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.
