3 is an imaging spectrometer that operates from the visible into the near-infrared (0.42–3.0 μm) where highly diagnostic mineral absorption bands occur. Over the course of the mission M 3 will provide low resolution spectro-scopic data for the entire lunar surface at 140 m/pixel (86 spectral channels) to be used as a base-map and high spectral resolution(More)
[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)
–The lunar rock and mineral characterization consortium (LRMCC) has conducted coordinated mineralogy ⁄ petrography ⁄ spectroscopy analyses of a suite of pristine lunar basalts. Four basalt slabs (two low-Ti, two high-Ti) and paired thin sections were analyzed. Thin sections were analyzed for mineralogy ⁄ petrography, while the slabs were used to prepare(More)
We report new high-precision laser fluorination three-isotope oxygen data for lunar materials. Terrestrial silicates with a range of δ 18 O values (− 0.5 to 22.9‰) were analyzed to independently determine the slope of the terrestrial fractionation line (TFL; λ = 0.5259 ± 0.0008; 95% confidence level). This new TFL determination allows direct comparison of(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] With reflectance spectroscopy, one is measuring only properties of the fine-grained regolith most affected by space weathering. The Lunar Soil Characterization Consortium has undertaken the task of coordinated characterization of lunar soils, with respect to their mineralogical and chemical makeup. It is these lunar soils that are being used as ''ground(More)
[1] We evaluate the effect and importance of a ground truth correction for the Moon Mineralogy Mapper (M 3) level 2 (reflectance) data set. This correction is derived from extensive laboratory characterizations of mature feldspathic lunar soils and is designed to improve the accuracy of 1 mm absorption features in M 3 reflectance data. To evaluate the(More)
We have determined the abundances of 16O, 17O, and 18O in 31 lunar samples from Apollo missions 11, 12, 15, 16, and 17 using a high-precision laser fluorination technique. All oxygen isotope compositions plot within +/-0.016 per mil (2 standard deviations) on a single mass-dependent fractionation line that is identical to the terrestrial fractionation line(More)
A new combined rhenium-osmium- and platinum-group element data set for basalts from the Moon establishes that the basalts have uniformly low abundances of highly siderophile elements. The data set indicates a lunar mantle with long-term, chondritic, highly siderophile element ratios, but with absolute abundances that are over 20 times lower than those in(More)
