Thought there was research that they'd have to have some kind of artificial gravity as in the 2001 family of movies? If not brain fluids than bone mass.
Also, what's the weight in food that's required to keep somebody alive for 4 years? Will water be more of a problem than food? As per the Martian, they can pre-position food and supplies for the stay and the return, but it seems energy-expensive to chase down a capsule on the voyage to Mars to drop off supplies. Hell of a DoorDash, eh?
- turtleyacht 3y agoYep, artificial gravity. "Space health" could be its own industry. Varda for pharma recently [1], and even space manufacturing in the future.

- schwartzworld 3y agoCentrifugal force seems like a good solution for simulating gravity, but maybe I'm underestimating the difficulty of getting a spacecraft spinning sufficiently.
- jleyank 3y agoThis is what I thought as well. There might be issues with angular momentum and inertia, and problems with windows (gravity would be perpendicular to the axis of rotation) but they could finesse this by having the living/exercise/sleeping quarters artificially lit and the control environment with those velcro sox padding about on carpet.
