JU3). On board is the Mobile Asteroid Surface Scout (MASCOT), a lander built by the German Aerospace Center (Deutsches Zentrum für Luft-und Raumfahrt; DLR) in collaboration with the French space agency CNES. The aim of the Hayabusa2 mission is to learn more about the origin and evolution of the Solar System. As asteroids account for some of the most primordial celestial bodies, researching them gives us a glimpse into our cosmic past. Furthermore, Ryugu is a near-Earth asteroid, which means it could pose a threat to Earth and must be investigated in order to reduce this threat.

ЦитатаDetermination of landing site candidates!

The Landing Site Selection (LSS) conference was held on August 17, 2018 and the candidate landing locations for touchdown, MASCOT and MINERVA-II-1 on the surface asteroid Ryugu were decided. In this article, we introduce the landing candidate spots and the planned dates for these surface operations, along with details of the selection.

Figure 1 is a map of asteroid Ryugu showing the landing candidate locations. Please note the direction of north and south on this map (Note (http://www.hayabusa2.jaxa.jp/en/topics/20180904e/#note1)).

The areas within the colored lines in Figure 1 are the candidate areas for the landing sites for the touchdown of the Hayabusa2 mothership (for sampling), MASCOT and MINERVA-II-1. These are labelled as:

Touchdown:L08 (backup sites: L07, M04)
MASCOT:MA-9
MINERVA-II-1:N6

L08 is the first choice (primary) candidate for the mothership's touchdown, with L07 and M04 as back-up options. The designation "L" and "M" refer to low latitude (L) and mid-latitude (M) positions. The "L" candidate positions were sel ected fr om among 13 preliminary candidate sites, while the "M" location was chosen from a set of four candidate sites. The size of the site selection rectangles are approximately 100m. MA-9 was sel ected as the candidate landing site for MASCOT from ten possibilities, while the N6 candidate for MIENRA-II-1 was chosen fr om seven surface locations.

In Figure 2, each candidate region is shown on the ONC-T image taken during the BOX-C observations at an altitude of 6km. Also in this image, the top of the asteroid is the north pole (Note (http://www.hayabusa2.jaxa.jp/en/topics/20180904e/#note1)). Please do note this is the opposite to the publicly released images so far.

[Note] On the map shown in Figure 1, the north pole of the asteroid is on the top of the map. Public images released so far show the asteroid orientated in the opposite direction, with the direction of the Solar System's north (and for the Earth's North Pole) at the top. Geographical north and south of the asteroid is determined by rotation. As Ryugu rotates retrograde, in the opposite direction to the Earth and the Solar System, the asteroid's northern direction is reversed with respect to the Solar System. The situation is the same for Itokawa. An image with the asteroid's north at the top is therefore reversed compared to an image wh ere the Solar System north points upwards.

★ Hayabusa2 status(the week of 2018.8.27)★

Hayabusa2 has completed operation in BOX-B; observing the asteroid while moving laterally up to 9km while remaining at an altitude of about 20km. As the first rehearsal for touchdown is scheduled to start on 09/11, the spacecraft is now returning to the descent start position. In the first touchdown rehearsal, the spacecraft will descend to 30m or less from the asteroid surface to acquire a more detailed image of the primary touchdown candidate point, L08, and the surroundings. The distance to the asteroid will be measured for the first time using the LRF (Laser Range Finder); a short-distance laser sensor that is used for touchdown. This will be the first time the LRF has been used to measure distance since launch.

ЦитатаImages of Ryugu captured during BOX-C operations

On July 20 - 21, 2018, the Hayabusa2 spacecraft descended to an altitude of about 6km as part of the BOX-C operation. We introduced a few of the images taken at this time in articles on July 25 (http://www.hayabusa2.jaxa.jp/topics/20180725je/index_e.html) and July 31 (http://www.hayabusa2.jaxa.jp/en/topics/20180731e/). The article (http://www.hayabusa2.jaxa.jp/en/topics/20180904e/)discussing the selection of the candidate landing sites also indicates the locations using BOX-C images.

In this post, we show 12 images taken with the ONC-T (Optical Navigation Camera - Telescopic) during the BOX-C operation at approximately 30 degree intervals. We show the original images and the images marked with the landing site candidates below, starting with the complete set of candidates in Figure 1.

Figure 1: Candidate landing sites marked on the photograph of the surface of Ryugu. The area labelled L08 is the candidate touchdown site, with L07 and M04 as back-up locations. MA-9 is the anticipated landing area of MASCOT, while N6 is the scheduled landing area for MINERVA-II-1. (credit: JAXA, University of Tokyo, Kochi University, Rikkyo University, Nagoya University, Chiba Institute of Technology, Meiji University. University of Aizu, AIST.)
The images of the asteroid during the BOX-C operation are shown below, but please pay attention to the image orientation. In both the following and in Figure 1, the north pole of asteroid Ryugu is at the image top. In previous articles on July 25 (http://www.hayabusa2.jaxa.jp/topics/20180725je/index_e.html) and July 31 (http://www.hayabusa2.jaxa.jp/en/topics/20180731e/), the orientation of this image was reversed. The north pole of Ryugu points in the same direction as the south pole on Earth, as Ryugu rotates in the opposite direction to our planet.

Japan's Hayabusa 2 spacecraft is preparing to release three hopping robots to land on asteroid Ryugu in the coming month, with tiny instruments scientists hope will explore the airless world's boulder-strewn landscape and return the first images from the surface of an asteroid.

Two of the landers developed by the Japanese space agency will be deployed together by Hayabusa 2 on Sept. 21, and another landing probe provided by German and French scientists is set for its descent to Ryugu on Oct. 3.

Those landing attempts will be preceded by a landing rehearsal using the Hayabusa 2 spacecraft to approach within 100 feet (30 meters) of Ryugu next week. The spacecraft is scheduled to reach its closest point to the asteroid Sept. 12, low enough to fire and test its laser range finder, a navigation sensor to be used on future touch-and-go maneuvers to snag a sample of Ryugu for return to Earth.

Next week's practice descent will set the stage for a second rehearsal in mid-October

The close-up maneuvers around Ryugu come after more than two months of mapping surveys, revealing Ryugu's appearance for the first time after Hayabusa 2's arrival in late June.

The mission's early reconnaissance of Ryugu allowed scientists to measure its size and mass. The asteroid has a slightly flattened shape, spanning around 1,640 feet (500 meters) in diameter along its equator and approximately 1,440 feet (440 meters) from pole-to-pole.

Ryugu makes one rotation every 7.63 hours and has a mass of roughly 450 million metric tons (496 million tons), yielding a calculation of the asteroid's gravity.

Scientists say Ryugu is a C-type asteroid, suggesting it contains primitive building blocks left over the formation of the solar system 4.5 billion years ago. Managed by the Japan Aerospace Exploration Agency, Hayabusa 2 will bring back specimens of the asteroid's primordial surface for analysis in sophisticated laboratories on Earth.

Hayabusa 2's deployable asteroid landers will make a leisurely descent to Ryugu after separation from the Hayabusa 2 mothership at an altitude of around 200 feet (60 meters). Ryugu's tenuous gravity -- 80,000 times weaker than Earth's gravity field -- will gently tug on the landing probes as they make an uncontrolled free fall to the asteroid, reaching the surface at a speed of less than 1 mph (about 30 centimeters per second).

The first pair of landers to be released Sept. 21 by Hayabusa 2 are carried inside the same container. The MINERVA-II robots, which each weigh a little more than 2.4 pounds (1.1 kilograms), are designed to hop across Ryugu, using cameras, thermometers and other sensors to investigate Ryugu from the surface.

Developed by JAXA, the disk-shaped MINERVA-II landers each have a diameter of 6.7 inches (17 centimeters) -- less than the width of a typical dinner plate -- and stand around 2.7 inches (7 centimeters) tall. The Hayabusa 2 mothership will put the landers on a trajectory to touch down in Ryugu's northern hemisphere.

A third MINERVA-II lander carried by Hayabusa 2 is set to be released for a landing on Ryugu next year.

The mission's largest landing craft is MASCOT -- the Mobile Asteroid Surface Scout -- a joint project by the German and French space agencies. It's due to be released by Hayabusa 2 on Oct. 3.

Conceived and designed by the same team that developed the Philae lander, which made the first soft landing on a comet in 2014, the MASCOT spacecraft will bounce to a rest on Ryugu somewh ere in the asteroid's southern mid-latitudes.

"It's a very small lander," said Tra-Mi Ho, MASCOT's project manager at DLR, the German space agency. It's not bigger than a shoebox, and its weight is not more than 10 kilograms (22 pounds)."

The MASCOT lander "carries four scientific instruments," Ho said. "There is a wide-angle camera called MASCAM. It is there to determine the geology -- the means to investigate the surface features of Ryugu -- and for that it will require imaging at multiple wavelengths.

"We have got a microscope," Ho said in an Aug. 23 press briefing in Japan. "It's a spectral microscope provided by CNES (the French space agency). It is determining the mineralogy. It determines also the content of organic materials and hydrated minerals on the surface -- of the water -- by investigating the spectral features.

"We have a got a thermal radiometer," Ho continued. "It is called MARA. MARA is detecting or investigating the surface temperature of the asteroid. We have got a magnetometer as well, which is called MASMAG. It is there to determine if a magnetic filed exists in the asteroid or in the boulders."

Billed by European scientists as Philae's "little brother," MASCOT carries a self-righting mechanism to orient itself after settling down on Ryugu's surface. The autonomous lander will also try to hop to different positions on the asteroid during its planned 16-hour mission, which is limited by the capacity of the probe's battery.

Ground teams carefully analyzed imagery and science data from Hayabusa 2 to sel ect candidate landing sites for the MINERVA-II and MASCOT spacecraft.

Scientists wanted to ensure none of the landers end up near Hayabusa 2's sampling target, located near Ryugu's equator, and assessed numerous candidate landing sites to find locations relatively free of large boulders. Managers also considered temperature and communications constraints -- all the landers have thermal limits and must relay data back to Earth through Hayabusa 2.

MASCOT science team members ranked their candidate landing sites during an Aug. 14 meeting in Toulouse, France, and briefed their proposal to Hayabusa 2 officials in Japan the following week. The teams announced the landing site selections for the MINERVA-II and MASCOT robots, along with the first of up to three sampling sites for Hayabusa 2, during a press conference Aug. 23.

But despite the diligence by engineers and scientists on Earth, the miniature landers must function in an extreme environment, with temperature swings and an asteroid surface marked with numerous boulders that could pose danger for the tiny robots.

"Ryugu seems to be very homogeneous, so you have got more or less the same composition everywhere," Ho said. "Although we are happy, I think I will have sleepless nights until October," she said. "Until we land there, we still don't know how it looks exactly at the landing site ... So the unknown boulder size distribution at the site, which is critical for MASCOT, is still imposing a risk for our mission."

MASCOT was powered on for testing after Hayabusa 2's arrival at Ryugu, confirming the robot survived its interplanetary cruise inside a carrier bay aboard the Japanese spacecraft. Hayabusa 2 launched on Dec. 3, 2014, and completed its nearly 2 billion-mile (3.2 billion-kilometer) journey to the asteroid June 27.

"MASCOT has been designed to be robust for launch, and on the asteroid, especially for landing," Ho said. "If you consider the MASCOT landing, it's like you drop MASCOT at roughly (a couple of inches) onto a table. So we think, from an impact point of view, it should be robust.

"However, we do not know how the asteroid looks," Ho said. "So, for example, a very unfortunate (scenario) is MASCOT finally settles between two rocks, and it might be trapped."

Hayabusa 2's nano-landers will not be the first spacecraft to achieve a soft landing on an asteroid. That distinction goes to NASA's NEAR-Shoemaker mission, which made a controlled touchdown on asteroid Eros in 2001 and unexpectedly continued beaming science data back to Earth.

But NEAR-Shoemaker did not return any asteroid images fr om the surface of Eros, leaving that "first" in space exploration up for grabs by MINERVA-II and MASCOT.

The Japanese-built MINERVA-II landers are based on a similar craft that flew with Japan's Hayabusa mission to asteroid Itokawa, but that landing attempt was unsuccessful.

Hayabusa 2 is one of two sample return missions that are beginning their asteroid exploration campaigns this year. NASA's OSIRIS-REx mission is scheduled to arrive at asteroid Bennu on Dec. 3, culminating in its own touch-and-go sample grab in mid-2020.

Hayabusa 2 is set to depart the asteroid in late 2019, with return to Earth scheduled for December 2020 with a parachute-assisted landing of the mission's sample carrier in Australia.

ЦитатаThermography of Ryugu by the TIR

We conducted observations of asteroid Ryugu using the Thermal Infrared Imager (TIR) onboard Hayabusa2. Figure 1 shows the thermographic image taken using the TIR at an altitude of 20 km (the home position) fr om Ryugu.

(http://www.hayabusa2.jaxa.jp/en/topics/20180907e/img/tir_thermography_20180630.gif)
Figure 1: Asteroid Ryugu observed with the Thermal Infrared Imager (TIR). The images were captured between 16:02 - 23:45 JST on June 30, 2018 and were taken every eight minutes for one rotation. From the 20 km altitude (home position), one pixel is about 20 m in size. The distance to the Sun at this time is 0.987 au (1 au is about 1.496 billion km, the average annular distance between the Sun and the Earth). The scale bar shows relative temperature (the values have no meaning). Red indicates a high temperature while blue is for colder temperatures.

The image shows the temperature differences on Ryugu's surface during one rotation, with red indicating regions with a high temperature. Distinct regions at different temperatures are captured by the TIR. Features in a thermal image can be seen even if they are in a shaded location in the visible photograph. This lets us confirm that the overall shape of the asteroid is well understood, and also the characteristic topography such as craters and large boulders that show up as a difference in temperature.

A temperature difference can also be seen between the north and south hemispheres of the asteroid. At present, it is summer in the southern hemisphere (the upper part of the figure) and the temperature is higher in this region. In the northern hemisphere in the lower part of the figure, it is currently winter and colder. This difference is due to the inclination of the rotation axis, which results in different levels of radiation reaching the north and south. The TIR has therefore spotted that asteroids also undergo a "seasonal change".

High temperatures on the asteroid reach 100°C, while the coldest regions sit at about room temperature. Temperatures also change depending on the solar distance of the asteroid, lowering as Ryugu moves further away from the Sun.

During the Hayabusa2 mission, we will investigate the formation process of asteroids by examining the characteristics of the surface material revealed by differences in surface temperature. From the TIR data, we can also look for scientifically important landing sites with millimeter-sized grains, and avoid landing Hayabusa2 in severe temperature environments or locations with obstacles such as boulders.

★ Hayabusa2 status(the week of 2018.09.03)★

Last week, we started moving from "BOX-B" and returned to the home position for the spacecraft ("BOX-A") as scheduled. We have continued to observe the asteroid everyday using the onboard cameras, while frantically preparing for the first touchdown rehearsal that will begin from Sept. 11 and the other operations that will follow. This next decent operation will take about two days to complete, but the preparatory work is taking several dozen times that. To get the best results from this preparation, we need to concentrate through this next week.

ЦитатаSchedule for Touchdown 1 Rehearsal 1 (TD1-R1)

The first touchdown by Hayabusa2 to collect samples fr om the asteroid surface is planned for the end of October. The first rehearsal for this operation will be held from September 10 - 12. "Touchdown 1 Rehearsal 1" is abbreviated to TD1-R1. At TD1-R1, the Hayabusa2 will approach the surface of Ryugu to an altitude of less than 40 m. The spacecraft will then rise without landing. The purpose of this rehearsal is to monitor the operation of the spacecraft during touchdown and investigate the safety of the touchdown candidate sites by imaging the surface of Ryugu in their vicinity from a low altitude. The schedule for the TD1-R1 operation is shown in the table below. The actual operation will occur while assessing the situation at that time, so do note that procedures may not always be on schedule.

  • Time: Approximate schedule time (in 5-minute increments). There is a possibility that this may change during operation. The time is the onboard time, so confirmation of the event is the radiowave propagation time of about 17 minutes later.
  • Spacecraft speed: This is the speed relative to the asteroid (minus is towards the asteroid, positive is away). Numerical value is displayed only when speed control is performed. After a speed control operation, the speed changes due to the gravitational force of Ryugu and other celestial bodies.
  • HP altitude:Distance to the center of Ryugu
  • Near point altitude:Distance to the surface of Ryugu.
  • Gate: These are operation checkpoints wh ere it is judged whether to proceed on the basis of the situation of the spacecraft and ground station.

