>>11384813>thermal on re-entry
If Bezos wants to launch to space, he will need a reusable rocket. Any reusable rocket must survive atmospheric reentry heat. Its not an impossible thing, heck, its a very possible thing given SpaceX already does it regularly. In fact, its a problem for Bezo as as he hasn't demonstrated an orbital vehicle yet after 20 years. >fuel
There's no fuel in space, but there's virtually an infinite fuel on Mars for refueling.>habitable
Mars is the closest body that can be made habitable on dome by dome basis or through underground structure. You can drill underground about 15 meters/50 feet down and you'll get temperature and earth level atmospheric pressure. No such thing can happen in space. >Thermal management
Space is even worse for thermal management. As well as life support, radiation shielding, etc.
Your argument is stupid. All the problems you listed are 10x worse in space. At least on a surface like Mars, you can have underground shelter, or you can build dome structures, or buildings, etc. The materials are all on the surface within your reach. No such thing is in space. In space, you'd need to haul in multiple asteroids for various types of elements. If you're hauling in asteroids in space, then you might as well haul it in Mars orbit for mining or have it crash land for terraforming/etc.
