In this documentary, astronauts from the Kennedy Space Center complete intensive training, say goodbye to their loved ones, launch and meet cosmonauts from the Baikonur Cosmodrome 220 miles above the Earth, where they work to complete the International Space Station, a permanent laboratory designed to study the long-term effects of human exposure to zero gravity. The team struggles with procedures as dangerous as they are delicate, all while orbiting Earth at a speed of 17,000 miles per hour.
