Spirit Rover has no Spirit
NASA, the people who give us such great things as 17 moon rocks and supersmooth ball bearings, announced today that the Spirit Rover, toodling around in Gusev Crater on Mars, has stopped toodling. Or, at the very least, it has stopped announcing what it's doing when it's toodling.

This can only mean one of two things: We have discovered life, and it's pissed off, or the Rover had an accident with the Beagle 2 and they're both still trading insurance information.
