МОСКВА, 25 апр - РИА Новости. Пожарная сигнализация сработала накануне на американском сегменте Международной космической станции (МКС), однако тревога оказалась ложной, сообщило в четверг НАСА.

На сайте НАСА отмечается, что сигнализация сработала в среду в американском грузовом корабле Cygnus, прилетевшем на станцию 19 апреля. Причина ложного срабатывания не сообщается, однако отмечается, что в тот день астронавты занимались разгрузкой корабля Cygnus.

Между тем источник РИА Новости в ракетно-космической отрасли сообщил, что это уже не первое ложное срабатывание пожарной сигнализации в корабле Cygnus. "Вскоре после открытия люка в корабль 19 апреля также зазвучала сирена. Специалисты посчитали, что это связано со скоплением пыли в корабле", - пояснил собеседник агентства.

The aurora australis, also known as the "southern lights", is pictured as the International Space Station orbited 265 miles above the Indian Ocean southwest of Australia.

Vein scans and eye checks were on the schedule today as the Expedition 59 crew continues ongoing biomedical studies. The International Space Station is also getting ready to host a sixth spacecraft when it arrives next week.

Scientists have been observing the space residents all week as they seek to understand the effects of the upward flow of body fluids in space. Flight Engineer Anne McClain worked on the Fluid Shifts experiment again today attaching body electrodes to NASA astronaut Nick Hague and conducting ultrasound scans of his veins. She also peered into his eyes using optical tomography coherence hardware. Results may help flight surgeons prevent the increased head and eye pressure caused by the upward fluid shifts astronauts report in space.

NASA is also learning how to support longer human missions farther out into space. Feeding crews without expensive cargo missions and fuel-consuming inventories is critical. As a result, the station provides a variety of greenhouse facilities for plant cultivation and research. Christina Koch of NASA set up new botany hardware today to enable the ongoing research and harvesting of lettuce and mizuna in space.

The SpaceX Dragon resupply ship is due to liftoff Tuesday at 4:21 a.m. EDT on its 17th contracted cargo mission to the station. Canadian Space Agency astronaut David Saint-Jacques is training to capture Dragon with the Canadarm2 robotic arm when it arrives Thursday May 2 at 6:50 a.m. A pair of new experiments it is delivering will explore atmospheric carbon dioxide as well as X-ray frequency communication techniques.

NASA to Broadcast Next Space Station Resupply Launch, Prelaunch Activities

Editor's Note: Launch time has been upd ated to 4:21 a.m. EDT and spacecraft capture now is se t for 6:50 a.m. NASA TV coverage off capture will begin at 5 a.m. (Updated April 25, 2019)

NASA commercial cargo provider SpaceX is targeting no earlier than 4:21 a.m. EDT Tuesday, April 30, for the launch of its next resupply mission to the International Space Station. Live coverage will begin on NASA Television and the agency's website Monday, April 29, with prelaunch events.  

This is the 17th SpaceX mission under NASA's Commercial Resupply Services contract. The Dragon spacecraft will deliver supplies and critical materials to support dozens of the more than 250 science and research investigations that will occur during Expeditions 59 and 60. The spacecraft'sunpressurized trunk will transport NASA's Orbiting Carbon Observatory-3 (OCO-3) and Space Test Program-Houston 6 (STP-H6). 

OCO-3 will be installed robotically on the exterior of the space station's Japanese Experiment Module Exposed Facility Unit, where it will measure and map carbon dioxide fr om space to increase our understanding of the relationship between carbon and climate. STP-H6 is an X-ray communication investigation that will be used to perform a space-based demonstration of a new technology for generating beams of modulated X-rays. This technology may be useful for providing efficient communication to deep space probes, or communicating with hypersonic vehicles wh ere plasma sheaths prevent traditional radio communications.

The spacecraft will take two days to reach the space station before installation on Thursday, May 2. When it arrives, astronaut David Saint-Jacques of the Canadian Space Agency will grapple Dragon, with NASA astronaut Nick Hague serving as backup. NASA astronaut Christina Koch will assist by monitoring telemetry during Dragon's approach. After Dragon capture, mission control in Houston will send commands to the station's arm to rotate and install the spacecraft on the bottom of the station's Harmony module.

