Those tiny sand dunes on Mars in front of the half meter diameter wheels are actually moved around today by the local wind with being heaped up from fine dust. But the larger ones next to them are permanent and have a hardened surface the rover sometimes breaks through. 📷 areo.info/mars20/ecams...

The sticky soil which glued like wet clay on the wheel inside and outside earlier this week on day 1688 may now be analyzed as I see they checked at least the ground in front of the rover. Unusual extremely black small grains can be seen in the 5cm diameter ground area areo.info/mars20/ecams...

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...

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.
