Daisy Found on “Route 66”

This panoramic camera composite image is an approximate true-color rendering of the brush-mosaic on the rock “Route 66.”   NASA’s Mars Exploration Rover Spirit used the rock abrasion tool to complete this 6-position “RAT Daisy” on sol 99 and then imaged the location on sol 100.  

The purpose for these large brushings is to create a larger surface area for the mini thermal emission spectrometer to analyze.  Scientists had previously conducted a brushing like this one on the rock “Mazatzal,” that resulted in very interesting findings.  They wanted to re-create the experiment to confirm what they found at Mazatzal.  However, the brushed area of Route 66 looks very different from Mazatzal leading scientists to think that the rocks – although both light in tone – actually have different coating types.   

This color composite was created with the L5 (535 nanometers), L6 (482 nanometers) and L7 (432 nanometers) filters.