    ЦитироватьНа МКС произошел сбой в системе очистки воздуха
    Москва. 25 апреля. INTERFAX.RU - На Международной космической станции отключилась экспериментальная установка по удалению углекислого газа из ее атмосферы, сообщило в четверг НАСА.
    После обновления параметров программы системы Life Support Rack (LSR) Европейского космического агентства устройство продолжило функционировать в штатном режиме.
    При этом, как сообщает НАСА, перезапуск на некоторое время был прерван в связи со срабатыванием пожарной сигнализации в пристыкованном к МКС американском грузовом космическом корабле Cygnus. Однако она оказалась ложной.
    Проблема в работе экспериментального оборудования, доставленного на МКС японским грузовым кораблем в октябре прошлого года, возникла еще во вторник. После приостановки работы системы к очистке воздуха сразу были готовы подключиться схожие системы, размещенные в американских модулях станции LAB и Node 3.
    Экспериментальная система LSR позволяет удалять из атмосферы станции углекислый газ и возобновляет до 50% содержание кислорода. Планируется, что установка будет работать на МКС не менее одного года в целях проверки надежности технологии для будущих миссий, отмечает NASA.
    В настоящее время экипаж МКС состоит из российских космонавтов Олега Кононенко и Алексея Овчинина, американских астронавтов Энн Макклейн, Кристины Кох и Ника Хейга и канадского астронавта Давида Сен-Жака.

    Hermes to Bring Asteroid Research to the ISS

    Asteroid researchers on Earth will soon gain a powerful new way to remotely conduct experiments aboard the International Space Station. The device, called the Hermes Facility, is an experiment station that can communicate with scientists on the ground and give them the ability to control their studies almost as if they were in space themselves. Hermes will be carried to the space station aboard the SpaceX CRS-17 ferry flight.

    Hermes is the creation of Dr. Kristen John, a researcher with the Astromaterials Research and Exploration Science (ARES) division at NASA's Johnson Space Center (JSC). John and her research team developed Hermes as a way to study how samples of simulated asteroid particles behave in microgravity and the vacuum of space.


    Hermes Principal Investigator, Kristen John, stands in front of the Hermes hardware. On the right is the Hermes Facility, and on the the left is Cassette-1, the first set of science experiments to be installed in the Facility.

    Researching Regolith
    Спойлер
    The material John is studying with Hermes is called asteroid regolith. The term is used for the layer of dusty, fragmented debris covering asteroids and moons created by impacts from meteorites and other forces on their surfaces.

    "We need to study this material to understand how it's going to affect our spacecraft that interact with the surface of asteroids, or the joints of spacesuits worn by astronauts one day exploring them," John said.

    Studying regolith also helps scientists understand the underpinning of how asteroids, moons and planets, such as our Earth, developed.

    John and her team designed Hermes to connect to the station's existing systems – including communications – so that it could be completely monitored and controlled from the ground. Hermes is also made to be easily adapted to many types of experiments.

    "We named it for the Greek messenger god, Hermes, because we've designed a system that can deliver research data and experiments back forth between space and scientists," John said.


    The Cassette-1 hardware sits in a lab at Johnson Space Center. The Cassette includes the four experiments, electronics to control the experiments, and a vacuum system on the underside consisting of transducers, pipes, hoses, and valves.

    Hermes is roughly the size of a large desktop computer and the experiments themselves are housed inside a removable carrier, called a cassette, which slides into Hermes.

    John was assisted in designing and building Hermes by a team consisting of JSC, the University of Central Florida and researchers and students affiliated with Texas A&M University through a partnership with Texas Space, Technology, Applications and Research.

    The JSC team included Kenton Fisher, an ARES engineer who led the development of Hermes' vacuum system, and project manager Veronica Saucedo with the Project Management and Integration Office of the Engineering Directorate.

