Long-Silent Mars Lander Appears to Be Officially Lost

It looks like it really is the end for NASA’s Phoenix Mars Lander, which spent five months digging in the Martian arctic before succumbing to the icy winter conditions that set in at the end of its mission.
The third and final attempt to listen for any signs of survival from the lander, conducted last week, didn’t turn up a peep.
Phoenix landed on Mars on May 25, 2008, and operated successfully in the Martian arctic for about two months longer than its planned three-month mission, which confirmed the presence of water ice under the Martian surface. But once the sun and temperatures dropped and winter set in, the spacecraft didn’t have enough power to keep going. The lander went silent in November 2008.
