EXPEDITION MARS brings to life one of the greatest sagas of the Space Age - the epic struggle to get the Spirit and Opportunity rovers safely to Mars, and their astounding journeys of exploration once they finally got there. On Mars the rovers continued beating the odds, cheating death many times as they turned their modest three-month mission into the first great overland expeditions on another planet. Watch never before seen footage from the archives of the Jet Propulsion Laboratory, first person recollections by mission scientists and engineers and vivid, realistic animation of the rovers in the actual terrain they explored on Mars.
