ISS Leak Isolation Ops:

Спойлер

The crew ingressed the USOS segment today after spending an extended weekend in the Russian Segment to allow ground teams to monitor module pressures. The crew closed several module hatches on GMT 234 as part of a leak isolation test. The Environmental Control and Life Support (ECLS) community has been tracking an increase in nominal atmosphere leakage since October 2019. The motivation for finding the leak is to reduce the amount of consumables required to maintain the ISS pressure. Following USOS ingress, the crew reactivated the Waste & Hygiene Compartment (WHC) for operations and restowed items that were transferred to the Russian segment during the USOS isolation period.

Эксперимент на МКС подтвердил, что бактерии могут годами жить в открытом космосе
Это может подтвердить гипотезу, согласно которой жизнь не зародилась на Земле сама, а попала туда из космоса

ТОКИО, 26 августа. /ТАСС/. Японские ученые подтвердили, что в определенных условиях бактерии дейнококки (Deinococcus radiodurans) могут выдерживать жизнь в открытом космосе от двух до восьми лет. Исследование опубликовал научный журнал Frontiers in Microbiology, кратко об этом пишет NHK.

Ученых давно интересует, могут ли живые организмы переносить длительные космические путешествия. Ответ "да" на этот вопрос мог бы стать одним из подтверждений гипотезы панспермии, согласно которой жизнь могла попасть на Землю извне – например, внутри астероида, который некогда упал на поверхность нашей планеты.

Главное препятствие для выживания организмов в открытом космосе – это радиация. Землю от нее защищает атмосфера, космонавтов на МКС – стены станции и скафандры. Но у бактерий такой защиты нет. 

Чтобы проверить, могут ли бактерии несмотря на это выживать под воздействием космической радиации, японские ученые в течение трех лет экспериментировали с бактериями вида Deinococcus radiodurans на МКС. Эти бактерии известны тем, что могут очень долго время выдерживать ионизирующее излучение.

В начале эксперимента ученые сформировали колонии Deinococcus radiodurans разной толщины и высушили их. Затем космонавты прикрепляли их без какой-либо защиты с внешней стороны экспериментального модуля МКС "Кибо" на сроки от одного до трех лет. Все это время на них действовала космическая радиация, а также температура от –42 до 29 °С.

Тем не менее, после возвращения на Землю часть бактерий выжила и даже смогла размножаться. Микробы на поверхности колоний умирали, защищая таким образом тех, что находились ближе к их середине.

Авторы исследования подсчитали, что под воздействием ультрафиолетового излучения дейнококки могут прожить от 15 до 45 лет, а в темноте – до 48 лет. Таким образом, они могут перенести путешествие между планетами, что подтверждает панспермию.

NASA Makes Fifth State of Matter Aboard Space Station

 NASA Jet Propulsion Laboratory

26 авг. 2020 г.

Solid, liquid, gas, plasma... did you know there's also a fifth state of matter? Since 2018, NASA's Cold Atom Lab has been using the microgravity environment on the International Space Station to help chill atoms to almost absolute zero – the coldest temperature matter can reach. At these low temperatures, Cold Atom Lab produces the fifth state of matter, called a Bose-Einstein condensate.


Experiments with this fifth state of matter could lend deeper insight into how our world works on a fundamental level. For example, scientists will be able to measure the very faint tug of gravity that is still present aboard the station, and put Albert Einstein's theory about this fundamental force to the test. Studies of Bose-Einstein condensates aboard the station could also lead to new technologies, like better tools for navigation and more precise clocks.

The night lights of the southeastern U.S. are pictured as the International Space Station orbited over the Gulf of Mexico.

Mission controllers at NASA's Johnson Space Center are returning to normal operations today after setting backup control centers at remote locations. The International Space Station support team returned to Houston after setting up remote operations earlier this week when Hurricane Laura neared the Texas-Louisiana border.

The three Expedition 63 crew members continued their standard science and maintenance tasks this week after orbiting above Laura and sending down video (youtu.be/XWOyh_U5qRQ) and imagery of the storm. This comes after a four-night stay in the station's Russian segment during a test to locate the source of a minor cabin air pressure leak.

