Introduction
=============================================================================
This bundle contains Derived Lunar Prospector Electron Reflectometer time
ordered values of derived quantities from electron reflection, including
calculated effective electron reflection coefficient from dates
1998-06-08 to 1999-06-27.
This bundle is organized into several collections, including:
browse, data-electrons and document. PDS4 documentation is in all XML.
There is an XML label for every product in the archive.
This bundle is intended for the use of scientists and students in the study
of solar wind and planetary energetic and neutral particles. The data may be
used for research and publication.
Every effort has been made to insure that the data are of the best quality
available. However, users are encouraged to verify the correctness of the
data prior to submitting any publications or other work based on these
data and report any issues to PDS/PPI.
This bundle was migrated to PDS4 from the PDS3 data set:
LP-L-ER-4-ELECTRON-DATA-V1.0 (https://10.17189/1519721).
These data were originally archived under PDS3 in the following volume:
LP_2001.
This bundle complies with Planetary Data System 4 (PDS4) standards.

Brief Bundle Description
=============================================================================
Lunar Prospector (LP) was a simple spin-stabilized spacecraft with a nominal
spin period of 5 seconds, operating in a circular, polar orbit around the
Moon. The orbit during the Primary Mission had a 118 minute period and
average altitude of about 100 km. The Primary Mission lasted for one year
starting on January 16, 1998 and ending on January 16, 1999. The spacecraft
orbit was then lowered to about 30 km to acquire higher resolution data
during a 6-month Extended Mission. The Extended Mission began on
January 16, 1999 and was completed on July 31, 1999. The mission ended when
the spacecraft impacted into the surface of the Moon.
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, housed on three booms: a gamma
ray spectrometer, a neutron spectrometer, an alpha particle spectrometer, a
magnetometer, and an electron reflectometer. In addition, a gravity
experiment used Doppler tracking data to derive gravity measurements.
This bundle includes Lunar Prospector Electron Reflectometer (ER)
(NASA Level 2 Data, CODMAC Level 4).
