NASA Space Station On-Orbit Status 24 July 2018 - Life Science Research Continues.

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.

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.

On-Orbit Status Report

Rodent Research-7 (RR-7): The crew completed the first of two days of rodent operations for the RR-7 investigation today. Crewmembers performed bone densitometer scans, blood draws, fecal pellet collections, and sampling operations. RR-7 examines how the space environment affects the community of microorganisms in the gastrointestinal tract of mice (also known as the microbiota). It also looks at microgravity's effects on multiple physiological systems known to be affected by the microbiota, including the gastrointestinal, immune, metabolic, circadian, and sleep systems. These studies should help explain mechanisms underlying interactions between these systems and the role of the microbiota in these interactions.

Exposed Experiment Handrail Attachment Mechanism (ExHAM) #1: Tonight robotic specialists in Tsukuba will use the Japanese Experiment Module Remote Manipulator System (JEMRMS) with the Small Fine Arm (SFA) to transfer the Handhold Experiment Platform (HXP) from the JEM Airlock Slide Table to the JEM Exposed Facility handrail.

Treadmill 2 (T2) Status: This morning, the crew replaced the T2 Station Support Computer (SSC) and the ground team configured it for T2 use. The subsequent rack activation was nominal and T2 is now operational and 'Go' for the crew's use.

Dragon Cargo Ops: Today the crew completed approximately four hours of cargo operations as they continued to pack and load items slated for return on the SpaceX-15 Dragon vehicle. Only a few steps remain in the current Cargo Message and specialists hope to upload the next message tomorrow. An estimated fifteen hours of activities remain to finish loading the vehicle prior to the planned departure date of 3 August.
