Lunar Prospector Status Report #29

April 24, 1998 - 1:00 p.m. EST (10:00 a.m. PST)

The Lunar Prospector spacecraft continues to perform very well.

A recent increase in solar activity has been associated with an increase in particle counts from the Alpha Particle Spectrometer (APS) over the last couple of weeks. This effect will be compensated for in the course of the ongoing data analysis.

Current spacecraft state (00:00 4/23/98 GMT):

Orbit: 1225
Downlink: 3600 bps
Spin Rate: 11.96 rpm

Spin Axis Attitude (ecliptic):
Latitude: 83.2 deg
Longitude: 94 deg

Trajectory:
Periselene Alt: 81.8 km
Aposelene Alt: 118 km
Period: 118 minutes

Occultations: 46 minutes
Eclipses: 46 minutes

An attitude reorientation maneuver is scheduled for Monday, 4/27, with a maneuver test pulse firing scheduled for Friday, 4/24.
