Water ice is thought to be trapped in large permanently shadowed regions in the Moon’s polar regions, due to their extremely low temperatures. Here, we show that many unmapped cold traps exist on small spatial scales, substantially augmenting the areas where ice may accumulate. Using theoretical models and data from the Lunar Reconnaissance Orbiter, we estimate the contribution of shadows on scales from 1 km to 1 cm, the smallest distance over which we find cold-trapping to be effective for… 
Carbon Dioxide Cold Traps on the Moon
Water ice is expected to be trapped in permanently cold regions near the lunar poles. Other ices (“super‐volatiles”) are trapped at lower temperatures, close to the lowest temperatures measured
Accessibility Data Set for Large Permanent Cold Traps at the Lunar Poles
Many large cold traps exist at both lunar poles where temperatures never exceed 110 K annually, allowing the preservation of water ice. Much has been learned about these regions from orbital
Framework for Coordinated Efforts in the Exploration of Volatiles in the South Polar Region of the Moon
The exploration of the lunar south polar region and the ground truthing of polar volatiles is one of the top priorities for several space agencies and private partners. Here we use Moon Mineralogy
Water Group Exospheres and Surface Interactions on the Moon, Mercury, and Ceres
Water ice, abundant in the outer solar system, is volatile in the inner solar system. On the largest airless bodies of the inner solar system (Mercury, the Moon, Ceres), water can be an exospheric
Temperatures Near the Lunar Poles and Their Correlation With Hydrogen Predicted by LEND
The lunar polar regions offer permanently shadowed regions (PSRs) representing the only regions which are cold enough for water ice to accumulate on the surface. The Lunar Exploration Neutron
Stratigraphy of Ice and Ejecta Deposits at the Lunar Poles
Water ice has been delivered to the lunar poles from different sources over billions of years, but this accumulation was punctuated by large impacts that excavated dry regolith from depth and
Analyzing Surface Ruggedness Inside and Outside of Ice Stability Zones at the Lunar Poles
We measured surface ruggedness within 12 polar craters on the Moon, six at each pole, using a variation of the Vector Ruggedness Measure (VRM*). We compare VRM* values derived within ice stability
Implications of surface roughness in models of water desorption on the Moon
The observed presence of water molecules in the dayside lunar regolith was an unexpected discovery and remains poorly understood. Standard thermophysical models predict temperatures that are too
Hiding in plain sight: observing objects in low lunar orbit and the L2 dark cone from a lunar surface observatory
While a high-performance sensor at EML-1 could surveil the key orbital trajectories in Earth-Moon space, Low Lunar Orbit (LLO) would remain a challenging subdomain in which to identify unknown


Thick ice deposits in shallow simple craters on the Moon and Mercury
Permanently shadowed regions near the poles of Mercury and the Moon may cold-trap water ice for geologic time periods. In past studies, thick ice deposits have been detected on Mercury, but not on
Thermal stability of ice on Ceres with rough topography
The dwarf planet Ceres may have an ice‐rich crust, and subsurface ice exposed by impacts or endogenic activity would be subject to sublimation. We model surface and subsurface temperatures on Ceres
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.
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
Seasonal Polar Temperatures on the Moon
The Diviner Lunar Radiometer Experiment on the Lunar Reconnaissance Orbiter has been acquiring visible and infrared radiance measurements of the Moon for nearly 10 years. These data have been
Subsurface ice on Mars with rough topography
High-latitude ground ice on Mars discovered by the Gamma Ray Spectrometer suite is thought to be thermally stable owing to the presence of vapor in the Martian atmosphere. However, local slopes can
Near-Surface Temperatures on Mercury and the Moon and the Stability of Polar Ice Deposits☆
Abstract In order to assess the thermal stability of polar ice deposits, we present model calculated temperatures of flat surfaces and surfaces within bowl-shaped and flat-floored polar impact
The Young Age of the LAMP‐observed Frost in Lunar Polar Cold Traps
The Lunar Reconnaissance Orbiter/Lyman Alpha Mapping Project (LAMP) ultraviolet instrument detected a 0.5–2% icy regolith mix on the floor of some of the southern pole permanently shadowed craters of
