[1] The Moon Mineralogy Mapper (M 3), a high‐resolution, high‐precision imaging spectrometer, flew on board India's Chandrayaan‐1 Mission from October 2008 through August 2009. This paper describes some of the spatial sampling aspects of the instrument, the planned mission, and the mission as flown. We also outline the content and context of the resulting(More)
[1] High‐resolution compositional data from Moon Mineralogy Mapper (M 3) for the Moscoviense region on the lunar farside reveal three unusual, but distinctive, rock types along the inner basin ring. These are designated " OOS " since they are dominated by high concentrations of orthopyroxene, olivine, and Mg‐rich spinel, respectively. The OOS occur as small(More)

[1] The NASA Discovery Moon Mineralogy Mapper imaging spectrometer was selected to pursue a wide range of science objectives requiring measurement of composition at fine spatial scales over the full lunar surface. To pursue these objectives, a broad spectral range imaging spectrometer with high uniformity and high signal‐to‐noise ratio capable of measuring(More)
[1] Analysis of high resolution Moon Mineralogy Mapper (M 3) data reveals the presence of a prominent Mg‐spinel‐rich lithology in the central peaks of Theophilus crater on the lunar nearside. Other peak‐associated lithologies are comprised of plagioclase, olivine, and pyroxene‐bearing materials. A consistent spatial association of Mg‐spinel with mafic‐free(More)
Lunar olivines typically contain inclusions of Cr–spinel (chromite) that influence their measured optical properties. These altered optical properties complicate modeled predictions of olivine composition from reflectance spectra. Approaches developed for inclusion-free terrestrial olivine spectra must be modified to be applied to chromite-bearing lunar(More)

Introduction: Almost all lunar multi-ringed impact basins have been eroded by impacts or filled by mare volcanism. One multi-ringed basin, Orientale, remains largely unfilled by mare volcanism and offers substantial clues to the nature of basin forming events and their early evolution. The Orientale basin (~930 km in diameter) (Fig. 1), the youngest (~3.82(More)
Introduction: Rocks and soils are mostly an intimate mixture of component minerals. Photons of light falling onto such a target are multiply scattered and in the process interact with more than one type of mineral. The reflected photons received at the detector therefore carry information from multiple components present in the mixture, with individual(More)
The search for water on the surface of the anhydrous Moon had remained an unfulfilled quest for 40 years. However, the Moon Mineralogy Mapper (M3) on Chandrayaan-1 has recently detected absorption features near 2.8 to 3.0 micrometers on the surface of the Moon. For silicate bodies, such features are typically attributed to hydroxyl- and/or water-bearing(More)
Overview Students are ill-served when grading fails to detect errors in their solutions to programming assignments; they will assume that their development process was adequate when in fact it was not. Yet assignments even in introductory courses can be too complex to evaluate thoroughly by conventional , manual means. Some instructors have used various(More)
Introduction: Investigation of spectral anomalies in global data acquired with the Moon Mineralogy Mapper (M 3) [1] has revealed a new, unique, and unexpected spinel-rich lithology on the central nearside. These spinel-rich deposits are found only among the Sinus Aestuum pyroclastic/dark mantle deposits (DMD) and are notably absent from the adjacent Rima(More)
