Mars rover loses a wheel, but keeps on going

Spirit, one of the two Mars Rovers, has lost function in a wheel. Despite this problem, the rover will still keep rolling along.

The two mars rovers were expected to function for only 90 days. Today, the mission is on its second year.

If only we could expect this sort of performance out of cars.

I found the location of Spirit on Google Mars, which features a nifty page showing spacecraft landing sites.
