Lunar Prospector archives at the
Geosciences Node have been migrated
to the PDS4 standard. This includes
calibrated GRS and NS data,
GRS elemental abundance tables, and
spherical harmonic gravity models.
The original PDS3 data products,
labels, and documentation remain
available in their original archive
volumes. The only change is that
PDS4 labels and documentation have
been added to the archives. The
original data files are unchanged.
(LP) was a spin-stabilized spacecraft, operating in a
100 km circular, polar orbit around the Moon during its
Primary Mission in 1998. The orbit was lowered to 30 km
for the Extended Mission that began in January 1999. The
mission ended on July 31, 1999, when the spacecraft
was targeted to impact a crater near the lunar south
pole to try to vaporize part of the suspected water
The science goals of LP were to map
the Moon's surface composition and its magnetic and
gravity fields, to determine the frequency and location
of gas release events, and to search for polar ice
deposits. To meet these objectives, LP had five science
instruments located on three booms: a gamma ray
spectrometer, a neutron spectrometer, an alpha particle
spectrometer, a magnetometer, and an electron
reflectometer. In addition, Doppler tracking data was
used to derive gravity measurements.
The preliminary science
results from Lunar Prospector have been published in the
September 4, 1998 issue of
Science. Also, a detailed description of the Lunar
Prospector spacecraft is available in the
LP Mission Handbook document
(Adobe Acrobat format file; 760 KB).

These files are not part of a PDS archive but are
provided as-is because of interest expressed by