[TD1-R1] Hayabusa2 is now rising after stopping its descent. Spacecraft status is normal. At an altitude of about 600m, descent was autonomously stopped, likely due to the distance measurement by the laser altimeter (LIDAR) becoming impossible due to the low reflectance of Ryugu.

ЦитатаRegarding Touchdown 1 Rehearsal 1 (TD1-R1)

The first operation rehearsal for the first touchdown of Hayabusa2 began on September 10 and during September 11, the spacecraft descended towards Ryugu. Today (September 12), the spacecraft was approaching the planned lowest altitude in the descent when the spacecraft autonomously stopped descending at about 600 m, and started to rise. The cause was that the laser altimeter (LIDAR) became unable to measure the distance between the spacecraft and surface of the asteroid. LIDAR measures distance by reflecting a laser from the asteroid surface. A probable reason for this measurement becoming impossible is the low reflectance of the surface of Ryugu.

The condition of the spacecraft is normal and is today returning to the home position (about 20 km from the asteroid center). From tomorrow, we plan to revise the descent procedure, including a review of the LIDAR settings.

Если я правильно понял -  яркая область с левой стороны связана с эффектом противостояния и внутри него - черная точка тени Hayabusa2
(https://testforum.novosti-kosmonavtiki.ru/forum/file/87667)
Не совсем понимаю, как такое изображение получили.
Если тень легла левее центральной оси изображения, то солнце должно быть правее, и соответственно лучше должна быть освещена правая сторона. 
На изображении всё наоборот - максимально освещена левая часть. Чем правее, тем менее освещённость.
Так может быть только если солнце слева. Тогда тень не от Hayabusa, а от другого объекта который расположен между солнцем и Ryugu.

Может кто-то подсказать, как этот ребус расшифровать? :)

ЦитатаThe spacecraft shadow and opposition effect

The first operation rehearsal (http://www.hayabusa2.jaxa.jp/en/topics/20180911e/) for the first touchdown of Hayabusa2 was performed fr om September 10 - 12. The spacecraft reached an altitude of about 600 m from the surface of Ryugu and then began to ascend once again (http://www.hayabusa2.jaxa.jp/en/topics/20180912e/). During the operation, the images taken for navigation purposes with the Optical Navigation Camera Wide angle (ONC-W1) were released in real time (http://www.hayabusa2.jaxa.jp/en/galleries/onc/nav20180911/). The last image captured is shown in Figure 1. This photograph was taken on September 12 at around 12:40 JST at an altitude of 635m from the surface of Ryugu.
(http://www.hayabusa2.jaxa.jp/en/topics/20180915e/img/Fig1a.jpg) (http://www.hayabusa2.jaxa.jp/en/topics/20180915e/img/Fig1b.jpg)
[Enlargement (left, a)] (http://www.hayabusa2.jaxa.jp/en/topics/20180915e/img/Fig1a.jpg) [Enlargement (right, b)] (http://www.hayabusa2.jaxa.jp/en/topics/20180915e/img/Fig1b.jpg)
Figure 1: Ryugu captured with the ONC-W1 on September 12, 2018 at around 12:40 JST. The distance to the surface of Ryugu is about 635m. In this image, the south pole of Ryugu is at the top as the asteroid rotates in the opposite direction to the Earth. (b) The region within the red circle is brightened due to the opposition effect. The black dot indicated by an arrow is the shadow of Hayabsua2. (Image credit: JAXA).

In this image, the left-hand side (within the red circle in Figure 1b) appears brightened due to a phenomenon known as the "opposition effect". It is a phenomenon that occurs when the angle formed between the Sun - the celestial body surface - observation point (known as the "phase angle" ) is close to zero, resulting in the celestial body being illuminated from directly behind the observation point and creating a bright region. In the center of the bright part is a black dot but this is the shadow of Hayabusa2. The sunlight is behind the spacecraft, casting the shadow on the asteroid.

It is easier to see that this dot is the shadow of the probe in an animation. Figure 2 shows the image sequence of Hayabusa2's descent.

http://www.hayabusa2.jaxa.jp/en/topics/20180915e/img/Fig2.mp4 (http://www.hayabusa2.jaxa.jp/en/topics/20180915e/img/Fig2.mp4)

Figure 2: An animation created from images taken with the ONC-W1 during the time the spacecraft was approaching Ryugu (from September 11, 2018 at around 14:00 JST to September 12, 2018 at around 13:00 JST). (Image credit: JAXA)

The animation shows Ryugu increase in size during the approach and the shadow of Hayabusa2 can be seen near the end. Notice that the shadow of Hayabusa2 does not move even as Ryugu rotates and as the distance decreases, the shadow expands. It also appears to be fixed on the screen. To understand this, please check out the "A little more detail" section below.

Hayabusa2 is about 6m in size and is casting a shadow on a roughly 900m object, 300 million km from the Earth. That this could be captured in a photograph is quite breathtaking, don't you think? Hayabusa2 may only be small, but the spacecraft is very brave!

■A little more detail

Here we explain a little more about the motion of the shadow of Hayabusa2 and opposition effect. The relative position of the celestial bodies when Figure 1 was captured is shown in Figure 3. Since Hayabusa2 is in the immediate vicinity of Ryugu, it is in the same location as the marker for Ryugu but approaches the asteroid along the line connecting Ryugu to the Earth.

(http://www.hayabusa2.jaxa.jp/en/topics/20180915e/img/Fig3.png)
Figure 3: Arrangement of the celestial bodies on September 12, 2018. The figure is projected on the ecliptic plane (the plane in which the Earth orbits the Sun) along the north axis of the Solar System (also the North Pole of the Earth). In this figure, the celestial bodies revolve counterclockwise around the Sun. (Figure credit: JAXA).

If we enlarge the diagram near Ryugu, the system looks like that shown in Figure 4.

(http://www.hayabusa2.jaxa.jp/en/topics/20180915e/img/Fig4.png)
Figure 4: Schematic diagram close to Ryugu. (Figure credit: JAXA)

As shown in Figure 4, Hayabusa2 descends along the line connecting the Earth with the center of Ryugu. The Sun is shining diagonally from the right of the figure. As Hayabusa2 descends, the shadow of the spacecraft appears on the left side of Ryugu and moves to the right.

Since the sunlight can be thought of as parallel rays, the angle θ in Figure 4 hardly changes during the short time the spacecraft descends. This means that the direction in which the shadow can be seen remains almost the same during the descent so that it appears as if the position of the shadow is fixed in the animation shown in Figure 2.

We know that the Sun is in the opposite direction to wh ere shadows fall and that the surroundings directly opposite the Sun appear brighter than their surroundings. This is the opposition effect. Figure 5 shows a simplified schematic of this situation. When the angle formed by the direction of the Sun's rays and the line of sight (α: phase angle) is close to zero, the light reflected by the celestial body will be at its strongest.

(http://www.hayabusa2.jaxa.jp/en/topics/20180915e/img/Fig5.png)
Figure 5: Explanation of the opposition effect. (Figure credit: JAXA.)

The opposition effect was also seen when Hayabusa explored Itokawa (Figure 6).

(http://www.hayabusa2.jaxa.jp/en/topics/20180915e/img/Fig6.jpg)
Figure 6: The shadow of Hayabusa at the "Muses sea" (the official name is the MUSES-C Regio) on asteroid Itokawa and the opposition effect (November, 2005). (From http://www.isas.jaxa.jp/j/special/2008/hayabusa/11.shtml)

If we approach Ryugu still closer, we should see the shadow of Hayabusa2 clearly as with the shadow of Hayabusa in Figure 6. This may be what we see on our next approach.

Тогда у меня тоже вопрос. Хаябуса сейчас на расстоянии чуть больше одной астрономической единицы от Солнца. То есть угловой размер Солнца примерно такой же, как на Земле. Размеры Хаябусы около 5 метров. Если так, то с расстояния 635 метров и больше, она не могла отбрасывать полную тень. Значит, это полутень. Но если так, она же не должна увеличиваться, не так ли?

★ Hayabusa2 status(the week of 2018.09.10)★

The first half of the week was devoted to the landing rehearsal operation (TD1-R1). The operation was suspended at an altitude of 600m, and the spacecraft returned to the base camp 20 km home position. Although TD1-R1 was interrupted, we were able to see the response of Hayabusa2 at low altitude and gain a valuable image of the landing candidate area at high resolution. The Project Team feels that we are narrowing down the unexplored areas step by step. Our analysis of this data continues for the upcoming rover separation and landing operation.

ЦитатаThe small exploration rovers, MINERVA-II1

The MINERVA-II (standing for the "MIcro Nano Experimental Robot Vehicle for Asteroid, the second generation") are a successor to the exploration rover, MINERVA, that was installed with the first Hayabusa mission to asteroid Itokawa.

Two containers for MINERVA-II1 and MINERVA-II2 are mounted on the bottom of the Hayabusa2 spacecraft. Two rovers are stored within the MINERVA-II1 container and one rover sits in the MINERVA-II2 container (Figure 1). This September, the two MINERVA-II1 rovers within the first container will be deployed, while the MINERVA-II2 deployment is scheduled for next year.

The two MINERVA-II1 rovers (Rover-1A, 1B) are hexagonal in shape with a diameter of 18cm, height of 7cm and weight of about 1.1 kg each (Figure 2). The pair were developed at the JAXA Institute of Space and Astronautical Sciences in collaboration with the following manufacturers, universities and organizations:

Figure 2: The small rovers, MINERVA-II1. Rover-1A is on the left and Rover-1B is on the right. Behind the rovers is the cover in which they are stored. (Image credit: JAXA).

There are four cameras on Rover-1A and three cameras on Rover-1B. We are planning to use the cameras on each rover to create a stereo image of the surface of Ryugu. Some of the projections from the rover edge that looks like thorns are temperature sensors to measure the surface temperature of Ryugu. Additional instruments on the rovers include optical sensors, an accelerometer and a gyroscope.

The rovers communicate with Hayabusa2 using the repeater (OME-E) installed on the main spacecraft. The maximum communication speed is 32 kbps. Data received by Hayabusa is then transferred to the Earth. The OME-E will also be used for communication with the German/French lander, MASCOT, scheduled for deployment in October.

The main feature of MINERVA-II1 is the ability for the rovers to move on the surface of Ryugu by utilizing a hopping mechanism (Figure 3). Within the rover is a motor that rotates and causes the rover to "hop" (jump up) during the rebound. This will allow the rovers to move across the asteroid surface and explore multiple areas. On Ryugu, MINERVA-II1 will move autonomously, determining what should be done for the exploration by itself.

Gravity on the surface of Ryugu is very weak, so a rover propelled by normal wheels or crawlers would float upwards as soon as it started to move. Therefore this hopping mechanism was adopted for moving across the surface of such small celestial bodies. The rover is expected to remain in the air for up to 15 minutes after a single hop before landing, and to move up to 15 m horizontally.

Японский зонд спустит на Рюгу двух прыгающих роботов
На этой неделе космический аппарат «Хаябуса-2» должен спустить на поверхность астероида Рюгу два маленьких ровера.

На прошлой неделе команда «Хаябуса-2» начала подготовку к серьезному этапу своей миссии. Согласно графику, 19 сентября аппарат должен был приблизиться к Рюгу, чтобы в итоге спустить на него два небольших дискообразных робота -- MINERVA-II1A и MINERVA-II1B. Если не возникнет проблем, операцию проведут (https://www.space.com/41885-hayabusa2-rovers-landing-on-asteroid-soon.html) в ночь с 20 на 21 сентября.

Каждый ровер MINERVA-II весит 1,1 килограмма и обладает размерами 18 сантиметров в ширину и семь сантиметров в высоту. По поверхности астероида они будут передвигаться довольно необычным способом -- перепрыгивая с места на место.  

 «Гравитация на поверхности Рюгу очень слабая, так что вездеход, передвигающийся (https://naked-science.ru/article/sci/stanciya-hayabusa-2-pribyla-k) на обычных колесах или гусеницах, стал бы «всплывать», как только начал бы движение, -- сообщают члены команды «Хаябуса-2» в описании к MINERVA-II1. -- Таким образом, мы адаптировали этот прыгающий механизм для передвижения по таким малым небесным телам. Ожидается, что после прыжка ровер будет находиться над поверхностью до 15 минут, прежде чем он опустится обратно на поверхность, переместившись на 15 метров по горизонтали».

 Вездеходы будут передвигаться автономно, исследуя поверхность 950-метрового Рюгу. При помощи научных инструментов, в том числе температурных и оптических сенсоров, акселерометров, гироскопов и семи камер на двоих, роботы соберут (https://naked-science.ru/article/nakedscience/vse-sokrovishcha-vselennoy) большой объем данных.

 В следующем году зонд «Хаябуса-2» также совершит (https://naked-science.ru/article/sci/nedaleko-ot-zemli-obnaruzhen-dvoynoy) несколько спусков на поверхность Рюгу для сбора материала. Орбитальный аппарат покинет астероид в декабре 2019-го и через год привезет на Землю образцы в специальной капсуле.

 Ученые детально изучат грунт и камни, чтобы узнать о ранней истории Солнечной системы и роли астероидов, которую они могли сыграть в зарождении жизни на Земле.

Hayabusa-2 has braked its approach speed from 0.4 m/s to 0.1 m/s; as of 1730 UTC Sep 20 it has just passed the 4 km mark on its approach to Ryugu. A naive calculation suggests it will reach the vicinity of the surface in another 11 hours!

A Senior NASA scientist I know described Hayabusa and Hayabusa2 as "sporty". Their approach is so different from NASA's. Always on a shoestring, always daring, always risking failure. Neither approach is better; humanity is better for having both safe and "sporty" exploration!

"Старший научный сотрудник НАСА, которого я знаю, описал (программы) Хаябуса и Хаябуса 2 как "лихие". Их подход совершенно отличается от НАСА. Всегда на мели, всегда дерзко, всегда рискуешь провалом. Ни один из подходов не лучше. Человечеству лучше иметь два подхода в исследованиях - безопасный и рискованный."

ЦитатаMINERVA-II1: Successful image capture, landing on Ryugu and hop!

On September 21, the small compact MINERVA-II1 rovers (http://www.hayabusa2.jaxa.jp/en/topics/20180919e/) separated from the Hayabusa2 spacecraft (time of separation was 13:06 JST). The MINERVA-II1 consists of two rovers, Rover-1A and Rover-1B. We have confirmed both rovers landed on the surface of asteroid Ryugu. The two rovers are in good condition and are transmitting images and data. Analysis of this information confirmed that at least one of the rovers is moving on the asteroid surface.

MINERVA-II1 is the world's first rover (mobile exploration robot) to land on the surface of an asteroid. This is also the first time for autonomous movement and picture capture on an asteroid surface. MINERVA-II1 is therefore "the world's first man-made object to explore movement on an asteroid surface". We are also delighted that the two rovers both achieved this operation at the same time.

The following is a picture sent from MINERVA-II1.

The MINERVA-II1 cameras can shoot in color. In Figure 1, although the image is blurred due to the rover rotating, you can clearly see the body of Hayabusa2 and the paddle of the solar cells. The solar paddle appears blue. In Figure 3, the image was taken during a hop on the surface and you can feel this dynamic movement.

Operation of MINERVA-II1 will continue from now on. We are planning to acquire more data for analysis.

Comments from Project Members
■ Tetsuo Yoshimitsu, Responsible for the Hayabusa2 Project MINERVA-II1.
Although I was disappointed with the blurred image that first came from the rover, it was good to be able to capture this shot as it was recorded by the rover as the Hayabusa2 spacecraft is shown. Moreover, with the image taken during the hop on the asteroid surface, I was able to confirm the effectiveness of this movement mechanism on the small celestial body and see the result of many years of research.

■ Takashi Kubota, Spokesperson for the Hayabusa2 Project (also responsible for the MINERVA-II1)
The good news made me so happy. From the surface of Ryugu, MINERVA-II1 sent a radio signal to the ground station via Hayabusa2 S/C. The image taken by MINERVA-II1 during a hop allowed me to relax as a dream of many years came true. I felt awed by what we had achieved in Japan. This is just a real charm of deep space exploration.

