ISS Daily Summary Report – 2/24/2020

OsteoOmics:

The crew retrieved six BioCells from the BioCell Habitat and placed them into Cold stowage. The empty habitat was temp stowed for later use. The crew also removed the Thaw Media Bag from cold stowage in preparation for upcoming OsteoOmics operations. Millions of Americans experience bone loss, which results from disease or the reduced effects of gravity that can occur in bed-ridden patients. OsteoOmics tests whether magnetic levitation accurately simulates the free-fall conditions of microgravity by comparing genetic expression osteoblastic cells, a type of bone cell, levitated in a high-field superconducting magnet with cells flown in low-Earth orbit. This information helps scientists determine the molecular and metabolic changes that take place in magnetic levitation and real microgravity.

Fluid Shifts:

The crew performed Blood, Urine and Saliva collections in support of the Dilution Measures study for the Fluid Shifts experiment. Fluid Shifts is a NASA investigation, divided into Dilution Measurements, Baseline Imaging, and Imaging with Chibis. The Chibis hardware is used to perform the Lower Body Negative Pressure (LBNP) part of the experiment. The Fluid Shifts experiment investigates the causes for severe and lasting physical changes to astronaut's eyes. Because the headward fluid shift is a hypothesized contributor to these changes, reversing this fluid shift with a LBNP device is being evaluated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and prevention of eye damage.

STaARS BioScience-9:

The crew retrieved five STaARS BioScience-9 samples and placed them into the Kynar Bag which was placed into temporary stowage. The samples will be periodically removed and placed into cold stowage. Tapping Microgravity to Enhance Biofuel Production (STaARS BioScience-9) aims to identify novel biological mechanisms using genetically modified Escherichia coli (E. coli) to improve the bio-production of isobutene to an extent that economically competes with petrochemical production processes.

Источник: подготовка МКС к стыковке модуля "Наука" переложена на другую экспедицию
Такое решение было принято после переноса запуска МЛМ на конец 2020 года

МОСКВА, 26 февраля. /ТАСС/. Готовить Международную космическую станцию (МКС) к стыковке многофункционального лабораторного модуля (МЛМ) "Наука" будет экспедиция МКС-64, а не МКС-63, как планировалось ранее. Об этом сообщил ТАСС источник в ракетно-космической отрасли.

"С экспедиции МКС-63 эти задачи сняли, переложили на 64", - сказал собеседник агентства.

По его словам, такое решение было принято после переноса запуска МЛМ на конец 2020 года (в мае 2019 года генеральный директор Роскосмоса Дмитрий Рогозин сообщил о переносе запуска модуля с лета на конец 2020 года). Космонавтам предстоит освободить стыковочный узел для приема нового модуля во время выхода в открытый космос, также они заменят блоки ряда систем и установят новое программное обеспечение, чтобы бортовой компьютер распознал "Науку" в составе станции.

Ранее другой источник рассказал ТАСС, что для подключения "Науки" после ее стыковки с МКС российские космонавты протянут силовой кабель из американского сегмента через функционально-грузовой блок "Заря" и служебный модуль до МЛМ. Эти работы начали проводить космонавты Федор Юрчихин и Александр Мисуркин во время выхода в открытый космос в 2013 году.

Генеральный директор Роскосмоса Дмитрий Рогозин ранее в интервью ТАСС сообщил, что запуск модуля "Наука" состоится в конце 2020 - начале 2021 года, если его доставят на Байконур в марте. Позже глава Центра им. М. В. Хруничева Алексей Варочко уточнил, что предприятие планирует 19 марта отправить МЛМ на космодром.

МЛМ способен вырабатывать кислород на шесть человек, регенерировать воду из урины. С "Наукой" российские космонавты должны получить второй туалет, каюту для третьего члена экипажа, а также европейский манипулятор ERA, который позволит выполнять ряд работ без выхода в открытый космос.

Замена нового экипажа

В апреле в составе экспедиции МКС-63 на Международную космическую станцию должны были полететь российские космонавты Николай Тихонов и Андрей Бабкин, а также американский астронавт Крис Кэссиди. На прошлой неделе исполнительный директор Роскосмоса по пилотируемым космическим программам Сергей Крикалев сообщил, что из-за медицинских показаний российская часть экипажа "Союза МС-16", вероятно, будет заменена на дублеров - Анатолия Иванишина и Ивана Вагнера.

Dragon Launch Set for March 6, Station Bone Research Benefits Earth

Mark Garcia
Posted Feb 25, 2020 at 6:13 pm


The SpaceX Dragon resupply ship launches Dec. 5, 2019, atop the Falcon 9 rocket on its last mission from the Kennedy Space Center in Florida.

SpaceX has announced March 6 for the launch of its 20th contracted cargo mission to the International Space Station. Its Dragon resupply ship will arrive March 9 with over 5,600 pounds of science hardware, research samples and supplies to the Expedition 62 crew.

