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… Expand
Detection of Water in the LCROSS Ejecta Plume
TLDR
The Lunar Crater Observation and Sensing Satellite (LCROSS) mission was designed to provide direct evidence that water ice may be presented in permanently shadowed craters of the Moon, and spectral bands of a number of other volatile compounds were observed. Expand
