Distance Earth to ISS: 250 miles.
Distance Earth to mars: about 140 million miles
It's like camping in your own back yard vs. camping 2000 miles away from home. But sure, otherwise it's basically the same.
- lukan 3y agoYes it is. You "just" need more backup systems as indeed, you cannot just come inside to get what you forgot, or replace what just broke or go sleep inside, if it turns out too cold outside. That is for sure and that is why I would start with the moon. To test more all of the equipment. And then test a little more. And then do some more testing.
- gregoriol 3y agoLanding is also way harder than docking in orbit
- lukan 3y agoBut once you landed, gravity is something nice.
- SideburnsOfDoom 3y agoMars gravity is about 38% of Earth gravity. Just how "nice" this is to human health in the long term, is still unknown. And if your health isn't coping with it, the quickest way back to Earth likely involves 6 months of zero-g.
- lukan 3y agoSure - but this was about the difficulties of a habitat on mars vs habitat in space. And for some reason, there were many, one can allmost say fanatics, who volunteered for the scam called Mars One, taking a one way ticket with the knowledge that they would die, if something goes wrong.
