Глава НАСА обещал узнать, есть ли в России запрет на темнокожих космонавтов

Так Брайденстайн ответил на вопрос модератора сессии, который предположил, что именно российская сторона стоит за тем, что ни один афроамериканец не был в космосе с 2011 года после закрытия программы запуска американских шаттлов.


"Пятьдесят два астронавта были запущены русскими. Что интересно: ни один из них не был афроамериканцем. То есть с 2011 года ни один афроамериканец от НАСА не был на орбите. Это должно было измениться в минувшем июне. Джанетт Эппс должна была полететь... Она была исключена из этой миссии... И это поднимает вопрос: что происходит? Русские что, отказываются запускать афроамериканских астронавтов?" — спросил он.

Воспитанники "Сириуса" вышли на связь с экипажем МКС на космическом уроке

Космос | 23 июля, 22:24 UTC+3

СОЧИ, 23 июля. /ТАСС/. Воспитанники образовательного центра "Сириус" провели сеанс связи с космонавтами Роскосмоса, находящимися на борту Международной космической станции, Олегом Артемьевым и Сергеем Прокопьевым. Космический урок состоялся в рамках проектной смены "Большие вызовы - 2018", которая объединила 400 школьников из 56 регионов России.

"Наше партнерство дает такие удивительные результаты. Все, кто здесь находится, - это победители и финалисты конкурса проектных работ, который проводится практически по всем регионам <...> Задачу и проблематику мы создавали вместе с партнерами, специалистами госкорпорации "Роскосмос", <...> мы выделили отдельное направление - космические системы", - открыла космический урок руководитель образовательного фонда "Талант и успех", который курирует работу центра, Елена Шмелева.

В Роскосмосе напомнили, что юные исследователи "Сириуса" разработали при поддержке экспертов (РКК "Энергия", НИИЯФ МГУ и компании "Спутникс" ) два наноспутника - "СириусСат-1" и "СириусСат-2". Аппараты запустили вместе с транспортным грузовым кораблем "Прогресс МС-09" 10 июля 2018 года, космонавты их уже получили. Поэтому первый вопрос школьники задали о том, как будет происходить запуск спутников в открытый космос, который намечен на август.

Артемьев уточнил, что запуск спутников запланирован на 15 августа. "У нас будет выход 15 августа в период нашей экспедиции. Мы будем запускать ваши спутники <...> против вектора скорости <...> Мы должны запустить спутники как можно ближе между собой <...> Я думаю, что у нас все получится", - сказал космонавт.

Подростки обсудили с космонавтами, какие проекты в области малых спутников самые перспективные, как правильно убирать космический мусор, и каково предназначение спутников-инспекторов.

Генеральный директор Роскосмоса Дмитрий Рогозин рассказал журналистам о космических технологиях, над которыми работают воспитанники "Сириуса". "Сегодня показывали интересные технологии, связанные с созданием лунного бура. Это возможность использовать бурение реголита на глубину до 4 м. Мы вполне с удовольствием ее возьмем, и я порекомендую её к адаптации, к созданию конкретного аппарата", - отметил Рогозин.

Rodent Research Seeks to Benefit Astronauts and Earthlings

Mark Garcia
Posted Jul 24, 2018 at 1:33 pm


NASA astronaut Drew Feustel works inside the Microgravity Science Glovebox inspecting mice being observed as part of the Rodent Research-7 experiment.

Life science took precedence today aboard the International Space Station as the crew explored how microgravity impacts rodent physiology. The space research can help scientists improve astronaut health and treat humans on Earth.

Спойлер

Four Expedition 56 crew members worked together throughout the day examining mice for the Rodent Research-7 study. The experiment observes how microbes affect the gastrointestinal, immune, metabolic, circadian, and sleep systems. Results may help doctors implement programs to keep astronauts healthy on deep space missions. Patients on Earth may also benefit from newer advanced therapies that treat internal disorders.

Commander Drew Feustel joined Flight Engineers Serena Auñón-Chancellor, Ricky Arnold and Alexander Gerst for the rodent study on Tuesday. The orbital lab researchers examined bone structure, collected blood samples and processed and stowed biological samples in science freezers.

Those samples will be returned to Earth inside the SpaceX Dragon cargo craft Aug. 3 for analysis on Earth. Dragon will be packed with station hardware and research gear when it splashes down in the Pacific Ocean. It will be retrieved by SpaceX and NASA personnel for examination by engineers and scientists.

