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 percent below the low-latitude average. No measurable depression in fast neutrons is seen at either pole… 

Global Distribution of Neutrons from Mars: Results from Mars Odyssey

Global distributions of thermal, epithermal, and fast neutron fluxes have been mapped during late southern summer/northern winter using the Mars Odyssey Neutron Spectrometer, and portions of the low to middle latitudes indicate subsurface deposits of chemically and/ or physically bound H2O and/or OH.

Improved modeling of Lunar Prospector neutron spectrometer data: Implications for hydrogen deposits at the lunar poles

[1] New models have been computed for the Lunar Prospector (LP) thermal and epithermal neutron counting rates using the particle transport code MCNPX. This work improves upon previous studies by

Evidence for water ice near the lunar poles

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

Enhanced hydrogen at the lunar poles: New insights from the detection of epithermal and fast neutron signatures

[1] The Lunar Prospector (LP) and Lunar Reconnaissance Orbiter (LRO) orbital neutron spectroscopy data sets represent a unique comprehensive multimission lunar resource. A rigorous statistical

A Quantitative Comparison of Lunar Orbital Neutron Data

Data from the Lunar Exploration Neutron Detector (LEND) Collimated Sensors for Epithermal Neutrons (CSETN) are used in conjunction with a model based on results from the Lunar Prospector (LP) mission

Evidence for the sequestration of hydrogen-bearing volatiles towards the Moon's southern pole-facing slopes

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 neutron

Reanalysis of Lunar Prospector neutron spectrometer observations over the lunar poles

[1] Components of the neutron energy spectrum measured by instruments on the Lunar Prospector (LP) spacecraft have been optimistically interpreted as indicating massive deposits of water ice or other

The Local-time variations of Lunar Prospector epithermal-neutron data

We assess local-time variations of epithermal-neutron count rates measured by the Lunar Prospector Neutron Spectrometer. We investigate the nature of these variations and find no evidence to support



Lunar neutron leakage fluxes as a function of composition and hydrogen content

Areas of the Moon that might have enhanced concentrations of hydrogen are discussed. The fluxes of thermal, epithermal, and fast neutrons escaping from the lunar surface were calculated for eight

Major compositional units of the moon: lunar prospector thermal and fast neutrons

There appears to be a smooth transition between the most mafic and feldspathic compositions, which correspond to low and high surface altitudes, respectively.

Redistribution of subsurface neutrons caused by ground ice on Mars

As part of an ongoing effort to understand data that will be returned by the Mars Observer Gamma Ray Spectrometer (MOGRS) experiment, we calculate neutron and gamma ray fluxes for simple models

Arecibo Radar Mapping of the Lunar Poles: A Search for Ice Deposits

The Arecibo 12.6-centimeter wavelength radar system was used to image the polar regions of the moon at a resolution of 125 meters in a search for ice deposits in areas of possible permanent shadow

Evidence for a basalt-free surface on Mercury and implications for internal heat.

Microwave and mid-infrared observations reveal that Mercury's surface contains less FeO + TiO2 and at least as much feldspar as the lunar highlands, suggesting a rock and soil composition that is devoid of basalt, the primary differentiate of terrestrial mantles.

Mercury Radar Imaging: Evidence for Polar Ice

The first unambiguous full-disk radar mapping of Mercury at 3.5-centimeter wavelength, with the Goldstone 70-meter antenna transmitting and 26 antennas of the Very Large Array receiving, has provided

The migration of volatiles on the surfaces of Mercury and the Moon

Radar observations of Mercury have provided the startling discovery of the probable existence of substantial deposits of ices in permanently shaded polar regions [Butler et al., 1993; Harmon et al.,

Mercury: Full-disk radar images and the detection and stability of ice at the North Pole

The first full-disk radar images of Mercury were obtained on August 8 and 23, 1991. These images were constructed using the Very Large Array (VLA) in Socorro, New Mexico, to receive and map radar

The behavior of volatiles on the lunar surface

Volatiles, and water in particular, have been thought to be unstable on the lunar surface because of the rapid removal of constituents of the lunar atmosphere by solar radiation, solar wind, and
