Wow, the Perseverance landing site is strewn with small spherical concretion-like objects of nearly

equal size...
So-called "Blueberries" ????
If so, are they of biological origin?
I hope we find out...
On edit, they look to be roughly equidistant from each other. Odd distribution (not random).

Perseverance is in an impact crater, after all.
How about this:
Meteor hits Mars. Meteor impact generates sufficient heat to melt igneous rock. Little globules of liquid rock are blasted into the atmosphere. Said globules solidify and freeze nearly instantly, and then they fall to the ground in an almost-perfectly-dispersed raindrop pattern.
Mystery solved ... maybe?

We have food, bottled water, and internet access. We’re gonna make it. It may take some time to get running water restored (tons of water line and water main breaks across the state), but we’re not locked in by the snow, so I think we’ll be OK so long as we keep electricity.
Thanks for asking.

We were all very worried about you, and also our other Texas DU family.

Yes, it's an impact crater - that created a body of water - a subaquous sedimentary environment.
The impact debris would be located at the bottom of the stratigraphic column, not the top - even if eroded by wind after the water body evaporated.
I also would expect that the original impact debris would be concentrated in crevices and low places - a clumped distribution, not in a more uniform manner.
In situ precipitation of concretions could be produced by abiotic or biotic processes may be a better hypothesis
