Flaky Martian rock

Cool image time! The photo to the right, reduced and enhanced to post here, was taken on May 15, 2022 (sol 3474) by the high resolution camera on the Mars rover Curiosity, and shows a rock that was near the rover at that time that I estimate to be around three to four feet long.
This picture was taken the same day Curiosity also took a panorama and close-up images of a row of teeth-like boulders that sat a short distance in front of the rover. Those rocks, much larger than the one to the right, had numerous large flakes protruding from their sides.
This smaller rock has even more such flakes, all much smaller and clearly more delicate.
The overview map to the right shows Curiosity’s present position with the blue dot. The yellow dot marks where it was when it took this photograph. The red dotted line shows the rover’s original planned route. The white arrows indicate what the scientists have dubbed the “marker horizon,” a distinct layer found in many places on the flanks of Mount Sharp that they are very eager to study up close.
The green dot marks the approximate location of a recurring slope lineae, a place where the cliff is seasonally darkened by a streak that appears each spring and then fades.
The two orange dotted lines are my guesses for the two possible routes the rover will take from here to get back to its planned route, abandoned in mid-April when the Greenheugh Pediment was found too rough for Curiosity’s wheels. Though science team has not published a new route, the direction traveled in recent weeks suggests these are the possibilities. If I had to choose, I would favor the east route, as it bypasses more completely the pediment with its rough terrain.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

hi
Yes! If I were standing in front of that rock ( wearing a space suit, of course ) I would take
one look at that and it would scare the beJesus out of me because it would rub my nose in
the fact that I am indeed on an alien planet. So many of the Mars pictures look sort-a, kind-a
alien, but this really, really does look weird and other worldly.
I really enjoy “Cool Image Time!”
Why does the image look like it was taken through a window screen? It doesn’t appear to be pixelated.
Andi: I don’t know, but that is how the hi-res images have been appearing on the raw image page now for about a year.
I think I will ask.
