Google Tech Talk featuring an astronaut who spent 6 months in the International Space Station. Some interesting stuff is discussed here if you're into this topic. He talks about the experiments he did, recovering from returning, shares a bunch of photos from the trip, describes what it's like living in a 1200 sq. foot can for 6 months with two other people, and goes into the training required for the job. I don't think they're allowed to play World of Warcraft up there though.
