Watering the Moon About a year ago, a spent upper stage of an Atlas rocket was deliberately crashed into a crater at the south pole of the Moon, ejecting a plume of debris, dust, and vapor. The goal of this event, the Lunar Crater Observation and Sensing Satellite (LCROSS) experiment, was to search for water and other volatiles in the soil of one of the coldest places on the Moon: the permanently shadowed region within the Cabeus crater. Using ultraviolet, visible, and near-infrared… 

LRO-LAMP Observations of the LCROSS Impact Plume

Watering the Moon About a year ago, a spent upper stage of an Atlas rocket was deliberately crashed into a crater at the south pole of the Moon, ejecting a plume of debris, dust, and vapor that revealed water and other volatiles expected to be trapped in lunar polar soils.

Diviner Lunar Radiometer Observations of the LCROSS Impact

Watering the Moon About a year ago, a spent upper stage of an Atlas rocket was deliberately crashed into a crater at the south pole of the Moon, ejecting a plume of debris, dust, and vapor that plunged through the lunar soil, revealing water and other volatiles.

Diviner Lunar Radiometer Observations of Cold Traps in the Moon’s South Polar Region

The diverse mixture of water and high-volatility compounds detected in the LCROSS ejecta plume is strong evidence for the impact delivery and cold-trapping of volatiles derived from primitive outer solar system bodies.

Hydrogen Mapping of the Lunar South Pole Using the LRO Neutron Detector Experiment LEND

The LCROSS impact site inside the Cabeus crater demonstrates the highest hydrogen concentration in the lunar south polar region, corresponding to an estimated content of 0.5 to 4.0% water ice by weight, depending on the thickness of any overlying dry regolith layer.

Detection of Adsorbed Water and Hydroxyl on the Moon

Space-based spectroscopic measurements provide evidence for water or hydroxyl (OH) on the surface of the Moon and imply that solar wind is depositing and/or somehow forming water and OH in minerals near the lunar surface, and that this trapped water is dynamic.

Temporal and Spatial Variability of Lunar Hydration As Observed by the Deep Impact Spacecraft

Analysis of recent infrared mapping by Chandrayaan-1 and Deep Impact and reexamining Cassini data obtained during its early flyby of the Moon reveals a noticeable absorption signal for H2O and OH across much of the surface, suggesting solar wind is depositing and/or somehow forming water and OH in minerals near the lunar surface, and that this trapped water is dynamic.

Character and Spatial Distribution of OH/H2O on the Surface of the Moon Seen by M3 on Chandrayaan-1

Analysis of recent infrared mapping by Chandrayaan-1 and Deep Impact, and reexamining Cassini data obtained during its early flyby of the Moon, Pieters et al. reveal a noticeable absorption signal for H2O and OH across much of the surface, implying that solar wind is depositing and/or somehow forming water and OH in minerals near the lunar surface, and that this trapped water is dynamic.

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, in

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
