Apollo 13: To the Edge and Back "I could see a gaseous substance escaping...That's when it definitely occurred to me that we were in deep trouble...Very shortly, we'd be completely out of oxygen." These were the thoughts of James Lovell and the rest of the crew of the Apollo 13 as they heard the ominous explosion that robbed them of most of their oxygen, food and water - 200,000 miles from Earth. Apollo 13: To the Edge and Back tells the gripping, true story of the catastrophic flight of the Apollo 13 and the heroic struggle to bring the astronauts back alive. With first-hand accounts from the pilots, their families, and the people of mission control, it documents a thrilling struggle against time and all odds and serves as a reminder that, in the words of James Lovell, "We do not realize what we have on Earth until we leave it."

MARS Dead or Alive Two-thirds of all spacecraft previously launched to Mars never reached their destination. Now, in a pioneering and risky mission, twin rovers named Spirit and Opportunity hurtle towards Mars at 12,000 miles per hour, with Spirit scheduled to touch down first. Only then will Spirit be able to roll off the lander and begin its mission as a robot geologist, searching for clues that can tell us whether this harsh and barren planet was ever a place that could have supported life.
