• Illumination conditions of the lunar polar regions using LOLA topography (2011, methodology): “Observations by Lunar Prospector (Feldman et al., 2000) corroborated the relationship between PSRs and estimated volatile abundances.”
• Mercury’s Weather-Beaten Surface: Understanding Mercury in the Context of Lunar and Asteroidal Space Weathering Studies (2014, background): “…mature, equatorial soils (Morris 1976; Crider and Vondrak 2003) and, on average, is about 100 ppm higher within the higher-latitude, colder soils (Feldman et al. 2000), which implies that a steady state is achieved between H2 release and H2 generation in mature regolith (Crider and Vondrak…”
• Evidence for water ice near the lunar poles (2001, methodology): “We presently do not understand the physical reasons for the local maxima, but the minima have been interpreted in terms of an enhanced abundance of hydrogen [Feldman et al., 1998, 2000a].”
• Improved modeling of Lunar Prospector neutron spectrometer data: Implications for hydrogen deposits at the lunar poles (2006, methodology): “The studies of Feldman et al. [1998, 2000a, 2001] used a combination of two different codes to model the neutron counting rate (see also Drake et al. [1988] and Feldman et al. [1993] for descriptions of how these codes were incorporated into planetary neutron flux models).”
• Sources and physical processes responsible for OH/H2O in the lunar soil as revealed by the Moon Mineralogy Mapper (M3) (2011, background): “It also was only weakly correlated with the Lunar Prospector neutron spectrometer hydrogen abundances [Feldman et al., 1998, 2000, 2001; Lawrence et al., 2006; Pieters et al., 2009], suggesting probably a different source mechanism and possibly a surficial process that would not have been detected…”
• Lunar Reconnaissance Orbiter Camera (LROC) Instrument Overview (2010, background): “Theory as well as radar and neutron measurements suggest that deposits of water-ice (a potentially valuable lunar resource) may occur in permanently shadowed regions near the poles (Feldman et al. 2000; Ingersoll et al. 1992; Nozette et al. 2001; Watson et al. 1961).”
• Extremely high reflection of solar wind protons as neutral hydrogen atoms from regolith in space (2009, background): “…directly with the surface, e.g. solar wind with the lunar regolith, and it has been tacitly assumed that the plasma is almost completely absorbed (o1% reflected) in the surface material (e.g. Crider and Vondrak, 2002; Schmitt et al., 2000; Feldman et al., 2000; Behrisch and Wittmaack, 1991).”
• Lunar rare earth element distribution and ramifications for FeO and TiO2: Lunar Prospector neutron spectrometer observations (2000, background): “…Cross Section, eff Simulations of neutron transport and absorption have shown that there is a monotonic relationship between a material's ability to absorb thermal neutrons and the ratio of epithermal neutron flux to thermal neutron flux [Feldman et al., 1991; see also Feldman et al., 2000a].”