■ Yuichi Tsuda, Hayabusa2 Project Project Manager
I cannot find words to express how happy I am that we were able to realize mobile exploration on the surface of an asteroid. I am proud that Hayabusa2 was able to contribute to the creation of this technology for a new method of space exploration by surface movement on small bodies.

■ Makoto Yoshikawa, Hayabusa2 Project Mission Manager
I was so moved to see these small rovers successfully explore an asteroid surface because we could not achieve this at the time of Hayabusa, 13 years ago. I was particularly impressed with the images taken from close range on the asteroid surface.

МОСКВА, 23 сен -- РИА Новости. Японское агентство аэрокосмический исследований (JAXA) опубликовало фотографии с поверхности астероида Рюгу.

Фотографии были получены после того, как два японских ровера, запущенных с зонда "Хаябуса-2", совершили первую в истории успешную посадку на поверхность астероида и смогли отправить фотографии.

Роверы отделились от зонда 21 сентбяря. Как сообщается на сайте JAXA, аппараты находятся в рабочем состоянии. При этом как минимум один из роверов продолжает движение по поверхности астероида.

The MINERVA-II-1A rover captured this blurred image Saturday at 0244 GMT (10:44 p.m. EDT Friday) showing asteroid Ryugu as the robot hopped across its surface. The bright feature on the right side of the image was caused by sunlight. Credit: JAXA

A pair of tiny automated robots touched down on asteroid Ryugu on Friday after separating from Japan's Hayabusa 2 spacecraft, sending back pictures as the probes bounced across the asteroid's alien landscape nearly 200 million miles from Earth.

The miniature rovers, each smaller than the diameter of a typical dinner plate, were released from the Hayabusa 2 spacecraft Friday as the spacecraft descended within 200 feet (as close as 55 meters) from Ryugu.

"The good news made me so happy," said Takashi Kubota, a spokesperson for the Hayabusa 2 mission. "The image taken by MINERVA-II-1 during a hop allowed me to relax as a dream of many years came true. I felt awed by what we had achieved in Japan. This is just a real charm of deep space exploration."

Carried aboard the Hayabusa 2 spacecraft since its launch from Earth in December 2014, the disk-shaped MINERVA-II robots floated down to the asteroid, tugged by Ryugu's tenuous gravity -- 80,000 times weaker than Earth's -- until they reached the surface at a speed predicted to be less than 1 mph (about 30 centimeters per second).

The robots returned imagery and science data to controllers on Earth via the Hayabusa 2 mothership, showing smeared views of Ryugu's boulder-strewn surface and the Hayabusa 2 spacecraft itself as the landers tumbled toward the asteroid.

Officials from the Japan Aerospace Exploration Agency confirmed Friday that the MINERVA-II robots separated from Hayabusa 2 as planned. The Hayabusa 2 team provided play-by-play updates on Hayabusa 2's descent toward Ryugu from a "home position" around 12 miles (20 kilometers) from the asteroid, tweeting images from the craft's navigation camera as it maneuvered closer to the asteroid.

In a press conference Friday following the deployment of the MINERVA-II rovers, Japanese scientists said they received data from the landers as they headed toward the asteroid.

JAXA released the first images from both rovers Saturday, and confirmed at least one of the nano-probes -- Rover-1A -- was moving across the asteroid surface, using an internal mechanism to hop to different locations on Ryugu. No previous mission has hopped to different locations on an asteroid, or returned images from an asteroid's surface.

"The two rovers are in good condition and are transmitting images and data," JAXA said in a statement Saturday. "Analysis of this information confirmed that at least one of the rovers is moving on the asteroid surface."

So far, none of the images released by JAXA were captured on Ryugu, but the robots are covered in solar cells, allowing their batteries to be recharged for continued operations.

"I cannot find words to express how happy I am that we were able to realize mobile exploration on the surface of an asteroid," said Yuichi Tsuda, Hayabusa 2's project manager, in a JAXA statement. "I am proud that Hayabusa2 was able to contribute to the creation of this technology for a new method of space exploration by surface movement on small bodies."

Japanese scientists celebrated the feat, which came 13 years after Japan's predecessor Hayabusa mission deployed a similar lander at asteroid Itokawa. But the first MINERVA rover missed Itokawa and floated off into space.

"I was so moved to see these small rovers successfully explore an asteroid surface because we could not achieve this at the time of Hayabusa, 13 years ago," said Makoto Yoshikawa, Hayabusa 2's mission manager. "I was particularly impressed with the images taken from close range on the asteroid surface."

MINERVA stands for MIcro Nano Experimental Robot Vehicle for Asteroid, and Hayabusa 2 carried three second-generation MINERVA-II rovers. The third lander will be released for another descent to Ryugu some time next year.

Another lander, slightly bigger than the MINERVA-II rovers, is set for a descent to asteroid Ryugu on Oct. 3. The Mobile Asteroid Surface Scout, or MASCOT, lander was jointly developed by the German and French space agencies and measures about the size of a shoebox.

Like the Japanese-built MINERVA-II rovers, MASCOT will attempt to hop to different locations on Ryugu, taking pictures and collecting scientific measurements about the asteroid's environment and composition.

The MINERVA-II robots each weigh a little more than 2.4 pounds (1.1 kilograms), and carry cameras, thermometers and other sensors to investigate Ryugu from the surface. The MINERVA-II landers each have a diameter of 6.7 inches (17 centimeters) and stand around 2.7 inches (7 centimeters) tall.

"Although I was disappointed with the blurred image that first came from the rover, it was good to be able to capture this shot as it was recorded by the rover as the Hayabusa 2 spacecraft is shown," said Tetsuo Yoshimitsu, a member of the Hayabusa 2 team responsible for the MINERVA-II rovers. "Moreover, with the image taken during the hop on the asteroid surface, I was able to confirm the effectiveness of this movement mechanism on the small celestial body and see the result of many years of research."

The Hayabusa 2 mothership was responsible for placing the landers on a trajectory toward Ryugu's northern hemisphere.

NASA's NEAR-Shoemaker mission was the first spacecraft to achieve a soft landing on asteroid, when it made a controlled touchdown on Eros in 2001 and unexpectedly continued beaming science data back to Earth. But NEAR-Shoemaker did not return any asteroid images from the surface of Eros, leaving that "first" in space exploration still up for grabs.

Hayabusa 2 arrived at Ryugu in late June, kicking off more than a year of mapping, scientific surveys and a series of descents toward the asteroid to drop off landers and pick up rock samples for return to Earth.

The mission's early reconnaissance of Ryugu allowed scientists to measure its size and mass. The asteroid has a slightly flattened shape, spanning around 3,280 feet (1 kilometer) in diameter along its equator and approximately 2,880 feet (880 meters) from pole-to-pole.

Ryugu makes one rotation every 7.63 hours and has a mass of roughly 450 million metric tons (496 million tons), yielding a calculation of the asteroid's gravity.

Scientists say Ryugu is a C-type asteroid, suggesting it contains primitive building blocks left over the formation of the solar system 4.5 billion years ago. Managed by the Japan Aerospace Exploration Agency, Hayabusa 2 will bring back specimens of the asteroid's primordial surface for analysis in sophisticated laboratories on Earth.

The spacecraft is scheduled to attempt to collect the first of three samples from Ryugu as soon as late October, using a pellet fired into the asteroid to force surface material through a funnel into a collection chamber. Hayabusa 2 rehearsed its descent maneuvers for the first time earlier this month, but aborted the approach after its laser navigation sensor was unable to provide range and closure rate information to the probe's computer.

Engineers blamed the miscue on Ryugu's dark, unreflective surface, and adjusted settings on the laser navigation sensor to prevent the problem from recurring in the future. No such issues were reported Thursday or Friday as Hayabusa 2 deployed the MINERVA-II landers.

Once it has specimens from Ryugu, Hayabusa 2 will fire its ion engines and depart Ryugu late next year, heading for a landing in Australia in December 2020.

★ Hayabusa2 status(the week of 2018.09.17)★

This week was very exciting. On September 19, preparation began for the separation of the MINERVA-II1 rovers. Descent from the home position began at around 14:00 JST on September 20. On September 21 after 13:00 JST, the two MINERVA-II1 rovers, Rover-1A and Rover-1B separated from the spacecraft. After this, the spacecraft rose and returned to the home position at around 15:00 JST on September 22. After separation, we attempted communication with MINERVA-II1. By September 22, images and data confirmed that both rovers had landed on Ryugu and that at least one was hopping and moving. We published a press release on September 22, releasing the situation of MINERVA-II1 and the acquired images. The Project Members were also very impressed by these images sent from MINERVA-II1.

ЦитатаImages of Ryugu photographed fr om BOX-B

The BOX-B operation ran between August 18 and September 7. Here, we explore the images taken fr om BOX-B.

Hayabusa2 usually stays at the home position, about 20 km fr om Ryugu. The direction of the spacecraft is also fixed as the home position for Hayabusa2 is situated on the line connecting Ryugu and the Earth. During this exploration period, the Earth and Sun could be seen in almost the same direction from view point of Ryugu. That meant that if the spacecraft were to stay at the home position, Ryugu would appear similar to an almost full moon. This is convenient as almost all of Ryugu is illuminated, but it is important to observe the asteroid not only from the front but also from diagonal directions. To achieve these different viewing angles, we initiated the BOX-B operation.
A schematic of the BOX-B operation is shown in Figure 1. The spacecraft started from the home position on August 18, initially moving north of the ecliptic plane to reach 9 km on August 24. Hayabusa2 remained at this new location for about one day. From there, it was easier to observe the south pole side of Ryugu (the asteroid rotates in the opposite direction to the Earth, so the Earth's north pole is Ryugu's south pole). Hayabusa2 then moved diagonally, moving to a position on August 31 wh ere the evening side of Ryugu was easy to see. After spending one day in this location, the spacecraft returned to the original home position on September 7. This was the BOX-B operation. As the observations were gathering during this travel, we sometimes also refer to this as the "observation tour".

Here we take a look at the images taken during the BOX-B operation. First is Figure 2, which shows an image of the south pole side of Ryugu. There is a large boulder near the south pole, and if we include the smaller rock masses as well, we can see that the vicinity of the south pole is also covered with boulders.

On the left-hand side of the ONC-T image, you can clearly see the shadows from the asteroid's bumpy surface wh ere the Sun is setting. Comparing the far-left side with the TIR infrared image, you can also see that the ONC-T frame includes a region on the nightside of Ryugu from which no light was reflected. The TIR image indicates high temperature regions in red and low temperature regions in blue, from which it can be easily seen that the temperature drops on the night side of Ryugu. Evening observations like this one allow us to understand the appearance of the irregular surface features as well as the changes in temperature the asteroid experiences.

In this BOX-B operation, we observed the south side and evening side of Ryugu. The reason for observing the south side was to investigate the large boulder in detail. The evening side was observed as it was an easy to reach during this operation of the spacecraft. Additionally, as the region observed covered noon through to night, it was a good opportunity to investigate the drop in temperature. The next BOX-B operation is not currently scheduled, but a good candidate for the future observation tour would be the north pole side and the dawn side of Ryugu.

ЦитатаConfirmation of landing candidate sites from the rehearsal operation

From September 10 to 12, we conducted the Touchdown 1 Rehearsal 1 (TD1-R1) operation and were able to confirm the selection of the candidate sites for touchdown. Figure 1 shows an image taken from about 3km above the asteroid surface using the Optical Navigation Camera - Telescopic (ONC-T).

In the right-hand image of Figure 1, the areas for the touchdown candidate sites are marked out. L08 is the primary touchdown candidate site, while L07 and M04 are the back-up choices. Part of L07 extends slightly beyond the image, but most of that area is captured.

Touchdown operations will continue to be studied from now on.

ЦитатаОпубликовано первое в истории видео с поверхности астероида
16:41 27.09.2018 (обновлено: 17:35 27.09.2018)

МОСКВА, 27 сен - РИА Новости. Пара роверов MINERVA-II1 передали на Землю новые фотографии с поверхности астероида Рюгю, а также небольшое видео, сообщает на своем сайте японское агентство аэрокосмических исследований JAXA (http://www.hayabusa2.jaxa.jp/en/topics/20180927e_MNRV/).

"Своеобразные "шпильки", которые можно увидеть на одной из фотографий, украшают поверхность роверов не просто так, они решают сразу три задачи. Они помогают сильнее цепляться за поверхность астероида во время прыжка, защищают солнечные батареи от повреждений и содержат датчики температур", -- отмечают специалисты агентства.
Автоматическую станцию "Хаябуса-2" запустили в космос в декабре 2014 года для изучения и забора проб на астероиде Рюгю. Как надеются ученые, она привезет на Землю первые абсолютно чистые образцы первичной материи Солнечной системы.

Японский аппарат достиг цели в начале июня и начал длительную процедуру торможения и сближения с астероидом.

Забор грунта, несмотря на то, что "Хаябуса-2" давно достигла Рюгю, произойдет только через несколько недель. Сначала зонд должен определить положение на орбите и скорректировать ее, если возникнет такая необходимость, а затем -- всесторонне изучить структуру недр и рельеф астероида.

Только после этого межпланетная станция сблизится с поверхностью Рюгю и сбросит на нее своеобразный "взрывпакет", который выбросит нетронутый материал из недр астероида. "Хаябуса-2" соберет эту пыль и гальку, левитирующую в вакууме, во время второго пролета над точкой.

Помимо этого, "Хаябуса-2" доставила к астероиду три спускаемых аппарата - два японских ровера MINERVA-II1, аналог которых был отправлен к астероиду Итокава вместе с "Хаябусой-1" в далеком 2003 году, а также европейский аппарат MASCOT.

Роботы Rover-1A и Rover-1B успешно достигли поверхности Рюгю в минувшие выходных. Они сделали множество фотографий и собрали массу научных данных, которые сейчас обрабатываются специалистами JAXA.

Новая порция фотографий, а также первое в истории видео с поверхности астероида, передали на Землю в середине недели после очередного "прыжка" роверов по поверхности Рюгю. Пока все инструменты и солнечные батареи аппаратов работают нормально.

В начале октября к ним присоединится европейский MASCOT. Он совершит посадку в районе экватора, приступит к изучению структуры недр Рюгю и к наблюдению за магнитными полями.

ЦитатаMascot radiometer (MARA)

The DLR Institute for Planetary Research provides a radiometer and a camera for the MASCOT (http://www.dlr.de/irs/desktopdefault.aspx/tabid-7902/13482_read-34316/) Lander, which is being developed in cooperation with the French space agency CNES. MASCOT is part of the scientific payload of JAXA's Hayabusa II mission, which will investigate the near Earth asteroid 1999JU3 in 2018, to bring back samples in 2020. Apart from the camera and radiometer, MASCOT is equipped with a spectrometer and magnetometer. The measurements to be performed will characterize the asteroid on small scales in situ, and help to choose a site for sample collection.

The MASCOT radiometer MARA measures the radiometric flux emitted from the asteroid's surface in 6 different infrared bands (Figure 1). Two long-pass channels are used to determine the surface brightness temperature, while 4 bandpass channels will determine the spectral characteristics of the surface. A comparison with spectra measured in the laboratory will then allow for a characterization of surface materials and the asteroid's composition.

ЦитатаMASCOT: Attitude Determination System

The Mobile Asteroid Surface Scout (MASCOT) is a small landing package build by the German Aerospace Center (DLR) jointly with the French National Center for Space Studies (CNES). MASCOT is flying aboard the Japanese space probe Hayabusa-II, built by the Japan Aerospace Exploration Agency (JAXA). The probe has been launched on December 3rd, 2014 for a five year sample return mission to the Near-Earth Asteroid Ryugu (1999 JU3). The lander is equipped with four science instruments which will take detailed close-up pictures and make a variety of in-situ measurements. MASCOT has a cubic shape, roughly 29 x 27.5 x 20 cm, and weighs about 10 kg. An internal mechanism with an eccentric tappet can be used to reorient MASCOT if needed and relocate to a different site to change and increase its investigation area.

Test der Lagebestimmung mit dem MASCOT-Referenzmodell

After arrival and characterization of the asteroid, MASCOT will be dropped from the Hayabusa-II mothership and will land passively on the asteroid surface. Before starting science measurements, MASCOT must lie on the correct side.

