The Moon Mineralogy Mapper (M3) was selected as a NASA Discovery Mission of Opportunity in early February 2005 and entered phase B in May 2005. The primary science goal is to characterize and map the lunar surface composition in the context of its geologic evolution. The primary exploration goal is to assess and map the Moon mineral resources at high spatial resolution to support planning for future, targeted missions. The M3 science instrument is a high uniformity and high precision imaging spectrometer of the pushbroom type operating in the solar reflected energy portion of the electromagnetic spectrum. M3 is planned to be launched as a guest instrument on the Chandrayaan-1 mission of the Indian Space Research Organization (ISRO) in early 2008. As a guest instrument, M3 was required to be low mass, low volume and low power. Yet, the imaging spectroscopy science required a broad spectral range, excellent radiometric precision and unmatched uniformity. The complete M3 instrument measures the spectral range from 430 to 3000 nm at 10 nm sampling, with a 24-degree cross-track field-of-view and 0.7 milliradian sampling as well as greater than 90% spectral cross-track uniformity and 90% spectral IFOV uniformity. The mass and power of the M3 instrument are 8.3 kilograms and 16 Watts average. The volume of the optical and detector assembly is 25 X 18 X 12 centimeters. The M3 instrument preship review was successfully completed on the 3rd of May 2007. In this paper, the M3 characteristics and initial laboratory calibration results are presented.