Meanwhile, NASA Flight Engineers Jessica Meir and Andrew Morgan are tending to a new experiment, which was delivered early last week aboard Northrop Grumman's Cygnus cargo craft. The astronauts are exploring the differences between bone cells exposed to microgravity versus samples magnetically levitated on Earth.

Doctors will use the comparisons to gain a deeper understanding of bone diseases. Space-caused bone loss is similar to the symptoms of Earth-bound conditions such as osteoporosis. Astronauts exercise daily keeping track of their diet to counteract the effects of microgravity and maintain healthy bones and muscles.

Meir and Morgan continue to unpack the over three tons of cargo shipped aboard Cygnus one week ago. The duo transferred powered payloads including science freezers containing research samples and tanks filled with nitrogen and oxygen to replenish the station's atmosphere.

Commander Oleg Skripochka of Roscosmos was back on space physics research this morning observing the behavior of heavily charged particles, or plasma crystals. The three-time station resident also serviced life support gear before collecting measurements from Russian radiation detectors.

From top to bottom, NASA Flight Engineers Andrew Morgan and Jessica Meir and Roscosmos Commander Oleg Skripochka pose for a playful portrait.

The three-member Expedition 62 crew split its time today between biomedical studies and space physics. The microgravity research aboard the International Space Station helps scientists, doctors and engineers provide unique solutions that could improve life for humans on Earth and in space.

Astronauts living in space experience a condition that mimics osteoporosis on Earth. The lack of gravity quickly weakens a crewmember's bones unless they counteract it with daily exercise and proper nutrition. This is one of many challenges NASA faces as it plans to send humans to the Moon, Mars and beyond.

NASA astronauts Jessica Meir and Andrew Morgan this week are helping doctors to compare bone cells in space with samples on Earth that are levitated magnetically. The observations from the OsteoOmics-02 study could provide deeper insights into bone ailments on Earth, including osteoporosis.

Meir also serviced a 3D bioprinter today replacing components inside the device that manufactures complex organ structures aboard the orbiting lab. She later joined Morgan for more eye checks this week using optical coherence tomography in the station's Harmony module.

On the Russian side of the orbiting complex, station Commander Oleg Skripochka continued exploring plasma physics. The veteran cosmonaut set up a device that traps clouds of particles creating plasma crystals and observes their dynamics. At the end of the day, he swapped out a lens on an Earth observation camera controlled by students on Earth.

Japanese Experiment Module (JEM) Inter-orbit Communication System (ICS)-Exposed Facility (EF) Jettison:
At 12:50 CT today, robotics ground controllers commanded an SSRMS disposal jettison of the retired JEM ICS-EF, a sub-component of the JEM ICS communications system. The Kibo Inter-Orbit Communication System (ICS) provided an independent intercommunications network between the Kibo module and Tsukuba Space Center (TKSC) of the Japan Aerospace Exploration Agency (JAXA). The ICS-EF was launched on the STS-127 mission (2J/A) in July of 2009, and was attached to the Exposed Facility Unit (EFU)-7 wh ere it was in service until August of 2017. Kibo science data is now delivered via the ISS Ku-band system which utilizes the expanded coverage of the Tracking and Data Relay Satellite System (TDRSS) network.

JEM ICS-EF - подсистема EF межорбитальной системы связи японского экспериментального модуля была отсоединена и отброшена от МКС:
Сегодня в 18:50 UTC наземные операторы робототехнического комплекса SSRMS выдали команду на отсоединение и сброс отработавший положенные сроки компонент JEM ICS-EF, подкомпонент коммуникационной системы JEM ICS. Межорбитальная коммуникационная система (ICS) модуля Кибо обеспечивала независимую связь между модулем и космическим центром Цукуба (TKSC) Японского агентства аэрокосмических исследований (JAXA). ICS-EF был запущен в рамках миссии STS-127 (2J/A) в июле 2009 года и присоединен к платформе EFU-7, где проработал до августа 2017 года. Теперь научные данные Кибо передаются через систему связи МКС в Ku-диапазоне с использованием сетевой спутниковой системы слежения и ретрансляции данных (TDRSS).

МОСКВА, 27 фев - РИА Новости. Первый корабль с экипажем Международной космической станции (МКС) стартует на ракете-носителе "Союз-2.1а" с полностью российскими комплектующими днём 9 апреля, сообщило НАСА.

Ранее сообщалось, что "Союз МС-16" станет первым кораблём с экипажем, который полетит на ракете "Союз-2.1а", полностью состоящей из российских комплектующих, вместо ранее эксплуатировавшейся ракеты "Союз-ФГ" с украинской системой управления. В августе 2019 года уже был осуществлён испытательный запуск корабля "Союз МС-14" без экипажа на ракете "Союз-2.1а".

