For my first #ThinSectionThursday a 50 year flashback to work on lunar rocks. This is tranquillityite from Apollo 14 sample 14310, an impact melt breccia. First discovered on the moon, it was later found on Earth in an Australian basalt in 2011. FOV 0.18mm.

It is encouraging to see the creation by NOAA of a global aerosol monitoring program that is intended to be an early warning system for geoengineering. I found solar geoengineering to be a lively and useful discussion topic in my volcanology class.

The U.S. Is Building an Early Warning System to Detect Geoengineering
Balloon launches from around the world are part of a new kind of global alarm system: One that can detect if another country tries to dim the sun.