    "There is no greater satisfaction than seeing this project through from concept to delivery," Saucedo said. "I'm excited to see how the capability of this game-changing facility impacts asteroid, planetary science and exploration research."

    The Experiment
    Спойлер
    The space station crew will install Hermes into an EXPRESS rack aboard the lab.

    "After that, the crew will flip a few switches, and we'll basically take over from there," John said.

    John's experiments for Cassette-1 are housed inside four clear, 10-inch plastic tubes containing materials meant to simulate regolith. Three of the tubes hold different-sized particles of silica glass. The fourth tube has a meteorite simulant which is a blend of variously sized particles, formulated especially for the experiment by Professor Addie Dove and students from the University of Central Florida.

    "This experiment gave our students a chance to work on hardware that will actually fly on the ISS," Dove said. "They had to understand the experiment design and fabrication cycle, how to meet specifications and produce a quality product. This is much different than what they have to do in classes and provides valuable experience."

    Over the coming months, John and her team will be watching to see how the regolith particles behave in response to long duration exposure to microgravity, and to changes in pressure, temperature, shocks from impacts and other forces. Once the regolith experiments inside Cassette-1 are complete, it will be removed from Hermes, returned to Earth and replaced with a new cassette of different experiments.

    ЦитироватьРКК «Энергия»: разработана одновитковая схема сближения
    26.04.2019

    Специалисты РКК «Энергия» разработали одновитковую схему полета космических кораблей, которая предполагает сближение с Международной космической станцией примерно за 2 часа.

    Главное преимущество такой схемы – сокращение времени пребывания космонавтов в небольшом объеме корабля. Еще одним плюсом одновитковой схемы является быстрая доставка на станцию различных биоматериалов для проведения научных экспериментов на МКС. Кроме того, чем быстрее происходит сближение корабля со станцией, тем больше экономятся топливо и другие ресурсы, необходимые для обеспечения полета.

    Реализация одновитковой схемы потребует соблюдения ряда жестких баллистических условий по относительному положению корабля и станции. Однако разработанная специалистами «Энергии» специальная методика позволит использовать её даже чаще, чем ставшую уже привычной четырехвитковую стратегию сближения. Чем выше широта космодрома, с которого выполняется пуск, тем эффективнее использование этой методики. Так, например, с космодрома Восточный запуски по одновитковой схеме можно будет осуществлять без предварительных коррекций орбиты МКС, а в идеале – даже ежесуточно.

    – Мы уже применяем двухвитковую схему сближения, которую успешно опробовали на двух полетах грузовых кораблей в июле 2018 года и в этом году, в апреле. В будущем планируем применить ее и для пилотируемых запусков. Двухвитковая схема дает возможность в рекордно короткий срок доставлять на МКС экипажи и грузы. Но запуски по одновитковой схеме позволят нам достичь абсолютного рекорда. И у нас есть все условия, чтобы обеспечить первенство России в этом направлении, – отмечает заместитель руководителя Центра расчетно-теоретического обеспечения Рафаил Фарвазович Муртазин.

    Отработка одновитковой схемы может понадобиться и для реализации в будущем двухпусковых схем полета к Луне, предполагающих стыковку на околоземной орбите с разгонным блоком на низкокипящих компонентах топлива. Срок использования такого разгонного блока после выведения невелик, поэтому быстрое сближение и стыковка с ним – крайне актуальная задача. Ещё одна область применения быстрых схем сближения корабля со станцией – проведение спасательных операций в космосе, когда фактор времени может стать критическим.

    По мнению специалистов-баллистиков РКК «Энергия», реализовать одновитковую схему сближения возможно уже через 2-3 года.

    A $110 million NASA science instrument twice targeted for cancellation by the Trump administration is set for launch Tuesday inside the trunk of a SpaceX Dragon cargo capsule for delivery to the International Space Station, where it will spend three years charting changing carbon dioxide concentrations in Earth's atmosphere.

    Once mounted outside the space station's Kibo lab module, the instrument package will scan the planet between 52 degrees north and 52 degrees south latitude with the sensitivity to measure carbon dioxide levels to a precision better than one part per million, or within about 0.3 to 0.5 percent of the total carbon dioxide present in the atmosphere.

