NASA has sel ected a new space mission that will help astronomers understand both how our universe evolved and how common are the ingredients for life in our galaxy's planetary systems.
The Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) mission is a planned two-year mission funded at $242 million (not including launch costs) and targeted to launch in 2023.
"I'm really excited about this new mission," said NASA Administrator Jim Bridenstine. "Not only does it expand the United States' powerful fleet of space-based missions dedicated to uncovering the mysteries of the universe, it is a critical part of a balanced science program that includes missions of various sizes."
SPHEREx will survey the sky in optical as well as near-infrared light which, though not visible to the human eye, serves as a powerful tool for answering cosmic questions. Astronomers will use the mission to gather data on more than 300 million galaxies, as well as more than 100 million stars in our own Milky Way.

"This amazing mission will be a treasure trove of unique data for astronomers," said Thomas Zurbuchen, associate administrator for NASA's Science Mission Directorate. "It will deliver an unprecedented galactic map containing 'fingerprints' fr om the first moments in the universe's history. And we'll have new clues to one of the greatest mysteries in science: What made the universe expand so quickly less than a nanosecond after the big bang?"
SPHEREx will survey hundreds of millions of galaxies near and far, some so distant their light has taken 10 billion years to reach Earth. In the Milky Way, the mission will search for water and organic molecules – essentials for life, as we know it – in stellar nurseries, regions where stars are born from gas and dust, as well as disks around stars wh ere new planets could be forming.
Every six months, SPHEREx will survey the entire sky using technologies adapted fr om Earth satellites and Mars spacecraft. The mission will create a map of the entire sky in 96 different color bands, far exceeding the color resolution of previous all-sky maps. It also will identify targets for more detailed study by future missions, such as NASA's http://James Webb Space Telescope (http://james%20webb%20space%20telescope/) and http://Wide Field Infrared Survey Telescope (http://wide%20field%20infrared%20survey%20telescope/).
NASA's Astrophysics Explorers Program requested proposals for new missions in September 2016. Nine proposals were submitted, and two mission concepts were selected for further study in August 2017. After a detailed review by a panel of NASA and external scientists and engineers, NASA determined that the SPHEREx concept study offered the best science potential and most feasible development plan.
The mission's principal investigator is James Bock of the California Institute of Technology (Caltech) in Pasadena, California. Caltech will work with NASA's Jet Propulsion Laboratory (JPL) to develop the mission payload. JPL will also manage the mission.
Ball Aerospace in Broomfield, Colorado, will provide the SPHEREx spacecraft and mission integration. The Korea Astronomy & Space Science Institute in Daejeon, Republic of Korea, will contribute test equipment and science analysis.
NASA's Explorer program, managed by the agency's Goddard Space Flight Center in Greenbelt, Maryland, is the agency's oldest continuous program, designed to provide frequent, low-cost access to space using principal investigator-led space science investigations relevant to the Astrophysics and Heliophysics programs in NASA's Science Mission Directorate.
The program has launched more than 90 missions, beginning in 1958 with Explorer 1, which discovered the Earth's radiation belts. Another Explorer mission, the Cosmic Background Explorer, which launched in 1989, led to a Nobel Prize.

ЦитироватьНАСА запустит зонд для изучения "темных веков" Вселенной в 2023 году
МОСКВА, 14 фев – РИА Новости. Ученые и инженеры НАСА приступили к созданию зонда SPHEREx, главной задачей которого станет изучение так называемых "темных веков" Вселенной – первой эпохи ее жизни после Большого Взрыва. Запуск аппарата намечен на 2023 год, сообщает сайт (https://www.nasa.gov/press-release/nasa-selects-new-mission-to-explore-origins-of-universe) космического агентства.
"Эта миссия станет настоящим рогом изобилия для астрофизиков. Она составит первую карту следов первых мгновений жизни Вселенной и приблизит нас к ответу на одну из главных тайн современной науки – что заставляло мироздание расширяться с невозможно высокой скоростью в первую наносекунду после Большого Взрыва", — заявил Томас Цурбухен, заместитель руководителя научного подразделения НАСА.

