Does he worry that the low gravity of Mars may not be sufficient to sustain life? We know we can survive in zero g for a few years but the damage to the body can include vision impairment, bone lose, etc... Does this maybe make Venus a better target?
- dreiser 10y agoWell it depends. If human will move to Mars, do they really need not to lose their bones strength and so? If people on Mars will keep 1/3 of what their body compared to Earth because there is about 1/3 gravity, they will be fine for Mars becausee they adapted. But they won't be able to come back. Venus gravity is just little lower than Earth's but that mean it is harder to land same amount of cargo there (compared to Mars) + you are definitely not coming back because of it anysoon.
- jmichelz 10y agoWhy would they not be able to come back? Just build their bodies back up. Or keep them in shape to begin with.
- taf2 10y ago10 days later I realize... interestingly we know what happens to the body when it's exposed to zero gravity and 1g of gravity... but we really don't know what happens at 20% or really anything between zero and one g...
