The International Space Station is roughly the size of a football field with a sizable 30,000 cubic feet of pressurized space inside. Watch this video to take an in-depth tour of the Station.
On her last day as the commander of the space station Sunita Williams put together a grand video tour of the station, visiting all the modules, docked craft, and everything in between. The video is fairly long at 25 minutes but worth the watch. Prepare to be surprised at just how much space and equipment there is in the ISS.
