What is the gravitational field at ground level like on Mars? Would it not have adverse affects on human physiology over time? Like muscle atrophy, bone loss, circulatory weakening, etc.
Matt Damon said the gravity is, like, 2/3 what Earth’s gravity is.
Martian gravity is about 0.38 times earth gravity. That would affect muscle tone and bone density in the long term, but those effects would not matter so long as you stayed on Mars. The adjustment when returning to earth might be a big deal, but only if they returned, and the extended transit time in zero-g space would be a much bigger factor.