Спойлер

После Большого Взрыва и первичного расширения Вселенной, когда в ней царили высокие энергии и свет, ее материя быстро охладилась, и в ней наступила полная темнота. Когда зажглись первые звезды, эта тьма рассеялась далеко не сразу.
Ученые называют эти "темные века" эпохой реионизации по той причине, что в это время Вселенная постепенно становилась "прозрачной" и доступной для наблюдений в результате ионизации облаков водорода в первых галактиках и в пустотах между ними.
Наблюдения телескопов "Планк" и WMAP подтверждают существование этого периода, однако его длительность и сам механизм "просветления" Вселенной пока остаются предметом споров среди космологов.
К примеру, часть ученых полагает, что главным двигателем этого процесса могли быть первые сверхмассивные черные дыры, вырабатывавшие гигантские количества ультрафиолета и рентгена. Другие специалисты с ними не согласны, и приписывают эту роль первым звездам, имевшим необычно высокую яркость, большие размеры и очень короткие сроки жизни.
Решить эту загадку сможет зонд SPHEREx, о планах по созданию которого сегодня ночью заявил Джим Брайденстайн, текущий глава НАСА. На его постройку агентство планирует выделить относительно небольшую сумму средств, около 242 миллионов долларов.
Эта миссия была выбрана в качестве победителя очередного конкурса на создание малых исследовательских астрофизических космических аппаратов Astrophysics Explorers, в рамках которого уже были созданы телескопы NuSTAR, NICER, TESS и прочие аппараты "среднего" ценового диапазона.
По текущим планам НАСА, SPHEREx будет наблюдать за свыше 300 миллионами галактик и 100 миллионами звезд в Млечном Пути, решая две разных задачи. В первом случае он будет искать следы "темных веков" Вселенной, а во втором – оценивать количество воды в новорожденных звездных системах.
Наиболее интересные галактики, "зародыши" планет и светил, открытые SPHEREx , станут приоритетными целями для более детального изучения для двух "больших" миссий НАСА, телескопов "Джеймс Уэбб" и WFIRST.
Как надеются ученые, эти замеры помогут нам понять, что именно сделало Вселенную прозрачной и как часто вода присутствует на потенциальных "двойниках" Земли, где может существовать внеземная жизнь.

• Изучить физику расширения Вселенной;
• Исследовать историю света, изучаемого другими галактиками;
• Узнать, насколько распространены в Млечном пути главные ингредиенты жизни: вода, моноксид углерода, диоксид углерода и метанол.
  

ЦитироватьПроект космического телескопа SphereX НАСА переходит на новый этап реализации
Новый космический телескоп НАСА, называемый Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, или SPHEREx, стал на один шаг ближе к запуску. Согласно терминологии НАСА, на днях официально начался этап С проекта миссии. Это означает, что агентство одобрило предварительный план конструкции обсерватории, и теперь начались работы по созданию окончательной, подробной конструкции, а также строительству требуемого оборудования и написанию к нему программного обеспечения.
Телескоп SPHEREx, подготовку которого к запуску производит Лаборатория реактивного движения НАСА, планируется отправить в космос не ранее июня 2024 г. и не позднее апреля 2025 г. Его инструменты будут способны обнаруживать излучение в ближнем инфракрасном диапазоне. На протяжении основной миссии продолжительностью два года при помощи этого телескопа будет четырежды составлена карта всего неба и сформирован огромный массив данных по звездам, галактикам, туманностям и многим другим небесным объектам.
Перед научной командой обсерватории SPHEREx стоят три основных цели. Первая цель состоит в том, чтобы выяснить, что именно произошло в течение первых крохотных долей секунды после Большого взрыва. Считается, что в это время происходило резкое расширение самого пространства, которое ученые называют инфляцией. Такое резкое расширение пространства должно было повлиять на распределение в нем материи, и признаки этого влияния могли сохраниться до настоящего времени. При помощи инструмента SPHEREx ученые составят карты расположения миллиардов галактик Вселенной и будут искать на этих картах статистические закономерности распределения, указывающие на инфляцию.
Вторая научная цель миссии SPHEREx состоит в изучении истории формирования галактик, начиная с эпохи формирования первых галактик во Вселенной и вплоть до настоящего времени. Инструмент SphereX позволит осуществить эти исследования посредством наблюдения тусклого фонового света, излучаемого совместно всеми галактиками Вселенной.
Наконец еще одна цель, стоящая перед миссией SPHEREx, заключается в поисках водяного льда и замороженных органических молекул – «строительных кирпичиков» жизни на Земле – вокруг вновь формирующихся звезд в нашей Галактике.
Команда проекта SPHEREx планирует 29 месяцев на подготовку компонентов оборудования миссии, после чего начнется следующий этап реализации проекта, на котором компоненты будут собраны воедино, пройдут испытания, а затем будут окончательно подготовлены к запуску.

