Improved Modeling of Lunar Prospector Neutron Spectrometer Data: Implications for Hydrogen Content at Lunar Poles
Introduction: In recent years, a number of studies [1,2,3] have been published using data from the Lunar Prospector Neutron Spectrometer (LP-NS) to identify and quantify anomalously high hydrogen abundances near the poles of the Moon, which may be in the form of water ice. If water ice is indeed present at the lunar poles in high enough abundance, this could provide a critical resource for futu...
متن کاملEarthshine at the Lunar Poles and Volatile Stability
Introduction: In the context of resumed lunar exploration , the existence of water ice at the lunar poles has become a pressing question. In support of human return to the moon, the confirmation of the water ice signature detected from orbiting spacecraft [1,2] is a high-priority task that can only be accomplished in situ. Therefore, a landed mission to the permanently shadowed lunar polar crat...
متن کاملDesign of the Scarab Rover for Mobility & Drilling in the Lunar Cold Traps
Scarab is a demonstration of a lunar rover design to explore polar cold traps for water ice as a potential resource. The envisioned mission scenario lands the rover on the floor of a permanently shadowed crater. The radioisotope powered rover then traverses kilometers in darkness, stopping to drill into the near subsurface and take data. The vehicle design employs a passive kinematic suspension...
متن کاملTopography of the lunar poles from radar interferometry: a survey of cold trap locations.
Detailed topographic maps of the lunar poles have been obtained by Earth-based radar interferometry with the 3.5-centimeter wavelength Goldstone Solar System Radar. The interferometer provided maps 300 kilometers by 1000 kilometers of both polar regions at 150-meter spatial resolution and 50-meter height resolution. Using ray tracing, these digital elevation models were used to locate regions t...
متن کاملFluxes of fast and epithermal neutrons from Lunar Prospector: evidence for water ice at the lunar poles.
Maps of epithermal- and fast-neutron fluxes measured by Lunar Prospector were used to search for deposits enriched in hydrogen at both lunar poles. Depressions in epithermal fluxes were observed close to permanently shaded areas at both poles. The peak depression at the North Pole is 4.6 percent below the average epithermal flux intensity at lower latitudes, and that at the South Pole is 3.0 pe...