ISS Daily Summary Report – 7/20/2018

Micro-11:

Спойлер

Today the crew performed two sessions for the Micro-11 investigation. They checked out, configured and calibrated the Micro-11 microscope, thawed samples removed fr om a General Laboratory Active Cryogenic ISS Experiment Refrigerator (GLACIER), fixed those samples and loaded them into the microscope for imaging. Afterwards, they ins erted the samples into a Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). There are a total of thirteen runs for the Micro-11 investigation. Micro-11 examines whether spaceflight alters human sperm, by tracking the swimming patterns of human and bull sperm during spaceflight. This investigation also assesses other aspects of sperm functionality related to male fertility. As a result, Micro-11 provides fundamental data indicating whether successful human reproduction beyond Earth is possible, and whether countermeasures are needed to protect sperm function in space.

РКК «Энергия»: аппаратура для выращивания человеческих тканей готова к отправке на МКС
25.07.2018

Аппаратуру для проведения первого российского коммерческого эксперимента «Магнитный 3D-биопринтер», подготовка которого осуществляется в тесном сотрудничестве со специалистами Роскосмоса, РКК «Энергия» и ЦНИИмаш, планируется отправить на МКС осенью этого года.

Заявитель эксперимента - лаборатория биотехнологических исследований «3D Биопринтинг Солюшенс» - российский стартап, являющийся «дочкой» компании «Инвитро». Впервые в России организация-заявитель сама оплачивает создание и испытание научной аппаратуры.

3D-биопринтер создан для выращивания тканей, а впоследствии и органов. Также он может быть использован для изучения влияния факторов космического пространства на живые объекты при дальних полетах: выращенные в космосе из настоящих клеток образцы кожи, внутренние органы и т.д.

Спойлер

- Нашей задачей было оценить техническую реализуемость данного эксперимента, обеспечить контроль над подготовкой необходимой аппаратуры – самого принтера и кювет для биоматериала – к условиям доставки на орбиту и полученных результатов – обратно. Помимо этого специалисты РКК «Энергия» организовали весь комплекс необходимых сертификационных процедур для такого рода оборудования в соответствии с действующими на МКС международными правилами по безопасности, - рассказал заместитель руководителя научно-технического центра РКК «Энергия» Дмитрий Сурин.

Уже изготовлено два комплекта аппаратуры. Один – опытный образец - уже прошел все необходимые наземные автономные испытания в «Энергии» и Институте медико-биологических проблем РАН. Второй – тренажерный образец - использовался в процессе подготовки членов экипажей: основного (Алексей Овчинин) и дублирующего (Олег Кононенко). Тренировки в ЦПК с участием специалистов «3D Биопринтинг Солюшенс» и РКК «Энергия» уже завершены, все замечания и предложения космонавтов будут учтены.

Третий - лётный - образец аппаратуры для эксперимента «Магнитный 3D-биопринтер» готовится к отправке на МКС осенью. Кюветы будут заправлены химическими реактивами, необходимыми для фабрикации и последующего фиксирования выращенного материала, а также биообразцами, из которых будет выстраиваться конечная структура. По итогам первого этапа эксперимента ученые планируют получить образцы размером в 2-3 мм. Планируется, что это будет хрящевая ткань человека и щитовидная железа грызуна.

Биологические образцы очень чувствительны к времени хранения, поэтому эксперимент необходимо начать непосредственно после прибытия космонавтов и аппаратуры на МКС. Результаты эксперимента должны вернуться на Землю зимой этого года. Встречать прибывшие с орбиты биообразцы будет специалист РКК «Энергия», который обеспечит их оперативную доставку биологам – заявителям эксперимента.

В дальнейшем биопринтер может использоваться как заявителями эксперимента, так и сторонними научными коллективами. Его назначенный срок службы – пять лет.

Говоря о принципе работы 3D-биопринтера, стоит отметить, что это название является довольно условным: у устройства нет никаких движущихся частей, и процесс выращивания материала происходит не аддитивно, то есть послойно, а с использованием «формативного» принципа, когда образец растёт в сильном магнитном поле в условиях микрогравитации. Внутри прибора установлены камеры GoPro, с помощью которых можно наблюдать за ходом эксперимента.

