Well, NASA's Mars Rover Spirit is officially permanently stuck in the Martian soil. It's still alive so NASA is using it as a "stationary science platform." They expect it to continue to be alive for months longer, and possibly even years. It has already greatly outlived it planned life expectancy of at least 90 days. The rover has been on Mars since 2004.
I am thinkin' 'bout hopping in my truck and takin' a ride to see what I can do. Anyone want to join me?
