WATER ON AIRLESS TERRESTRIAL BODIES: LUNAR CASE STUDY
The Moon is the only of these places where we have direct geological sampling and diverse surface soil samples. Study of lunar samples provides important constraints on possible formation and preservation mechanisms of water on airless bodies. Here we report results from our continuing efforts to determine the distribution and abundances of water in lunar soils of different maturity and compositions. These results will be combined with recent experimental work on solar-wind absorption and desorption, as well as literature data on bulk soils, to understand the preservation of water into the micrometeorite-impact generated melt.
