Defying Gravity | Rotten Tomatoes

An international crew of eight astronauts -- four men and four women -- sets off on a mysterious, six-year mission covering billions of miles aboard a ship called the Antares. Inspired by the fictional docudrama "Space Odyssey: Voyage to the Planets," the show tells the story of both the astronauts as they explore Venus and the other planets in the solar system, and their supportive and dedicated ground crew. Episodes alternate between the present, on the current mission, and flashbacks to earlier years when the final eight were still in the grueling selection and training process.