(https://www.dlr.de/irs/en/Portaldata/46/Resources/2015_images/abteilungen/abteilungsaktivitaeten/MASCOT-300x226.png)
MASCOT-Trajektorien und Sensor-Simulation
The attitude determination system consists of two types of sensors: solar cell-based Sun sensors on each side of MASCOT as well as five optical proximity sensors (OPS). The latter consists of a LED and a photodiode which can detect the reflected LED light when MASCOT is in proximity to the surface.

A histogram filter is used for attitude determination and multi-sensor data fusion. It is a Bayesian filter used to estimate states which can be divided in a finite number of possible values. This is useful for MASCOT, since all that is needed is an estimation of the side on which it is lying.

The GNC systems department is responsible for this attitude determination system. This includes concept design, sensor selection and procurement, algorithm development, simulation, software requirements, testing on software level as well as Hardware-in- the-Loop and mission support.

MASCOT's swing arm

Mov­ing around on small bod­ies is dif­fi­cult, be­cause the grav­i­ta­tional pull and thus the fric­tion be­tween a lan­der and the ground is very small. Con­ven­tional means of trans­port, such as wheels or chains, are based on trac­tion and are thus un­suit­able for use on as­ter­oids. There­fore, a mo­bil­ity mech­a­nism was de­vel­oped for MAS­COT in order to en­able move­ment in such an en­vi­ron­ment: the lan­der is equipped with a swing arm that ac­cel­er­ates and de­cel­er­ates an ec­cen­tri­cally mounted mass. The re­sult­ing re­ac­tion forces, in turn, allow the lan­der to push it­self away from the ground. As the grav­i­ta­tional pull is very low, even small push-off forces can re­sult in big jumps: a dis­tance of 17 me­tres can be achieved with an ini­tial speed of only five cen­time­tres per sec­ond. The grav­i­ta­tional ac­cel­er­a­tion on the sur­face of Ryugu is only 0.00015 me­tres per sec­ond squared and is thus 60.000 times lower than on Earth (9.81 m/s2).

Test­ing out this mech­a­nism on Earth, how­ever, proved very dif­fi­cult, as the tra­di­tional meth­ods for test­ing in mi­cro­grav­ity con­di­tions could not be put to any mean­ing­ful use. On par­a­bolic flights, the grav­ity is zero on av­er­age, but there is also high-fre­quency ac­cel­er­a­tion, which, al­though low, nev­er­the­less dom­i­nates any move­ment caused by the mo­bil­ity. In ad­di­tion, the ac­cel­er­a­tion on the MAS­COT lan­der should not be brought down to zero, but must be pre­cisely re­duced to a very low value to mimic the con­di­tions on Ryugu. For two-di­men­sional prob­lems, it is com­mon to use a pneu­matic table for test­ing, which is based on the same prin­ci­ple as air hockey. Bod­ies can move freely across the plane of the table and ro­tate around the ver­ti­cal axis. Gen­tly tilt­ing the table also in­tro­duces a slight force of grav­ity. How­ever, the mech­a­nism is de­signed to make MAS­COT ro­tate around all three axes: as the ac­cel­er­ated mass is ec­cen­tri­cally mounted, it cre­ates torques around all of the axes in ad­di­tion to the ro­tat­ing cen­trifu­gal force in the plane of the arm. The re­sult is that, with every mo­tion, MAS­COT is mov­ing and ro­tat­ing in three di­rec­tions, while at the same time shift­ing its cen­tre of grav­ity. This also makes coun­ter­bal­anc­ing the weight force with a he­lium bal­loon dif­fi­cult in tests con­ducted on Earth.

Pre­dict­ing the lan­der's move­ments on the as­ter­oid thus means re­sort­ing to nu­mer­i­cal mod­els and sim­u­la­tions. There are nu­mer­ous mod­els for sim­u­lat­ing con­tact forces be­tween bod­ies. Sim­u­lat­ing the ef­fect of the mo­bil­ity mech­a­nism means de­ter­min­ing how MAS­COT's geom­e­try in­ter­sects with that of the ground at every point in time, and using the depth of the pen­e­tra­tion to cal­cu­late a con­tact force based on a mass-spring-damper model. It is nev­er­the­less dif­fi­cult to es­tab­lish pa­ra­me­ters re­quired by these mod­els such as stiff­ness or the damp­ing of the ground, as no data is avail­able re­lat­ing to the con­di­tions on as­ter­oids like Ryugu. Un­for­tu­nately, pre­cise move­ment in mi­cro­grav­ity is heav­ily de­pen­dent on such pa­ra­me­ters, while the lan­der's mo­bil­ity mech­a­nism must be able to cope with both bare rock and porous, peb­ble-cov­ered sur­faces.
 
The prob­lems faced by MAS­COT were solved by cal­cu­lat­ing dif­fer­ent mo­tion pro­files op­ti­mised for three dif­fer­ent types of ground sur­face. The Au­ton­omy Man­ager tests out each of these in suc­ces­sion by per­form­ing a ma­noeu­vre. If a mo­tion pro­file does not lead to the right out­come, an ac­tion suit­able for a dif­fer­ent type of ground sur­face is car­ried out. After each ma­noeu­vre, dis­tance sen­sors on the sides of the lan­der are used to check which side faces the ground. LEDs and pho­to­di­odes that mea­sure the light re­flected by the sur­round­ing ter­rain are mounted on all sides. The stronger the mea­sured sig­nal, the closer the sen­sor is to an ob­sta­cle or the ground. In ad­di­tion, MAS­COT has pho­to­cells that mea­sure the sun­light and fur­ther im­prove the at­ti­tude es­ti­ma­tion. These data can also be used to eval­u­ate the per­for­mance of the mo­bil­ity. Also, pic­tures are taken be­fore and after each ma­noeu­vre, which can also be used to de­duce the move­ment.

Nev­er­the­less, con­trolled re­lo­ca­tion and up­right­ing of a lan­der on a small body re­mains a chal­lenge. When re­search­ing com­pletely un­fa­mil­iar bod­ies, such as the as­ter­oid Ryugu, it is very dif­fi­cult to cre­ate a ro­bust mech­a­nism that can cope with the whole spec­trum of po­ten­tial en­vi­ron­men­tal con­di­tions. When MAS­COT sep­a­rates from the space probe Hayabusa2 on 3 Oc­to­ber, falls onto the as­ter­oid and be­gins work­ing there au­tonomously using its four sci­en­tific in­stru­ments, we will fi­nally know how it ac­tu­ally moves across the as­ter­oid's sur­face.

★ Hayabusa2 status (the week of 2018.09.24) ★

This week, the MINERVA-II1 rovers that landed on the asteroid last week sent images from the asteroid surface. No regolith was seen in these images, only a shocking scenery of large and small boulders. On the other hand, the scenes of sunlight on the asteroid and the rover hopping were both very beautiful and dynamic. Next week is the deployment of the MASCOT lander. The decent operation is always a nervous time and we want to deliver the lander steadily and carefully. (Regolith: fine grain sediments).

A German-built landing probe the size of a microwave oven carrying a camera and a suite of scientific instruments was closing in on asteroid Ryugu Tuesday, riding aboard Japan's Hayabusa 2 spacecraft to join two other robots deployed to the asteroid's surface last month.

The Mobile Asteroid Surface Scout, or MASCOT, is set to be released fr om the Japanese Hayabusa 2 mothership at 0158 GMT Wednesday (9:58 p.m. EDT Tuesday) for a free-fall final descent to the asteroid, with its landing velocity tempered by Ryugu's tenuous gravity field.

A few minutes later, MASCOT will reach Ryugu, and likely bounce several times before coming to a rest.

The battery-powered robot is set to land on the asteroid a week-and-a-half after a pair of Japanese landers -- each one even smaller than MASCOT -- touched down on Ryugu and beamed back the first-ever images fr om the surface of an asteroid.

MASCOT carries four instruments, and if it functions as designed, the lander will capture wide-angle color photos from Ryugu's craggy surface, collect measurements to determine if Ryugu's boulders emit a magnetic field, gather temperature and thermal information, and analyze the composition of the asteroid surface.
Launched in a carrying bay aboard Hayabusa 2 in December 2014, the MASCOT lander has been powered up and tested to ensure its instruments are ready for action. But the robot is heading into a hazardous environment on Ryugu, an asteroid that circles sun mostly between the orbits of Earth and Mars, and spans around 3,280 feet (1 kilometer) in diameter along its equator and approximately 2,880 feet (880 meters) from pole-to-pole.

The airless landing site sel ected for the European-made robot lies in Ryugu's southern hemisphere, with a temperature range between minus 81 degrees Fahrenheit (minus 63 degrees Celsius) to 145 degrees Fahrenheit (47 degrees Fahrenheit), comfortable enough for MASCOT to survive for at least 16 hours.

https://www.youtube.com/watch?v=8H4aZX_8hMA (https://www.youtube.com/watch?v=8H4aZX_8hMA)
But Hayabusa 2's reconnaissance of Ryugu since the mission's arrival at the asteroid in June has revealed a landscape strewn with boulders, introducing hurdles for hopping landers like MASCOT.

"MASCOT has to endure quite a bit on the surface," said Ralf Jaumann, principal investigator for the MASCOT lander at DLR, the German Aerospace Center. "Ryugu has very, very large boulders lying around. These will be like mountains for little MASCOT when it's on the surface. These boulders can be up to 40 meters (131 feet) tall."

Once it settles on the asteroid, MASCOT will use a mechanism to orient itself upright, then hop across Ryugu, exploring up to several different locations before its power supply runs out. MASCOT's lifetime is limited by the capacity of its battery, and it does not carry solar panels to recharge.

Scientists had to balance the needs of MASCOT's four instruments to pick a landing zone, which also had to be clear of sites wh ere Hayabusa 2 itself will attempt touch-and-go maneuvers in the coming months to collect samples for return to Earth.

"We are anxious to see whether MASCOT will slide out of its supporting frame smoothly, as we have planned and tested so extensively," said Tra-Mi Ho, MASCOT's project manager at DLR. "A smooth descent is crucial, otherwise MASCOT will bounce back up from the asteroid like a rubber ball due to the low gravitational pull, and be lost in space."

Scientists have calculated that Ryugu's gravity field is 80,000 times weaker than Earth's, making operations in the asteroid's vicinity more akin to a docking in space than a landing on a planet.

"We're entering a world that no one has ever seen before," said Christian Krause, MASCOT operations manager at DLR. "This is a single shot, everything has to work. We will simply be ejected. In principle, it desn't matter how we land on the surface."

MASCOT is a joint project between DLR and CNES, the German and French space agencies, and includes many of the same engineers and scientists who developed the larger Philae lander that flew to comet 67P/Churyumov-Gerasimenko with the European Space Agency's Rosetta spacecraft.

Philae landed on the comet in November 2014, less than a month before the launch of MASCOT, which officials have nicknamed Philae's "little brother."

MASCOT has a mass of around 22 pounds (10 kilograms) and measures 11.8 inches (30 centimeters) by 11.8 inches by 7.9 inches (20 centimeters).

"MASCOT is a small box about as big as a microwave oven," Jaumann said.

A team of controllers stationed at DLR's space center in Cologne, Germany, will monitor MASCOT during its exploration of Ryugu. They will decide whether to dispatch the lander to a different location, using a swing arm designed to generate momentum for hops in the asteroid's ultra-low gravity.

"In the final tests before the landing, we estimated that we would probably only let MASCOT perform one jump of less than 10 meters (32 feet), in order to preserve the battery life and ensure the optimal execution of the measurements and data transfer," Ho said. "What is more, recent images suggest that the surface of Ryugu has a rather uniform composition everywhere, so we do not need to perform big jumps."

In preparation for MASCOT's deployment, Hayabusa 2 started approaching asteroid Ryugu early Tuesday from a range of 12 miles (20 kilometers), heading for a position less than 200 feet (60 meters) from the asteroid, wh ere it will release the lander for its unpowered descent.

Officials from the Japan Aerospace Exploration Agency, which leads the Hayabusa 2 mission, released more pictures from a pair of mobile robots Thursday, several days after their landings on Ryugu.

The imagery reveals an uneven surface, with numerous rocks and boulders of various sizes. JAXA's update on the MINERVA-II-2 rovers last week indicated they were still functioning, with the help of solar panels to generate electricity.

Like MASCOT, the MINERVA-II-1 rovers carry internal mechanisms to hop across the asteroid, rather than wheels like the ones used on rovers driving on Mars. All of the landers communicate with Earth through the Hayabusa 2 mothership.

Ryugu is currently located 202 million miles (around 325 million kilometers) from Earth, and it takes approximately 16 minutes for a radio signal to cover the distance from Hayabusa 2 to Earth.

The low data rate link between Hayabusa 2 and MASCOT, coupled with the need to communicate with the Hayabusa 2 spacecraft itself, will mean scientists must wait a few days to receive measurements and photos fr om the lander. But controllers in Cologne, which will be linked with the Hayabusa 2 command center in Sagamihara, Japan, expect to receive confirmation Wednesday that MASCOT successfully deployed and reached the asteroid's surface.

"This is a completely different world," Jaumann said. "It's, very very far away, and we haven't seen anything like it before. When the first image comes in, and you see the surface, it could certainly look like a pile of rubble, but it is an extremely exciting pile of rubble. So I am really looking forward to seeing the first pictures."

ЦитатаThe small asteroid lander, MASCOT

MASCOT (Mobile Asteroid Surface Scout) is the asteroid lander jointly developed by DLR (German Aerospace Center) and CNES (French National Center for Space Studies). MASCOT is stored on the -Y-plane side of Hayabusa2 (this is the left-hand side surface when the high gain antenna is at the head and the ion engine is at the spacecraft back) and deployed fr om this position (see Figure 1).

MASCOT has the shape of a cuboid with dimensions 0.3 x 0.3 x 0.2m. The lander weighs about 10kg, and is a bit larger and heavier than the MINERVA-II1 rovers (diameter: 18cm, height: 7cm, weight: 1.1kg). (Figure 2).

On the top side of MASCOT is an antenna to communicate with the repeater (OME-E) of Hayabusa2, as with MINERVA-II1. A wide-angle camera (MASCAM) is mounted on the side to capture images of the lander's surrounding. An infrared spectroscopic microscope (MircOmega) sits on the bottom surface of MASCOT to investigate the composition and characteristics of the minerals on the surface of Ryugu. There is also a thermal radiometer (MARA) to measure the surface temperature and a magnetometer (MasMag) to measure any magnetic field.

MASCOT also has a hopping mechanism similar to that of MINERVA-II1. Using a motor to rotate a swing-arm within the lander, MASCOT can change its attitude or jump. Since MASCOT is designed to operate in the position wh ere the top antenna is directed upwards and the spectroscopic microscope faces downwards, this hopping mechanism can correct the attitude if the lander is in a different orientation once on the surface of Ryugu. MASCOT can also use the hop to move locations once; the lander does not hop multiple times like the MINERVA-II1 rovers.

For the landing site for MASCOT, a region in the southern hemisphere of Ryugu was selected (Figure 4). This location was selected based on criteria that ensured no overlap between the landing sites for the touchdown of Hayabusa2, MINERVA-II1 and MASCOT, the time to be able to communicate with Hayabusa2, the duration of sunlight exposure and expectation of scientifically meaningful exploration.

MASCOT does not use solar cells but is equipped with a lithium primary battery built into the lander. The duration of the battery is about 16 hours (about two rotations of Ryugu), allowing MASCOT to operate continuously for two Ryugu days after a successful separation. Operation of the lander will end when the battery runs out.

I'll do many things! I'll be there for two asteroid days & take lots of pictures. I've a very neat camera equipped with leds so I can take pics even if it's very dark! And maybe I'll even be able to see a boulder from the side!

ЦитатаLive coverage: MASCOT lander set to explore asteroid Ryugu
October 2, 2018 (https://spaceflightnow.com/2018/10/) | Stephen Clark (https://spaceflightnow.com/author/stephen-clark/)

Here's the latest view from Hayabusa 2's wide-angle navigation camera, showing asteroid Ryugu from a range of about 1.5 kilometers (1 mile). This image was captured at 2217 GMT (6:17 p.m. EDT).

