THE CLEMENTINE MISSION TO THE MOON - SCIENTIFIC OVERVIEW

In the course of 71 days in lunar orbit, from 19 February to 3 May 199 4, the Clementine spacecraft acquired just under two million digital i mages of the moon at visible and infrared wavelengths. These data are enabling the global mapping of the rock types of the lunar crust and t he first detailed investigation of the geology of the lunar polar regi ons and the lunar far side. In addition, laser-ranging measurements pr ovided the first view of the global topographic figure of the moon. Th e topography of many ancient impact basins has been measured, and a gl obal map of the thickness of the lunar crust has been derived from the topography and gravity.
