Universe Today reports Mars Rovers Set Surface Longevity Record.
"Congrats to the science and engineering teams for the Mars Exploration Rover program! Today, (Thursday May 20) the Opportunity rover marked an historic milestone: it has now passed the duration record set by NASA's Viking 1 Lander of six years and 116 days operating on the surface of Mars. The celebration was tempered just a bit because Oppy may be the longest lasting mission on Mars, or it may be second to its twin, Spirit. Spirit has not communicated with Earth since March 22, succumbing to the cold and decreased power from its solar panels. If Spirit awakens from hibernation and resumes communication, then she will attain the Martian surface longevity record."
Not bad for landers originally planned to function 90 days! More details at NASA.
