"Discovery was the return-to-flight orbiter after the loss of Challenger and then again after the loss of Columbia. To me, this gives it a certain feeling of bravery and hope. 'Don't worry,' Discovery seemed to tell us by gamely rolling her snow-white self out to the launchpad. 'Don't worry, we can still dream of space. We can still leave the earth.' And then she did." -- Margaret Lazarus Dean, Leaving Orbit: Notes from the Last Days of American Spaceflight
