Before man makes it to Mars, he must conquer the Arctic. Passage to Mars is the incredible true story of six men who embark on a treacherous, 2,000-mile journey across the forbidding tundra of the Northwest Passage-an alien voyage on planet Earth designed to prepare NASA astronauts for an eventual mission to Mars. But as an expedition that was supposed to take weeks stretches into a two-year odyssey, the crew must overcome seemingly insurmountable challenges and life-threatening conditions if they hope to realize their dreams of someday reaching the Red Planet. This breathtaking adventure features narration by Zachary Quinto and special guest voice appearances by Buzz Aldrin and Academy Award (R) nominee Charlotte Rampling.
