While recent attention for Mars exploration has been focused on the Mars Phoenix Lander, we shouldn't forget that we also have the Mars rovers roaming around the planet. Nearing their fifth year on the planet, the rovers are still operational. In fact, the Opportunity rover has just climbed back out of Victoria Crater that it went in to study nearly a year ago. As it left the crater, it took one last look at the way it came from.
With Phoenix expected to be encased in carbon dioxide ice during the Martian winter, it will probably be outlived by the much older rovers.
