What's your idea for a cheap way to get people into space?

Actually, thanks to clever use of spectral imaging, we do have a pretty good idea of the composition of other worlds.
Ganymede and Europa are rich in water - in fact they are water worlds - and Mars and Titan have enough oxygen to meet human needs, provided it is refined with nuclear, solar or even wind power.