(https://24liveblog.tradingfront.cn/event/2094405028392488612/20181002225725_837639.jpg) (https://photo.24liveblog.com/2094405028392488612/20181002225725_837639.jpg)

Hayabusa 2 is using its control thrusters and a laser navigation system to guide it toward Ryugu. Here's a timeline of the expected events to come tonight:
    [/li]
  • 2320 GMT (7:20 p.m. EDT): Hayabusa 2 begins communicating through JAXA's Usuda ground station in Japan.
  • 0030 GMT (8:30 p.m. EDT): Hayabusa 2 is 500 meters (1,640 feet) from Ryugu.
  • 0120 GMT (9:20 p.m. EDT): Hayabusa 2 is 250 meters (820 feet) from Ryugu.
  • 0151 GMT (9:51 p.m. EDT): This is the approximate time Hayabusa 2 reaches a target altitude for deployment of MASCOT around 60 meters (196 feet) from Ryugu. Hayabusa 2 will slow its approach from 10 centimeters per second to 3 centimeters per second (0.22 mph to 0.07 mph).
  • 0155:35 GMT (9:55:55 p.m. EDT): Hayabusa 2 shuts off its control thrusters and enters a free fall toward Ryugu, tugged by the asteroid's tenuous gravity.
  • 0158:15 GMT (9:58:15 p.m. EDT): MASCOT is released from Hayabusa 2.
It will take anywhere from 5 to 10 minutes for MASCOT to reach the asteroid's surface, and the robot is predicted to touch down at a velocity of around 20 centimeters per second, or less than 0.5 mph, seven times slower than a human's average walking pace.

The battery-powered robot will likely bounce across the asteroid a few times after landing, then settle into place to begin its 16-hour science campaign. MASCOT carries an uprighting mechanism to ensure its instruments and antennas are pointed in the right direction, and an internal swing arm is available to allow the rover to hop to different locations on the asteroid during its mission, which is limited by the craft's battery power supply.

The region marked in blue in this image is the target landing zone for MASCOT.

(https://24liveblog.tradingfront.cn/event/2094405028392488612/20181003001237_995300.jpg) (https://photo.24liveblog.com/2094405028392488612/20181003001237_995300.jpg)

There is some uncertainty over where MASCOT will end up after bouncing across the asteroid's surface, but the targeted touchdown location is situated in the southern hemisphere of Ryugu, at around 30 degrees south latitude.

The robot could end up anywhere within around 200 meters (656 feet) of the targeted landing site, according to the German space agency, DLR.

Engineers at DLR's lander control center in Cologne, Germany, have confirmed the MASCOT robot separated from Hayabusa 2 as intended. The lander's science instruments have all been activated, and the the craft's magnetometer detected a change in orientation, indicated MASCOT was tumbling toward asteroid Ryugu as designed, according to Ralf Jaumann, the lander's principal investigator at DLR.

Scientists celebrated the moment they received confirmation that MASCOT was safely away from Hayabusa 2. Data arrived in the control center verifying MASCOT's deployment at 0218 GMT (10:18 p.m. EDT), nearly 20 minutes after the lander's release.

More data from MASCOT is not expected to be transmitted back to Earth for at least a few hours, while Hayabusa 2 -- which acts as a signal relay between the lander and Earth -- climbs to a position 3 kilometers (1.9 miles) from the asteroid.

Японский зонд отправил к астероиду Рюгу еще одного робота-исследователя

Андроид оснащен широкоугольной камерой, микроскопом для изучения состава и характеристик пород с астероида, а также устройствами для измерения температуры и магнитного поля

ТОКИО, 3 октября. /ТАСС/. Робот-исследователь MASCOT в среду успешно отстыковался от японского зонда "Хаябуса-2", который находится возле астероида Рюгу в 280 млн км от Земли, и отправился к этому космическому телу, чтобы совершить на него посадку. Об этом сообщило (http://global.jaxa.jp/) Japan Aerospace Exploration Agency (JAXA).

Небольшой андроид совместной разработки ученых из Франции и Германии имеет кубическую форму с гранью 30 см и весит около 10 кг. Робот оснащен широкоугольной камерой, микроскопом для изучения состава и характеристик пород с астероида, а также устройствами для измерения температуры и магнитного поля. Его питание осуществляется за счет аккумуляторной батареи, рассчитанной на 16 часов работы.
В конце сентября JAXA уже осуществила успешную посадку на Рюгу двух роботов-исследователей, которые сделали ряд фотографий каменистого рельефа. MASCOT должен высадиться в другой части Рюгу и провести ее обследование, чтобы японские специалисты в конечном итоге смогли определиться с точкой приземления "Хаябусы-2".

Диаметр Рюгу, который находится между Землей и Марсом, около 900 м. "Хаябуса-2" был запущен к астероиду в декабре 2014 года с космодрома на японском острове Танэгасима. Ученые надеются найти на астероиде следы воды и органических веществ, что может помочь в разгадке тайны распространения жизни во Вселенной. Чтобы подтвердить или опровергнуть их теорию, зонд в общей сложности должен совершить три посадки на астероид, после чего к 2020 году вернется на Землю.

"Хаябуса-2" весит около 600 кг. Он представляет собой модифицированную версию первого "Сокола", который впервые в истории сумел доставить на Землю образцы материалов, собранные на поверхности иного, нежели Луна, космического объекта. В мае 2003 года он отправился к удаленному от Земли на 336,5 млн км астероиду Итокава. За семь лет зонд проделал самое продолжительное в истории человечества путешествие на расстояние в 6 млрд км.
Интересно, в чём оне андроида увидели??? Тем паче кубической формы...

ЦитатаMASCOT lands safely on asteroid Ryugu
03 October 2018

The near-Earth asteroid Ryugu, located approximately 300 million kilometres from Earth, has a new inhabitant: On 3 October 2018, the Mobile Asteroid Surface Scout (MASCOT) landed on the asteroid and began to work. The lander successfully separated from the Japanese Hayabusa2 space probe at 03:58 CEST. The 16 hours in which the lander will conduct measurements on the asteroid's surface have begun for the international team of engineers and scientists. The day before, the Japanese Space Agency's Hayabusa2 began its descent towards Ryugu. MASCOT was ejected at an altitude of 51 metres and descended in free fall - slower than an earthly pedestrian - to its destination, the asteroid. The relief about the successful separation and subsequent confirmation of the landing was clearly noticeable In the MASCOT Control Centre at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) as well as in the adjoining room: "It could not have gone better," explained MASCOT project manager Tra-Mi Ho from the DLR Institute of Space Systems. "From the lander's telemetry, we were able to see that it separated from the mothercraft, and made contact with the asteroid surface approximately 20 minutes later." The team is now in contact with the lander.
The moment of separation was one of the risks of the mission: If MASCOT had not successfully separated from Hayabusa2 as planned and often tested, the lander's team would hardly have had the opportunity to solve this problem. But everything went smoothly: Already during the descent on the asteroid, the camera switched MASCAM on and took 20 pictures, which are now stored on board the Japanese space probe. "The camera worked perfectly," says Ralf Jaumann, DLR planetary scientist and scientific director of the camera instrument. "The team's first images of the camera are therefore safe." The magnetometer team was also able to recognise in the data sent by MASCOT that the MASMAG instrument had switched on and performed measurements prior to the separation. "The measurements show the relatively weak field of the solar wind and the very strong magnetic disturbances caused by the spacecraft," explains Karl-Heinz Glaßmeier from the Technical University of Braunschweig. "At the moment of the separation, we expected a clear decrease of the interference field - and we were able to recognise this clearly."

MASCOT came to rest on the surface approximately 20 minutes after the separation. Now, the team is analysing the data that MASCOT is sending to Earth to understand the events occurring on the asteroid Ryugu. The lander should now be on the asteroid's surface, in the correct position thanks to its swing arm, and have started to conduct measurements independently. There are four instruments on board: a DLR camera and radiometer, an infrared spectrometer from the Institut d'Astrophysique Spatiale and a magnetometer from the TU Braunschweig. Once MASCOT has performed all planned measurements, it is expected to hop to another measuring location. This is the first time that scientists will receive data from different locations on an asteroid. "With MASCOT, we have the unique opportunity to study the Solar System's most primordial material directly on an asteroid," emphasises DLR planetary researcher Ralf Jaumann. With the data acquired by MASCOT and the samples that Hayabusa2 brings to Earth from Ryugu in 2020, scientists will not only learn more about asteroids, but more about the formation of the Solar System. "Asteroids are very primordial celestial bodies."
About the Hayabusa2 mission and MASCOT
Hayabusa2 is a Japanese space agency (Japan Aerospace Exploration Agency; JAXA) mission to the near-Earth asteroid Ryugu. The German-French lander MASCOT on board Hayabusa2 was developed by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and built in close cooperation with the French space agency CNES (Centre National d'Etudes Spatiales). DLR, the Institut d'Astrophysique Spatiale and the Technical University of Braunschweig have contributed the scientific experiments on board MASCOT. The MASCOT lander and its experiments are operated and controlled by DLR with support from CNES and in constant interaction with the Hayabusa2 team.

The DLR Institute of Space Systems in Bremen was responsible for developing and testing the lander together with CNES. The DLR Institute of Composite Structures and Adaptive Systems in Braunschweig was responsible for the stable structure of the lander. The DLR Robotics and Mechatronics Center in Oberpfaffenhofen developed the swing arm that allows MASCOT to hop on the asteroid. Das DLR Institute of Planetary Research in Berlin contributed the MASCAM camera and the MARA radiometer. The asteroid lander is monitored and operated from the MASCOT Control Center in the Microgravity User Support Center (MUSC) at the DLR site in Cologne.

Ground teams here in Cologne, Germany, have now confirmed that the MASCOT robot has successfully reached the surface of asteroid Ryugu.

"It could not have gone better," said Tra-Mi Ho from the DLR Institute of Space Systems, MASCOT's project manager. "From the lander's telemetry, we were able to see that it separated from the mothercraft, and made contact with the asteroid surface approximately 20 minutes later."

The robot is now conducting a pre-programmed, automated science sequence with its four instruments. Scientists have already confirmed MASCOT's camera has captured images following separation from Hayabusa 2 a few hours ago. Those images have been transmitted back to Hayabusa 2, which will relay telemetry and data between the lander and Earth.

HAYABUSA2/MASCOT - MISSION MASCOT LANDS SUCCESSFULLY ON RYUGU

After its release fr om Hayabusa2 today just before 04:00 and a short free-fall descent at an estimated speed of 15 cm/s, MASCOT (Mobile Asteroid surface SCOuT) successfully landed at the MA-9 site in the southern hemisphere of asteroid Ryugu, after bouncing several times on the particularly inhospitable surface that is strewn with rocks (according to pictures taken by Hayabusa2's camera from an altitude of 6 kilometres) and wh ere temperatures are not yet known.


The Japanese Hayabusa2 mission's French-German surface scout can now begin its science mission, a first in the history of space since it will be able to move about on the surface in short hops due to the asteroid's low gravity. With its four instruments, including the MicrOmega spectrometer developed by the IAS space astrophysics institute in Orsay with CNES oversight, MASCOT is set to analyse the mineral composition of grains in the asteroid's soil in an attempt to unlock its secrets at two sites just a few metres apart.

Scientists are keen to learn more about the properties and structure of near-Earth asteroids in order to gain new insights into how our solar system formed and how water and life emerged on Earth, and perhaps to determine solutions in the event of a risk of such an asteroid colliding with our planet.

For MASCOT, everything will play out during the 12 to 15 hours that its battery is designed to last immediately after the lander separates from Hayabusa2. This amazing space odyssey will then unfold as the science teams sift through the results of the lander's in-situ analyses.

MASCOT's ground team had to command the lander to use its internal swing arm mechanism to hop a short distance earlier than planned to ensure the probe's instruments were properly pointed, officials said.

"MASCOT is fine," said Tra-Mi Ho, the project manager at the German space agency, DLR. "Unfortunately, at the beginning it had a bit of a problem. We were landing in an unfavorable orientation.

"We solved the problem," she continued in a briefing a few minutes ago. "We have relocated a little bit earlier than we planned, and now MASCOT is on the second side."

The lander's lifetime is finite, and is expected to last around 16 hours from its initial landing, putting the likely end of the mission around 1800 GMT (2 p.m. EDT).

The spacecraft on the surface of Ryugu is currently in its second night. The asteroid rotates once every 7.6 hours, and MASCOT is battery-powered, so it can continue science data-gathering in sunlight and darkness.

Its cameras carry four LED lights -- three in visible wavelengths and one in infrared -- to illuminate nearby rocks to take pictures at night.

MASCOT is radioing its imagery and data up to the Japanese Hayabusa 2 spacecraft, which dropped it off just above the asteroid shortly before 0200 GMT (10 p.m. EDT) overnight. Hayabusa 2 will store the information and transmit it back to Earth in the coming days.

"The main challenge is that we would like to upload all the data which we have acquired," Ho said.

Японский зонд успешно высадил на астероид Рюгу нового робота для исследований

Зонд выпустил робота в свободное падение на расстоянии 70 м от астероида

ТОКИО, 3 октября. /ТАСС/. Новый робот-исследователь MASCOT, отсоединившийся (https://tass.ru/kosmos/5629961) ранее от японского зонда "Хаябуса-2" ("Сокол-2" ), совершил успешную посадку на астероид Рюгу в 280 млн км от Земли. Об этом сообщило (http://global.jaxa.jp/) в среду Японское агентство аэрокосмических исследований (JAXA).

Специально для этого зонд приблизился к космическому телу на расстояние около 70 м, после чего выпустил робота в свободное падение. Согласно полученной телеметрии, путь до астероида он преодолел за 20 минут и затем подал сигнал о посадке.

Небольшой аппарат совместной разработки ученых из Франции и Германии имеет кубическую форму с гранью 30 см и весит около 10 кг. Робот оснащен широкоугольной камерой, микроскопом для изучения состава и характеристик пород с астероида, а также устройствами для измерения температуры и магнитного поля. Его питание осуществляется за счет аккумуляторной батареи, рассчитанной на 16 часов работы.
В конце сентября JAXA уже осуществила успешную посадку на Рюгу двух роботов-исследователей, которые сделали ряд фотографий каменистого рельефа. MASCOT высадился в другой части Рюгу для обследования, чтобы японские специалисты в конечном итоге смогли определиться с точкой приземления "Хаябусы-2".

ЦитатаРовер MASCOT передал первые снимки после посадки на астероид Рюгю
13:36 03.10.2018 (обновлено: 13:40 03.10.2018)

МОСКВА, 3 окт - РИА Новости. Европейский астероидоход MASCOT успешно совершил посадку на астероид Рюгю и передал на Землю фотографии, которые он получал во время долгого спуска на поверхность этого небесного тела, сообщает сайт DLR (https://www.dlr.de/dlr/presse/en/desktopdefault.aspx/tabid-10172/213_read-30118/year-all/).

"Первые снимки, полученные ровером во время посадки, уже были успешно переданы на "Хаябусу"-2. Можно сказать, что MASCOT уже дал нам уникальную возможность всесторонне изучить образцы самой "чистой" первичной материи Солнечной системы, сохранившиеся со времен ее формирования", -- заявил Ральф Яуманн (Ralf Jaumann), научный руководитель миссии из Германского авиационно-космического центра (DLR).
Автоматическая станция "Хаябуса-2" была запущена в космос в начале декабря 2014 года для изучения, забора и возврата проб с астероида Рюгю. Как надеются ученые, она вернет на землю первые 100% "чистые" пробы первичной материи Солнечной системы.

Японский аппарат достиг цели в начале июня и начал длительную процедуру торможения и сближения с астероидом. Получив первые снимки и данные по устройству поверхности и недр Рюгю, зонд начал готовиться к процедуре по забору грунта.

Помимо этого, "Хаябуса-2" доставила к астероиду три спускаемых аппарата - два японских ровера MINERVA-II1, аналоги которых были отправлены к астероиду Итокава вместе с "Хаябусой-1", а также европейский аппарат MASCOT.

Роботы Rover-1A и Rover-1B были успешно сброшены на поверхность Рюгю в конце сентября. За последующие часы и дни они получили множество фотографий и собрали массу научных данных, которые сейчас обрабатываются специалистами JAXA.

ЦитатаРовер MASCOT успешно завершил основную миссию на астероиде Рюгю
11:06 04.10.2018

МОСКВА, 4 окт - РИА Новости. Европейский астероидоход MASCOT выполнил все научные цели миссии и собрал все возможные данные об устройстве астероида Рюгю и его химическом составе, которые рассчитывали получить ученые, передает DLR (https://twitter.com/DLR_en).

"Мы непрерывно вели эксперименты и замеры на протяжении 12 часов после посадки MASCOT на поверхность астероида. Робот успешно реализовал все научные задачи миссии, и наши батареи пока находятся в отличном состоянии", -- пишет официальный твиттер-канал миссии.

