scientists confirm water on the moon

scientists confirm water on the moonfrom Analysis of the lunar surface by three different spacecraft has provided “unambiguous evidence” of water on the Moon, reports. India’s Chandrayaan-1, NASA’s Cassini spacecraft, and the agency’s Deep Impact probe have all detected the presence of either water or hydroxyl – one hydrogen atom and one oxygen atom linked by a single bond. The NASA-built Moon Mineralogy Mapper (M3) aboard Chandrayaan-1 “detected wavelengths of light reflected off the surface that indicated the chemical bond between hydrogen and oxygen”. The M3 suggested water/hydroxyl in the top few millimetres of the lunar surface – the limit of its penetrative capability – and detected a water signal which “got stronger toward the polar regions”. Cassini passed by the Moon in 1999, en route to Saturn, and also noted a globally-distributed water/hydroxyl signal, once again stronger towards the poles.
