No Lack of Spirit for 'Spirit' as Mars Rover Struggles

Monday, January 04, 2010

The Mars rover "Spirit" has overcome many mechanical problems since it landed on the red planet six years ago for what was scheduled to be a 90-day mission. There have been computer failures, terrain trouble, and now, Spirit is stuck in a Martian crater, though still taking measurements. Engineers are trying to find a way to get the rover free while its sister, "Opportunity," rolls happily along on the other side of the planet. We speak with Ray Arvidson, deputy principal investigator on the Mars Rover Exploration mission and a professor of earth and planetary sciences at Washington University in St. Louis.
