Dr. Phil Metzger on Twitter: “Thanks so much to the people who sent samples and pictures/videos of the particulate falling 5-6 miles from the Starship launch pad. We have analyzed the particle sizes and shapes and got an unexpected result.”
Dr. Phil Metzger on Twitter: “Partial results on the analysis of the ejecta from the SpaceX Starship launch. The visible and infrared spectra of the fine particles that rained down on Port Isobel do not match the concrete or the Fondag that was picked up on the beach.”
Dr. Phil Metzger on Twitter: “I guess I need to do simulations to see how sand can fly 5 miles from a Starship launch. I did the analysis for NASA for Mars landings, and the size of particle that went farthest in that super-thin Martian air was pea gravel (~3 mm diameter) and it only goes 725 meters.”
