Since the dawn of mankind, we have stared up at the lights in the sky and wondered... Now join the heroic men and women who have dared the impossible on some of the greatest adventures ever undertaken - the quest to reach out beyond Earth and into the great unknown of space! To celebrate 50 years of incredible achievements, the Discovery Channel has partnered with NASA to reveal the epic struggles, tragedies and triumphs in a bold chapter of human history. Along with the candid interviews of the people who made it happen, hundreds of hours of never-before-seen film footage from the NASA archives - including sequences on board the actual spacecraft in flight - have been carefully restored, edited and compiled for this landmark collection. "Ordinary Supermen" - NASA selects seven men to become the first astronauts. They're all test pilots, prepared to risk their lives. No one has ever survived a vertical launch on top of a rocket, but it's the only way they know to put an astronaut into earth orbit. NASA and America's first astronauts, the Mercury Seven, are on a journey into the unknown. Six of the men ride into space, each launch taking NASA further forward in their quest to conquer space. "Friends and Rivals" - Nine new astronauts arrive at NASA - their mission, to test all the procedures required to land men on the moon and bring them safely back to earth. Each Gemini mission launches two men into space, leading to some of NASA's greatest moments - Ed White's spacewalk, the first orbital rendezvous of Gemini 6 and 7, and Neil Armstrong's first space docking. "Landing the Eagle" - The Apollo program is set to achieve the ultimate prize of the Space Race, landing men on the moon. But a fire breaks out in the pressurized capsule of Apollo 1, resulting in the deaths of three beloved astronauts. However, NASA rebounds, launching men into deep space and landing Neil Armstrong and Buzz Aldrin on the moon. "The Explorers" - Apollo 13 puts the astronauts to the ultimate test, returning a damaged spacecraft back safely to earth. Apollo 17 sends man for the longest mission yet to the surface of the moon, but it's the last lunar mission for generations. Now, it's time for a new phase in the program. Converting an unused Saturn V rocket, NASA launches Skylab, America's first space-station. "The Shuttle" - For its first 20 years, NASA launches capsules carrying a maximum of three people. But new requirements for a bigger cargo bay prompt a breakthrough in spacecraft design. The development of the re-usable shuttle leads to a revolutionary approach to space travel. Meanwhile, the pioneers of NASA's manned programs are leading the way into the modern era of the space-age. "A Home In Space" - One of the most complex instruments ever built, the Hubble Space Telescope is expected to transform our understanding of the Universe. But once it is in orbit NASA discovers a serious problem, a defective main mirror. NASA sends a team of astronauts to fix the problem in its greatest and highest profile mission since the Apollo era. It gives NASA the confidence to begin construction on the International Space Station.

Four hours of bonus features including digitally restored NASA film highlights, mission clips, and astronaut interviews.
