James Cameron on Exploration
Now Exploration with a capital E is in the air again, in what will hopefully become some kind of renaissance. Eleven billion hits to NASA's Web site during the Spirit and Opportunity rovers' exploration of Mars is an astounding groundswell of support.

It is only now sinking in that one is exploration and the other is, well construction.
