Should We Go to Mars or Back to the Moon?

Real stupid that Congress chose to exclude China from the International Space Station.

Thinking NASA has already chosen Mars and China may have chosen the Moon.

- Gravity You said about gravity exposure. If you think about the duration of travel and surface presence, Mars and Venus definitely sucks - we will spend many months in space and only weeks on surface/in air. Yeah, we can solve this with rotating living rings... Moon in this regard is better - few days for travel and months on surface. In any case it is better than on ISS and cheaper than building rotating living rings; - Money return Moon can become a very profitable business! Mars and Venus... Any ideas? - Energy Venus and Moon definitely wins when it comes to the energy - tons of sunshine! Mars is not that good in this regard; - Rescue The winner is, of course, Moon. Few days and we save the guys. Mars and Venus - everything on their own, sorry guys! - Radiation All 3 objects are problematic, that is for sure! - Water Moon seems to have enough ice, Mars is keeping it underground most of the time. Venus... Can anybody enlighten me?