Today, Commander Chris Cassidy worked on swapping components on a U.S. oxygen generator. He replaced a hydrogen sensor then cleaned the critical life support device. Afterward, the NASA astronaut checked samples in the Materials Science Laboratory which processes experiments to discover new uses for a variety of materials such as metals, alloys, polymers, and more.

Veteran cosmonaut Anatoly Ivanishin worked Friday morning servicing communications gear inside the Soyuz MS-16 crew ship. During the afternoon, the three-time station resident handed Russian radiation detection gear to Cassidy for deployment in the orbiting lab's U.S. segment.

First-time space flyer Ivan Vagner of Roscosmos spent his day focusing on a variety of space technology studies using advanced photography gear. He explored ways to improve orbital navigation and improve the detection of landmarks on Earth.

The crew removed the processed calibration cartridge and inserted the first ESA batch-2b Sample Cartridge Assembly (SCA). Batch-2b serves two projects investigating how different phases organize in a structure when metallic alloys are solidified. The project Metastable Solidification of Composites (METCOMP) studies the phase formed by the reaction of the remaining liquid phase with an already formed solid, to form a second solid phase on cooling. For this purpose, Bronze (Copper-Tin Alloys) of different compositions will be processed. The other project, Solidification along a Eutectic path in Ternary Alloys (SETA), looks at how two phases that form together organize into lamellar, or fiber, structures when cooling Aluminum (Copper-Silver Alloys). Both projects will provide benchmark samples that will enable to test numerical models that aim to predict these structures.

Sunrise casts long shadows over a cloudy Philippine Sea as the International Space Station orbited off the coast of the Philippines.

The Expedition 63 crew kicked off the work week exploring space agriculture and spacecraft technologies. The trio also split the day on upcoming mission preparations and International Space Station maintenance.

Ongoing botany studies on the station have been teaching scientists, engineers and astronauts how to grow crops in space, so crews can feed themselves farther away from Earth. Future astronauts on long-term missions to the Moon, Mars and beyond will need to be self-sufficient with less support from mission controllers and resupply missions.

Commander Chris Cassidy set up the Advanced Plant Habitat during the afternoon for upcoming grow operations in the research facility. The controlled plant growth chamber automates the delivery of nutrients and light to support a variety edible plants for harvesting, analysis and tasting.

Cassidy is also gearing up for a U.S. resupply mission due to replenish the orbiting lab in early October. The NASA astronaut is sharpening his robotics skills on a computer to get ready to capture Northrop Grumman's Cygnus cargo craft with the Canadarm2 robotic arm.

A Russian technology experiment is using acoustics to locate micrometeoroid impacts on the space station. The two flight engineers, Anatoly Ivanishin and Ivan Vagner, partnered during the morning checking hardware and downloading data that may pinpoint the location of high-speed particle hits on the outside of the space lab.

The cosmonaut duo then spent the rest of Monday servicing life support gear and updating computer systems.

Posted Sep 1, 2020 at 4:33 pm


A waxing gibbous moon is pictured above the Earth's horizon as the station orbited above the Atlantic Ocean off the coast of Brazil.

It was a busy Tuesday aboard the International Space Station as the Expedition 63 crew reorganized science racks and serviced life support hardware.

Since its inception, the main focus of the orbiting lab has been research that is only possible in microgravity. Scientists take advantage of these unique insights to improve health and industry for humans on Earth and in space. A variety of specialized racks throughout the station's laboratory modules host numerous science experiments revealing phenomena only seen in weightlessness.

Commander Chris Cassidy and Flight Engineer Ivan Vagner partnered up today, moving three dedicated science racks, also known as EXPRESS racks, and installing them inside the U.S. Destiny, Japan's Kibo and Europe's Columbus lab modules.

A total of 11 refrigerator-sized EXPRESS racks are installed on the station supporting a multitude of experiments. The internationally sponsored studies are tended to by astronauts, remotely controlled by scientists on Earth, as well as programmed to run automatically.

Veteran cosmonaut Anatoly Ivanishin concentrated on life support maintenance tasks in the Russian segment of the space station. He replaced dust filters in the ventilation system in his side of the orbital lab before servicing an oxygen generator and a carbon dioxide filter.

Российский сегмент МКС пока не готов к автономной работе - Роскосмос
02.09.2020 12:00:17

Москва. 2 сентября. ИНТЕРФАКС - Для перехода на полностью автономную работу российскому сегменту МКС понадобится еще несколько модулей, заявил исполнительный директор "Роскосмоса" по пилотируемым программам Сергей Крикалев.

