NASA Loses Contact With Mars Global Surveyor

NASA’s Mars Global Surveyor (MGS) spacecraft has failed to check in with Earth for the fifth straight day in a row, after losing contact during a routine adjustment of its solar array.
If contact is not reestablished by Saturday, NASA might try to have another Mars-orbiting spacecraft take pictures of MGS to assess its condition.
On Nov. 2, MGS mangers sent commands for the spacecraft to adjust the position of one of its solar power arrays to better track the sun. Returning data indicated a problem with the motor that moves the array, so a backup motor and control circuitry were switched on.
No signal was received on Nov. 3 and 4, but a weak signal was received on Nov. 5, suggesting the spacecraft had switched to a safe mode and was awaiting further instructions from Earth. The signal cut out completely later that day and nothing has been heard since.
