Two potential missions for investigation of lunar KREEP site resources are described. The objective of the first is to locate all major KREEP sites from lunar orbit at 25 km resolution. X-ray fluorescence spectroscopy will be used to observe chemical elements at the surface (cm depths) and fission neutrons for observation of stable isotopes at greater depths. The second mission involves the use of a land rover system for mapping finer details of selected KREEP sites at meter resolution. The land rover, required instruments and supporting equipment will be powered by a 100 watt thermoelectric generator with a Pu238 source. The payload of this system is estimated at 100kg. The mission objective is the location, investigation and mapping of KREEP regions rich in important industrial reagents and Whitlockite minerals rich in uranium and the rare earths. Details of tests to be performed including rapid observations at low speeds and long observation times on cored samples will be given and supporting equipment is described.
