You mentioned that the Obama administration is advancing around $6 billion toward that. Ironically, that is the implementation number for the HST. It is choices.
I would like to know why, in your perspective, no one has gone back to the moon. It's been trumped as a significant achievement for mankind, of course, but Obama is looking more to Mars, and so forth. Why has no one else gone back to the moon? Is there no significant value, aside from just the optics of it, or is there more of a desire to get to Mars, thinking there could be some benefits there?
I think what you did was important. You really touched on some very practical elements when we were talking about the different gaps here. People don't realize that. If you're walking around the grocery store and talking to people, why should we go into space? You've got some very practical things that make a lot of sense, things that people tie to their daily lives.
Why Mars versus the moon?
