The golf cart sized Spirit Rover has been on Mars since January 2004. Six years later, Spirit and it's twin, Opportunity, have far exceeded their initial 90 day mission. But the Spirit rover is in trouble. The right front wheel was disabled in 2006. And now the back right wheel is stuck in sand and stalling. The back wheel has been stuck in the sand for 8 months. The wheel stalls have been complicating efforts to free the rover. Now that the rover has only 4 operable wheels, it may be stuck at it's current location until the beginning of the Martian winter. If that happens, the rover is not likely to recover.
Call a tow truck and a garage. Or a good buddy with some tools (Opportunity?). Aren't there tools on those things?
