WASHINGTON (Reuters) – The moon lacks the bodies of liquid water that are a hallmark of Earth but scientists said on Monday lunar water is more widespread than previously known, with water molecules trapped within mineral grains on the surface and more water perhaps hidden in ice patches residing inpermanent shadows.
While research 11 years ago indicated water was relatively widespread in small amounts on the moon, a team of scientists is now reporting the first unambiguous detection of water molecules on the lunar surface. At the same time, another team is reporting that the moon possesses roughly 15,000 square miles (40,000 square kilometers) of permanent shadows that potentially could harbor hidden pockets of water in the form of ice.
Water is a precious resource and a relatively plentiful lunar presence could prove important to future astronaut and robotic missions seeking to extract and utilize water for purposes such as a drinking supply or a fuel ingredient.
A team led by Casey Honniball of NASA’s Goddard Space Flight Center in Maryland detected molecular water on the lunar surface, trapped within natural glasses or between debris grains. Previous observations have suffered from ambiguity between water and its molecular cousin hydroxyl, but the new detection used a method that yielded unambiguous findings.
The only way for this water to survive on the sunlit lunar surfaces where it was observed was to be embedded within mineral grains, protecting it from the frigid and foreboding environment. The researchers used data from the SOFIA airborne observatory, a Boeing 747SP aircraft modified to carry a telescope.Read Morehttp://On the moon, water water everywhere and not a drop to drink (yet)