Автоматическая станция "Хаябуса-2" была запущена в космос в начале декабра 2014 года для изучения, забора и возврата проб с астероида Рюгю. Как надеются ученые, она вернет на землю первые 100% "чистые" пробы первичной материи Солнечной системы.

Японский аппарат достиг цели в начале июня и начал длительную процедуру торможения и сближения с астероидом. Получив первые снимки и данные по устройству поверхности и недр Рюгю, зонд начал готовиться к процедуре по забору грунта.

Помимо этого, "Хаябуса-2" доставила к астероиду три спускаемых аппарата - два японских ровера MINERVA-II1, аналоги которых были отправлены к астероиду Итокава вместе с "Хаябусой-1", а также европейский аппарат MASCOT.

Роботы Rover-1A и Rover-1B были успешно сброшены на поверхность Рюгю в конце сентября. За последующие часы и дни они получили множество фотографий и собрали массу научных данных, которые сейчас обрабатываются специалистами JAXA.

Сложная процедура по высадке их европейского "кузена" началась в понедельник, а успешная посадка состоялась утром в среду. Как отметили в DLR, спуск MASCOT был идеальным с точки зрения пилотов миссии и ее научной "половины", что позволило роботу почти сразу начать исследования и установить связь с "Хаябусой-2".

Единственная проблема, с которой столкнулись пилоты миссии, заключалась в том, что астероидоход совершил посадку на относительно темном участке поверхности Рюгю. Они решили эту проблему, "подвинув" MASCOT при помощи роботизированной руки ровера.

Снимки и данные, собранные роботом, уже были переданы на "Хаябусу-2", и в ближайшее время они будут отправлены на Землю. "Хаябуса-2" пока находится на "промежуточной" высоте, на расстоянии в 3 километра от поверхности астероида, что позволяет ей следить за перемещениями ровера и поддерживать связь с ним.

ЦитатаКамни или кратеры: японский зонд прислал фото астероида с оптической иллюзией
Модуль MASCOT Lander, являющийся частью японского космического зонда "Хаябуса-2", прислал снимок астероида Рюгу, на котором некоторые видят камни, а некоторые кратеры.
Снимки поверхности Рюгу - околоземного астероида из группы Аполлона - были опубликованы 3 октября. С тех пор в интернете идут споры, что на них изображено, а снимок уже прозвали космическим "желто-голубым" платьем.
Японские исследователи пока не рассказали, что на самом деле на фото, но пользователи интернета уже нашли вероятный ответ на этот вопрос: судя по теням, это все же камни.

Этот эффект уже несколько раз упоминался на форуме.
Чтобы увидеть камни, лучше сосредоточиться на правом нижнем углу изображения, а чтобы "переключиться на "кратеры" - посмотреть на экран под острым углом.
И всё-таки - не камни! Иначе - массаракш - "мир наизнанку" (c) - тень от зонда на ярком фоне должна попадать в глубокую воронку. Особенно очевидно на фото четырьмя постами выше #574

ЦитатаThree hops in three asteroid days - MASCOT successfully completes the exploration of the surface of asteroid Ryugu

05 October 2018
    [/li]
  • As planned, MASCOT was able to acquire data about the composition and texture of the asteroid at several locations.
  • Before the battery depleted, the lander sent all scientific data to the Hayabusa2 mothercraft.
  • New images from MASCOT's landing on asteroid Ryugu were presented by DLR, JAXA and CNES today at the International Astronautical Congress (IAC).
  • Focus: Space, exploration
It was a day full of exciting moments and a happy team of scientists and engineers: late in the afternoon of 3 October 2018, the German-French lander MASCOT completed its historic exploration of the surface of the asteroid Ryugu at 21:04 CEST, as its battery ran out. On-asteroid operations were originally scheduled to last 16 hours after separation from the Japanese mothercraft Hayabusa2. But in the end, the battery lasted more than 17 hours. Upon landing in the early morning and subsequently relocating using the built-in swing arm, all instruments collected detailed data on the composition and nature of the asteroid. The on-board camera provided pictures of the landing, hopping manoeuvres and various locations on the surface.

For MASCOT, the Sun set three times on Ryugu. The lander was commanded and controlled from the MASCOT Control Centre at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) in Cologne, in the presence of teams of scientists from Japan, France and Germany. All scientific data was transferred to the mother probe according to plan.

"With MASCOT, it has been possible to, for the first time, explore the surface of an asteroid directly on site so extensively," says Hansjörg Dittus, DLR Executive Board Member for Space Research and Technology. "A mission like this can only be done working in close cooperation with international partners - bringing together all their expertise and commitment." With MASCOT, DLR has been working closely with the Japanese space agency JAXA and the French space agency CNES.

Jumps and a mini-move
MASCOT landed safely on Ryugu in the early morning of 3 October 2018. "After a first automated reorientation hop, it ended up in an unfavourable position. With another manually commanded hopping manoeuvre, we were able to place MASCOT in another favourable position thanks to the very precisely controlled swing arm," says MASCOT operations manager Christian Krause from DLR. From that position, MASCOT completed a complete measurement sequence with all instruments over one asteroid day and an asteroid night. "Later, we were able to continue the activities on Ryugu with a special manoeuvre," adds Ralf Jaumann, DLR planetary scientist and scientific director of MASCOT. "With a 'mini-move' we recorded image sequences that will be used to generate stereo images of the surface once they have been analysed."

During the first manoeuvres, MASCOT moved several metres to the next measuring point. Finally, and seeing that the lander still had battery power left, the researchers dared to make a bigger jump. All in all, MASCOT explored Ryugu for three asteroid days and two asteroid nights. A day-night cycle on Ryugu lasts about 7 hours and 36 minutes. At 21:04 CEST, communications with Hayabusa2 were interrupted, because of the radio shadow entering with each asteroid rotation. Hayabusa2 is now returning to its home position, at an altitude of 20 kilometres above the asteroid's surface.

In addition to the images acquired by the DLR camera MASCAM, a DLR radiometer, a magnetometer from TU Braunschweig and a spectrometer from the Institut d'Astrophysique Spatiale provided a variety of measurements on the temperature, magnetic properties and the composition of the near-Earth asteroid Ryugu.
Waiting for the scientific data
MASCOT is now a silent inhabitant of Ryugu. "The evaluation of the valuable data has just begun," says MASCOT project manager Tra-Mi Ho from the DLR Institute of Space Systems. "We will learn a lot about the past of the Solar System and the importance of near-Earth asteroids like Ryugu. Today, I look forward to the scientific publications that will result from MASCOT and the remarkable Hayabusa2 mission of our Japanese partners. "Hayabusa2 played a crucial role in the success of MASCOT. The Japanese probe brought the lander to the asteroid. Thanks to precise planning and control, the communication links to the lander could be optimally used for data transmission, so that the first pictures were received on the very day of landing. The remaining scientific data, which was transmitted to Hayabusa2, will be sent to Earth in the coming days.
About the Hayabusa2 mission and MASCOT
Hayabusa2 is a Japanese space agency (Japan Aerospace Exploration Agency; JAXA) mission to the near-Earth asteroid Ryugu. The German-French lander MASCOT on board Hayabusa2 was developed by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and built in close cooperation with the French space agency CNES (Centre National d'Etudes Spatiales). DLR, the Institut d'Astrophysique Spatiale and the Technical University of Braunschweig have contributed the scientific experiments on board MASCOT. The MASCOT lander and its experiments are operated and controlled by DLR with support from CNES and in constant interaction with the Hayabusa2 team.

The DLR Institute of Space Systems in Bremen was responsible for developing and testing the lander together with CNES. The DLR Institute of Composite Structures and Adaptive Systems in Braunschweig was responsible for the stable structure of the lander. The DLR Robotics and Mechatronics Center in Oberpfaffenhofen developed the swing arm that allows MASCOT to hop on the asteroid. Das DLR Institute of Planetary Research in Berlin contributed the MASCAM camera and the MARA radiometer. The asteroid lander is monitored and operated from the MASCOT Control Center in the Microgravity User Support Center (MUSC) at the DLR site in Cologne.

MASCOT worked longer and delivered more data than expected
(https://www.dlr.de/dlr/en/Portaldata/1/Resources/portal_bilder/2018/2018_4/05Bild_16zu9_MASCOT_LastOrder_l.jpg)

From the evening of 2 October 2018, 24 hours of absolute tension prevailed in the MASCOT Control Centre at the DLR site in Cologne: Approximately 40 scientists followed the events taking place 300 million kilometres from Earth - even before the applause-filled separation of the German-French landing module on 3 October 2018 at 03:58 CEST [please check!] from the Japanese space probe Hayabusa2, the landing on the asteroid Ryugu six minutes later, and the end of the mission at 21.04 hours CEST. MASCOT fulfilled and exceeded the expectations of the lander, as the batteries delivered more power than planned. Lasting 17 hours, this made it possible to conduct experiments for one additional hour. All four instruments on-board MASCOT did far more than the planned measurements and recordings. In the foreground of the image, we can see MASCOT Project Manager Tra-Mi Ho from the DLR Institute of Space Systems in Bremen at the MASCOT Control Centre of the DLR Microgravity User Support Centre in Cologne, relieved by the almost smooth running of this extraordinary mission. In the background, Ralf Jaumann, Scientific Director of MASCOT, presents some of the 120 images taken with the DLR camera MASCAM of the DLR Institute of Planetary Research in Berlin.

Ryugu's surface - just before MASCOT's first contact
(https://www.dlr.de/dlr/en/Portaldata/1/Resources/portal_bilder/2018/2018_4/22GID111_16_16-9_l.jpg)

DLR's MASCAM camera took 20 images during MASCOT's 20-minute fall to Ryugu, following its separation from Hayabusa2, which took place at 51 metres above the asteroid's surface. This image shows the landscape near the first touchdown location on Ryugu from a height of about 25 to 10 metres. Light reflections on the frame structure or the camera body scatter into the field of vision of the MASCAM (bottom right) as a result of the backlit light of the Sun shining on Ryugu. Ryugu has a coarse textured, extremely dark surface that reflects only about 2.5 percent of the incoming sunlight. The rugged area shown here is about as dark as asphalt. Details of the terrain structures are visible in the MASCAM images thanks to the photosensitive semiconductor elements of the 1000 by 1000 pixel CMOS (complementary metal-oxide semiconductor) camera sensor, whose dynamics enhance even the weakest light signals and deliver scientifically usable image data.

The surface of Ryugus from a few metres
(https://www.dlr.de/dlr/en/Portaldata/1/Resources/portal_bilder/2018/2018_4/ryugu-2_l.jpg)

The approximately 20 images acquired with the MASCAM camera on the MASCOT lander during the descent show an extremely rugged surface covered with numerous angular rocks. Ryugu, a four-and-a-half billion year-old C-type asteroid has shown the scientists something they had not expected, even though more than a dozen asteroids have been explored up close by space probes. On this close-up, there are no areas covered with dust - the regolith that results from the fragmentation of rocks due to exposure to micrometeorite impacts and high-energy cosmic particles over billions of years. The image from the turbulent rotating MASCOT lander was taken at a height of about 10 to 20 metres.

МОСКВА, 5 окт - РИА Новости. Европейский ровер MASCOT исчерпал запасы энергии и завершил работу на поверхности астероида Рюгю, выдержав примерно трое "суток" непрерывной работы или 17 земных часов, сообщает DLR.

"Мы только начали изучать данные, которые собрал MASCOT. Я ожидаю, что мы узнаем много нового о прошлом Солнечной системы и поймем, насколько важны Рюгю и другие околоземные астероиды для изучения тайн нашей планеты", -- заявил Тра-ми Хо (Tra-Mi Ho), руководитель миссии MASCOT в Германском авиационно-космическом центре(DLR).
Автоматическая станция "Хаябуса-2" была запущена в космос в начале декабря 2014 года для изучения, забора и возврата проб с астероида Рюгю. Как надеются ученые, она вернет на землю первые 100% "чистые" образцы первичной материи Солнечной системы.

Японский аппарат достиг цели в начале июня и начал длительную процедуру торможения и сближения с астероидом. Получив первые снимки и данные по устройству поверхности и недр Рюгю, зонд начал готовиться к процедуре по забору грунта.

Помимо этого, "Хаябуса-2" доставила к астероиду три спускаемых аппарата - два японских ровера MINERVA-II1, аналоги которых были отправлены к астероиду Итокава вместе с "Хаябусой-1", а также европейский аппарат MASCOT.

Роботы Rover-1A и Rover-1B были успешно сброшены на поверхность Рюгю в конце сентября. За последующие часы и дни они получили множество фотографий и собрали массу научных данных, которые сейчас обрабатываются специалистами JAXA.

Фотография поверхности астероида Рюгю, полученная ровером MASCOT

Сложная процедура по высадке их европейского "кузена" началась в понедельник, а успешная посадка состоялась утром в среду. Как отметили в DLR, спуск MASCOT был идеальным с точки зрения пилотов миссии и ее научной "половины", что позволило роботу почти сразу начать исследования и установить связь с "Хаябусой-2".

Вчера робот успешно решил все научные задачи миссии, собрав все необходимые данные и снимки для раскрытия тайн геологии Рюгю и изучения образцов первичной материи Солнечной системы. Потратив на это примерно одни астероидные "сутки", MASCOT проработал на поверхности астероида еще два дня, совершив несколько прыжков по его поверхности и собрав несколько дополнительных наборов данных.

Как отмечают планетологи, они изначально рассчитывали на то, что ровер проработает дольше основного срока миссии. По этой причине они разработали несколько "расширенных" программ работы, однако и их не хватило - MASCOT проработал час дольше, чем ожидали пилоты миссии, и собрал массу "бонусной" информации.

Часть этих данных, как отмечают ученые, уже была передана на Землю, а более "объемные" фотографии и замеры инструментов будут отправлены "Хаябусой-2" после того, как зонд вернется на более высокую орбиту.

ЦитатаHayabusa2 successfully images MASCOT separating fr om the spacecraft!

The small asteroid lander, MASCOT, that was developed in Germany and France, was successfully separated fr om the Hayabusa2 spacecraft on October 3 and delivered safely to the surface of Ryugu. After landing, MASCOT acquired scientific data on the asteroid surface, which was transmitted to the MASCOT team via the spacecraft. Scientific analysis of this data is expected to be performed by the MASCOT team from now onwards.

From the Hayabusa2 spacecraft, we attempted to capture the separated MASCOT using the three optical navigation cameras (ONC-T, ONC-W1, ONC-W2). When the image data was received from the spacecraft, we could confirm that MASCOT appears in images photographed with the ONC-W1 and ONC-W2.

Figure 1 shows MASCOT photographed by the ONC-W2 immediately after separation. MASCOT was captured on three consecutively shot images, making a short animated movie. The image capture time is between 10:57:54 JST - 10:58:14 JST on October 3. Since separation time itself was at 10:57:20 JST, these images were captured immediately after separation. The ONC-W2 is a camera attached to the side of the spacecraft and is shooting diagonally downward from Hayabusa2. This gives an image showing MASCOT descending with the surface of Ryugu in the background. MASCOT is especially clear in the third image.

Figure 2 shows the image of MASCOT photographed with the ONC-W1. This picture was captured at 10:59:40 JST on October 3, 2 minutes and 20 seconds after the lander separated from the spacecraft. The ONC-W1 is attached to the bottom of the spacecraft, so the view is directly below Hayabusa2. At this point, the spacecraft is rising slowly. MASCOT is the white dot and has not yet landed on the asteroid surface, so the lander casts a shadow that creates a black dot on the surface of Ryugu. Beside it, is the shadow of Hayabusa2.

If you enlarge the white dot of MASCOT in Figure 2, it appears as if there is a white round dot inside a black square. It seems that it is the base (bottom) of MASCOT that is visible. Figure 3 is a picture of the base of MASCOT. Comparing with the enlarged picture of MASCOT in Figure 2, the shining white dot is thought to be the antenna.

ЦитатаMASCOT lander hops around asteroid, exceeding scientists' expectations

BREMEN and COLOGNE, Germany -- The MASCOT lander released fr om Japan's Hayabusa 2 spacecraft this week made three hops to different locations on asteroid Ryugu before draining its battery, outliving its design life and sending back data from all four of its instruments, according to German and French officials who developed the surface robot.

