Astronauts hook their feet under handles to stay in place while doing things on the I.S.S. They do this so extensively that they develop callus on top of their feet and loose it on their heels. Once back on Earth walking without hardened skin on the heels is said to be painful until they have re-developed it.
Here is an account of astronaut Scott Kelly: https://www.businessinsider.com/scott-kelly-weirdest-thing-year-in-space-2016-2 https://www.businessinsider.com/scott-kelly-weirdest-thing-y...
- kingsuper20 5y agoThat's interesting but doesn't sound like much of a prosthetic to add to the proposed legless astronaut corps(tm). Somebody must have studied this. Effect of G-forces on amputees, perhaps there's less in the way of nutrition and oxygen needs. For that matter, I wonder what tests have been done to find natural differences in resource depletion depending on the individual, that sounds like an obvious selection point for a Mars mission or any other long-term isolation.
