Today I happened to leave Jezero crater 🙃

(mastodon.social/@sharponlook...)

A road sign deep in Sweden pointing to, among other places, Ulricehamn, namesake of one of the minor craters right outside Jezero crater on Mars.

There's a lot happening in that closeup, great color work!

But don't zoom & rotate too much, maybe you get a scare 😬

Hugely zoomed part of the photo, rotated to show a rock bit that looks like a spooky head flashing its teeth. Reminds a little of Marty Feldman in Young Frankenstein.

I forgot that animated gifs have to be movies in bluesky 🤦‍♂️, here's the full file for the first post (it's nice with an edit function on the fedi mastodon.social/@sharponlook...)

This corresponds to CBMD-a in these preliminary results to be presented at #EPSC2025:

Impact crater caused by (possibly) a piece of #PerseveranceRover cruise stage.

Concretions? Spherules? Why not both? 🙃

Edit of the linked SuperCam image. A small outcrop off the regolith "with a case of acne". What looks like concretions can in some places also be interpreted at embedded spherules.

Collage of both rocks. Striking similarities. They've been found scores of meters away but at a similar height on the rim.

If you liked the quoted cloudy panorama by @stim3on.bsky.social, there's a relevant current #Zooniverse project: www.zooniverse.org/projects/mat... with #MavenMission UV mosaics.

Not a simple task, but a good one to grasp how much activity there is in the Mars atmosphere.

#PlanetaryScience

Sample mosaic from the Zooniverse project, the Mars disk built of traverse slices with mapped UV colors. Multiple cloud formations are seen over the Tharsis region, with the dormant volcanoes showing as dark spots.

Personally, I was still a bit confused by the wavy ridge of the minor lobe, but with some color editing, it now looks to me that we are seeing part of the inner wall of a huge crater hollowing the lobe?

The whole-asteroid photo from the linked post, but rotated 180 deg, colours inverted, contrast and curves adjusted. An arrow points to the likely inner crater wall in the minor lobe. In this edit it looks shadowed, instead of slightly brighter as in the original, due to the phase angle.

I was surprised by this bit. Already during my time in Britain in the mid 1990s, a work colleague from Sunderland proudly mentioned this as fact when he heard where I came from. I think you need to talk to people in Sunderland, because there seems to be a story there 😉

Extract from page 35, where a hypothesized Sunderland origin of the red&white striped shirts is dated to 2023.

Amazing indeed!!!

Exquisite work! 👍 I took the liberty of rotating the 2nd one a bit, it gives a better sense of orientation. The detail and the lightning are great input for seeing how some of the small features that might look like the leopard spots from Cheyava, are probably impact spherules in this case.

I remembered having seen the photo years ago, maybe in the club's museum, so much raw feeling of a bygone era! But it wasn't until recently my ama saw it and recognized her dad in it, made us all really happy.

Same old photo with my grandad in the tie highlighted

Copies now received and they were 2nd edition, yay!

I'll definitely get a 3rd edition for myself if you include that classic photo of Zarra, which features my grandfather in the stands sporting a (I'm guessing red&white) striped tie 😉

B&W photo of Zarra covered in mud, sitting by the old San Mamés stands (taking a break? just been substituted?) The crowd behind seem enthused. Author unknown
