Check out this image taken from the Spirit Mars Rover. Having landed in January 2004, Spirit’s still trucking along, and it’s just beamed back this picture from atop “Husband Hill.”
Both rovers have lasted about 17 months beyond their original mission. And Spirit is in especially fine form, operating at a power level of 950 watt-hours of electricity per day. That is only 10 watt-hours less than it had after it landed – gusts of wind have probably blown accumulated dust off its solar panels to keep them operating well.
