Notes From Bacalar: The Little Spaceship That Could

The Mars Global Surveyor has stuck around beaming its' information back to Earth, "Hello, Houston," longer than any other human artifact sent to Mars. Therefore, we are not surprised that it sent back "more information about Mars than all earlier missions combined." The persevering little ship has been around long enough to see two more orbiters arrive -- Mars Odyssey and Mars Reconnaissance Orbiter. Friday, 17 November, NASA was reported by Yahoo News to have enlisted the aid of one of those two, new orbiters, the Mars Reconnaissance Orbiter, the most powerful probe ever sent to mars, in the effort to save Surveyor. Reconnaissance has scanned the area where Surveyor may be in an effort to locate it. Since it seems to be waiting to receive a signal telling it to point one of its' redundant transmitters toward Earth, finding it could help get it a clear signal. It will be next week before the scans can be read to see if Surveyor has been found. JPL's description of The Little Spaceship That Could tells of a vehicle that is about 10 feet (3 meters) tall and, when it has its' solar panels deployed, it is 40 feet wide. It weighed 2342 pounds when it was launched but has lost some weight over the years unlike some people I know. It was put together with some spare parts from an earlier spaceship, the Mars Orbiter. To minimize costs, spare units left over from the Mars Observer mission were used in portions of the spacecraft's electronics and for some of the science instruments. The spacecraft design also incorporated new hardware - the radio transmitters, solid-state recorders, propulsion system, and composite material bus structure-and retains many backup and redundant features of the original Mars Observer design in case of failure of critical elements such as the primary processors, recorders or transmitters. The probable culprit in the loss of our little Surveyor is connected to its' antenna and communications system These are a "1.
