Crew Unpacks Dragon and Activates New Science

Mark Garcia
Posted Dec 8, 2020 at 1:07 pm


The upgraded SpaceX Cargo Dragon vehicle approaches the space station as both vehicles were orbiting above the Pacific Ocean off the coast of Mexico.

Six spaceships, three U.S. and three Russian, are parked at the International Space Station after Monday's arrival of the upgraded SpaceX Cargo Dragon vehicle. The Expedition 64 crew will spend the rest of December focusing on science as 2021 shapes up to be a busy year on the orbital lab.

Two Dragon spaceships, one cargo craft and one crew ship, are docked to the station's Harmony module for the first time ever. The Cargo Dragon docked Monday afternoon to Harmony's space-facing port where it will stay for one month. The Crew Dragon has been docked to Harmony's forward port since Nov. 16 and will return four astronauts back to Earth in the spring.

Cargo Dragon's hatch was opened shortly after its automated docking and the crew soon began unpacking and activating the first of 2,100 pounds of new science investigations. The U.S. resupply ship's main payload, the NanoRacks Bishop science airlock, will be installed with the Canadarm2 robotic arm to the Tranquility module later this month.

NASA Flight Engineers Shannon Walker and Michael Hopkins began Tuesday offloading the Dragon-transported critical research samples and stowing them in science freezers to be examined later. Their crewmates Kate Rubins installed new science freezers in the station, while Victor Glover set up newly delivered habitats carrying rodents for analysis.

A new human stem cell experiment, Space Organogenesis, got underway today after JAXA astronaut Soichi Noguchi collected biological samples and research hardware from Dragon. Microgravity will give scientists insight into growing organs and observing genetic changes which could impact regenerative medicine.

In the Russian segment of the station, Commander Sergey Ryzhikov explored advanced space photography techniques before working on cargo operations with the docked Progress 76 resupply ship. His fellow cosmonaut, Flight Engineer Sergey Kud-Sverchkov, worked on Earth observation hardware then serviced repair tools.

Система получения кислорода "Электрон-ВМ" вновь отключилась на МКС
12.12.2020 14:53:50
       Москва. 12 декабря. ИНТЕРФАКС - Система получения кислорода "Электрон-ВМ" на Международной космической станции (МКС) в очередной раз вышла из строя из-за проблем с давлением, сообщил экипаж станции во время переговоров с Землей.
      "Электрон" отключился не из-за проблем с питанием, а из-за проблем с давлением кислорода", - сказал космонавт Сергей Рыжиков в ходе переговоров с ЦУПом, трансляцию которого ведет NASA.
       По его словам, сбой произошел около 11:50.
       За последние два месяца система получения кислорода на МКС выходила из строя, как минимум, пять раз. Сообщалось о сбоях в работе "Электрона" 14, 17, 19 и 21 октября, а также 10 декабря. В "Роскосмосе" заявили, что ситуация не угрожала жизни и здоровью экипажа.
       Система "Электрон" располагается на российском сегменте МКС в модуле "Звезда". Во время ремонта системы работает дублирующая система в американском сегменте станции.

Спойлер

       С августа 2020 года экипаж МКС занимается поиском и устранением утечки воздуха в российском модуле "Звезда". Высказывается мнение, что разгерметизация может быть связана с возрастом станции. Такой точки зрения придерживается, в частности, космонавт Иван Вагнер, вернувшийся со станции в октябре.
       Со своей стороны исполнительный директор "Роскосмоса" Сергей Крикалев отверг утверждения об увеличении числа поломок на станции и заявил, что модули МКС способны проработать существенно дольше своего гарантийного срока.
       Замглавы ракетно-космической корпорации "Энергия" Владимир Соловьев ранее сообщил, что в корпорации прогнозируют "лавинообразный выход из строя многочисленных элементов на борту МКС" после 2025 года.
       Ранее глава "Роскосмоса" Дмитрий Рогозин заявил, что Россия готовится к созданию новой орбитальной станции.

