The other, Spirit, is stuck, possibly in a hibernation mode, and could "wake up" during the Martian summer solstice , this coming March. It’s pretty incredible that these rovers operated so long after they landed – in Opportunity's case 20 times longer and counting.
And, orbiting above the rovers is the Odyssey spacecraft, which last week broke the record for longest-working spacecraft at Mars. The previous record was set by NASA's Mars Global Surveyor, which orbited Mars from 1997 to 2006.
And amidst all this history, a little under a year from now, the Mars Science Laboratory Curiosity will be launched and is scheduled to land in August 2012. Curiosity is also a rover, but is larger than either Opportunity or Spirit. Its mission is to assess whether Mars ever was, or is still today, an environment able to support microbial life.
