I'm convinced that sending people to Mars is so expensive that if you go once and bring the people back and then go again and bring the people back, we're eventually going to run out of money. But what if we send people the first time and they don't come back? What if they stay there?Buzz Aldrin
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.Buzz Aldrin
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.Buzz Aldrin
I'm in favor of changing the destination of humans. There are a lot of manned missions that can be done, but not in the direction of the moon.Buzz Aldrin
Space architectures capable of supporting a permanent human presence on Mars are extraordinarily complex, with many different interdependent systems.Buzz Aldrin
In Mars, we've been given a wonderful set of moons... where we can send continuous numbers of people.Buzz Aldrin