    The Orbiting Carbon Observatory-3, or OCO-3, instrument is a follow-up to NASA's OCO-2 satellite launched in 2014. OCO-2 was designed for a two-year mission, but continues collecting carbon dioxide data in its fifth year of operations.

    "The key motivation for the OCO-3 experiment is to continue this record of carbon dioxide," said Annmarie Eldering, OCO-3 project scientist at NASA's Jet Propulsion Laboratory in Pasadena, California. "OCO-2 was built to last two years, we've had it up there for four years, but there's always a risk it's not going to survive.

    "We'd like to have measurements that cover a long duration, and OCO-3 is going to help add to that record," Eldering said.

    OCO-3's high-resolution spectrometers are fitted to an Earth-pointing telescope with the ability to scan side-to-side, allowing the instrument to measure carbon dioxide in 50-mile by 50-mile (80-kilometer) squares in as little as two minutes. Within that zone, OCO-3 can collect a snapshot of carbon dioxide levels over 1-mile-wide (1.6-kilometer) footprints.

    The instrument will also observe faint light emitted by plants during photosynthesis, the process by which they convert light into energy, breathing in carbon dioxide and putting out oxygen. The light signal is called solar-induced fluorescence.

    "When plants are doing photosynthesis, they emit a little bit of light, and we can sense that light in our measurements," Eldering said. "So we have a measure of plant photosynthesis activity in combination with the carbon dioxide."

    Teams at JPL built OCO-3 around a spare instrument originally manufactured for OCO-2, but the new mission is more than a carbon copy, according to NASA scientists.
    Спойлер
    OCO-2 flies in a polar sun-synchronous orbit providing nearly global coverage, whereas the space station's orbit does not pass over the poles. OCO-2's orbit is timed to allow the spacecraft to fly over the same region of the planet in the early afternoon — roughly 1:30 p.m. local time — every day.

    The space station's orbit is not synchronized with the sun, allowing observations over time to cover the entire day, fr om sunrise to sunset.

    "That's really important because plants respond to sun, so we need to see them behaving across the day," Eldering said.

    "We can see how they're acting in the morning, at midday, what happens when it's really hot in the afternoon?" she said.

    And OCO-2 flies at an altitude of around 438 miles (705 kilometers), nearly 200 miles (300 kilometers) above the space station's orbit.

    "It is the same spectrometer (as OCO-2)," Eldering told reporters Monday. "The telescope is a little different because the orbit altitude is a little different."

    The OCO-3 mission cost around $110 million, including expenses to modify the already-built sensors for use on the space station, according to Eldering. NASA spent $467 million on the instrument, spacecraft and launch vehicle for the OCO-2 mission. Most of those expenses are not required for a hosted payload flying on the space station.

    NASA's efforts to establish a series of carbon dioxide-monitoring satellites have faced setbacks.

    The first Orbiting Carbon Observatory, or OCO-1, was lost in a launch failure on a Taurus XL rocket in 2009. The Obama administration approved the OCO-2 replacement mission, which launched in July 2014 on a Delta 2 booster, and the follow-on OCO-3 mission using spare hardware.

    Since the beginning of the Trump administration, the White House twice proposed eliminating OCO-3 fr om NASA's budget, along with other Earth science missions, including the Earth-facing instruments on the Deep Space Climate Observatory spacecraft stationed a million miles (1.5 million kilometers) fr om Earth.

    The Trump administration has also proposed cancelling the Plankton, Aerosol, Cloud, ocean Ecosystem, or PACE, satellite mission, and the Climate Absolute Radiance and Refractivity Observatory Pathfinder, or CLARREO Pathfinder mission, on three occasions. The White House's fiscal year 2020 budget proposal, released earlier this year, did away with the request to terminate funding for the OCO-3 and DSCOVR missions.

    Congress continued to fund OCO-3 and the other Earth science missions in fiscal year 2018 and 2019 budget bills signed by President Trump, keeping the projects alive.