The tiny lander, no bigger than a microwave oven, released from the Hayabusa 2 spacecraft at 0157:20 GMT Wednesday (9:57:20 p.m. EDT Tuesday) as the Japanese mothership maneuvered to a point just 167 feet (51 meters) from Ryugu.

Six minutes later, the tumbling lander made first contact with the asteroid's surface -- at 0203 GMT (10:03 p.m. EDT) -- and bounced several times, as intended, before coming to a stop and kicking off an pre-programmed automated science campaign.

The Mobile Surface Asteroid Scout lasted more than 17 hours, exceeding projections going into the mission. The lander's lifetime was limited by the capacity of its lithium battery, and designers did not put solar panels on the craft to save weight and money.
"In our estimation, we thought we'd last 12 hours if it was a success, maybe 15 or 16 hours if we were really over the top," said Aurélie Moussi, MASCOT's project manager at CNES, the French space agency, which provided the battery. "We lasted 17 hours. That's amazing."

"In our best dreams, we did not expect so much joy," Moussi said.

Some of the instruments on MASCOT, along with many members of its ground team, come from the Philae mission, which landed on comet 67P/Churyumov-Gerasimenko in 2014 after separating from the European Space Agency's Rosetta comet orbiter.

Like Philae, MASCOT bounced around the surface of its new home. But Philae carried anchoring gear and other landing aids to try and prevent such movements, while the simplified MASCOT lander carried no such equipment.

Nevertheless, Philae gathered images and other scientific data throughout its sojourn around the comet.

"We used (battery) cells from the exact same batch as Philae," Moussi said Friday in a presentation at the International Astronautical Congress in Bremen, Germany. "It seems this batch is really good."

The Hayabusa 2 spacecraft, managed by the Japan Aerospace Exploration Agency, put the MASCOT lander on course for a landing zone in Ryugu's southern hemisphere. Once on the surface, MASCOT had an internal swing arm that could move like a pendulum, allowing it to generate momentum and hop to different locations on the asteroid, which measures around 0.6 miles (1 kilometer) in diameter, and has a gravity field 80,000 times weaker than Earth's.

Ryugu circles the sun on a path primarily between the orbits of Earth and Mars. The asteroid briefly dips inside the orbit of Earth on each trip around the sun, making Ryugu a potentially hazardous asteroid that could eventually pose an impact threat to our planet.

Stephan Ulamec, MASCOT's payload manager at DLR, the German space agency, praised the Hayabusa 2 spacecraft for the tricky descent maneuvers toward an asteroid more than 200 million miles (about 325 million kilometers) from Earth.

"The Hayabusa 2 spacecraft worked so well, like clockwork," he said. "We're tempted to assume all of this is easy, and trivial because it worked so well. It's not at all."

"Our part was comparably easy," joked Ulamec, who was project manager on the Philae comet lander. "We got dumped. We fell down and landed, and the one tricky part was we had to upright and operate for the time which the primary battery allowed."

Engineers at DLR's lander control center in Cologne, Germany, detected the robot was facing the wrong way once it settled on the surface. That forced controllers to abandon the original science plan and send pre-packaged contingency commands to MASCOT, routed through the Hayabusa 2 control center in Sagamihara, Japan, to roll over using its on-board uprighting mechanism.

"After this very first touchdown, we noticed fairly quickly the lander was upside down," Ulamec said.

The rollover worked as designed, and the robot moved around 1 or 2 meters (3 to 6 feet) and all four instruments started collecting data from the asteroid's surface, Ulamec said.

Ryugu rotates once on its axis every 7 hours, 36 minutes, so MASCOT experienced three sunsets before draining its battery on the asteroid.

The lander collected measurements during day and night. Its camera carried four light diodes to illuminate nearby rocks in red, green, blue and infrared light. A radiometer instrument measured temperatures of Ryugu's surface material during a full day-night cycle, data that could help scientists learn about the physical properties of asteroid rocks and dust, giving new insights to future missions that will interact with asteroid surfaces, according to Matthias Grott, principal investigator for MASCOT's radiometer at DLR.

"What we've learned so far from the pictures is it looks like the surface is more consolidated rocks overlaid by a thin layer of particulate material," Grott said.

MASCOT's magnetometer measured the lander's spin as it descended to the asteroid, helping confirm its successful deployment from Hayabusa 2 and telling controllers about the robot's movement across the surface. The instrument was also designed to search for any remnant magnetic field on the asteroid.

During MASCOT's second three-and-a-half hour day on asteroid Ryugu, the lander executed a small move to put surface material within view of a tiny microscope designed to unravel the mineral make-up of the asteroid's rocks, seeking the chemical signatures of carbon and molecules that may have once interacted with water.

"For the first time, we're trying to measure the composition of an asteroid's carbon-rich material," said Jean-Pierre Bibring, lead scientist on MASCOT's MicrOmega spectrometer. "To do so, we built an instrument that's supposed to be in contact (with the surface)."

As always, in exploration you never know wh ere you're going," said Bibring, a scientist at Institut d'Astrophysique Spatiale in Orsay, France. "We landed there for the first time trying to measure the composition, and of course, we discovered a lot of things we didn't plan to."

"Later, we were able to continue the activities on Ryugu with a special maneuver," said Ralf Jaumann, DLR planetary scientist and scientific director of MASCOT. "With a 'mini-move' we recorded image sequences that will be used to generate stereo images of the surface once they have been analyzed."

MASCOT made a final leap before its mission ended to travel several meters to another site, and controllers lost their radio link with the lander at 1904 GMT (3:04 p.m. EDT) Wednesday as it went into its third night on the asteroid.

After it deployed MASCOT, Hayabusa 2 climbed to a position nearly 2 miles (3 kilometers) from the asteroid to relay data between Earth and the lander. But Hayabusa 2, which had to stay in sunlight to generate electrical power, was unable to contact MASCOT when its landing zone rotated out of the mothership's field-of-view and into night.

By the time MASCOT re-emerged into daylight, Hayabusa 2 heard no signal from the lander.

"The evaluation of the valuable data has just begun," said Tra-Mi Ho, MASCOT's project manager at the DLR Institute of Space Systems. "We will learn a lot about the past of the solar system and the importance of near-Earth asteroids like Ryugu."

MASCOT's exploration of Ryugu came less than two weeks after Hayabusa 2 released two Japanese-built robots -- each even smaller than MASCOT -- that bounced around the asteroid's surface.

The landers deployed by Hayabusa 2 were not the first to touch down on an asteroid and return data -- that distinction goes to NASA's NEAR-Shoemaker probe that landed on asteroid Eros in 2001. But they are the first to return images from an asteroid's surface, and the first missions to move to different locations on an asteroid.

MASCOT was developed and built for around 25 million euros ($29 million), Ulamec said.

"With MASCOT, it has been possible to, for the first time, explore the surface of an asteroid directly on site so extensively," says Hansjörg Dittus, DLR executive board ember for space research and technology. "A mission like this can only be done working in close cooperation with international partners - bringing together all their expertise and commitment."

Hayabusa 2's mission is far from over.

The $260 million probe's primary objective is to collect up to three samples from Ryugu and bring the back to Earth. The first sampling attempt is scheduled as soon as the end of October, followed by two more next year.

Hayabusa 2 will also release one more robot to hop around the asteroid next year, before departing Ryugu in time to drop its sample return capsule for a re-entry and landing in Australia in December 2020.

ЦитатаNumerous boulders, many rocks, no dust: MASCOT's zigzag course across the asteroid Ryugu
12 October 2018
    [/li]
  • The scientists were able to follow the path that MASCOT travelled on the surface of Ryugu on the basis of images and data fr om the mother probe Hayabusa2 and the lander.

  • Never before in the history of space has a body of the Solar System been explored in this way.

  • Focus: Space, exploration
Six minutes of free fall, a gentle impact on the asteroid and then 11 minutes of rebounding until coming to rest. That is how, in the early hours of 3 October 2018, the journey of the MASCOT asteroid lander began on Asteroid Ryugu - a land full of wonder, mystery and challenges. Some 17 hours of scientific exploration followed this first 'stroll' on the almost 900-metre diameter asteroid. The lander was commanded and controlled from the MASCOT Control Centre at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) site in Cologne in the presence of scientific teams from Germany, France and Japan. MASCOT surpassed all expectations and performed its four experiments at several locations on the asteroid. Never before in the history of spaceflight has a Solar System body been explored in this way. It has now been possible to precisely trace MASCOT's path on Ryugu's surface on the basis of image data from the Japanese Hayabusa2 space probe and the lander's images and data.

"This success was possible thanks to state-of-the-art robotic technology, long-term planning and intensive international cooperation between the scientists and engineers of the three space nations Japan, France and Germany," says Hansjörg Dittus, DLR Executive Board Member for Space Research and Technology about this milestone in Solar System exploration. "We are proud of how MASCOT was able to master its way across the asteroid Ryugu over boulders and rocks and send so much data about its composition back to Earth," says DLR Chair Pascale Ehrenfreund.

MASCOT had no propulsion system and landed in free fall. Six minutes after separating from Hayabusa2, and following the end of a ballistic trajectory, the landing module made its first contact with asteroid Ryugu (https://www.dlr.de/dlr/en/desktopdefault.aspx/tabid-10081/151_read-30138/#/gallery/32253). On the surface, MASCOT moved through the activation of a tungsten swing arm accelerated and decelerated by a motor. This made it possible for MASCOT to be repositioned to the 'correct' side or even perform hops across the asteroid's surface. The gravitational attraction on Ryugu is just one 66,500th of the Earth's, so the little momentum provided was enough: a technological innovation for an unusual form of mobility on an asteroid surface used for the first time in the history of space travel as part of the Hayabusa2 mission.

Through a rock garden full of rough boulders and no flat surfaces
To reconstruct MASCOT's path across the surface of Ryugu, the cameras aboard the Hayabusa2 mother probe were aimed at the asteroid. The Optical Navigation Cameras (ONC) captured the lander's free fall in several images, detected its shadow on the ground during the flight phase, and finally identified MASCOT directly on the surface in several images. The pattern of the countless boulders distributed on the surface could also be seen in the direction of the respective horizon in oblique photographs of the lander's DLR MASCAM camera. The combination of this information unlocked the unique path traced by the lander.

After the first impact, MASCOT smoothly bounced off a large block, touched the ground about eight times, and then found itself in a resting position unfavourable for the measurements. After commanding and executing a specially prepared correction manoeuvre, MASCOT came to a second halt. The exact location of this second position is still being determined. There, the lander completed detailed measurements during one asteroid day and night. This was followed by a small 'mini-move' to provide the MicrOmega spectrometer with even better conditions for measuring the composition of the asteroid material.

Finally, MASCOT was set in motion one last time for a bigger jump. At the last location it carried out some more measurements before the third night on the asteroid began, and contact with Hayabusa2 was lost as the spaceship had moved out of line of sight. The last signal from MASCOT reached the mother probe at 21:04 CEST. The mission was over. "We were expecting less than 16 hours of battery life because of the cold night, says MASCOT project manager Tra-Mi Ho from the DLR Institute of Space Systems. "After all, we were able to operate MASCOT for more than one extra hour, even until the radio shadow began, which was a great success." During the mission, the team named MASCOT's landing site (MA-9) 'Alice's Wonderland', after the eponymous book by Lewis Carroll (1832-1898).
A true wonderland
Having reconstructed the events that took place on asteroid Ryugu, the scientists are now busy analysing the first results from the acquired data and images. "What we saw from a distance already gave us an idea of what it might look like on the surface," reports Ralf Jaumann from the DLR Institute of Planetary Research and scientific director of the MASCOT mission. "In fact, it is even crazier on the surface than expected. Everything is covered in rough blocks and strewn with boulders. How compact these blocks are and what they are composed of, we still do not know. But what was most surprising was that large accumulations of fine material are nowhere to be found - and we did not expect that. We have to investigate this in the next few weeks, because the cosmic weathering would actually have had to produce fine material," continues Jaumann.

"MASCOT has delivered exactly what we expected: an 'extension' of the space probe on the surface of Ryugu and direct measurements on site," says Tra-Mi Ho. Now there are measurements across the entire spectrum, from telescope light curves from Earth to remote sensing with Hayabusa2 through to the microscopic findings of MASCOT. "This will be of enormous importance for the characterisation of this class of asteroids," emphasises Jaumann.

Ryugu is a C-type asteroid - a carbon-rich representative of the oldest bodies of the four-and-a-half-billion year-old Solar System. It is a 'primordial' building block of planet formation, and one of 17,000 known Near-Earth asteroids.

On Earth, there are meteorites with a composition that could be similar to Ryugu's, which are found in the Murchison Range, Australia. However, Matthias Grott from the DLR Institute of Planetary Research and responsible for the radiometer experiment MARA is skeptical as to whether these meteorites are actually representative of Ryugu in terms of their physical properties: "Meteorites such as those found in Murchison are rather massive. However, our MARA data suggests the material on Ryugu is slightly more porous. The investigations are just beginning, but it is plausible to assume that small fragments of Ryugu would not survive the entry into the Earth's atmosphere intact."
About the Hayabusa2 mission and MASCOT
Hayabusa2 is a Japanese space agency (Japan Aerospace Exploration Agency; JAXA) mission to the near-Earth asteroid Ryugu. The German-French lander MASCOT on board Hayabusa2 was developed by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and built in close cooperation with the French space agency CNES (Centre National d'Etudes Spatiales). DLR, the Institut d'Astrophysique Spatiale and the Technical University of Braunschweig have contributed the scientific experiments on board MASCOT. The MASCOT lander and its experiments are operated and controlled by DLR with support from CNES and in constant interaction with the Hayabusa2 team.

The DLR Institute of Space Systems in Bremen was responsible for developing and testing the lander together with CNES. The DLR Institute of Composite Structures and Adaptive Systems in Braunschweig was responsible for the stable structure of the lander. The DLR Robotics and Mechatronics Center in Oberpfaffenhofen developed the swing arm that allows MASCOT to hop on the asteroid. Das DLR Institute of Planetary Research in Berlin contributed the MASCAM camera and the MARA radiometer. The asteroid lander is monitored and operated from the MASCOT Control Center in the Microgravity User Support Center (MUSC) at the DLR site in Cologne.
MASCOT's 17 hours and 7 minutes on Ryugu
[TH]Time (CEST)[/TH][TH]Event[/TH]
03:57:21At an altitude of 51 metres above asteroid Ryugu, MASCOT is pushed out of the Hayabusa2 supporting frame by means of a spring mechanism behind a push-off plate at about 4 centimetres per second and starts to descend to Ryugu without control of its ground station.
04:03Approximately six minutes later, MASCOT touches down on Ryugu, making contact with a block of rocks about three to four metres high. The Optical Navigation Camera (ONC) from Hayabusa2 records the process in high-resolution images. At the same time, DLR's MASCAM acquires 20 images of the asteroid during the descent. MASCOT lands on the designated landing site MA-9 (Alice's Wonderland). It is located at about 300 degrees east and 30 degrees south.
Around 04:34
First location
After another approximately. 31 minutes and several contacts with the surface, MASCOT reaches its first resting position. It is asteroid day at the landing site and the surface measurements start.
Around 06:30At the DLR Control Centre in Cologne it is recognised that MASCOT is lying on an unfavourable side and thus cannot carry out its planned experiments. All systems and experiments are operating as intended.
Around 09:20An unscheduled command from the Earth is sent to Hayabusa2 and from there to MASCOT to activate the swing arm to turn the lander into its intended position for the experiments. The command time to Ryugu, which is about 300 million kilometres away, is about 18 minutes one way.
Around 09:52MASCOT has completed its first day-and-night cycle. The second day on Ryugu begins.
Around. 10:30
Second location
The manoeuvre has brought the desired result. MASCOT is in the right position, is now operational and automatically starts to perform its four experiments again.
Around 12:51The second daylight phase on Ryugu is slowly coming to an end, and MASCOT turns with Ryugu into its second asteroid night.
Around 17:28MASCOT's third day on Ryugu begins.
Around 18:29
Third location
MASCOT successfully executes a mini-move. This manoeuvre was commanded by the operations team in Cologne to optimise the position of the sensors of the experiments. Further scientific investigations are carried out.
Around 20:04 Fourth locationThe last jump is commanded to MASCOT and the lander goes into the End of Life phase. Further scientific investigations are carried out.
21:04It is the end of the third day for MASCOT on Ryugu. In the meantime, more than 16 hours have passed - the lander's expected maximum battery life. Contrary to the calculations, the battery still provides some power before the contact with MASCOT breaks off by the entry of a radio shadow and the upcoming night. Instead of 16 hours, the experiments were able to work for 17 hours and 7 minutes.

