Water On The Moon

While probes and orbiters search the far-flung corners of the solar system for water, one spacecraft holds evidence that it could be hiding right in our backyard—on the moon. Data from NASA’s Lunar Reconnaissance Orbiter (LRO) suggest that water ice lies frozen near the surface at the moon’s cold, dark poles. LRO looks for water using its Lunar Explorer Neutron Detector (LEND) instrument, which detects the presence of hydrogen atoms by counting neutrons released from the moon’s soils. The measurements allow scientists to create maps that show areas of the moon that are rich in hydrogen, the main ingredient of water. Since LRO’s launch in 2009, the mission has identified likely deposits of water ice in a handful of craters on the moon’s south pole, including shadowy regions that have gone without sunlight for millions or even billions of years.
