In the course of 71 days in lunar orbit, from 19 February to 3 May 1994, the Clementine spacecraft acquired just under two million digital images of the moon at visible and infrared wavelengths. These data are enabling the global mapping of the rock types of the lunar crust and the first detailed investigation of the geology of the lunar polar regions and(More)
We have expanded on previous methods for correcting sense, the requirement of thermodynamic equilibrium in thermal infrared field measurements for atmospheric Kirchhoff ’s law is violated (Badenas, 1997). downwelling radiance (Salisbury and D’Aria, 1992; Korb Nerry et al. (1990a,b) and Labed and Stoll (1991) et al., 1996; Hook and Kahle, 1996) by comparing(More)
[1] As of June 19, 2010, the Lunar Orbiter Laser Altimeter, an instrument on the Lunar Reconnaissance Orbiter, has collected over 2.0 × 10 measurements of elevation that collectively represent the highest resolution global model of lunar topography yet produced. These altimetric observations have been used to improve the lunar geodetic grid to ∼10 m radial(More)
Combined remote laser-induced breakdown spectroscopy (LIBS) and Raman spectroscopy investigations at a distance of 8.6m have been carried out in air and under a simulated Martian atmosphere of 933Pa (7Torr) CO(2) on calcite (CaCO(3)), gypsum (CaSO(4).2H(2)O), and elemental sulfur (S), and LIBS investigations on chalcopyrite (CuFeS(2)) and pyrite (FeS(2)).(More)
Raman spectroscopy and laser-induced breakdown spectroscopy (LIBS) of solid samples have both been shown to be feasible with sample-to-instrument distances of many meters. The two techniques are very useful together, as the combination of elemental compositions from LIBS and molecular vibrational information from Raman spectroscopy strongly complement each(More)
Diviner Lunar Radiometer Experiment surface-temperature maps reveal the existence of widespread surface and near-surface cryogenic regions that extend beyond the boundaries of persistent shadow. The Lunar Crater Observation and Sensing Satellite (LCROSS) struck one of the coldest of these regions, where subsurface temperatures are estimated to be 38 kelvin.(More)
On 25 October 2000, the Near Earth Asteroid Rendevous (NEAR)-Shoemaker spacecraft executed a low-altitude flyover of asteroid 433 Eros, making it possible to image the surface at a resolution of about 1 meter per pixel. The images reveal an evolved surface distinguished by an abundance of ejecta blocks, a dearth of small craters, and smooth material(More)
From February 13 to May 13, 2000, the Near Infrared Spectrometer (NIS) instrument on the Near Earth Asteroid Rendezvous (NEAR) mission obtained more than 200,000 spatially-resolved 800 to 2500 nm reflectance spectra of the S-type asteroid 433 Eros. An important subset of the spectra were obtained during a unique opportunity on February 13 and 14, when the(More)
Introduction: Determining the global distribution of minerals on the Moon has been an important goal of lunar science [1]. Lunar mineralogy is relatively simple , being dominated by just five minerals. Tompkins and Pieters [2] showed that the major lunar minerals can be detected using data from the Clementine UVVIS camera for locations that are sufficiently(More)
