Cosmic Journeys: The Asteroid that Flattened Mars (2009)

SpaceRip TV

At the end of January, 2008 a large asteroid identified as 2007 WD5 could have struck the planet Mars. This rock traveled 27,000-30,000 miles per hour and measures some 50-meters or about the size of a small size apartment building. If it had struck Mars, it would be near the equator, not too far from the Opportunity Rover's location, with a blast equivalent to a 3-megaton atomic bomb carving out a half-mile wide crater and throwing a lot of ground material into the atmosphere.

Documentary Description


Aug 19, 2009 — Season 1 Ep. 3 — Just about every two years, the planet Mars makes its closest approach to Earth around 36 million miles. Thats when we pack our robotic emissaries off to the Red Planet, timing their launches to spend the least effort to get there. These probes may pave the way for human explorers and, perhaps permanent settlers wholl dig deeper still in search of answers to our most pressing question: Did Mars develop far enough and stay that way long enough for life to arise?
