David Shiga writes "Just when NASA was about to celebrate the 10th anniversary of the Mars Global Surveyor (MGS) spacecraft, the probe suddenly lost contact with Earth, New Scientist Space reports. NASA last heard from the MGS probe on November 5, two days before the 10th anniversary of its launch from Earth. The MGS team is not sure yet what the problem is, but a micrometeorite could have jolted the spacecraft's main antenna out of alignment with Earth, or it might have a solar array problem and too little power to talk to Earth as a result. If they can't re-establish communication this week, NASA may try to diagnose the problem by taking pictures of MGS with the Mars Reconnaissance Orbiter. The two spacecraft come within about 100 kilometers of each other several times each week."
