Lunar Prospector Status Report #66

January 22, 1999 - 1:00 p.m. EST (10:00 a.m. PST)

The Lunar Prospector spacecraft is operating well and all instruments continue to collect good data.

On Jan 19, the GRS high voltage gain was tweaked. Also, the APS instrument was commanded to investigate an ongoing noise/saturation problem with two of the instruments five faces. At the end of the test, face #5 was commanded off, to prevent it from saturating the other four faces. A total of 8 commands were sent.
