urn:nasa:pds:a12sws_solar_wind_28s_1hr:document:a12_lunar_gse_coordinates 1.0 1.23.0.0 Product_Document 2025 This file provides the Geocentric Solar Ecliptic Coordinates (GSE) of the Moon from 18 November 1969 through 26 March 1976. This information may be useful when analyzing data from the Apollo 12 Solar Wind Spectrometer. The file includes the X, Y, and Z GSE coordinates for the Moon in units of kilometers as well as the GSE latitude and longitude in degrees. The time resolution is 1728 seconds (1/50 of a day). The GSE system has its X-axis pointing from the Earth toward the Sun and its Y-axis is chosen to be in the ecliptic plane pointing towards dusk (thus opposing planetary motion). Its Z-axis is parallel to the ecliptic pole. Relative to an inertial system this system has a yearly rotation. Position is from Earth's center of mass to Moon's center of mass. The GSE coordinates in this file were generated by the Satellite Situation Center (SSC) at Goddard Space Flight Center on the SSCWeb (http://sscweb.gsfc.nasa.gov/). 2025-09-26 1.0 Initial version. 1969-11-18T00:00:00Z 1976-03-26T23:31:12Z Apollo 12 Mission urn:nasa:pds:context:investigation:mission.apollo_12 document_to_investigation The Apollo 12 Lunar Surface Experiments Package Host urn:nasa:pds:context:instrument_host:spacecraft.a12a is_instrument_host Apollo 12 Lunar Surface Experiments Package Solar Wind Spectrometer Instrument urn:nasa:pds:context:instrument:sws.a12a is_instrument Moon Satellite urn:nasa:pds:context:target:satellite.earth.moon document_to_target 2008-08-12 7-Bit ASCII Text version English 1 a12_lunar_gse_coordinates.asc 7-Bit ASCII Text
