I'm all for expanding frontiers of science. I'd much prefer sending robotic exploration craft, though. I don't see much scientific gain coming out of putting the people in space, while the massively increased costs associated of keeping people alive and well in space just subtract from scientific gains in knowledge and exploration. Putting people in space is for PR, putting robots in space is for science.