Автор: Yonhap (https://translate.googleusercontent.com/translate_c?depth=1&hl=ru&prev=search&pto=aue&rurl=translate.google.com&sl=en&sp=nmt4&u=http://www01.koreaherald.com/search/list_name.php%3Fbyline%3DYonhap&usg=ALkJrhh08-yHHbqEzY_zFcP4CE_VjT0CDQ)

Министерство науки Южной Кореи заявило в среду, что начало производство космического телескопа в рамках совместного проекта с Национальным управлением США по аэронавтике и исследованию космического пространства (НАСА) и Калифорнийским технологическим институтом (Калифорнийский технологический институт).

Министерство науки и информационных технологий заявило, что НАСА одобрило предварительный проект спектрофотометра для истории Вселенной, эпохи реионизации и исследователя льдов (SPHEREx), что подготовило почву для его строительства.

По сообщению министерства, космический телескоп был впервые спланирован и предложен НАСА в результате совместных исследований Корейского института астрономии и космических наук (KASI) и Калифорнийского технологического института.

KASI - единственный институт за пределами США, который принимает участие в проекте, в который также входят Лаборатория реактивного движения НАСА и Ball Aerospace.

По данным Министерства науки и ИКТ Южной Кореи, SPHEREx, запуск которого запланирован на 2024 год, будет использовать спектроскопию для четырехкратного картирования всего неба в течение двух с половиной лет своей миссии по созданию базы данных звезд и галактик.

Космический телескоп построит карту спектроскопии всего неба в ближнем инфракрасном диапазоне и будет наблюдать 102 цвета в ближнем инфракрасном диапазоне.

«Это похоже на переход от черно-белых изображений к цветным; это похоже на переход из Канзаса в страну Оз», - сказал в пресс-релизе Аллен Фаррингтон, менеджер проекта SPHEREx в Лаборатории реактивного движения НАСА.

В министерстве заявили, что трехмерные данные, собранные телескопом, могут помочь раскрыть тайны космоса, такие как раннее формирование Вселенной.

Исследователь KASI сказал, что институт создаст фильтр для космического телескопа, а также оборудование для тестирования инструментов телескопа.

В последнее время Южная Корея активизировала свои усилия в космических проектах, и страна намерена запустить свою первую космическую ракету собственного производства в октябре этого года. (Йонхап)

NASA has selected Space Exploration Technologies (SpaceX) of Hawthorne, California, to provide launch services for the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx) mission. SPHEREx is a planned two-year astrophysics mission to survey the sky in the near-infrared light, which, though not visible to the human eye, serves as a powerful tool for answering cosmic questions involving the birth of the universe, and the subsequent development of galaxies.

It also will search for water and organic molecules – essentials for life as we know it – in regions where stars are born from gas and dust, known as stellar nurseries, as well as disks around stars where new planets could be forming. Astronomers will use the mission to gather data on more than 300 million galaxies, as well as more than 100 million stars in our own Milky Way galaxy.

The total cost for NASA to launch SPHEREx is approximately $98.8 million, which includes the launch service and other mission related costs.

The SPHEREx mission currently is targeted to launch as early as June 2024 on a Falcon 9 rocket from Space Launch Complex-4E at Vandenberg Air Force Base in California.

NASA's Launch Services Program at the agency's Kennedy Space Center in Florida will manage the SpaceX launch service. The mission, which is funded by the Astrophysics Division of NASA's Science Mission Directorate at the agency's headquarters in Washington, is led by the Explorer's Program at NASA's Goddard Space Flight Center in Greenbelt, Maryland. NASA's Jet Propulsion Laboratory in Southern California is responsible for the mission's overall project management, systems engineering, integration, and testing and mission operations.

