Mars Rising [2 Discs]

"As originally co-produced by The Discovery Channel and Arte and co-financed by Canadian interests, the six-part, 6 1/2-hour documentary series From the Earth to the Red Planet draws from contributions by over 300 scientists and other experts to speculate on the challenges behind a manned mission to Mars. The program posits this as perhaps the single most dangerous of all 21st Century expeditions. Titanic and Avatar director James Cameron turns up for commentary. Installments include ""Journey to the Red Planet,"" ""Rocket Power,"" ""Staying Alive"" and more."
