The purpose of this workshop is to identify the impact site for the LCROSS mission with the highest potential for scientific return.

The primary objective of the LCROSS mission is to help advance the Vision for Space Exploration by investigating the presence of water on the Moon. The mission, scheduled for launch in October 2008, will use the impact of its upper stage launch vehicle to enable a monitoring spacecraft following closely behind to study the composition of lunar regolith in a permanently shadowed region where cold-trapping of volatiles is expected. The ejecta cloud will be imaged and studied in detail spectroscopically in order to directly measure the concentration of water and to characterize other physical and compositional properties of permanently shadowed lunar regolith.
