I feel privileged and honored to have flown. It's been a tremendous ride, looking back on the legacy and accomplishments, like the Hubble telescope and the launching of the International Space Station in 1998.

Science sent the Hubble telescope out into space, so it could capture light and the absence thereof, from the very beginning of time. And the telescope really did that. So now we know that there was once absolutely nothing, such a perfect nothing that there wasn't even nothing or once.

That's what Hubble can do for us. It can tell us whether the universe is expanding forever or if one day it's going to come back together.

It's always a combination of physics and poetry that I find inspiring. It's hard to wrap your head around things like the Hubble scope.

There is no stronger case for the motivational power of real science than the discoveries that come from the Hubble Space Telescope as it unravels the mysteries of the universe.

With correction, and given the chance, 'Terra Nova' can and will deliver seasons of transcendent images and story-telling. Failing to renew 'Terra Nova' is shortsighted, as myopic as it would have been to scrap the Hubble. 'Terra Nova' is the Hubble Telescope of television.
