So this is where our tomorrows begin: 220 miles above the Earth and moving at a speed of 17,500 MPH while aboard the most complex scientific project ever assembled: the International Space Station (ISS). Tom Cruise narrates this fascinating look at the high-flying laboratory where today's space heroes develop technologies that will make possible human voyages to Mars as well as provide new solutions to earthbound problems. Highlights include the station's in-orbit construction, plus amazing glimpses of crew members as they work, exercise or do routine tasks like getting a haircut or drinking water (in zero gravity, you can snap a floating glob of H2O out of the air like a frog snatching a fly!). Suit up, travelers!
