One of the most hotly debated topics related to sending humans to Mars is the health effects of prolonged exposure to microgravity and how these might be mitigated.
Prolonged exposure to microgravity (a.k.a. “zero gravity”) has several serious effects on the human body:
- Without the need to support the weight of the body, the musculoskeletal system atrophies and weakens. Bone and muscle mass tend to decrease at a significant rate. Bone mass can decrease at 1-1.5% per month.
- Under normal gravitational forces…
