Go no more a' Roving

The Mars Spirit Rover is stuck for good. But NASA can't really complain, since the original mission length was just over 3 months and the rover kept going for over 5 years. And it will still keep reporting as long as its batteries hold out and the solar panels work, it just won't be moving.

Good job, little robot!

Update: xkcd has a slightly darker take. "I thought I analyzed that rock really well."
