Summary
This study tested whether a special camera can see tiny blood vessels (microcirculation) in healthy volunteers during brief periods of weightlessness on a parabolic flight. The goal is to better understand how the heart and blood vessels adapt to space, which could help prevent fainting or heart issues in astronauts. Sixteen healthy adults took part in this ground-based feasibility test.
