Mars Global Surveyor is the oldest of five NASA robotic devices, which is designed to find out signs that Mars once had water; and it had been taking detailed pictures of the red planet for a decade. Unfortunately, it stopped working on November 2 after it developed a motor problem. After two days of silence, ground control teams received a signal that the device had put itself into an emergency standby mode. There was no information about what had gone wrong. Since then, the mission team at NASA's laboratory in California has tried to contact the device. This week, NASA engineers are preparing for what may be their last chance to recover the spacecraft. NASA plans to use a newly arrived device to take a picture of the Surveyor to see how the failed craft is oriented to the sun for power and to Earth for communications. It is reported that the picture will be taken on Friday when the satellites are about 93 miles apart. The new high-powered camera should be able to image details of the Surveyor as small as about 10 centimeters. There is a good chance of recovering it.
