That's an amazing accomplishment, and it's where our focus should be in space exploration. Let's stop this nonsense about manned exploration. Putting a human on a heavenly body not our own was a worthy goal -- we've accomplished that. Sending humans to Mars is a pointless endeavor. They'll be so damned weak from radiation, if by some miracle they even make it there, that the best they could do is plant a flag. And, they ain't coming back. We can learn so much more, and much more cheaply, by using robots for our space exploration. And yes, I am in complete agreement that our defense budget is obscene and dwarfs the space budget, but that doesn't justify this silly goal of sending humans to Mars (or back to the Moon).
But, but, ... what about overpopulation? Deal with that the sensible way on Earth, rather than sending people to die on another planet. The Space Shuttle era was absurd:
