John Glenn became the first American to orbit the Earth during the height of the space race. He was a pioneer, an aviation icon and American hero. For 50 years, America has led the world in space exploration. Yet the boundless void that begins just 62 miles above us has been visited by no more than 500 people. “WHEN WE LEFT EARTH: THE NASA MISSIONS” is a stunning high-definition exploration from Discovery Channel that opens up space like never before.
The missions, the people and the triumphs of exploration are revealed in a depth of detail previously experienced only by Glenn and the other astronauts. The episode features interviews from Mercury and space shuttle astronauts including first-person accounts from Glenn and what it was like to be part of history. Be sure to check out his journey and tune in for this special encore presentation only on Discovery.
