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.”Project Morpheus : HomeNASA Morpheus Lander Crash and Explosions - YouTubeFollow Dr. Phil MetzgerDr. Phil Metzger (@DrPhiltill) / TwitterPhilip Metzger – Space Mining, Space Settlement, and Space Science!Follow Off-NominalSubscribe to the show! - Off-NominalSupport the show, join the DiscordOff-Nominal (@offnom) / TwitterOff-Nominal (@offnom@spacey.space) - Spacey SpaceFollow JakeWeMartians Podcast - Follow Humanity's Journey to MarsWeMartians Podcast (@We_Martians) | TwitterJake Robins (@JakeOnOrbit) | TwitterJake Robins (@JakeOnOrbit@spacey.space) - Spacey SpaceFollow AnthonyMain Engine Cut OffMain Engine Cut Off (@WeHaveMECO) | TwitterMain Engine Cut Off (@meco@spacey.space) - Spacey SpaceAnthony Colangelo (@acolangelo) | TwitterAnthony Colangelo (@acolangelo@jawns.club) - jawns.club ?Off-Nominal MerchandiseOff-Nominal Logo TeeWeMartians Shop | MECO Shop