       За последние два месяца система получения кислорода на МКС выходила из строя, как минимум, пять раз. Сообщалось о сбоях в работе "Электрона" 14, 17, 19 и 21 октября, а также 10 декабря. В "Роскосмосе" заявили, что ситуация не угрожала жизни и здоровью экипажа.
       Система "Электрон" располагается на российском сегменте МКС в модуле "Звезда". Во время ремонта системы работает дублирующая система в американском сегменте станции.
       С августа 2020 года экипаж МКС занимается поиском и устранением утечки воздуха в российском модуле "Звезда". Высказывается мнение, что разгерметизация может быть связана с возрастом станции. Такой точки зрения придерживается, в частности, космонавт Иван Вагнер, вернувшийся со станции в октябре.
       Со своей стороны исполнительный директор "Роскосмоса" Сергей Крикалев отверг утверждения об увеличении числа поломок на станции и заявил, что модули МКС способны проработать существенно дольше своего гарантийного срока.
       Замглавы ракетно-космической корпорации "Энергия" Владимир Соловьев ранее сообщил, что в корпорации прогнозируют "лавинообразный выход из строя многочисленных элементов на борту МКС" после 2025 года.
       Ранее глава "Роскосмоса" Дмитрий Рогозин заявил, что Россия готовится к созданию новой орбитальной станции.

На МКС отказала российская система получения кислорода
16:23 12.12.2020 (обновлено: 18:11 12.12.2020)
...
Согласно переговорам, в субботу днем космонавт Сергей Рыжиков сообщил в подмосковный Центр управления полетами об аварийном выключении "Электрона". Он добавил, что отказ произошел из-за низкого давления в системе и по времени совпал с отключением пылесоса, используемого для уборки на российском сегменте МКС. Многократные попытки включить "Электрон" не привели к успеху, специалисты на Земле разбираются с проблемой.

МОСКВА, 12 декабря. /ТАСС/. Система подачи кислорода "Электрон-ВМ" на Международной космической станции отказала после выключения пылесоса. Об этом доложил космонавт Сергей Рыжиков во время переговоров с Центром управления полетами (ЦУП), трансляция которых ведется на сайте NASA.

"Отказ прошел в 08:58 (11:59 мск)", - отметил Рыжиков, уточнив, что это произошло после отключения пылесоса.

Специалист ЦУП назвал отключение аварийным и пояснил, что систему нужно отключить грамотно.

Ранее космонавты проводили тестовые включения пылесоса. Бортовой компьютер выдал несколько ошибок. Затем они выключили пылесос, чтобы "выполнить уборку руками".

Система подачи кислорода выходила из строя в октябре. В конце месяца экипаж станции под руководством главной оперативной группы управления разобрал систему и изучал ее на предмет неисправностей. На время ремонтных работ задача по подаче воздуха была переброшена на дублирующую систему, находящуюся на американском сегменте.

В четверг в пресс-службе Роскосмоса сообщили ТАСС, что работа системы "Электрон-ВМ" восстановлена.

О системе
"Электрон-ВМ" предназначена для подачи кислорода экипажу МКС. Его разработчиком является НИИхиммаш. Система способна вырабатывать от 25 до 160 литров кислорода в час и дополнительно от 50 до 320 литров водорода в час. Принцип действия основан на электролизе воды с щелочным электролитом в проточном электролизере, после чего происходит разделение газожидкостной смеси. На станции имеются запасы кислорода, также в американском модуле "Транквилити" есть своя система генерации кислорода.

Ложка, вилка, нож? Нет... Ножницы!

У каждого космонавта есть свой набор СПП. Мы их даже подписываем, чтобы не перепутать. Эта непонятная на первый взгляд аббревиатура расшифровывается не иначе, как «средства приема пищи», т.е, по-земному, это столовые приборы.
