Improved versions of Lunar Prospector thermal and epithermal neutron data were studied to help discriminate between potential delivery and retention mechanisms for hydrogen on the Moon. Improved spatial resolution at both poles shows that the largest concentrations of hydrogen overlay regions in permanent shade. In the north these regions consist of a heavily cratered terrain containing many small (less than ∼10-km diameter), isolated craters. These border circular areas of hydrogen abundance… Expand

Models of the distribution and abundance of hydrogen at the lunar south pole
[1] Permanently shadowed locations at the lunar poles are potential sites for significant concentrations of cold-trapped volatiles, including water ice. Hydrogen enhancements are seen at the poles,Expand
No evidence for thick deposits of ice at the lunar south pole
New 20-m resolution, 13-cm-wavelength radar images are presented that show no evidence for concentrated deposits of water ice in Shackleton crater or elsewhere at the Moon's south pole, consistent with the ice being present only as disseminated grains in the lunar regolith. Expand
The Lunar Thermal Ice Pump
It has long been suggested that water ice can exist in extremely cold regions near the lunar poles, where sublimation loss is negligible. The geographic distribution of H-bearing regolith shows onlyExpand
Effects of orbital evolution on lunar ice stability
[1] Many regions near the lunar poles are currently cold enough that surface water ice would be stable against sublimation losses for billions of years. However, most of these environments areExpand
Lunar Polar Ice and the Obliquity History of the Moon
Water ice is currently stable from sublimation loss in shadowed environments near the lunar poles. However, most current temperature environments are generally too cold to allow efficient diffusiveExpand
New estimates for the sublimation rate for ice on the Moon
The strong hydrogen signal that the Lunar Prospector saw at the Moon's poles suggests that water ice may be present near the surface of the lunar regolith. A robotic mission to obtain in situ samplesExpand
Testing lunar permanently shadowed regions for water ice: LEND results from LRO
[1] We use measurements from the Lunar Exploration Neutron Detector (LEND) collimated sensors during more than one year of the mapping phase of NASA's Lunar Reconnaissance Orbiter (LRO) mission toExpand
Lunar Prospector epithermal neutrons from impact craters and landing sites: Implications for surface maturity and hydrogen distribution
[1] Initial studies of neutron spectrometer data returned by Lunar Prospector concentrated on the discovery of enhanced hydrogen abundances near both lunar poles. However, the nonpolar data exhibitExpand
Lunar true polar wander inferred from polar hydrogen
The hypothesis that true polar wander was caused by a low-density thermal anomaly beneath the Procellarum region implies that polar wander initiated billions of years ago and that a large portion of the measured polar hydrogen is ancient, recording early delivery of water to the inner Solar System.

Evolution of lunar polar ice stability
Abstract The polar regions of the Moon and Mercury both have permanently shadowed environments, potentially capable of harboring ice (cold traps). While cold traps are likely to have been stable forExpand


Polar hydrogen deposits on the Moon
Neutron and gamma-ray data measured using the Lunar Prospector spectrometers were analyzed to define the enhanced hydrogen deposits near both poles of the Moon. Combining the new low-altitude neutronExpand
Fluxes 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, and data are consistent with deposits of hydrogen in the form of water ice that are covered by as much as 40 centimeters of desiccated regolith within permanently shaded craters near both poles.

Thorium abundances on the lunar surface
Measurements of absolute thorium abundances on the lunar surface are presented using both the high- and low-altitude data taken with the Lunar Prospector Gamma-Ray Spectrometer. An analysis of theExpand

Several volatiles implanted into the lunar regolith by the solar wind are potentially important lunar resources. Lunar 3 ~ e might be mined as a fuel for terrestrial nuclear fusion reactors [I].Expand
Lunar Cold Traps: Effects of Double Shielding
Abstract This paper deals with the problem of water permanence on the surface of the Moon. Possible zones where water ice can survive are called cold traps (K. Watson, B. C. Murray, and H. BrownExpand

Ice in the lunar polar regions
The idea that ice and other trapped volatiles exist in permanently shadowed regions near the lunar poles was proposed by Watson, Murray, and Brown [1961]. It is reexamined in the present paper, inExpand

Contribution of the mantle to the lunar asymmetry