В перспективе эта методика может применяться для создания органов из доставленных на орбиту биоматериалов конкретных пациентов. У такого способа сразу два очевидных преимущества: не надо ждать, когда появится подходящий для пересадки донорский орган, и автоматически решается вопрос приживаемости. Еще одно возможное применение биопринтера – выращивание белковой пищи, например космического «фарша», который будет продолжать расти по мере его употребления.

Биофабрикацией по предлагаемой технологии можно заниматься и на Земле, однако такая установка была бы очень громоздкой и требовала бы значительных материальных и энергозатрат, – по некоторым оценкам, ее энергопотребление сравнимо с небольшим городом.

Posted Jul 26, 2018 at 1:46 pm


Flight Engineer Serena Auñón-Chancellor conducts research operations for the AngieX Cancer Therapy study inside the Microgravity Science Glovebox. The new cancer research seeks to test a safer, more effective treatment that targets tumor cells and blood vessels.

The International Space Station got an orbital boost today to position itself for a crew swap taking place later this year. Inside the lab complex, the current residents spent their time today exploring a diversity of phenomena impacted by long-term exposure to microgravity.

Спойлер

A docked Russian Progress 69 resupply ship fired its engines this morning slightly increasing the space station's orbital altitude to enable the departure and arrival of a pair of Soyuz crew ships this autumn. Three Expedition 56 crew members will return to Earth Oct. 4 inside the Soyuz MS-08 spacecraft. They will be replaced a week later by two new Expedition 57 crew members when they dock inside the Soyuz MS-10 spacecraft.

NASA astronauts Drew Feustel and Serena Auñón-Chancellor continued a second week of research operations to gain fundamental data about fertility in space. The duo examined biological samples in a microscope and stowed them in a science freezer for later analysis. The Micro-11 study is exploring the possibility of human reproduction in space including ways to address aging problems on Earth.

Alexander Gerst, of the European Space Agency, explored the sedimentary properties of quartz and clay particles. The German astronaut mixed quartz and clay samples suspended in a liquid for photographic and video downlink to scientists on Earth. Observations can help guide future geological studies of unexplored planets and improve petroleum exploration here on Earth.

Expedition 56 Flight Engineer Ricky Arnold of NASA split his time working on a variety of science gear that examines different microscopic properties. He set up Aerosol Samplers in the Harmony and Tranquility modules to collect airborne particles in the station's air cabin for analysis. Arnold later stowed a Biomolecule Sequencer he used this month to sequence DNAextracted from microbes living on space station surfaces.

Horizons science – airway monitoring

European Space Agency, ESA

Опубликовано: 26 июл. 2018 г.

In space, there is no such thing as waiting for the dust to settle. Rather than drifting to the ground, dust particles float about continuously and can irritate eyes and lungs.

By recording how much nitrogen oxide he exhales in space as part of the Airway Monitoring experiment, ESA astronaut Alexander Gerst is helping researchers understand how to monitor, diagnose and treat lung conditions like asthma here on Earth.

The findings of this monitoring will also be crucial to exploring the Moon and even Mars – where dust is considered even more toxic and must be carefully managed for astronauts' health.

The Airways Monitoring experiment has been underway since 2015. Later in the Horizons mission Alexander will repeat the experiment in the reduced pressure of the airlock.

Micro-11 examines whether spaceflight alters human sperm, by tracking the swimming patterns of human and bull sperm during spaceflight. This investigation also assesses other aspects of sperm functionality related to male fertility. As a result, Micro-11 provides fundamental data indicating whether successful human reproduction beyond Earth is possible, and whether countermeasures are needed to protect sperm function in space.

Microgravity Investigation of Cement Solidification (MICS):

Спойлер

The crew transferred a MICS ampoule kit to the ISS Portable Glovebag and broke the seal between the upper and center ampoules and mixed the contents in the ampoules with a spatula. They then returned each sample bag to the kit bag. The MICS investigation supports the evaluation of microstructure and material properties of benchmark cement samples. Different responses to thermal and mechanical loading are expected and will be characterized in detail. Positive attributes found in the hardening process due to the microgravity environment aboard the ISS will be reported with the intent of improving Earth-based cement and concrete processing.

Aerosol Samplers:

Спойлер

Today the crew deployed Active Aerosol Samplers (AASs) in Nodes 2 and 3. The battery-powered AASs actively pull in air and collect particles using the principal of thermophoresis. This is accomplished by flowing the sampled air through a large thermal gradient in a narrow channel. During this process, particles are driven to the cold side of the channel, wh ere an electron microscope (EM) grid is held in place by a tiny magnet. When returned to Earth, these grids are easily removed and placed directly in an EM for analysis.

