FLUID STUDIES IN SPACE BENEFIT ALL

As fluid shift research continues, Expedition 50 flight engineer Thomas Pesquet of ESA (European Space Agency) juggles a set of video cameras in the microgravity environment of the International Space Station.

Ongoing research in science and experimentation continues aboard the International Space Station. Today’s focus in on fluid shifts in micro-gravity environments.

The Expedition 50 crew members explored a variety of space phenomena today to help researchers improve life for humans and stimulate children’s curiosity in science, technology, engineering and mathematics.

Scientists are working to understand how fluids behave not just in spacecraft fuel tanks and containers but also inside an astronaut’s body. Micro-gravity creates a head-ward flow of fluids that increases pressure on the back of an astronaut’s eyes potentially causing damage and affecting vision.

NASA astronaut Peggy Whitson and her Soyuz crewmates Oleg Novitskiy and Sergey Ryzhikov explored the effectiveness of a suit that may reverse these upward fluid shifts. Whitson and Novitskiy used a combination of eye exams and ultrasound artery scans on Ryzhikov today while he wore the Lower Body Negative Pressure (LBNP) suit today. The LBNP may offset the microgravity-induced fluid shifts possibly reducing the risk of vision changes in space.

Commander Shane Kimbrough reached out to schoolchildren this morning reading a story book and videotaping a simple fluids experiment. The Story Time From Space series seeks to increase science literacy by engaging students and teachers.

STATION CREW GEARING UP FOR 2017

The Expedition 50 crew enjoys an international Christmas dinner aboard the space station while gearing up for space walks and science in 2017.

With 2017 just around the corner, the space station crew is gearing up for January space walks, maintenance, and science research.

The Expedition 50 crew aboard the International Space Station spent the week working on an array of science, maintenance and spacewalking preparation to close out 2016.

Kimbrough and Flight Engineers Peggy Whitson and Thomas Pesquet are getting ready for a pair of spacewalks on Jan. 6 and 13. The spacewalks, in conjunction with remote robotics work, will complete the replacement of old nickel-hydrogen batteries with new lithium-ion batteries on the station’s truss structure. The crew performed a loop scrub on their spacesuits, reviewed spacewalking procedures and did a fit verification with their suits on Friday.

The crew participated in a variety of science experiments during the week including the Fluid Shifts study, which investigates the causes for  lasting physical changes to astronauts’ eyes; performed the final harvest of the Outredgous Romaine Lettuce from the Veggie facility, which is further demonstrating the ability to grow fresh plants in space to supplement crew diets; and continued preparing the station’s Combustion Integrated Rack (CIR) for the upcoming Cool Flames Investigation, which will provide new insight into the phenomenon where some types of fuels initially burn very hot, then appear to go out — but they continue burning at a much lower temperature, with no visible flames (cool flames).

Going into New Year’s weekend, the crew will enjoy their typical off-duty time on Saturday and Sunday. They also will have Monday, Jan. 2 off.