На сайте НАСА говорится, что старт "Союза МС-16" с космодрома Байконур планируется 9 апреля в 11.04 мск, его стыковка с МКС - в тот же день в 17.20 мск.

В январе в Роскосмосе говорили РИА Новости, что "Союз МС-16" полетит к МКС по быстрой шестичасовой схеме, а не сверхбыстрой трёхчасовой, прошедшей отработку при полетах трёх грузовых кораблей "Прогресс" в 2018-2019 годах.

В экипаж "Союза МС-16" входят россияне Анатолий Иванишин и Иван Вагнер, а также американец Кристофер Кэссиди. Сейчас на МКС летают россиянин Олег Скрипочка и американцы Эндрю Морган и Джессика Меир.

NASA astronaut Andrew Morgan conducts research operations inside the Life Sciences Glovebox for the OsteoOmics-02 bone experiment.

The Expedition 62 crew is running a host of human research and space biology studies today aboard the International Space Station. The orbiting lab is also ramping up for new science being delivered on an upcoming U.S. cargo mission.

A crewmember's bones and flow of body fluids are affected by the weightless environment of space. Besides daily exercise and diet, scientists are exploring ways to offset the detrimental effects and ensure long-term mission health and success. Insights fr om the ongoing experiments may also prove beneficial to humans on Earth.

NASA Flight Engineer Jessica Meir worked on the OsteoOmics-02 bone research hardware that has been in operation all week and serviced science freezers wh ere biological samples are stowed. She also installed a carbon dioxide controller on an incubator that houses a variety of lifeforms such as microbes, animal cells and tissue cultures.

A common condition caused by living in space is called "puffy face." A crewmember's face becomes redder and rounder due to body fluids rising up as a symptom of weightlessness. NASA astronaut Andrew Morgan set up gear that measures the head pressure caused by this upward flow that has also been known to affect vision.

The SpaceX Dragon cargo craft is due to blast off toward the station on March 6 at 11:49 p.m. EST. It will arrive March 9 carrying about 5,600 pounds of cargo including live mice. Morgan installed hardware today that will house the rodents for the Mouse Habitat Unit-5 investigation from JAXA (Japan Aerospace Exploration Agency). He prepared the habitat specifically designed for the study and will attach it later to the upgraded Cell Biology Experiment Facility.

Commander Oleg Skripochka continued studying the physics of dust particles creating plasma crystals. The veteran cosmonaut also worked on orbital plumbing tasks before wrapping up a session that recorded his heart rate and blood pressure for 24 hours.

It was noticed that one of the 75-watt heater elements of the ESP-1 Secondary Heater string was no longer drawing power. The heater that failed is a redundant heater for either the spare Direct Current Switching Unit (DCSU) or spare Pump Flow Control Subassembly (PFCS) currently stowed on ESP-1. There are 2 secondary and 2 primary heater elements for both the DCSU and PFCS. Due to limited insight, and the fact that the heater elements are identical in size (75-watts), it is not possible to identify the specific heater patch that failed.

Posted Feb 28, 2020 at 1:25 pm


The Expedition 62 mission patch floats inside the seven-window cupola, the International Space Station's "window to the world." The orbiting complex was flying 265 miles above Russia near the Caspian Sea at the time this photograph was taken.

The Expedition 62 crew wrapped up the workweek with more bone studies and human research activities. Meanwhile, a U.S. cargo craft is one week away from launching to resupply the International Space Station.

NASA astronauts Jessica Meir and Andrew Morgan split their day between a pair of investigations exploring how the human physiology is impacted by long-term weightlessness.

The pair started Friday with ultrasound scans of the upper chest area followed by eye and head pressure checks. The biomedical exams are part of the Fluid Shifts study that seeks to understand and control the upward flow of body fluids in microgravity that affects astronauts. Results could inform preventative measures that keep crews healthy on future missions to the Moon, Mars and beyond.

Morgan then set up a 3D video camera in the afternoon to film Meir as she serviced bone cell samples for the OsteoOmics-02 experiment. The study is observing these cells for accelerated bone loss caused by microgravity. Doctors are pursuing the new knowledge to gain therapeutic insights into ground-based ailments such as osteoporosis. The virtual reality film is being recorded to provide cinematic, immersive experiences for audiences back on Earth.

Space physics continued in the Russian segment of the space station as Commander Oleg Skripochka studied the formation of plasma crystals. The experiment provides fundamental knowledge about the physics of microgravity potentially influencing advanced research activities and future spacecraft designs.

Meanwhile, processing continues at the Kennedy Space Center as SpaceX readies its Dragon resupply ship to launch atop the Falcon 9 rocket on March 6 at 11:49 p.m. EST. Dragon will arrive March 9 at the station packed with new science gear to study a wide variety of space phenomena. The experiments will be looking at how to grow food in space, develop nano-materials and increase fuel efficiency.
