Follow Commander Williams as she glides weightlessly through the station’s interconnected modules, research labs, and living quarters. From the Japanese laboratory to the European Columbus module, Williams offers a comprehensive tour of astronaut life in orbit. She demonstrates how crew members sleep in phone booth-sized quarters, exercise on specialized equipment to prevent bone loss, prepare meals in the international kitchen (stocked with American, Russian, and Japanese food), explains use the ‘orbital outhouse,’ and visits the lab’s airlock where to spacesuits are ready in case the astronauts need to go on a spacewalk.

There is nearly 16,700 cubic feet of habitable area aboard the International Space Station (ISS). That makes it larger than a six-bedroom, two-bathroom house,but still small enough for a grand tour that takes less than 15 minutes. That doesn’t mean there’s nothing worth seeing.
