/s@65dBnoise That's not an abrasion. That's the mark of a Super Hero!
@Nead
Our hero is in the habit of leaving such marks all over Jezero, but I'm not sure the natives like it at all:

V Martín@65dBnoise ok, so this one gives a better 3D hint that the "clouds over the moon" part was really that hard (because of the reddish coating?) and that the abrasion circle wasn't fully round after all (the part at 4-5 o'clock, which gives a bit more info than the top view https://mastodon.social/@65dBnoise/115244607301043600, the dint is there at 1 o'clock)
@sharponlooker
That not-round section at 4-5 o'clock is the abrasion edge occluding the pit, is it not?
The way I see it is that the remaining reddish coating and clouds were not touched by the abrading bit at all; it didn't reach that deep into the rock.
At 12 o'clock the rock seems tar-black, which is very interesting.
@65dBnoise I'm sure you are right, but the features left behind and all (https://mastodon.social/@sharponlooker/115248360330515627), it feels like the abrasion must have been messy. Here's a low-res copy of @Landru79 's animation (https://bsky.app/profile/landru79.bsky.social/post/3lzgjptxvzk2w)
I'd love to see sketchfab 3D models pre- and post, maybe that will make the penny really drop 😀
@sharponlooker
Right now, all the 3D I can give you is this, but I doubt it can move the penny further down:

@65dBnoise the dark stuff is protruding right? 😉
@sharponlooker
Ha, ha! #kratrarsombergeffekten at its best/worst!
Look right at the right edge, that's unmistakably dipping, although the top is tilting away from the camera too.
We're talking about a couple mm of depth at most here, so don't expect a full 3D perception unless SHERLOC does on purpose capture images with a greater parallax for 3D.
