Japan’s now-finished lunar mission found no water ice
High resolution imaging sensors on the Japanese Selene/Kaguya lunar orbiter have failed to detect any signs of water ice in permanently shaded craters around the South Pole of the Moon.
Selene’s sensors were, however, able to able pierce the darkness to reveal details detailed deep in Shackelton crater that has been a top candidate for south polar ice as a resource for later human exploitation.
Although the Japanese spacecraft found no ice it did find a crater much deeper than other lunar craters of a similar diameter and internal temperatures that could support ice delivered by comets over billions of years.
Two unmanned NASA spacecraft have just arrived at the moon to look again for water ice, that would be a critical resource aiding future human lunar exploration.
