I read about this a few days ago. I was sad to hear that they're canning the program, especially since they've put a ton of money into it already. I've met many people who have spent the last few years of their lives designing, building, and testing the Ares rocket, and working on the crew capsule as well.
Still, I agree that getting private companies more involved in space travel is good, but I also doubt the government's ability to succeed in doing it. And when I found out that they're putting the money towards global warming... Well, I wasn't happy about that either.
