New data about the detrimental effects of zero gravity on the skeleton could have clinical implications for osteoporosis and other rheumatic conditions.
PARIS Astronauts lose decades’ worth of bone mass in space that many do not recover even after a year back on Earth, researchers recently said, warning that it could be a “big concern” for future missions to Mars.Previous research has shown astronauts lose between one to two per cent of bone density for every month spent in space, as the lack of gravity takes the pressure
Humans lose bone as they age, sustain injuries, or in any situation where their bodies are immobile. Very little is known about what actually occurs to astronauts or how they recover.

This loss happens because bones that would normally be weight-bearing on Earth, like your legs, don t have to carry weight in microgravity - you just float, said the team from University of Calgary in Canada.
