NASA Spirit Rover Completes Mission on Mars

This recent news can be seen as a positive and a negative. Just in case the title wasn't clear, one of NASA's rovers called Spirit is officially done on it's mission. Although Spirit's twin, Opportunity will be staying on the red planet and help scientists with their on going research. The negative component to this news is that now NASA only has one operating rover on Mars, but the positive is that Opportunity has done more for them anyways, so if they had to lose one, they picked the better one.
