NASA Space Station On-Orbit Status 25 July 2018 - Astronaut Medical Research.

Expedition 56 crewmembers collaborated for the second day in a row studying how living in microgravity impacts rodents.

The space research onboard the International Space Station is helping doctors keep astronauts healthy in space and while developing advanced therapies for humans on Earth. Rodent research, and a variety of other life science studies observing organisms in space, has been ongoing for years aboard the orbital laboratory. The latest experiment, Rodent Research-7, looks at how microbes affect the physiology of mice. The mice and research gear were delivered July 2 aboard the SpaceX Dragon. Scientists are seeking to understand how microbes affect the gastrointestinal, immune, metabolic, circadian, and sleep systems.

Astronauts Drew Feustel and Alexander Gerst collected blood samples and measured the bone mass of the rodents today. Flight Engineers Ricky Arnold and Serena Auñón-Chancellor contributed to the research work stowing biological samples in science freezers. The samples will be returned to Earth Aug. 3 when Dragon splashes down in the Pacific Ocean for retrieval and analysis by scientists on Earth.

On-Orbit Status Report

Rodent Research-7 (RR-7): Today the crew completed the second 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. Following these operations, the crew performed clean-up activities in the Microgravity Science Glovebox (MSG) to prepare the facility for upcoming science. 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 effect on multiple physiological systems known to be effected 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 Robotics Operations: Last night the robotic specialists in Tsukuba used the Japanese Experiment Module Remote Manipulator System (JEMRMS) with the Small Fine Arm (SFA) to remove the Handhold Experiment Platform (HXP) from the JEM Airlock Slide Table and install it on the JEM Exposed Facility handrail.
