 Now, recognition is cool, but it's really not, I think, what scientists do this for. We get into this business, and engineers do too, because we like seeing the process and doing the process and discovering things. Engineers like seeing their work go up into the sky and help us discover new things, and we like working with each other. So, there's a satisfaction in doing everyday things, even though you're not all the way to the end. You know that you're making something happen. So, I like to say engineers build what's never been built before, so scientists can discover what's never been discovered before. So, we work as a team here at NASA to make that possible.
