"Water on the Moon"

Abstract:

Hypothesized in the 1960s with the first evidence in the 1990s, the origin, quantity, and distribution of water on the Moon – and other airless bodies – is one of the most exciting questions in planetary sciences. Where did it come from? How much is there? What processes at what rates control the modern day distribution? And where *exactly* is the water? Fine-scale spatial knowledge of distribution is needed so that we can send landed missions to measure and sample for textures, elements, the presence of other volatiles, and isotopes to answer the questions above. I’ll review what is known as well as discuss ongoing work to prepare fine spatial scale maps of water and prepare for the next landed missions of exploration.
