Phoenix Mars Explorer Finished it job

NASA’s Phoenix Mars Lander has ceased communications after operating for more than five months. As expected, seasonal decline in sunshine at the robot’s arctic landing site is not providing enough sunlight for the solar arrays to collect the power necessary to charge batteries that operate the lander’s instruments. Last signal from the Phoenix was received on Nov.2nd. Launched Aug. 4, 2007, Phoenix landed on Mars on May 25, 2008. It verified the presence of water-ice in the Martian subsurface. Phoenix findings also support the goal of learning the history of water on Mars.
