Mars is there, waiting to be reached.

The guys who walk on Mars are going to be historic.

It's great that people are interested in Mars.

I almost feel like Mars has been taking care of me for all of these years.

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

We've gotta become the Martians. I'm a Martian - I tell you to become Martians. And we've gotta go to Mars and civilize Mars and build a whole civilization on Mars and then move out, 300 years from now into the universe. And when we do that, we have a chance of living forever.

If there was an observer on Mars, they would probably be amazed that we have survived this long.

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

I hope I'm still alive to see an expedition set off for Mars.
