It's time to open the space frontier to citizen explorers.

I think both the space shuttle program and the International Space Station program have not really lived up to their expectations.

I'm sure that there are places in the deserts in Australia that could be similar to where we might want to go on Mars.

A family needs to work as a team, supporting each other's individual aims and aspirations.

We feel that this stands as a symbol of the insatiable curiosity of all mankind to explore the unknown.

What are you going to do with astronauts who first reach the surface of Mars and then turn around and rocket back home-ward? What are they going to do, write their memoirs? Would they go again? Having them repeat the voyage, in my view, is dim-witted. Why don't they stay there on Mars?

The much-hyped Ares 1-X was much ado about nothing.
