We need the next generation to be motivated and to push technological boundaries, to seek out new innovations.

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

A hybrid human-robot mission to investigate an asteroid affords a realistic opportunity to demonstrate new technological capabilities for future deep-space travel and to test spacecraft for long-duration spaceflight.

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

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

By venturing into space, we improve life for everyone here on Earth - scientific advances and innovations that come from this kind of research create products we use in our daily lives.
