NASA is studying how astronauts’ bodies adapt to living and working in space as mission managers plan longer human missions to the Moon, Mars and beyond. The long-running Fluid Shifts investigation is observing the impact of pressure on the brain and eyes due to the upward flow of body fluids caused by weightlessness.
Flight Engineers Jessica Meir and Andrew Morgan spent Monday morning collecting their blood, saliva and urine samples for the biomedical study. They spun the samples in a centrifuge before stowing them in a science freezer for analysis on Earth.
The duo then split up as Meir serviced cell samples for a bone study, while Morgan checked on samples being observed for a bio-fuel experiment. They got back together at the end of the day for eye exams as part of the Ocular Health study.
Station Commander Oleg Skripochka, a veteran of two prior station missions, juggled a wide array of space research. He first studied heavily charged particles, or plasma crystals, before setting up Earth observation gear to be remotely controlled by students on the ground. Next, Skripochka split his time on a pair of Earth studies seeking ways to monitor conditions and forecast natural and man-made disasters.
