I love this country. I love the American idea. I have profound disappointments in my country. I feel we ought to be in space … because it meant so much to us … technologically. It moved us along.”

We are “in space.” We have a space station, we have at least two, maybe three manned spacecraft in development, to fly in two or three years (not even counting NASA’s wasteful efforts that won’t fly with humans until the end of the decade at best), we just got an announcement of a serious plan to send two people to Mars within five years. What more does he want?
