Land on Mars, a round-trip ticket - half a million dollars. It can be done.
I think there would be no shortage of applicants to the government astronaut corps to be settlers on the planet Mars. And I think this would be very inspiring.
We like to talk about pioneering Mars rather than just exploring Mars, because once we get to Mars, we will set up some sort of permanent presence.
Mars has a bit of air pressure; maybe we can build up that atmosphere to be a bit more accommodating to humans.
My sons and their wives landed on Mars to start another race.
Vegas is the city of temptation. I think, perhaps, it is an experiment by NASA. If we're going to send people to Mars, how will we create false economies and cultures to satisfy them? Vegas has the answer. People go there when they've nothing left to lose.
We need to begin thinking about building permanence on the Red Planet, not just have voyagers do some experiments, plant a flag and claim success. Having them go there, repeat this, in my view, is dim-witted. Why not stay there?
It might be helpful to realize, that very probably the parents of the first native born Martians are alive today.
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.
We're going to become the martians when we land there. When we explore and build communities, we become the martians. That's a wonderful destiny for all of us.
Going to Mars would make NASA great again.
Did the Pilgrims on the Mayflower sit around Plymouth Rock waiting for a return trip? They came here to settle. And that's what we should be doing on Mars. When you go to Mars, you need to have made the decision that you're there permanently. The more people we have there, the more it can become a sustaining environment. Except for very rare exceptions, the people who go to Mars shouldn't be coming back. Once you get on the surface, you're there.
I think humans will reach Mars, and I would like to see it happen in my lifetime.
The single best thing about Mars is the reduced gravity. It's 38 percent of Earth's gravity - about one third. Almost never have you seen that portrayed in film or television. Mars is just portrayed as a place that's got reddish sand but is otherwise pretty much identical to the Mojave Desert, and that's not the case.
If the Chinese are the first to the asteroids or the first to Mars, good for them, as far as I'm concerned.
Will we have a colony on Mars? I think so.
It's not a matter of if we're going to go to Mars, it's a matter of when.
In Mars, we've been given a wonderful set of moons... where we can send continuous numbers of people.
A permanent base on Mars would have a number of advantages beyond being a bonanza for planetary science and geology. If, as some evidence suggests, exotic micro-organisms have arisen independently of terrestrial life, studying them could revolutionise biology, medicine and biotechnology.
Every couple of years, we could dispatch people from Earth to Mars.
