[Paul Ross]

Agreed, heroes all, who ride the barely-contained explosions to orbit...and God-willing, back again. The only fitting tribute to the heroes of STS-107, Space Shuttle Columbia, is to resume manned space flight. And not just Shuttle operations... but to fulfill the larger mission of exploration and development.

[Old Professer]

What, exactly, is the larger mission?

When I used to farm, I always dropped a few extra kernals in the hill, is that it?
