SpaceX is talking about going to Mars by 2024, if things go well… 8 years from now. You will supposedly be able to buy a one-way ticket for US$550,000… and what’s the return trip going to cost?
The reusable booster is a nice touch. There are lots of plans in the works for going to the moon and Mars to build colonies and a few suggesting Venus is a better choice.
I think a more interesting idea for getting to space is the Space Elevator.
A Japanese company is talking about having an elevator working by 2050.