"Да, наверное, смогут, но присоединение других модулей с определенным функционалом все-таки потребуется. Все будет зависеть от конкретных условий", - сказал Крикалев в интервью официальному изданию "Роскосмоса" "Русский Космос", отвечая на вопрос, сможет ли российский сегмент МКС использоваться автономно.

По его словам, в "Роскосмосе" могут рассмотреть вопрос об отделении российского сегмента от американского, "если по каким-либо причинам будет принято решение о прекращении работы станции, а у нас останутся модули, продолжение эксплуатации которых будет целесообразно".

"Сейчас становится понятным: вложив так много труда в создание российского сегмента МКС, получив опыт эксплуатации этой станции, просто взять и прекратить работу - мягко говоря, нецелесообразно. Поэтому мое личное мнение: в ближайшие 10 лет МКС продолжит свое существование в том или ином виде", - добавил Крикалев.

Спойлер

В середине мая глава "Роскосмоса" Дмитрий Рогозин сообщил, что Ракетно-космическая корпорация "Энергия" под руководством Игоря Озара, занявшего должность исполняющего обязанности гендиректора, займется разработкой концепции новой орбитальной станции.

Позднее Рогозин сообщил о планах создания собственной космической станции после 2030 года. По его словам, на станции будут осуществляться дозаправка спутников и сборка аппаратов для освоения дальнего космоса.

В станции планируется использовать часть новых российских модулей, разрабатываемых для МКС, в том числе узловой и энергетический.

В декабре 2019 Рогозин сообщил, что Россия может отказаться от запуска узлового и научно-энергетического модуля ради создания лунной станции. "Мы должны взвесить, есть ли смысл отправлять последующие модули на МКС, если жизнь МКС уже понятна, это 2028 год, а у этих модулей будет ресурс 15-20 лет. Стоит ли их отправлять на три-четыре года, чтобы потом топить в океане вместе со станцией? Я не уверен", - отметил глава "Роскосмоса".

Скончавшийся в мае от коронавируса генконструктор "Энергии" Евгений Микрин ранее называл целесообразным после завершения проекта МКС создание российской орбитальной станции, не исключив при этом международное участие в проекте.

"На эту станцию можно будет перенести все дорогостоящее оборудование с российского сегмента МКС. Она будет состоять из пяти модулей. Первые три - МЛМ, узловой и НЭМ с МКС - плюс ещё два новых. Она будет иметь массу 60 тонн", - заявлял Микрин.

[свернуть]

В данный момент Россия планирует запустить к МКС три новых модуля - "Наука" узловой и научно-энергетический. Как сообщал в интервью "Интерфаксу" гендиректор компании "Главкосмос" Дмитрий Лоскутов, дооснащение российского сегмента МКС данными модулями позволит в течение трех лет сделать его независимым.

The well-lit Middle Eastern cities along the Persian Gulf coast of the Arabian Peninsula to the north of Iran were photographed from the International Space Station during an orbital night pass.

The Expedition 63 crew serviced a variety of International Space Station hardware today ensuring research, power and life support systems continue operating in good condition. Heart research and team psychology studies also filled today's science schedule.

Commander Chris Cassidy of NASA wrapped up science rack swap work that he began on Monday. He finished moving and reinstalling three advanced science facilities, known as EXPRESS racks, in three different lab modules. The rack exchanges will support future experiments being delivered on an upcoming Cygnus resupply mission from Northrop Grumman.

Afterward, Cassidy collected water samples from the potable water dispenser for analysis on Earth and on the station. The veteran astronaut also inspected U.S. module hatches and replaced pipes in the orbiting lab's restroom, known as the Waster and Hygiene Compartment.

Three-time space station cosmonaut Anatoly Ivanishin strapped himself on an exercise bike this morning for an assessment of his cardiac activity in space. First-time space flyer Ivan Vagner assisted Ivanishin attaching sensors to the test subject and monitoring his activities during the hour-long test.

The Russian duo then checked battery temperatures and connections before studying how international space crews interact with mission controllers around the world. Ivanishin went on to set up advanced Earth observation gear while Vagner worked on power system diagnostics.
