The foreseeable future for man in space is the moon, not Mars. The moon is close - orders of magnitude easier to get there and back again. Its gravity well isn't a prison. You can probably launch stuff from there to earth with a linear accelerator. It's full of natural resources that can be used to build colonies and space ships. There's no environment to degrade. Mars doesn't make any sense. The moon does. And besid…
There are advantages and disadvantages. Closeness is a big issue, I'll grant you that. Robots on the Moon's surface can get quick guidance form humans on Earth much more quickly than robots on Mars. And if something goes wrong you can get home more quickly. The gravity well difference is a thing but isn't straightforward. You need twice as much delta-v to take off from Mars as from the Moon (3800 m/s versus 1730 m/s)…

#71There's no solar night at the poles, and tall structures are easy to build in low gravity.
