The Perseverance Rover driver deserves an award for best shadow image planning :) Here's the rover head shadow looking at the sticky stuff glued inside the wheel rim it won't be able to analyze. Or can it? Day 1692 today. More images from that mission day: areo.info/mars20/ecams...

A 2nd instance of the rectifier relief may exists as in the 1992 book by Peter Krassa, "Das Licht der Pharaonen - Hochtechnologie und elektrischer Strom im alten Ägypten", fig.27 shows this similar but not identical relief. That it is a photo of a modern reproduction can neither be excluded.

More sticky stuff today (1690). It resisted being scraped by a rock sliding around inside the wheel. This type of adhesive dirt on Mars was never seen before. I still think it is clay which can contain much water, here most likely brine, inside its nano-pores and layers. 📷https://areo.info/mars20

The soil also shows strong adhesion to the inside of the wheel where usually it would immediately fall down to the bottom. Image from the same day 1688.

Unusual sticky soil on the half meter diameter wheel of Perseverance Rover on Mars today mission day 1688. It appears to have the consistency of wet clay.

About ionizing radiation effects on humans during a trip to Mars the Mars Matters channel provides great explanations and describes the 5 different sources of radiation in space in detail. Sending a tobacco smoker without cigarettes to Mars would even decrease his cancer risk.

The ancients observed those huge electric discharges from the ionosphere with their own eyes and preserved them in rock art and petroglyphs to remember over generations. Those were most likely more intense sprites than today's.