Binary Colloidal Alloy Test – Cohesive Sediment (BCAT-CS):

Спойлер

This morning the crew deployed an AC Inverter in the Japanese Experiment Module (JEM) to support BCAT operations. They then se t up the BCAT-CS hardware and mixed all ten samples, while taking manual photos and initiating automated photography utilizing the camera intervalometer. The Camcorder will provide live high-definition video to the ground. BCAT-CS focuses on the study of forces between particles that cluster together by using sediments of quartz and clay particles. Conducting the research in the microgravity environment of the ISS makes it possible to separate the forces acting on the particles over a short range (adhesive forces) versus those acting over a long range (cohesive forces). The quartz/clay system is commonly found in a wide variety of environmental settings (such as rivers, lakes, and oceans) and plays an important role in technological efforts related to deep-sea hydrocarbon drilling and carbon dioxide sequestration.

Radiation Dosimetry Inside ISS-Neutron (RaDI-N):

Спойлер

Today a USOS crewmember retrieved 8 bubble detectors from deployed locations in Node 3 and handed them over to a Russian crewmember, who will process all the detectors in the Bubble Reader. This Canadian Space Agency investigation measures neutron radiation levels in the ISS. Bubble detectors are designed to only detect neutrons and ignore all other radiation.

Food Acceptability:

Спойлер

Two crewmembers completed Food Acceptability questionnaires today. The Food Acceptability investigation seeks to determine the impact of repetitive consumption of food currently available from the spaceflight food system. Results will be used in developing strategies to improve food system composition to support crew health and performance on long duration missions.

Team Task Switching (TTS):

Спойлер

A crewmember completed a TTS survey today. When crewmembers are required to switch their attention between tasks frequently, performance on each of the tasks can be negatively affected. The objective of the TTS investigation is to gain knowledge about whether or not crew members have difficulty in switching tasks and determine the impacts of these switches, in order to both reduce any negative consequences and improve individual and team motivation and effectiveness.

Common Berthing Mechanism (CBM) Controller Panel Assembly (CPA) 4 Cable Checkout:

Спойлер

Last week, the crew replaced a damaged CBM CPA Latch 4 Actuator Cable.  Today the crew re-installed the affected CBM CPA and performed a checkout using this new cable, ensuring proper operation prior to Dragon unberth on 3 August.

Compound Specific Analyzer-Combustion Products (CSA-CP) Extended Maintenance:

Спойлер

Today the crew discharged the old CSA-CP batteries for disposal and performed a battery change-out in all units. Once the new batteries were installed, all units were zero calibrated and deactivated. The CSA-CPs are used onboard the ISS to indicate the presence of a fire or pre-ignition and indicate when toxic gas levels have subsided and it is safe for the crew to re-enter the affected area.

Сегодня ровно 50 дней моей жизни вне Земли! Хотя "день" на борту нашего "космического дома" - понятие условное. МКС, вращаясь вокруг Земли, встречает рассвет 16 раз в сутки. Всего полтора часа разделяют рассвет и закат из окна иллюминатора. Вот где романтика!

NASA astronaut Ricky Arnold processes microbial DNA using the Biomolecule Sequencer, a device that enables DNA sequencing in microgravity, to identify microbes able to survive in microgravity.

A trio of studies taking place today aboard the International Space Station explored a potential cancer therapy, researched human reproduction and observed protein crystals. Eye exams were also on the schedule to understand how microgravity impacts vision.

NASA astronaut Serena Auñón-Chancellor started her morning peering at endothelial cells through a microscope for the AngieX Cancer Therapy study. Afterward, she moved on to the Micro-11 investigation examining more biological samples in a microscope to gain fundamental data about successful reproduction in space.

Alexander Gerst, of the European Space Agency, contributed to pharmaceutical research during the afternoon stowing protein molecules in a science freezer. Microgravity enables the growth of high quality protein crystals revealing structures and properties that could improve disease-fighting therapies on Earth.

Gerst first started his day scanning NASA astronaut Ricky Arnold's for eyes using Optical Coherence Tomography, a light imaging technique analogous to ultrasound. The data helps doctors understand how the weightless environment of microgravity impacts vision so mission controllers can plan safer spaceflight missions.
