Martians Shot Down MGS?

Engineers are striving to restore full communications with NASA's Mars Global Surveyor on the 10th anniversary of the spacecraft's Nov. 7, 1996, launch.

The orbiter is the oldest of five NASA spacecraft currently active at the red planet. Its original mission was to examine Mars for a full Martian year, roughly two Earth years. Once that period elapsed, considering the string of discoveries, NASA extended the mission repeatedly, most recently on Oct. 1 of this year.
