A pebble observed from very close, and a wild guess on where it might be perched.

Every little pit and cavity on that surface is coated with that purple-sh color, which is, most probably, «a variable mixture of dust, fine regolith, sulfates, and ferric oxides cemented during past water interaction»

Last night, NASA's Perseverance rover looked up at the night sky once more, to capture interstellar comet 3I/Atlas flying by the red planet.

The distance was "only" 0.2 AU or 30 Mio km, far closer than the comet ever got to Earth.

Looks like #Perseverance found itself a new target at a new (old) location. It appears it has captured some 'flats' for the SUPERCAM, using the sky at a 76° elevation in the early local evening. Maybe to be used with SC imagery of the passing by interstellar comet 3I/Atlas?

I think Perseverance may have spotted interstellar comet 3I/Atlas last night from Mars!

After stacking 20 images from Mastcam-Z, I found a faint smudge of light in the constellation Corona Borealis close to the location where the comet was expected. 🔭

This photo from the Perseverance rover captured in early March, may be my favorite Mars image from this year.

It shows Mars' smaller moon Deimos over the hills of the Nili Planum region in the dark skies before dawn. 🔭

Last night, NASA's Perseverance rover attempted to photograph the interstellar comet 3I/Atlas from the surface of Mars.

A first look at the image sequence shows some stars in the constellation Hercules where 3I/Atlas is currently located.

#Perseverence, apparently an early riser, came back to the same spot it was two weeks ago and is eyeing that same rock, once again.

A final 3D look at the last abrasion.

#Perseverance has since moved back to where it was on Sol 1622, RMC 79.0328. The new RMC is 79.0732.

Maybe some of those veined rocks there were worth revisiting?

@65dBnoise That's not an abrasion. That's the mark of a Super Hero!

Our hero is in the habit of leaving such marks all over Jezero, but I'm not sure the natives like it at all:

@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)
Show thread65dBnoiseSep 24

@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 😀

Right now, all the 3D I can give you is this, but I doubt it can move the penny further down:

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.
