Astronauts do not have it straightforward once they come house, and it isn’t simply due to the change in gravity: their purple blood cell manufacturing drops whereas they’re in area, leaving them weakened on Earth.

The analysis is testing pink and white blood cell features, in addition to bone marrow fats ranges, to see how they modify earlier than, throughout and after spaceflight.
