Weird triple correlation of the day: 1. At 178m above today's sea level a water wave erosion pattern at the Khafre Pyramid. 2. At the same elevation, whale skeletons can be found in the desert at Wadi Al Hitan. 3. At that elevated ocean level, the geographic center of all land on Earth is Giza...

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.

Experiment: UV light moves sand magnitudes farther than previous assumptions allow. Albedo differences like Reiner Gamma are still actively sustained. Relates to the lunar dust detector LDEX on LADEE. "The dust environment of airless planetary bodies", Horányi, Szalay, Wang.