    "Since about the start of the industrial revolution, we've seen CO2 levels in the atmosphere increase by about 30 percent," said Ralph Basilio, NASA's OCO-3 project manager at JPL. "Human activity is causing a tipping of the scales, this very fine delicate balance that we have in what we call the carbon cycle."

    "OCO-3 is going to specifically produce a dataset of carbon dioxide measurements," Basilio said. "We'd like to be able to keep an eye on this atmospheric CO2. Wh ere did it come from? Wh ere is it going? And how is it related to other global processes?"

    Carbon dioxide is a greenhouse gas, and scientists say rising levels of CO2 in the atmosphere caused by the burning of fossil fuels is driving temperatures warmer. Like its predecessor OCO-2, the OCO-3 instrument will seek to identify natural and human-made sources and sinks of carbon dioxide, places wh ere the gas is emitted into the atmosphere and ingested into plants and oceans.

    Eldering said plants and oceans take out about half of the carbon dioxide produced by human activity, dampening the impact of rising CO2 emissions. But there's some variability year-to-year.

    "We think it's tied to things like El Niño, drought, precipitation and temperature, but we really need to understand more if we want to predict accurately what will happen in the future," Eldering said. "We've got to understand these processes."

    Using the new targeted pointing capability, which is not available on the OCO-2 satellite, the OCO-3 instrument will take snapshots of carbon dioxide concentrations over the oceans, forested regions, volcanoes, cities and industrial zones, such as power plants.

    "This capability of OCO-3 to map out some of those areas and start to see some change over time, that really is how we're going to advance our understanding and our modeling for the future of understanding our climate," Eldering said.

    OCO-3's ability to measure carbon dioxide at all times of the day will also help scientists collect more observations without interference from clouds, which are more prevalent in the afternoon, when OCO-2 flies overhead.

    "For example, the vast carbon stores of the rapidly changing Amazon rainforest are a critical part of Earth's carbon cycle, but when OCO-2 flies over the forest at about 1:30 p.m., afternoon clouds have usually built up, hiding the region from the instrument's view," NASA said in a press release. "OCO-3 will pass the Amazon at all times of day, capturing far more cloud-free data.

    In the above video, scientists used data from NASA's OCO-2 satellite to create a model of carbon dioxide motion in the atmosphere from Sept. 1, 2014, to Aug. 31, 2015.

    The OCO-3 instrument is about the size of a refrigerator. The package will ride to the space station in the rear payload bay of a SpaceX Dragon cargo capsule set for launch Tuesday from Cape Canaveral.

    Assuming an on-time launch, the robotic cargo carrier is scheduled to arrive at the space station next Thursday, May 2. Several days later, the station's Canadian-built Dextre robot will pull the instrument from the Dragon spacecraft's unpressurized trunk and hand it off to a Japanese robotic arm, which will position OCO-3 on the external science deck outside of the station's Kibo lab module.

    After activation, OCO-3 is designed to collect carbon dioxide data for at least three years, and it requires no assistance from the astronauts living on the space station.

    OCO-3 will be joined in the Dragon's trunk by a pallet sponsored by the U.S. military's Space Test Program containing multiple experiments for the Defense Department, NASA and university researchers. The STP-H6 payload will also be mounted outside the space station to conduct its investigations, which include an X-ray communications experiment that could prove useful for deep space probes and hypersonic missiles.

    Several tons of food, experiments and supplies will also ride to the station inside the Dragon capsule's pressurized compartment.

    NASA astronaut Christina Koch works on the COLBERT treadmill inside the Tranquility module.

    The six-member Expedition 59 crew conducted a routine, periodic drill for response to emergencies today in the middle of a science-packed day. The astronauts also researched space biology while preparing for next week's SpaceX Dragon cargo mission.

    The space residents practiced communications, roles and responsibilities, and evacuating the station in the unlikely event of an emergency. The crew would split up, board their Soyuz spacecraft and undock quickly for a ride back to Earth. The two Soyuz crew ships docked to the International Space Station each hold three crewmembers.

