Lunar Mission Data Analysis Finds Widespread Evidence of Ice Deposits

Deposits of ice in lunar dust and rock (regolith) are more extensive than previously thought, according to a new analysis of data from NASA’s LRO (Lunar Reconnaissance Orbiter) mission. Ice would be a valuable resource for future lunar expeditions. Water could be used for radiation protection and supporting human explorers, or broken into its hydrogen and oxygen components to make rocket fuel, energy, and breathable air.

Frost on moon’s surface: New evidence

In craters near the south pole of the moon, NASA's Lunar Reconnaissance Orbiter found some bright areas and some very cold areas. In areas that are both bright and cold, water ice may be present on the surface as frost. Credit: NASA's Goddard Space Flight Center/Scientific Visualization Studio

Scientists using data from NASA’s Lunar Reconnaissance Orbiter, or LRO, have identified bright areas in craters near the moon’s south pole that are cold enough to have frost present on the surface. The new evidence comes from an analysis that combined surface temperatures with information about how much light is reflected off the moon’s surface.
 
“We found that the coldest places near the moon’s south pole are also the brightest places – brighter than we would expect from soil alone – and...
