I suggest that going to Mars means permanence on the planet - a mission by which we are building up a confidence level to become a two-planet species.

Mars is the only place in the solar system where it's possible for life to become multi-planetarian.

The purpose of going to Mars is for humans to first begin to occupy, permanently, another planet in the solar system. The astronauts or pilgrims, whatever you might call them, are going to be very historically unique human beings.

Mars has a bit of air pressure; maybe we can build up that atmosphere to be a bit more accommodating to humans.

I would suspect strongly that over a period of time, if we put our mind to going to Mars, it will be a consortium of several countries.

I think humans will reach Mars, and I would like to see it happen in my lifetime.

People will visit Mars, they will settle mars, and we should because it's cool.

We're not going to get humans to Mars until at least the mid-2030s, and the world is going to change by then.

I haven't a clue if there is life on other planets but I'd be charmed if we found a unicellular organism on Mars. It would change our whole concept of life on Earth.

We could have human intelligence in orbit around Mars, building things there.