    NASA Flight Engineers Nick Hague and Anne McClain set up the ultrasound and optometry instruments today for more Fluid Shifts studies. Flight surgeons are exploring what happens to an astronaut's veins and eyes due to the head-ward flow of fluids caused by microgravity.

    Hague later checked out command and communications gear he and astronaut David Saint-Jacques will use when the SpaceX Dragon resupply ship arrives next week. Saint-Jacques will command the Canadarm2 robotic arm to capture Dragon early Friday, May 2, two days after it launches from Florida. Hague will monitor Dragon's telemetry during its approach and rendezvous. NASA TV is broadcasting the pre-flight activities and mission events live.

    Saint-Jacques and Flight Engineer Christina Koch also split the day feeding mice and cleaning cages for the Rodent Research-12 experiment. The study is investigating the immune system's response to the conditions of long-term spaceflight.

    Commander Oleg Kononenko focused much of his attention today on life support maintenance in the Russian segment of the orbital lab. Flight Engineer Alexey Ovchinin studied ways to maximize the effectiveness of exercise in the weightless environment of microgravity.

    Российские ученые напечатают в космосе мясо и рыбу на биопринтере

    В проекте задействованы лаборатории из США и Израиля

    МОСКВА, 26 апреля. /ТАСС/. Российские ученые совместно с коллегами из Израиля и США планируют в сентябре направить на Международную космическую станцию (МКС) клеточный материал мяса и рыбы, чтобы космонавты напечатали образцы в 3D-биопринтере. Об этом журналистам сообщил в пятницу управляющий партнер лаборатории биотехнологических исследований 3D Bioprinting Solutions Юсеф Хесуани.

    "В сентябре будут направлены [на МКС] мышечные клетки. Это проекты, которые мы делаем совместно с двумя лабораториями из США и одной - из Израиля. Коллеги из Израиля поделятся с нами [имеющимся у них] клеточным материалом - там будет крупный рогатый скот. Американские коллеги передают нам клетки рыбы - нескольких пород рыб", - сказал Хесуани и отметил также, что с зарубежным клеточным материалом будет проведен еще ряд наземных экспериментов.

    Еще один эксперимент в космосе будет проведен в августе. "Будут эксперименты и с живыми материалами, и с неживыми материалами - кристаллами, аналогом костной ткани (кальция фосфат). Мы будем отправлять бактерии для формирования биопленки, для изучения после того, как они приземлятся, эффектов антибиотикорезистенции", - уточнил Хесуани и добавил, что также будут печататься клетки костной ткани человека, клетки хрящевой ткани и клетки щитовидной железы мыши.

    После усовершенствования кюветы (прибора, где происходит сборка микроорганов при 3D-печати), создание и наземные испытания которой проходят на Земле, планируется печать трубчатых органов в 3D-биопринтере на Международной космической станции. "У нас магнитно-акустические системы должны полетать в 2020 году. Будем печатать трубчатые структуры - мочеточник, уретру, сосуды", - сказал Хесуани.

    A Look at the Science Ahead for Christina Koch and Andrew Morgan

    NASA is fine-tuning plans for two extended duration expeditions for astronauts who launch to space this year. One month after her arrival on the International Space Station, NASA astronaut Christina Koch got word she will stay in space just short of a year, and her colleague Andrew Morgan, who launches on his first flight on the 50th anniversary of the first human Moon landing, also will stay in space longer than the typical six-month mission.

    "One month down, ten to go," Koch tweeted Wednesday morning after receiving the news. "Today the possibility has become a reality."

    Koch arrived on board the space station March 14, beginning scientific research activities as part of the Expedition 59 crew. She's now scheduled to remain in orbit until February 2020, spanning Expedition 59, 60 and 61.
    Спойлер
    "I still have the grin on my face that won't seem to go away just that I'm here," Koch said. "To walk into the actual reality of the space station, the fact that it actually exists, was like walking into a movie set." 

    Her mission will set a record for the longest single spaceflight by a woman, eclipsing the previous mark set by Peggy Whitson of 288 days on Expeditions 50 through 52 in 2016-2017.

