Brief Volume 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 volume includes a record of all commands sent to the Lunar Prospector
spacecraft.
Every effort has been made to assure that the data included on this volume
are of the best quality available. However, the PDS and the Planetary Plasma
Interactions (PPI) Node in particular, assume no liability for this volume or
its contents. All users are encouraged to verify the "correctness" of the
data prior to submitting any publications or other work based on these data.
All data files are stored in the "DATA" branch of the directory tree.
=============================================================================
File Formats
=============================================================================
Detached version 3.x PDS labels describe all files on this volume.
PDS labels are identified by a ".LBL" file name extension. There is one label
file for each text and data file (1 flatfile) contained on this volume and
the file name prefix is the same as the file the label describes. If the
dataset is stored as multiple files (as most of them are), there will be a
single format file which describes the physical structure of the data. This
format file is then pointed to by all of the labels. Both the label files
and the format files (*.FMT) are all located in the same directories as the
data they describe.

Errata
=============================================================================
Every effort has been made to assure that the data and documentation are of
the best possible quality. However, mistakes are inevitable. The PPI Node
of the PDS will maintain an online list of ERRATA where errors and updates
are documented. Should any user of this product find an error on this
volume, please report the error to the PPI Node so that the finding can
be made public. All users are encouraged to verify the correctness of the
data prior to submitting any publications or other work based on these data.
There is a file called ERRATA.TXT found at the root level of this volume
which contains a list of known deficiencies or caveats associated with data
on this volume at the time that it was produced.
If you find an error on this volume, please report it to the PDS Operator at
the PPI Node of the PDS (contact information below).

The original CD volume set, from which this dataset was prepared, was
designed and produced by Edward A. Guinness from Washington University,
Marcie Smith from NASA Ames Research Center, and William Jacobsen from
Lockheed Martin. The data were reorganized into the present dataset at the
PPI Node of the PDS.
