At 16:18:23 UTC the Mastcam Right has filmed the new excavation in the rock made by the Curiosity’s driller.
This drilling, named “Edinburgh”, is 1.6 centimeters wide and shows us the true color of the rock apart from the reddish layer that covers it.
Part of the excavated material will be analyzed inside the rover, expanding the mineralogical information collected in the Gale crater. It is clear that the simple observations made by the various orbiters would never be able to analyze rocks that, as in this case, are literally and totally encrusted by a reddish layer.
The original image has undergone a reduction of noise due to Jpeg compression, white balance and a slight increase in microcontrast and chromatic saturation in order to make the colors more similar to what the human eye would see.
