Remote Views of the Moon: Past, Present, and Future

Cohen J. L. Pieters C. M. Compositional Diversity at Copernicus: Analysis of Integrated Data Using GIS [#1034] Using a GIS database, we have evaluated the distribution of olivine, anorthosite, and norite across Copernicus. High-Ca pyroxene appears to exist only in the pooled impact melt, while no pyroxene is present in the olivine- rich central peaks.

Pieters C. M. Stankevich D. G. Shkuratov Yu. G. Taylor L. A. Statistical Analysis of Lunar Mare Soil Mineralogy, Chemistry, and Reflectance Spectra [#1783] The ability of visible-near IR spectroscopy to predict composition is assessed using statistical analysis of LSCC data for mare soils. Links are made between measured elemental composition, mineralogy and visible-near IR spectroscopy using PCA.

Blewett D. T. Lucey P. G. Hawke B. R. Giguere T. A. Holtzmann J. A Comparison of Clementine UVVIS Spectral Parameters with Telescopic NIR Band Parameters [#1169] To evaluate the ability of low spectral resolution Clementine UVVIS data to characterize the shape of the 1 micron ferrous absorption band, we compare Clementine spectral parameters with band parameters derived from high spectral resolution telescopic near-IR observations.

Gillis J. J. Jolliff B. L. Bimodal TiO2 Contents of Mare Basalts at Apollo and Luna Sites and Implications for TiO2 Derived from Clementine Spectral Reflectance [#2164] A revised algorithm to estimate Ti contents of mare regions centered on Apollo and Luna sites shows a bimodal distribution, consistent with mare-basalt sample data. A global TiO2 map shows abundant intermediate TiO2 basalts in western Procellarum.

Kreslavsky M. A. Shkuratov Yu. G. Anomalies of the Lunar Regolith Structure in the Vicinity of Apollo-15 Landing Site: Results from Photometric Analysis of Clementine UVVIS Images [#1075] Analysis of a series of frames showed anomalies of the phase dependence of brightness. They are not related to albedo and are caused by anomalies in the small-scale regolith structure. They are associated with some fresh craters and the landing site.

Bussey D. B. J. Robinson M. S. Edwards K. Cook T. C. Watters T. R. Simulation of Illumination Conditions at the Lunar South Pole [#1907] Illumination simulations corresponding to Lunar Orbiter and Clementine images indicate that the available topography data are good. Simulations permit the determination of seasonal lighting variations at the lunar poles.

Rosiek M. R. Aeschliman R. Lunar Shaded Relief Map Updated with Clementine Data [#1943] Lunar maps at 1:10,000,000 scale will show elevation in false color superimposed on the shaded relief airbrush base. This series will consist of three map sheets, each portraying two opposite hemispheres.

Gaddis L. R. Sucharski T. Becker T. Gitlin A. Cartographic Processing of Digital Lunar Orbiter Data [#1892] We have completed work for a pilot project demonstrating our capabilities for high-resolution digitization and cartographic processing of five full Lunar Orbiter (LO) IV frames.

Isbell C. E. Eliason E. M. Lee E. M. McEwen A. S. Clementine: Reduced Resolution Digital Image Model of the Moon [#2076] A reduced resolution Digital Image Model (DIM) of the Moon is described. This DIM is derived from the existing Clemetine UVVIS 5-band full resolution DIM. The new DIM is a global dataset presented at 0.5, 2.5, and 12.5 km/pixel resolutions.

Johnson J. R. Maurice S. Feldman W. Lawrence D. Lucey P. Swindle T. Hydrogen Distribution from Lunar Prospector Epithermal Neutron Data: Correlations with Impact Craters and Landing Site Samples [#1440] Lunar Prospector epithermal neutron counts correlate with maturity-normalized H contents of lunar soils and with Copernican crater ages. The latter suggests the youngest ejecta have the lowest [H] due to relative lack of exposure to the solar wind.

Chevrel S. D. Pinet P. C. Daydou Y. Lawrence D. J. Feldman W. C. Maurice S. Lucey P. G. Comparison Between Spectral Clementine and Gamma-Ray Lunar Prospector Iron Abundances on the Moon [#1594] An important result from this comparison is that Lunar Prospector shows lower iron abundances in the South Pole-Aitken region than Clementine, indicating that lower crust rather than mantle would have been excavated in the impact forming the basin.

Földi T. Bérczi Sz. The Source of Water Molecules in the Vicinity of the Moon [#1148] Two continuous sources of lunar water molecules were suggested: terrestrial (+solar) hydrogen, reaching Moon in periodical lunar crossings of the Earth’s mangetic tail; and solar wind protons, recombined to atomic H, reducing oxides of surface rocks.

Genetay I. Maurice S. d’Uston C. Elphic R. C. Feldman W. C. Gasnault O. Lawrence D. J. Lunar Prospector Integrated Neutrons Below 500keV [#1755] Lunar Prospector integrated neutron flux below 500keV reinforces and complements the previous results obtained with thermal, epithermal and fast data sets.

Gasnault O. Feldman W. C. Maurice S. Genetay I. d’Uston C. The First Lunar Map of the Average Soil Atomic Mass [#1963] Indexes of lunar surface composition were obtained using neutrons spectrometers. We established a strong relationship between fast neutron fluxes and the average soil atomic mass . We inverted this relation to produce the first lunar map of .

Elphic R. C. Feldman W. C. Lawrence D. J. Gasnault O. M. Maurice S. Little R. Prettyman T. H. Binder A. B. The Lunar Neutron Leakage Flux and Its Measurement by Lunar Prospector Neutron Spectrometers [#1489] We compare calculated neutron leakage flux from the lunar surface to measured values, via modeled instrument response.

Gasnault O. Maurice S. d’Uston C. Feldman W. C. Stratified Composition Effects on Planetary Neutron Flux [#1978] We have demonstrated that a stratified composition in a planetary surface could change significantly the neutron leakage flux. In particular, the epithermal flux is enhanced when a layer of iron-poor materials is deposited above an iron-rich soil.

Gasnault O. Feldman W. C. d’Uston C. Lawrence D. J. Maurice S. Chevrel S. D. Pinet P. C. Elphic R. C. Genetay I. Moore K. R. Combined Analysis of Thorium and Fast Neutron Data at the Lunar Surface [#1987] Correlated variations of Th vs. fast neutrons are studied, in an attempt to provide a better understanding of the Th emplacement. Th rings around two major structures is also discussed, one of which may be a previously unrecognized impact basin. Lunar and Planetary Science XXXII (2001) sess66.pdf

Hagermann A. Tanaka S. Yoshida S. Hayakawa M. Fujimura A. Mizutani H. Thermal in Situ Measurements in the Lunar Regolith Using the LUNAR-A Penetrators: An Outline of Data Reduction Methods [#1497] For determining the lunar heat flow two parameters need to be measured: The thermal gradient and the thermal conductivity of the regolith. Methods for inferring these quantities from in situ measurements using the LUNAR-A penetrators will be presented.

Yoshida S. Tanaka S. Hagermann A. Hayakawa M. Fujimura A. Mizutani H. Derivation of Globally Averaged Lunar Heat Flow from the Local Heat Flow Values and the Thorium Distribution at the Surface: Expected Improvement by the LUNAR-A Mission [#1571] The relationship between the Th abundance and the heat flow data of the Apollo sites and the LUANR-A sites, where the Th concentrations are in the wide range from 1 ppm to 6 ppm, will allow for a more precise estimation of the averaged heat flow value.
