NASA Commentator Lori Meggs at the Marshall Space Flight Center talks with Mike Stenger, one of the co-principal investigators of the Fluid Shifts experiment, which is measuring how much fluid shifts to an astronaut’s upper body during the time he or she is in weightlessness on board the International Space Station.
Researchers have hypothesized that the fluid shift leads to increased pressure within the skull and to the back of the eye, and may be responsible for vision changes that many astronauts experience after a long-duration mission. Stenger uses Lori as a guinea pig to demonstrate how he’s gathering data from the station crew members for this investigation.
