re: And Bush is?
What do you base this on? Bush only showed interest in the space program after STS-107 and 3 years into his reign. I wouldn't take articles written by people who will be putting out a book on the subject (and thus benefiting from the promotion of the idea) as proof of Bush's commitment. He never showed the slightest interest when he was governor and he made a plan that doesn't even really start till he is out of office. And Mars and beyond was supposedly an after thought by him.
