When you're in a spacecraft, you need to know what things you can touch and what things you shouldn't touch!

Exploring Mars is a far different venture from Apollo expeditions to the moon; it necessitates leaving our home planet on lengthy missions with a constrained return capability.

A space program that truly goes somewhere! With his deeds, not only words, President Obama has revitalized our struggling space program.

My sister called me "Buzzard" when I was a baby - she couldn't say "Brother" so I've been Buzz my whole life.

Not everyone can be an astronaut and go into space, some people with sufficient resources can purchase and fly sub-orbitally thanks to various companies and for more money (considerably) fly into orbit.

Mars could very well be a staging location for the resources of the asteroid belt. We have to learn how to get a payback somewhere, but it's beyond Mars that the real payoff will come from minerals.

It's not easy to get human beings into orbit. So far only three nations have been able to do that, with all the resources that they put together. And I'm just a little skeptical that that's going to be done by the private sector without making use of what has been done by the government.
