Astronaut Sunita Williams, who commanded Expedition 33 on the ISS, spent her last day putting together this video tour, and it's (wait for it) out of this world.
They say that in space, nobody can hear you scream. What they don't say is that it's because it's damn loud up there. Astronaut Chris Hadfield recorded the ambient noise aboard the International Space Station and sent it back down to Earth to give us all a sense of what it's like.
This is Detailed Secondary Objective 469, aka the In-flight Radiation Dose Distribution experiment, aka a human skull that was flown on three space shuttle missions and used to measure radiation in space. So, what do you do if you're a bored astronaut and you have this creepy thing floating around?
NASA takes the lives of its astronauts very, very seriously. Dr. Robert Zubrin, author of The Case for Mars (which advocates for a one-way trip to Mars with reliance on local resources for a return), argues that the premium NASA places on safety is crippling the agency, and that "the mission has to come first."
It can be argued we spend so much time focusing on what astronauts do once they get in their spacecraft and make it up in space, we forget the thousands of hours that go into testing everything the astronauts will touch, do and even wear. The following video is a fun look at early spacesuit testing, showing different models being put through their paces.
Becoming an astronaut isn't a cakewalk. You have to be somewhat smart and super fit. You are going to space, y'know. But if you're a Chinese female looking to go up to the final frontier, you'd better be married and not smell, or you won't be qualified.
