Caption NASA originale:"(...) The purpose for these large brushings is to create a large enough patch of treated surface area for the Miniature Thermal Emission Spectrometer to analyze. Scientists had previously conducted a brushing like this one on the rock Mazatzal but the brushed area of Route 66 looks very different from the brushed area of Mazatzal, leading scientists to think that the rocks – although both light in tone – actually have different coating types".
