A new 5cm diameter abrasion patch imaged with the SHERLOC WATSON camera from different distances. We can see some chipping of the target in the second image. Hopefully the fragile rock won’t cause issues if they decide to attempt to core here. The images were acquired earlier today (April 12, 2025, Sol 1473 at site 72.0). I’ve stretched the contrast a little to highlight the textures. Image Credits: NASA/JPL-Caltech.

What is it? Looks like an imprint of something
It is an imprint of the abrasion tool that grinds away the weathered surface of rocks so the chemistry of the rock can be measured with the rovers instruments
What is up with the colour
I’m assuming you’re referring to the overall image quality?
If so it’s a raw image (calibrated) Here’s an earlier image of an abrasion bit inspection that has been calibrated by the MastCam-Z team (Sol 1447)
