According to the reports, NASA's Lunar Reconnaissance Orbiter spacecraft has found water molecules moving around the dayside of the Moon, a finding that may prove beneficial as the agency plans to put astronauts back on the lunar surface.
John Keller, LRO deputy project scientist from NASA’s Goddard Space Flight Centre in Maryland said, “The study is an important step in advancing the water story on the Moon and is a result of years of accumulated data from the LRO mission.”
Scientists had hypothesised that hydrogen ions in the solar wind may be the source of most of the Moon's surface water. As a result, when the Moon passes behind the Earth and is shielded from the solar wind, the "water spigot" should essentially turn off.
The funding for this research came from NASA Goddard Space Flight Center's LRO program office, including an LRO LAMP subcontract between SwRI and PSI, and the team received additional support from a NASA Solar System Exploration Research Virtual Institute (SSERVI) cooperative agreement.
