Infrared Mapping Spectrometer

A group of researchers "lunar mineralogy mapper M3 molecules found water and hydroxyl groups in different parts of the sunlit lunar surface, but more clearly detected the presence of water at higher latitudes of the moon. Suspicion of the water molecules and hydroxyl groups emerged in the past, when analyzed data obtained during Cassini's flight of the aircraft by the moon at low altitude in 1999, but the data has not yet been published. Signs of water more strongly manifest themselves in the cold high latitudes, closer to the poles. The blue arrow points to the crater Goldschmidt, a vast area, rich in feldspar and evidence of the presence of water and hydroxyl groups.

'The data obtained with a spectrometer VIMS (Visual and Infrared Mapping Spectrometer – kartografiruyuschy spectrometer operating in the visible and infrared spectral regions) of the aircraft Cassini (Cassini) and M3 are in good agreement ", – said Roger Clark (Roger Clark), a scientist from the Department of Geological Survey in Denver, USA, and a member of both VIMS research groups and M3. 'We see the presence and the water and hydroxyl groups. While their number is not known, presumably, in the lunar soil may be present about 1.000 parts per million (ppm) of water molecules.

It comparable to what you would have collected one ton of the top layer of the lunar surface, then we could get out of it 32 ounces of water. " For additional confirmation of data, scientists turned to the mission of epoxy (Epoxi), at a time when aircraft flew past the moon in June 2009 on the way to comet Hartley 2 (Hartley 2), a meeting which is scheduled for November 2010. Spacecraft not only confirmed the data obtained by VIMS and M3, but even expanded them. 'With before measurements in a wide spectral range, and photography, made over the north pole, we were able to determine the distribution of water and hydroxyl groups as a function of temperature, N, composition and time of day '- said Jessica Sunshine (Jessica Sunshine) at the University of Maryland. Mrs Sunshine is deputy principal investigator of the study group of the spacecraft Epoxy (Epoxi) and scientists research group M3. "Our analysis clearly confirms the presence of these molecules on the lunar surface, and shows that, apparently, the surface is completely exposed to the hydration for at least a certain length of lunar day. " The discovery of water molecules and hydroxyl groups on the moon raises some new questions about the origin of 'Moon Water' and its impact on the lunar mineralogy. The answers to these questions will be the subject of study and debate for many years. Translator: Elena Dorokhov (Translation 'Gulf Stream') Source: Astrogorizont – NASA news in Russian
