Part of the appeal of MRO images to me is just their amazing resolution. If you had a little house on the edge of this crater you could see it this picture, which is fairly impressive considering this is another planet.

I think Perseverance rover tried to abrade the rock floor but it didn't go well. Not surprised, the rock is clearly riddled with Mars rock worm Sol 1989 (24th September, 2026) SHERLOC_WATSON cam S/D: 91/970 CC BY-NC-SA 4.0 Credits: NASA/JPL-Caltech/MSSS/Martian-Observer

A close look at the rock floor which bears straight line dents across its surface left by the skittering abrasion tool cutting through the dust into the rock beneath. Some of the more eroded rock has many small holes in it, like worm-ridden wood.

A big part of the paper (and my career) is comparative planetology, the comparing of one world with another. So in this paper, we talk about how and when the crusts of these worlds developed. Those of Mars, Mercury, and the Moon are ancient; some of Earth is very recent. And Venus?? who tf knows

Crustal growth rates of the inner Solar System bodies plotted as cumulative crustal mass as a function of time. Since Earth has two types of crust, it has two curves. Mars, Mercury, and the Moon had the bulk of their crusts in place very early on. Some of Earth's continental crust is very old, but much of it isn't. The Venus crust might be very young, on average, maybe, somehow.

A dusty rock. The left side has lighter bits in a gray matrix. The right side is much lighter with darker mottling and is closer to the camera and mostly out of focus. In the center is a cluster of dark pebbles that are somewhat embedded in the light toned rock. The cluster (and a few similar, but smaller clusters) seems to sit in a small pocket seeming to indicate that they are more resistant to erosion than the surrounding white matrix.
