The International Space Station is a technical marvel, unparalleled in scope and challenge.

Space Station is the story of the unique partnership of 16 nations building a laboratory in outer space—a permanent facility for the study of the effects of long-duration exposure to zero gravity and the necessary first step toward the global cooperative effort needed if humans are to someday set foot on Mars.

It is a story of challenges, setbacks and triumphs—and ultimately, the shared international victory of people whose dreams exceed the limits of life on Earth. Narrated by Tom Cruise.
