• The formation of molecular hydrogen from water ice in the lunar regolith by energetic charged particles
  On 9 October 2009, the Lunar Crater Observation and Sensing Satellite (LCROSS) mission impacted a spent Centaur rocket into the permanently shadowed region (PSR) within Cabeus crater and detected water vapor and ice, as well as other volatiles, in the ejecta p…

• Buried Ice Deposits in Lunar Polar Cold Traps Were Disrupted by Ballistic Sedimentation
  Abstract The NASA Artemis program will send humans to the lunar south polar region, in part to investigate the availability of water ice and other in situ resources. While trace amounts of ice have been detected at the surface of polar permanently shadowed reg…

• Micro Rover Mission for Measuring Lunar Polar Ice
  Lunar ice, present at the poles, could be a source of water for drinking and growing crops, generating oxygen for breathing, and producing propellants for venturing beyond the moon to deep space. Viability of this grand vision depends on specifics of the acces…

• Impacting Lunar Prospector in a cold trap to detect water ice
  Lunar Prospector data support the contention that water ice reservoirs exist in the permanently shaded craters near the lunar poles. Yet the question remains whether the detected hydrogen abundance is actually water ice or is hydrogen in some other form. Prese…

• Identification of lunar rock types and search for polar ice by gamma ray spectroscopy
  The ability to map the surface composition of the Moon from orbit by means of gamma ray spectroscopy has been studied with attention to the possible use of small spinstabilized spacecraft. Two types of detectors were considered, a sodium iodide scintillator an…

• Seasons of Ice: Water Ice Migration and Seasonal Transient Shadow at the Lunar Poles
  Abstract Lunar water ice can be broadly categorized as belonging to one of two populations: deep, ancient, stable deposits, and shallow, transient, recent deposits. However, a third state for lunar ice is also possible. Temporary sequestration occurs when ice …

• Analyses of Lunar Orbiter Laser Altimeter 1,064‐nm Albedo in Permanently Shadowed Regions of Polar Crater Flat Floors: Implications for Surface Water Ice Occurrence and Future In Situ Exploration
  Abstract Potential water ice concentrated within the permanently shadowed regions (PSRs) near lunar poles is both scientifically significant and of value for future explorations. However, after decades of observations, the existence and characteristics of PSR …

• Discovery of moganite in a lunar meteorite as a trace of H ₂ O ice in the Moon’s regolith
  O may still remain as ice at estimated bulk content of >0.6 weight %. This indicates the possibility of the presence of abundant available water resources underneath local sites of the host bodies within the Procellarum KREEP and South Pole Aitken terranes.
