This probably deserves it's own thread. Seems the evidence is not specific to only one mission...

Interesting finding. A similar absorption band at 3.15 microns was found on Io by NIMS both at a low background level, and in small concentrations. At the time, it was suggested that water (or hydrated minerals) arrived on Io either through cometary impacts or from Io volcanic activity, but now I wonder if charged particles in Jupiter's magnetic field could do something similar on Io to what these particles in the solar wind are apparently doing on the Moon (maybe with cometary impacts to explain the local concentrations).
