Rodent Research-12 (RR-12):

Спойлер

The crew restocked Rodent Habitats 3 and 4 and completed Mass Measurement Injection activities. The crew also replaced food bars in Habitats 1 and 2. Rodent Research-12, Tetanus Antibody Response by B cells in Space (TARBIS), examines the effects of spaceflight on the function of antibody production and immune memory. Spaceflight has a dramatic influence on immune response, but there is little research on its effect following an actual challenge to the body's immune system. Using a mouse model makes this possible, as the mouse immune system closely parallels that of humans.

This morning, just two days following its nighttime launch from the Florida coast, SpaceX's Dragon cargo spacecraft was captured and installed on the Earth-facing side of the International Space Station's Harmony module at 9:32 a.m. EDT.

Expedition 59 astronauts David Saint-Jacques of the Canadian Space Agency and Nick Hague of NASA successfully employed the space station's robotic arm to grapple Dragon at 7:01 a.m., which brings the number of spaceships docked at the space station to six. Other vehicles visiting include Russia's Progress 71 and 72 resupply ships and the Soyuz MS-11 and MS-12 crew ships, as well as Northrop Grumman's Cygnus space freighter.

Dragon's arrival heralds a busy week for the crew. Today, NASA astronauts Anne McClain and Christina Koch unpacked and activated time-critical experiments after completing checkout of the spacecraft. Fresh biological samples, such as kidney cells, were stowed in science freezers and incubators for later analysis. New lab mice were also quickly transferred and housed in specialized habitats to enhance research for an immune system study that aims to keep astronauts healthy for long-duration missions in space, which will become even more commonplace as our destinations extend to the Moon and beyond.

SpaceX's 17th cargo flight to the space station under NASA's Commercial Resupply Services contract supports dozens of new and existing investigations. NASA's research and development work aboard the space station contributes to the agency's deep space exploration plans, including returning astronauts to the Moon's surface in five years.

This latest commercial cargo delivery refreshed the orbiting laboratory with 5,500 pounds of research, crew supplies and hardware.

New Science Being Unpacked and Worked Aboard Orbital Lab

Mark Garcia
Posted May 7, 2019 at 2:25 pm


The SpaceX Dragon cargo craft is installed to the Harmony module's Earth-facing port a few hours after it was captured by astronauts David Saint-Jacques and Nick Hague with the Canadarm2 robotic arm on May 6, 2019.

Six spaceships are now parked at the International Space Station and the Expedition 59 crew is working on the newest science delivered Monday. Astronauts will continue to live and work in space longer and scientists want to know how humans and a variety of other organisms adapt to support these missions.

NASA astronaut Anne McClain tended to several dozen mice delivered to the orbital lab Monday on the SpaceX Dragon cargo craft. The rodents' immune systems are similar to humans and scientists are monitoring them to detect any changes caused microgravity.

NASA astronaut Christina Koch set up the Microgravity Science Glovebox today to begin operations with the new Micro-14 pathogen study. Microgravity can increase the virulence of pathogens and doctors are seeking to understand the process to keep space crews safe and healthy.

Koch and McClain both started Tuesday unpacking frozen biological samples from Dragon. The duo stowed the samples into different science freezers aboard the station for later analysis and experimental work.

McClain, Commander Oleg Kononenko and Flight Engineer Nick Hague also explored head and eye pressure caused by upward fluid shifts due to the effects of microgravity. The long-running human research experiment seeks to reverse the upward flow and alleviate the symptoms reported by astronauts.

Posted May 8, 2019 at 3:35 pm


Expedition 59 Flight Engineers (from left) Anne McClain, David Saint-Jacques and Christina Koch are gathered inside the U.S. Destiny laboratory.

The International Space Station has all but one of its seven ports occupied by two crew ships and four cargo ships today. With plenty of food, fuel and supplies, the Expedition 59 crew is busy conducting new science experiments delivered to the orbital lab.

The crew researched an array of space biology today including pathogen virulence, immune system changes and upper body pressure that can affect mission success. Human research and life science is key in microgravity as NASA learns to support healthy astronauts for longer missions farther into space.

NASA Flight Engineer Christina Koch continued studying why pathogens increase in virulence due to the weightless environment of space. She performed inoculation procedures on cell cultures to help scientists understand critical cellular and molecular changes that occur on the absence of gravity.

Koch then joined fellow astronauts Anne McClain and David Saint-Jacques in the afternoon exploring how the immune system responds during a long-term space mission. The crew is observing dozens of mice on the orbital lab to characterize the response changes since the mouse immune system closely parallels that of humans.

McClain also participated on more Fluid Shifts research with Flight Engineers Alexey Ovchinin and Flight Engineer Nick Hague. The trio worked with a variety of biomedical hardware today observing the impacts of increased head and eye pressure caused by microgravity. The long-running human research experiment seeks to reverse the upward flow and alleviate the symptoms reported by astronauts.

В NASA считают, что исследования на МКС помогают подготовиться к полетам на Луну и на Марс

Замдиректора NASA по пилотируемым программам Билл Герстенмайер отметил, что агентство сейчас работает над созданием скафандра, пригодного как для выходов в космос с МКС, так и для лунных экспедиций

ВАШИНГТОН, 9 мая. /ТАСС/. Исследования на Международной космической станции (МКС) позволяют отработать новые технологии, необходимые для полетов к Луне и Марсу, и поэтому эксплуатировать МКС следует до тех пор, пока это технически возможно. Такое мнение высказал в среду на слушаниях в комитете Палаты представителей по науке, космосу и технологиям Конгресса США заместитель директора NASA по пилотируемым программам Билл Герстенмайер.

"Мы должны использовать те возможности, которые имеются на МКС, являющейся хорошим испытательным полигоном, - отметил он. - Мы должны продолжать использовать МКС до тех пор, пока это возможно с технической точки зрения. Члены экипажей находятся на ней по году, и это дает нам исключительно ценные знания, необходимые для того, чтобы оценивать последствия для здоровья членов будущей марсианской экспедиции".

"Эксплуатация МКС действительно приносит пользу, и если бы исследований на МКС не было, то это негативно повлияло бы на наши планы полетов к Луне и замедлило бы подготовку полета на Марс, - подчеркнул Герстенмайер. - МКС нам нужна".

По его словам, NASA сейчас работает над созданием космического скафандра, пригодного как для выходов в космос с МКС, так и для лунных экспедиций. "Мы работаем над конструкцией нового скафандра для МКС, - отметил он. - В этом скафандре будут использованы технологии подачи кислорода, контроля над влажностью и температурой, пригодные и для скафандра, которым в будущем воспользуются астронавты на поверхности Луны. Над созданием скафандра работают эксперты в Центре космических полетов имени Джонсона в Хьюстоне (штат Техас)".
