We may even be able to terraform Venus within 500 years, a much tougher nut to crack than Mars.

There is already an effort to colonize Venus. It's pretty clever actually. Apparently ordinary air will "float" in Venus Atmosphere, so large metal tanks filled with Air will float, and can be used to build heavy structures upon.

So Venus may have several Goodyear blimps.
