Lunar Prospector
|
February 2, 2021. Lunar
Prospector PDS4 Archives
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.

Lunar Prospector (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
deposits.
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).
