NASA Space Station On-Orbit Status 21 July 2017 - Human Health and Performance Studies

The crew of Expedition 52 wrapped up an intensive week of research on Friday, concentrating on studies in the field of human health and performance.

On Thursday, the crew conducted their second ultrasound for the Sprint investigation, which studies the use of high-intensity, low-volume exercise training to minimize the loss of muscle, bone and cardiovascular fitness during long-duration space excursions. Using meticulous thigh and calf scans through remote guidance from the ground team, these results will help determine what changes astronauts are experiencing in microgravity and how best to manage those fluctuations for future missions.

Flight Engineers Peggy Whitson and Jack Fischer today will gather and transfer Fluid Shifts hardware to the station's Russian segment in preparation for Fluid Shifts Chibis (Lower Body Negative Pressure) operations that begin on Monday. Fluid Shifts investigates the causes for lasting physical changes to astronaut's eyes--a side effect of human space exploration in a microgravity environment. It's theorized that the headward fluid shift in space-faring explorers contributes to these changes. In response, a lower body negative pressure device is being evaluated to see if it can perhaps reverse this fluid shift. As an added bonus, what investigators glean from this study may contribute to the development of countermeasures against lasting changes in vision and prevention of eye damage.

The Expedition 52-53 crew that will lift off to the International Space Station within a week is finalizing preparations at the Baikonur Cosmodrome in Kazakhstan. Cosmonaut Sergey Ryazanskiy, along with astronauts Randy Bresnik and Paolo Nespoli, are slated to launch July 28 at 11:41 a.m. EDT for a six-hour journey to the orbiting laboratory. NASA TV will cover all the activities, so tune in.

On-Orbit Status Report

Exposed Experiment Handrail Attachment Mechanism (ExHAM) #1-2: The crew opened the Japanese Experiment Module Airlock (JEMAL) inner hatch and extended the Airlock slide table into the JEM. They detached and stowed samples for return to the Ground from the Handhold Experiment Platform #1 (HXP1) and attached new samples on the HXP1 for return to the JEM External Facility. Two of the original samples were left on the HXP1 for continued exposure. The ExHAM is a cuboid mechanism equipped with a fixture on the upper surface for grappling by the JEM Remote Manipulator System (JEMRMS) Small Fine Arm (SFA) and components on the under surface for attaching the ExHAM to the handrail on the JEM Exposed Facility.

Fluid Shifts: The crew gathered and transferred Fluid Shifts hardware to the ISS Russian segment in preparation for Fluid Shifts Chibis (Lower Body Negative Pressure) operations that begin on Monday. 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 lower body negative pressure device is being evaluated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and to prevention of eye damage.

Node 2 (N2) Bacteria Filter Remove & Replace (R&R): The crew R&Rd four expended bacteria filters in N2 that have reached end of life. They also clean the smoke detectors.

Compound Specific Analyzer-Combustion Products (CSA-CP) Maintenance: The crew installed new battery packs into the newly re-supplied CSA-CPs, reset the internal clock and data logger for each monitor and allowed all units to off-gas in an open environment.
