The Assessment of Bone Turn-over and Bone Morphology
Bone Health

Exposure to microgravity and immobilization can cause a loss of bone density, which can increase the risk of bone breakage and injury. In microgravity, the changes start to take place very soon after leaving Earth—the extent and timeframe of reversal of these changes upon return from space are under investigation. This ongoing ESA-led project is monitoring whether bone loss halts or continues upon re-entry after human spaceflight missions.
