The biggest benefit of Apollo was the inspiration it gave to a growing generation to get into science and aerospace.

I want to reach a new generation. That's why I am Twittering now. I have a BlackBerry, an iPhone and a Mac.

I feel we need to remind the world about the Apollo missions and that we can still do impossible things.

There's no doubt who was a leader in space after the Apollo Program. Nobody came close to us. And our education system, in science, technology, engineering and math, was at the top of the world. It's no longer there. We're descending rather rapidly.

I think the people who experienced the Apollo missions came away from that experience wondering to themselves, 'When can we get a chance to experience spaceflight?' I've heard that many, many times: that people got into a new career field hoping that they would be able to experience spaceflight.

There's a historical milestone in the fact that our Apollo 11 landing on the moon took place a mere 66 years after the Wright Brothers' first flight.