ЦитироватьЗапуск миссии PUNCН запланирован на 2025 год
Более 60 ученых и инженеров провели 23-24 августа в Юго-Западном научно-исследовательском институте встречу, чтобы начать сотрудничество в рамках подготовки миссии NASA «Поляриметр для объединения короны и гелиосферы» (Polarimeter to Unify the Corona and Heliosphere, PUNCН). PUNCH полетит в космос вместе с миссией «Спектрофотометр для изучения истории Вселенной, эпохи реионизации и льдов» (SPHEREx) на борту РН Falcon-9, пишет AstroNews.

PUNCH, который состоит из четырех спутников размером с чемодан, будет изучать внешнюю атмосферу Солнца, корону и то, как генерируется солнечный ветер. Космический аппарат будет также отслеживать выбросы корональной массы, что поможет ученым лучше изучить их эволюцию и разработать новые методы прогнозирования таких извержений.

Команда PUNCH теперь сможет скорректировать свой график, чтобы сроки проведения работ соответствовали новой дате запуска не ранее апреля 2025 года. Такой расширенный график позволит также смягчить остроту проблем, возникающих в цепочке поставок после пандемии.

После запуска спутники PUNCH будут расставлены по линии светораздела Земли, чтобы создать непрерывный полный обзор солнечной короны и внутренней области солнечной системы. Три спутника PUNCH будут оборудованы инструментом Wide Field Imager, а в четвертом спутнике установят коронограф Narrow Field Imager, который будет изучать области, близкие к Солнцу. Все четыре камеры будут синхронизированы в полете так, чтобы команда исследователей смогла объединять несколько изображений в одно большое.

Earth is immersed in material streaming from the Sun. This stream, called the solar wind, is washing over our planet, causing breathtaking auroras, impacting satellites and astronauts in space, and even affecting ground-based infrastructure. 
NASA's PUNCH (https://nasa.gov/punch) (Polarimeter to Unify the Corona and Heliosphere) mission will be the first to image the Sun's corona, or outer atmosphere, and solar wind together to better understand the Sun, solar wind, and Earth as a single connected system.  
Launching no earlier than Feb. 28, 2025, aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California, PUNCH will provide scientists with new information about how potentially disruptive solar events form and evolve. This could lead to more accurate predictions about the arrival of space weather events at Earth and impact on humanity's robotic explorers in space.

The PUNCH mission's four suitcase-sized satellites have overlapping fields of view that combine to cover a larger swath of sky than any previous mission focused on the corona and solar wind. The satellites will spread out in low Earth orbit to construct a global view of the solar corona and its transition to the solar wind. They will also track solar storms (https://science.nasa.gov/sun/solar-storms-and-flares/) like coronal mass ejections. Their Sun-synchronous orbit will enable them to see the Sun 24/7, with their view only occasionally blocked by Earth.  
Following a 90-day commission period after launch, PUNCH is scheduled to conduct science for at least two years. The mission is launching as a rideshare with NASA's next astrophysics observatory, SPHEREx (https://www.jpl.nasa.gov/missions/spherex/) (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer).

Цитировать- На пресс-конференции SPHEREx и PUNCH перед запуском одной из причин задержки запуска была названа проблема интеграции с «сборкой несоответствия импеданса», которая имеет 120 вставок, которые стали «овальными». Это привело к замене креплений. Возможно, все остальные знают, что это значит, но я хотел бы получить простое объяснение на английском языке.
-  В стартовом стеке SPHEREx используется этот специальный адаптер полезной нагрузки, который минимизирует воздействие запуска ракеты на космический аппарат (например, количество ударов и вибраций). Для того чтобы прикрепить этот адаптер к кольцу ESPA (круглая конструкция, на которой установлены спутники PUNCH), в нем есть 120 вставок, через которые проходят болты, чтобы прикрепить его к кольцу ESPA. Они должны быть круглыми, но стали овальными. Это могло привести к тому, что у адаптера будет немного больше места для маневра. Похоже, что они использовали более крупные крепежи, чтобы заполнить пустое пространство в этих вставках, которые в противном случае были бы там, чтобы обеспечить плотное крепление.

SPHEREx — не первая миссия, в которой используется этот адаптер. Ранее он использовался в нескольких миссиях, включая Psyche, IXPE и Sentinel-6 Michael Freilich.

