Moon Mineralogy Mapper

It is an imaging spectrometer, and the team is led by Principal investigator Carle Pieters of Brown University, and managed by NASA's Jet Propulsion Laboratory.

[4] After suffering from several technical issues including failure of the star sensors and poor thermal shielding, Chandrayaan-1 stopped sending radio signals at 1:30 AM IST on 29 August 2009 shortly after which, the ISRO officially declared the mission over.

"The moon, in fact, has water in all sorts of places; not just locked up in minerals, but scattered throughout the broken-up surface, and, potentially, in blocks or sheets of ice at depth."

"[8] The detailed analysis of the full set of Moon Mineralogy Mapper data in 2018 has yielded multiple locations with water ice concentrations at the surface ranging from 2% to 30%, at latitudes above 70 degrees.

[9] M3 found a rock dominated by Mg-spinel with no detectable pyroxene or olivine present (<5%) occurring along the western inner ring of Moscoviense Basin (as one of several discrete areas).

Mosaic of images of the Moon taken by the Moon Mineralogy Mapper. Blue shows the signature of water, green shows the brightness of the surface as measured by reflected infra-red radiation from the sun and red shows an iron-bearing mineral called pyroxene .
These images show water in a very young lunar crater on the side of the Moon that faces away from Earth .