    "It's an honor to follow in Peggy's footsteps," Koch said. "Peggy has been a mentor and a heroine of mine for many, many years. I hope that me being up here and giving my best every day is a way for me to say thank you to people like her, who not only paved the way through their examples, but actively reached out to make sure we could be successful."

    Koch's planned mission duration will be just shy of the longest single spaceflight by a NASA astronaut, 340 days set by former NASA astronaut Scott Kelly during his one-year mission in 2015-2016. Koch's mission will provide researchers the opportunity to observe effects of long-duration spaceflight on a woman to complement the data from Kelly's mission. Both represent exciting opportunities for NASA's Human Research Program and the work to prepare for human missions to the Moon and Mars.

    "Astronauts demonstrate amazing resilience and adaptability in response to long duration spaceflight exposure," said Jennifer Fogarty, chief scientist of the Human Research Program at NASA's Johnson Space Center. "These opportunities have also demonstrated that there is a significant degree of variability in the responses of humans to spaceflight, and it is important to determine the acceptable degree of change for both men and women."

    The majority of data available is on male astronauts; however, male and female bodies respond differently, and health conditions occur at different rates in male and female populations. Some studies, including one led by NASA researcher Steven Platts, have found that women are more likely than men to experience faintness as a result of "orthostatic hypotension," a cardiovascular issue. Men, on the other hand, appear more prone to vision changes caused by spaceflight associated neuro-ocular syndrome (SANS).

    Koch's mission is an exciting opportunity to gather extended duration biomedical data to enable missions to the Moon and Mars. Although with a different research portfolio than Kelly's one-year mission and the Twins Study or Whitson's previous record setting missions, Koch will participate in some studies in which Whitson also participated, including the Functional Immune and Food Acceptability studies. Scott Kelly also participated in a study on functional immunity. Integrating her extended-duration studies with those of Kelly and Whitson will enable researchers to better understand astronaut adaptability over long periods of space exposure and better support the development of effective countermeasures to maintain crew health.

    Several studies planned during Koch's stay on the station will come from NASA's international partners. Collaborative research enables NASA and its international partners to develop innovative measures to protect astronauts and mitigate the effects of spaceflight hazards.

    Morgan also will have an extended-duration expedition on the station in his career-first spaceflight. He is set to launch July 20 aboard the Soyuz MS-13 with crewmates ESA (European Space Agency) astronaut Luca Parmitano, and Roscosmos cosmonaut Alexander Skvortsov. NASA sel ected Koch and Morgan in the same astronaut class in 2013.

    "I've been preparing for this mission for almost six years, and I'm ready to do what the station program has asked of me," Morgan said. "I've been mentally prepared for the idea of my mission being extended for a little while now, so my family and I are ready to take on this very exciting challenge."
    [свернуть]
    Morgan is scheduled to return to Earth aboard Soyuz MS-15 in March 2020 with NASA astronaut Jessica Meir and Russian cosmonaut Oleg Skripochka.
    Спойлер
    "This is exactly what we've trained for," Morgan said. "Might as well jump into the deep end and do all nine months right up front."

    "Any time you increase the diversity of a pool of folks participating in any of those human research studies, you make the results of those studies more robust," Koch said. "We're happy to be participating in those and to get the numbers up."

    Meanwhile, NASA's Human Research Program continues to lay the groundwork for future one-year missions on the space station and has sel ected 25 proposals to investigate biological, physiological, and behavioral adaptations to spaceflight. With information gained fr om the selected studies during future one-year missions, NASA aims to address five hazards of human space travel: space radiation, isolation and confinement, distance fr om Earth, gravity fields (or lack thereof), and hostile/closed environments that pose great risks to the human mind and body in space.

    A week after a test-firing of SpaceX's new crew capsule went awry, SpaceX successfully completed a hold-down firing of its next Falcon 9 launcher Saturday morning at Cape Canaveral in preparation for a predawn liftoff Wednesday carrying several tons of food, supplies and experiments to the International Space Station.