ЦитироватьSignal Acquired: NASA's SPHEREx Begins Science Mission
NASA's SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) mission controllers on Earth have received full acquisition of signal from the observatory, indicating the spacecraft is functioning nominally and is power positive.
In the weeks ahead, the SPHEREx team will prepare the observatory for its survey operations – conducting calibrations, cooling the telescope to its designed operating temperature, and characterizing its optical performance in space.

Спойлер

Over a two-year planned mission, SPHEREx will then collect data on more than 450 million galaxies along with more than 100 million stars in the Milky Way in order to explore the origins of the universe, contributing to NASA Science's key goals to discover the secrets of the universe and search for life elsewhere.
The mission's 3D all-sky map will help scientists answer big-picture questions about the universe. The mission will investigate a cosmic phenomenon called inflation that caused the universe to expand rapidly for a fraction of a second after the big bang, measure the collective glow created by galaxies near and far, including hidden galaxies that have not been individually observed, and search the Milky Way galaxy for hidden reservoirs of water, carbon dioxide, and other essential ingredients for life.
The SPHEREx mission's ability to scan large sections of the sky quickly and gather data on millions of objects complements the work of more targeted telescopes, like NASA's Hubble and James Webb, and the observatory's data will be freely available to scientists around the world, providing a new encyclopedia of information about hundreds of millions of cosmic objects.

Mission controllers for NASA's PUNCH (Polarimeter to Unify the Corona and Heliosphere) have received full acquisition of signal from the four small satellites, indicating that they are functioning normally and at full power.

Спойлер

Over a two-year planned mission, PUNCH will make global, 3D observations of the Sun's corona, or outer atmosphere, and how it becomes the solar wind.
The solar wind and energetic solar events like solar flares and coronal mass ejections can create space weather effects throughout the solar system. These phenomena can have a significant impact on human society and technology, from sparking and intensifying auroras to interfering with satellites or triggering power outages.
The measurements from PUNCH will provide scientists with new information about how these potentially disruptive events form and evolve. This could lead to more accurate and crucial predictions about the arrival of space weather events at Earth and their impact on humanity's robotic explorers in space.

All four spacecraft are synchronized to serve as a single "virtual instrument" that spans the whole PUNCH constellation. The PUNCH mission will downlink data multiple times a day via ground-based antennas on Earth that are managed by the Swedish Space Corporation. Then, the data will be sent to the mission operations center at Southwest Research Institute (SwRI) offices in Boulder, Colorado, which will share it with the science operations center, also at SwRI.
The data will be available to the public at the same time it is available to the science team. All PUNCH data will be published through the Solar Data Analysis Center at NASA's Goddard Space Flight Center in Greenbelt, Maryland, ensuring open access to the scientific community and public...

ЦитироватьNASA's newest astrophysics space telescope launched in March on a mission to create an all-sky map of the universe. Now settled into low-Earth orbit, SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) has begun delivering its sky survey data to a public archive on a weekly basis, allowing anyone to use the data to probe the secrets of the cosmos

ЦитироватьSPHEREx, a NASA explorer satellite launched on 11 March 2025, is carrying out the first all-sky near-infrared spectral survey. The satellite observes in 102 spectral bands from 0.75 to 5.0 um with a resolving power ranging from 35 to 130 in 6.2 arcsecond pixels. The observatory obtains a 5-sigma depth of 19.5 - 19.9 AB mag for 0.75 to 3.8 um and 17.8 - 18.8 AB mag for 3.8 to 5.0 um after mapping the full sky four times over two years. Scientifically, SPHEREx will produce a large galaxy redshift survey over the full sky, intended to constrain the amplitude of inflationary non-Gaussianity. The observations will produce two deep spectral maps near the ecliptic poles that will use intensity mapping to probe the evolution of galaxies over cosmic history. By mapping the depth of infrared absorption features over the Galactic plane, SPHEREx will comprehensively survey the abundance and composition of water and other biogenic ice species in the interstellar medium. The initial data are rapidly released in the form of spectral images to the public. The project will release specialized data products over the life of the mission as the surveys proceed. The science team will also produce specialized spectral catalogs on planet-bearing and low-mass stars, solar system objects, and galaxy clusters 3 years after launch. We describe the design of the instrument and spacecraft, which flow from the core science requirements. Finally, we present an initial evaluation of the in-flight performance and key characteristics.
