Mastcam multispectral imaging results from the Mars Science Laboratory investigation in Yellowknife Bay

The Mars Science Laboratory (MSL) “Curiosity” rover has been investigating the visible to nearinfrared (Vis-NIR) reflectance properties of surface materials at Gale crater using science filter images from the Mastcam instrument. Within the Yellowknife Bay region, Mastcam observations reveal the greatest spectral diversity yet observed during the MSL mission. Mastcam observations of broken or brushed rock surfaces reveal blueish-gray hues, and spectra of some fracture-filling veins are consistent with the presence of hydrated minerals.
