Hello from the VATT (cloudy, unfortunately). The problem with mineral
identification is that the spectrometer is not able to do very high
surface resolution spectra. I think this is related to the loss of one or
two of the reaction wheels, so they are limited to more global spectra and
thus mineral
Hello fellow meteorite (and asteroid) aficionados,

There is now a very close up high resolution of the bright spots in one
of the craters. Why are we still
in the dark as to the composition of the bright material? Does NASA
have a spectrometer on the craft. If so why can't they determine what
the white substance is composed of. If they do not h