    The Falcon 9 rocket, without its Dragon cargo capsule, ignited nine Merlin 1D first stage engines at 10 a.m. EDT (1400 GMT) Saturday, sending a plume of exhaust into the air as the kerosene-fueled powerplants ramped up to full throttle, producing 1.7 million pounds of thrust.

    SpaceX confirmed a good test in a tweet soon after the hold-down firing.

    Hold-down restraints kept the Falcon 9 rocket firmly on the ground during the test, which lasted several seconds. SpaceX will lower the Falcon 9 rocket at the Complex 40 launch pad and return it to a nearby hangar for attachment with the Dragon spacecraft, which is being reused after a previous trip to the space station.
    [свернуть]
    The Falcon 9 and return will roll back to the pad next week in preparation for liftoff Wednesday, May 1, at 3:59 a.m. EDT (0759 GMT), roughly the moment Earth's rotation brings the launch pad under the space station's orbital plane.
    Спойлер
    SpaceX plans to land the Falcon 9's first stage on a drone ship in the Atlantic Ocean approximately 17 miles (28 kilometers) southeast of the launch pad, or due east from the easternmost point of Cape Canaveral.

    SpaceX's Landing Zone 1, a former Atlas launch pad at Cape Canaveral Air Force Station, was the site of the April 20 explosion of a Crew Dragon spacecraft during ground testing. Investigators and ground teams are safing the site after the accident, and collecting evidence to help determine the cause of the mishap, which dealt a major setback to the commercial crew capsule program developed in partnership between SpaceX and NASA.

    The accident prompted SpaceX to move the landing of the rocket on the next Falcon 9 launch from the onshore facility to the offshore drone ship. Resupply missions to the space station do not require all of the Falcon 9's lift capacity, leaving enough fuel in the first stage to reverse course and return to Cape Canaveral, so the drone ship will be positioned just off the coast, not the more typical distance of several hundred miles downrange.

    NASA and SpaceX officials are assessing whether last weekend's accident may raise any concerns about the next Dragon resupply mission, according to members of NASA's Aerospace Safety Advisory Panel. But the Dragon cargo craft is much different from the Crew Dragon, and the accident April 20 occurred during a hotfire test of the crew capsule's SuperDraco abort engines, which are not used on Dragon spacecraft set for liftoff next week.

    SpaceX is pressing ahead with preparations for Wednesday's launch, but the Crew Dragon accident could again be discussed by senior managers during a launch readiness review planned for Tuesday.

    The mission was previously slated for liftoff Tuesday, following a test-firing of the Falcon 9's engines Friday. But the static fire was delayed to Saturday for unspecified reasons — SpaceX does not usually discuss the timing of pre-launch hotfire tests before they are completed — forcing a one-day delay in the launch to Wednesday.

    A forecast issued Friday by the U.S. Air Force's 45th Weather Squadron predicted an 80 percent probability of favorable weather conditions for a predawn launch Wednesday.

    Assuming the Falcon 9 takes off Wednesday, the Dragon supply ship is due to reach the space station early Saturday. The station astronauts will grapple the Dragon cargo freighter using the orbiting lab's Canadian-built robotic arm, then move the supply ship to a berthing port for a stay planned to last around one month.

    While astronauts unpack the food, provisions and biological experiments carried inside Dragon's pressurized compartment, robotic arms outside the station will retrieve a pair of instrument packages to be mounted on science decks outside the complex.

    One of the experiments, developed by NASA's Jet Propulsion Laboratory, will measure the amount of carbon dioxide in Earth's atmosphere over a three-year mission. Scientists want to extend a record of space-based carbon dioxide measurements begun in 2014 by NASA's Orbiting Carbon Observatory satellite mission, which has exceeded its design life.

    Another external unit inside Dragon managed by the U.S. military's Space Test Program hosts several investigations, including a novel X-ray communications experiment developed by NASA and the Naval Research Laboratory. X-ray signals could provide a new way to communicate with deep space probes or hypersonic missiles in flight, according to scientists.

    Wednesday's launch will be SpaceX's fifth mission of the year, and the fifth launch overall from Cape Canaveral so far in 2019.
