摘要

The recently-started Mars Global Surveyor (MGS) full-scale map- ping mission has been put on hold due to a problem with a gimbal mechanism which controls movement of the spacecraft's 1.5-meter high-gain antenna. The problem was detected about 9:30 p.m. PST on Apr. 15 when Deep Space Network (DSN) officials reported the spacecraft was transmitting at a low-data rate rather than a planned high rate of data. MGS flight controllers at NASA's Jet Propulsion Laboratory (JPL) and Lockheed Martin facilities near Denver found the spacecraft had automatically placed itself in a "contingency" mode, during which science instruments are shut down and the spacecraft communicates with its low-gain antenna.