MASCOT's approach to Ryugu and its path across the surface
(https://www.dlr.de/dlr/en/Portaldata/1/Resources/portal_bilder/2018/2018_4/MASCOT_PM_Uebersicht_l.jpg)
After MASCOT had separated from its mothercraft, Hayabusa2's ONC (Optical Navigation Camera) recording system, with its three cameras, began following MASCOT's descent to the asteroid Ryugu from a height of 51 metres. The image section is oriented to the north, and the area shown is located at approximately 300 degrees east and 30 degrees south. Hayabusa2's shadow can be seen on the lower right. At the time of the separation, it was about noon on Ryugu and the Sun was behind Hayabusa2 - the shadow is about six by 4.5 metres. The points indicate the times at which Hayabusa2 acquired images of MASCOT. The times are in UTC (Coordinated Universal Time, CEST minus two hours), the first image was acquired at 01:59 and 40 seconds UTC (03:59:40 CEST). The yellow line indicates the locations at which MASCOT was still descending towards Ryugu and wh ere it could be identified in the ONC photos. The blue line below the yellow line is the projection of these positions onto the asteroid surface - so this shows MASCOT's flight route was rather straight, and the lander touched down on a large edgy block at around 02:23 and 24 seconds UTC. From there, the asteroid lander hopped along the curved horizontal line towards the east-northeast and was then repeatedly imaged by the ONC. At around 02:14 and 04 minutes UTC MASCOT came to rest at its first location on the asteroid. Meanwhile, Hayabusa2 ascended to a higher observation position over Ryugu, making it more difficult to identify MASCOT in the images due to the lower image resolution. On the second asteroid day, MASCOT's mobility mechanism was activated. Another image will show the lander on 4 October at 00:55 and nine seconds UTC.

The image on the right shows the first image acquired by the DLR-developed MASCAM camera system during Hayabusa2's descent, shortly after separation from the landing module at a height of 51 metres with a viewing direction towards the south pole. The area captured by MASCAM is marked as an open triangle in the overview image on the left, which was taken with the wide-angle camera of the ONC (Optical Navigation Camera) system of the Hayabusa2 spacecraft. Particularly striking is a huge block near the South Pole, which stands out clearly above the horizon line and which the scientists named 'South Polar Rock'. It may be several dozen, and even up to 100 metres tall.

The second image of the DLR-developed MASCAM camera is directed obliquely downward on the asteroid Ryugu and covers areas east of the descent route. The area covered by MASCAM is marked as an open trapezoid in the overview image of the wide-angle camera of the ONC (Optical Navigation Camera) system of Hayabusa2. Compared with the first image, it is clear that MASCOT moved turbulently towards Ryugu, as expected, thus performing turns and rollovers. Both images show a huge boulder, which occupies the eastern (right) edge of the image in the MASCAM image and is several tens of metres in length. On the bottom left is MASCOT's shadow, which the Sun behind the landing probe is projecting onto the asteroid surface: MASCOT is 30 centimetres long. Ryugu is a body with no atmosphere, so the outlines of MASCOT (right) and Hayabusa2 (left) are sharp in the shadows projected onto the asteroid surface.

Before the first contact with a large rock on Ryugu, DLR's MASCAM camera photographed the area of the descent route with a backward-looking view. The area covered by MASCAM is marked as an open trapezoid in the overview image of the wide-angle camera of Hayabusa2's ONC (Optical Navigation Camera) system.

After first contact with the surface: the landing site environment
(https://www.dlr.de/dlr/en/Portaldata/1/Resources/portal_bilder/2018/2018_4/MASCOT_PM_Bild105_l.jpg)
The fifth image acquired by the DLR-developed MASCAM camera system (right) was taken shortly after the first contact with the ground, just a few metres above the surface of Ryugu. The line of sight is directed to the northwest and is located between the two white boundary lines in the overview image (left) acquired by the wide-angle camera of the ONC (Optical Navigation Camera) system on board Hayabusa2. Just as in the images from higher altitudes, no fine material, known as regolith, can be seen, even in the immediate vicinity of the surface. Regolith is formed on atmosphere-less bodies due to their permanent exposure to high-energy particles from space or micrometeorites due to the weathering of coarser material into dust. Instead, the area is extremely rugged and full of sharp blocks. The landing site environment is reminiscent of the Abydos landing site of the Philae lander, which was released on Comet 67P / Churyumov-Gerasimenko by the Rosetta spacecraft on 12 November 2014.

МОСКВА, 12 окт - РИА Новости. Первые данные и снимки с ровера MASCOT, севшего на поверхность астероида Рюгю на прошлой неделе, указывают не необычно малое количество пыли на этом небесном теле, причина чего пока остается загадкой для ученых, сообщает DLR.

"Поверхность астероида оказалась еще более безумной, чем мы предполагали. Самым удивительным стало то, что мы не нашли крупных скоплений реголита, что, по идее, невозможно - космическая эрозия должна была породить большие количества пыли", -- рассказывает Ральф Яуманн (Ralf Jaumann), научный руководитель миссии из Германского авиационно-космического центра (DLR).

Автоматическая станция "Хаябуса-2" была запущена в космос в начале декабря 2014 года для изучения, забора и возврата проб с астероида Рюгю. Как надеются ученые, она вернет на землю первые 100% "чистые" образцы первичной материи Солнечной системы.

Японский аппарат достиг цели в начале июня и начал длительную процедуру торможения и сближения с астероидом. Получив первые снимки и данные по устройству поверхности и недр Рюгю, зонд начал готовиться к процедуре по забору грунта.

Помимо этого, "Хаябуса-2" доставила к астероиду три спускаемых аппарата - два японских ровера MINERVA-II1, аналоги которых были отправлены к астероиду Итокава вместе с "Хаябусой-1", а также европейский аппарат MASCOT. Роботы Rover-1A и Rover-1B были успешно сброшены на поверхность Рюгю в конце сентября.

Сложная процедура по высадке их европейского "кузена" началась в прошлый понедельник, а успешная посадка состоялась утром в среду. Как отметили в DLR, спуск MASCOT был идеальным с точки зрения пилотов миссии и ее научной "половины", что позволило роботу почти сразу начать исследования и установить связь с "Хаябусой-2".

Робот успешно решил все научные задачи миссии, собрав все необходимые данные и снимки для раскрытия тайн геологии Рюгю и изучения образцов первичной материи Солнечной системы. Потратив на это примерно одни астероидные "сутки", MASCOT проработал на поверхности астероида еще два дня, совершив несколько прыжков по его поверхности и собрав несколько дополнительных наборов данных.

Недавно "Хаябуса-2" закончила передачу данных, собранных ровером, и Яуманн и его команда начали изучение тайн астероида и историю странствий MASCOT по его поверхности. Уже сейчас, как отметили планетологи, можно говорить о том, они натолкнулись на массу новых и при этом крайне интересных загадок.

К примеру, во всех восьми точках, которых коснулся MASCOT во время своих прыжков по поверхности Рюгю, ученые нашли большое число гигантских кубообразных и просто угловатых блоков и булыжников, чьи размеры в некоторых случаях достигали около ста метров. Как они возникли и из чего они состоят - пока не понятно.

Вдобавок, ученые обнаружили, что плотность материи Рюгю была неожиданно низкой, заметно меньше, чем у аналогичных по составу метеоритов, так называемых углистых хондритов, которые периодически находят в Антарктике и в Австралии. Эти различия, как отмечает Яуманн, могут быть связаны как с разным происхождением Рюгю и этих "небесных камней", так и с тем, как материя астероидов меняется при падении на Землю.

Анализ всего массива данных, собранных MASCOT в разных точках на поверхности астероида, как надеются ученые, поможет раскрыть эти тайны и получить более полное представление о том, как была устроена первичная материя Солнечной системы.

Выдвигаю гипотезу, которая объясняет форму, близкую к шару, глыбы и тсутствие пыли. 

Изначально будучи неправильной, как Итокава, формы и вращаясь астероид испытавал неравномерный прогрев внешних слоев. Это приводило к напряжениям в них, которое снималось расколами. Образовавшиеся при этом глыбы могли взлетать и падать, со временем сглаживая форму до более шарообразной. Пыль при этом тоже стряхивалась, но обратно не падала, ибо была уносима давлением солнечного света при ничтожной гравитации Рюгу.

Заявляю приоритет и аффторския права:)

ЦитатаTD1-R1-A operation schedule

The second touchdown rehearsal will be performed from October 14 - 16. The purpose of this rehearsal is to confirm the operation characteristics of the LRF (Laser Range Finder) which performs the altitude measurement at short distances. To test this, the spacecraft will descend to an altitude of about 25m. This will be the lowest altitude reached to date.

The first touchdown rehearsal (TD1-R1) was conducted between September 10 - 12. During this operation, problems occurred with the distance measurement taken with the LIDAR (laser altimeter) once the spacecraft had descended to about 600m. This caused the spacecraft to rise autonomously. The issue was addressed by adjusting the settings on the laser altimeter and it was confirmed that there were no further issues during the subsequent separation operations of MINERVA-II1 and MASCOT. As the spacecraft was only able to descend to an altitude of 600m during TD-R1, the LRF characteristics could not be verified. Therefore, we are performing this check with this rehearsal.

Although this is the second time a rehearsal operation has been performed, the name is TD1-R1-A as it is re-starting the challenge of TD1-R1.

  • Time: Approximate schedule time (in 10 minute increments). There is a possibility that this may change during operation. The time is the onboard time, so confirmation of the event is the radiowave propagation time of about 18 minutes later.
  • Spacecraft speed: This is the speed relative to the asteroid (minus is towards the asteroid, positive is away). Numerical value is displayed only when speed control is performed. After a speed control operation, the speed changes due to the gravitational force of Ryugu and other celestial bodies.
  • HP altitude: Distance to the center of Ryugu.
  • Near point altitude: Distance to the surface of Ryugu.

ЦитатаSchedule change for the touchdown operation

On the basis of the recent observations and operations in the vicinity of asteroid Ryugu by the Hayabusa2 spacecraft, the project team have decided to postpone the touchdown (TD) fr om the end of October this year (2018 ) to after January next year.

The upcoming main mission operations in 2018 will be: 
・October, 14 - 15: TD1-R1-A(equivalent to the second TD rehearsal)
・October, 24 - 25: TD1-R3(equivalent to the third TD rehearsal)
・Late November to December: operation for solar conjunction

The exact timing of the first touchdown will be considered during the operation period of solar conjunction, based on the results found during the rehearsal operations up to TD1-R3.

This decision to postpone touchdown is based on two main reasons. The first involves the improved understanding of the surface conditions on Ryugu by the operations conducted so far, and the second is the increased knowledge of the precision of the navigation guidance of the spacecraft.

As we discovered upon arrival at the asteroid, the surface of Ryugu is covered with numerous boulders with no wide, flat areas. The landing candidate sites of L08, L07 and M04 were therefore sel ected as locations offering a relatively safe region for touchdown on this difficult surface. Further examination of these candidate sites revealed that based on the data so far, a section of L08 seemed to be the best spot. The project team named this area L08-B (Figure 1).

Figure 1: Touchdown candidate sites L08, L07 and M04 (left). The red circle is the region named L08-B. This image was captured by the ONC-T (Optical Navigation Camera - Telescopic) from an altitude of about 3km on September 12, 2018 during the Touchdown 1 Rehearsal 1 (TD1-R1) operation.

In the area wh ere the spacecraft will touchdown, it is dangerous to have boulders with a height greater than about 50cm. Since the length of the sampler horn is about 1m and the spacecraft will be to be slightly inclined during the touchdown, there is a possibility that if a boulder with a height above about 50cm is present, it will strike the main body of the spacecraft or the solar panels. Viewed from the position in Figure 2, there is no boulder larger than 50cm in the area L08-B. L08-B is the widest part within all the candidate sites without a boulder larger than 50cm.

(http://www.hayabusa2.jaxa.jp/en/topics/20181014e_TD/img/fig2a.jpg) (http://www.hayabusa2.jaxa.jp/en/topics/20181014e_TD/img/Fig2be.jpg)
[Enlargement (a)] (http://www.hayabusa2.jaxa.jp/en/topics/20181014e_TD/img/fig2a.jpg) [(b)] (http://www.hayabusa2.jaxa.jp/en/topics/20181014e_TD/img/Fig2be.jpg)
Figure 2: L08-B (area enclosed within the red circle) and its peripheral area imaged from a lower altitude. The photograph was captured with the ONC-T (Optical Navigation Camera - Telescopic) from an altitude of about 1.9km during the MASCOT separation operation on October 3, 2018 at 05:41 JST. 
(Image credit ※: JAXA, University of Tokyo, Kochi University, Rikkyo University, Nagoya University, Chiba Institute of Technology, Meiji University, University of Aizu, AIST).


The difficulty is that area L08-B is only about 20m in diameter. Originally, it was assumed that a safe region for touchdown would be a flat area with a radius of about 50m (100m in diameter). This has now become a radius of just 10m; a fairly severe constraint. On the other hand, during the descent to an altitude of about 50m during the MINERVA-II1 and MASCOT separation operations, we were able to confirm that the spacecraft can be guided within a position accuracy of about 10m for a height 50m above the surface of Ryugu (Figure 3). This is a promising feature for touchdown.

Figure 3: Trajectory during the descent operations. TD1-R1 descended over the equator, the MINERVA-II1 operation approached the mid-latitudes in the northern hemisphere and the MASCOT operation was down towards the mid-latitudes in the southern hemisphere. It was confirmed that over the whole range of Hayabusa2 between latitudes ±30°, a location precision of about 10m at an altitude of 50m is possible. (Image credit: JAXA)

Although the spacecraft can be controlled with a position error of 10m at an altitude down to 50m, there remains the question of whether this accuracy can be retained as the spacecraft descends to the surface. This must be confirmed before touchdown operations. Therefore, the touchdown itself will be postponed until next year, during which time we will have two touchdown rehearsals; TD1-R1-A and TD1-R3.

The rehearsals are designed to check the accuracy of navigation guidance at altitudes less than 50m. For this check, the characteristics of the LRF (Laser Range Finger: used to measure the altitude in near distance) need to be tested. Originally, this was planned for the first touchdown rehearsal (TD1-R1: September 10 - 12, 2018 ). However, during this operation the LIDAR (laser altimeter) had an issue that the mode did not changed from the far mode to the near mode and the operation of the LRF could not be confirmed. The LIDAR was confirmed to have no issue in subsequent operations, leaving only the LRF to be tested. This will be performed with TD1-R1-A.

In TD1-R3, the item check list will depend on the results of TD1-R1-A. If TD1-R1-A has successfully confirmed the characteristics of the LRF, then the measurement results from the LRF will be used during control of the TD1-R3 operation and if possible, a target marker (TM) will be separated and the spacecraft confirmed to be able to properly track the target marker.
The results of these operations will be investigated in detail to plan the first touchdown. Furthermore, data fr om the surface of Ryugu taken by the MINERVA-II1 rovers and MASCOT lander will also provide important information for the touchdown. Although the first touchdown schedule is changed, we have enough time margins in our schedule, and our aim is a more reliable and safe operation through a comprehensive study of all the sources of information obtained so far during the Hayabusa2 project.

[TD1-R1-A] Information on the touchdown rehearsals and plans can also be found on our website. The red line here shows the approaching trajectory for the rehearsal. It is closer to the equator than for MINERVA-II1 and MASCOT separations. http://www.hayabusa2.jaxa.jp/en/topics/20181014e_TD/ ... (https://t.co/auUGXmOlnm)

★ Hayabusa2 status (the week of 2018.10.01) ★

Preparation for the MASCOT separation operation began on September 30 and descent began around noon JST on October 2. On October 3 at 10:57:20 JST, MASCOT was deployed at an altitude of 51m. MASCOT then landed on the surface of Ryugu and proceeded to operate for about 17 hours. The spacecraft then returned to the home position after staying for about 1 day at an altitude of around 3km. Originally, we planned to reach the home position on October 5, but due to the forecast of a typhoon approaching Japan at the weekend, this was delayed until October 8.
