It is amazing how much Mars resembles the bulk of the Arabian peninsula.
That’ll never fit for a desktop.
Thanks for posting!
Large image, all the way to the right, 1 inch up, 1/3 from the right on the screen is a rock that LOOKS just like a chunk of rotted plywood or rusted plate iron layers laying on the surface. Probably just some form of eroded sedimentary or shock compressed rock. ( I will not even mention the fat little origami duck rock in the middle on the other side of screen.)
Anyway, if I were picking rocks for curiosity to examine that would be the one.
