There are many different ways to look at things, or look at them with different "eyes" 😎

Remember that rock, made up of tiny spherules, which #Perseverance saw the other sol? Here is one somewhat similar, now seen by #Curiosity:

"The two rocks right in front of us are different from anything that we have looked at before on the mission, so we are eager to know what they are."

Now, let's try and make sense out of this image captured by #Perseverance earlier tosol. The distance is about 2.5m away from the camera, just to the right of the right front wheel of the rover. What exactly is that we see here?

Spherules with holes? 😮 🧐 🤔

It's obvious something was pressed on the drill tailing cone, which is not normal. No part of the turret is supposed to touch the ground other than the abrasion and drill bits. At least up to now, this has never happened before, AFAIR.

Also, there are two different colors of tailings visible.

An alien battleship in another world.

That's not too far from reality: an alien (to Mars) spaceship drops "wheels on the ground", then moves out, and dies.

The Sands of Mars

Arthur C. Clarke wrote the novel in 1951, before space flight was a thing.

The image below is an actual image of Martian sand (regolith), captured from the ground (Cape NukSack, NW Jezero Crater).

Back in our Martian escape, we sometimes wonder about cause and effect, like in this animation showing how a rock fragment may have ended up suspended at an edge of Betty's Rock, down at Hogwallow Flats (a.k.a. The Bacon Strip) overlooking Three Forks. The end frame is the real image:

Notice how the fragment bounces in the ⅓ g of Mars 🤓

#Perseverance has now gone back to South Arm, where it had been 48 Sols ago, apparently to examine the rocks there more closely.

Continued thread

The next best thing to drilling holes into rocks and taking samples, is abrading rocks.

The previous rock #sample26 which was acquired by #Perseverance from these rocks appeared to be smaller than usual. So, maybe the rover is in for another one?

#Flight41 of #Ingenuity scouted Rocky Top, an area north of Three Forks where #Perseverance spent a considerable amount of time during the first phase of its mission, before ascending to the Jezero delta. This video shows Hogwallow Flats and Rocky Top in two sequences, the second one being a "lock-on" view which I like much.
