The Lunar Prospector spacecraft position data set consists of spacecraft position determinations in selenographic latitude, longitude, and altitude coordinates in one minute intervals. The data set also contains spacecraft velocity and distance from the center of the Moon as a function of time. The coordinate system is selenographic with east longitude positive. The data set is generated by the Goddard Flight Dynamics Analysis Branch.

Trajectory data for the Lunar Prospector spacecraft in Selenographic, SSE, GSE, and GSM coordinates. Dataset covers dates 1998-01-16 to 1999-07-29.

This bundle contains ephemeris support data (spacecraft state vectors, camera orientation, photograph position, and lighting data) computed during the Apollo era for analyzing and using photographic images taken of the moon from 30 July to 4 August 1971 by the Apollo 15 Metric (Mapping) and Panoramic Cameras from lunar orbit. This bundle also includes digital scans of the original tabular data output on microfilm.

This bundle contains ephemeris support data (spacecraft state vectors, camera orientation, photograph position, and lighting data) computed during the Apollo era for analyzing and using photographic images taken of the moon on 10-16 December 1972 by the Apollo 17 Metric (Mapping) and Panoramic Cameras from lunar orbit. This bundle also includes digital scans of the original tabular data output on microfilm.

The sun pulse data set is a record of times that the Lunar Prospector sun sensor detects the Sun. These sun pulse times are derived from ground processing of the sun sensor data, earth-moon limb sensor data, and the spacecraft ephemeris. This data set is part of the Lunar Prospector Level 0 data archive. The sun pulse times are used in determining the spacecraft spin rate and orientation as a function of time. Because the Lunar Prospector spacecraft is sometimes in eclipse with the Sun, the sun pulse data set is generated on the ground to include both actual sun pulse times based on the sun sensor measurements and estimated sun pulse times based on the history of spin rate change during all prior eclipses.

This dataset contains calibrated, 1.05- to 4.8-micron spectral images of the Moon acquired the High Resolution Infrared Spectrometer (HRII) from 29 December 2007 through 18 December 2009 during several in-flight instrument calibrations for the EPOXI mission.

The Lunar Prospector attitude data set consists of values for the spacecraft spin rate and spin axis orientation (attitude) as a function of time. These values are determined from spacecraft attitude data (sun and limb crossing sensors) and ephemeris data. Spacecraft orientations are given as right ascension and declination of the spacecraft spin axis in the Mean-of-J2000 Ecliptic reference frame. The attitude data set consists of a single, cumulative file for the entire mission. Records are added to this file following each significant change in either the spin rate or spin axis orientation. The spacecraft spin rates and attitudes in this data set are orbit averages. The instantaneous spin rate can be determined from the sun pulse data set. The instantaneous spin rate varies as the spacecraft passes into and out of the Moon's shadow and after each spacecraft maneuver. Generally, an attitude record is included for times immediately before and after each maneuver.
