This week, NASA announced that Spirit, one of the twin Mars Exploration Rovers, appears to be permanently stuck in Martian soil, and that the rover would now be used only as a stationary observation platform. "It looks like Spirit's current location on Mars will be its final resting place," said Doug McCuistion, director of NASA's Mars Exploration Program. The announcement comes as both rovers prepare to enter a period of Martian winter. We'll talk with Steve Squyres, a researcher at Cornell University and principal investigator for rovers Spirit and Opportunity, about the Mars mission and what lies ahead.
