I have to believe that their first through eighth choices weren't available, because it's the only thing that makes sense, but somehow I was chosen to be the host and narrator of a video for, among other outlets, NASA TV, that explains how Curiosty gets to the surface of Mars, and what she'll do once she's there. It's pretty incredible stuff, and I am still astonished that I was chosen to be the guy.
While I was at JPL, I got to get up close and personal with the full-scale replica of the rover that stays on Earth while her sister goes to Mars, so I took a few pictures:
I grew up about 10 minutes from JPL, so I lived around a lot of NASA sceintists and went to JPL's open house every year. Being chosen to go to JPL to make the modern equivalent of the films I loved watching when I was a kid was a tremendous honor. I'll post the video I made whenever it's live.
