What's it like to live in space? As this new NASA video shows, you get to float around, talk to folks on Earth, and your personal space is not much bigger than you are.

Koichi Wakata, an astronaut with the Japanese space agency JAXA, gives a little tour of the crew quarters in one of the International Space Station's modules, which he describes as "a really neat place and comfortable to live in." Of course, Wakata is a pro at this kind of thing, having a two-decade career in spaceflight, including four space shuttle missions and a previous stay on the ISS. He shows off a fairly cramped personal space, about the size of an old-fashioned telephone booth.

Inside is a sleeping bag affixed to the wall, which keeps astronauts from flying around and knocking into anything when resting. Wakata gets two computers, one for official business and scheduling and another with internet access, from which he tweets incredible photos of the Earth. He is also able to place personal calls to family and friends with the help of a camera and headphones.

Astronauts on the space station spend much of their time conducting experiments, especially those related to the changes occurring in the human body in zero-g. NASA and other space agencies are trying to figure out how to combat long-term degenerative problems such as blindness and bone loss that serve as impediments to long duration spaceflight.

After the next space station crew changeover happens in May, Wakata will become ISS commander, the first JAXA astronaut to hold this position.
