PIA05677: "Mazatzal" Vs. "Humphrey"


“Mazatzal” Vs. “Humphrey”

Caption:

These graphs show the infrared light signatures, or spectra, of the rock dubbed "Mazatzal" before and after it was brushed clean with the Mars Exploration Rover Spirit's rock abrasion tool. The comparison reveals that the surface coating of Mazatzal is of a different mineralogical make-up than its interior. Mazatzal is also compared to the rock dubbed "Humphrey," which appears to differ mineralogically.
