TV-viewers around the world will be treated to an unprecedented live tour of the $100 billion International Space Station next month when the National Geographic Channel airs a two-hour special from the astronauts’ orbital home.

During the “Live from Space” TVevent, NASA astronaut Rick Mastracchio and Japanese astronaut Koichi Wakata — two of the six spaceflyers currently living on the station — will show how they stay fit, conduct science experiments and even use the toilet in microgravity. They’ll also talk to viewers via videochat, according to Nat Geo. Meanwhile, veteran NASA astronaut Mike Massimino, who is perhaps most famous for his spacewalking repairs the Hubble Space Telescope, will be partaking in the two-hour event, live from Houston.
