“At the end of the first orbital test flight for its 164-foot Starship, SpaceX envisions re-entry into the atmosphere at speeds approaching Mach 25 or 19, 000 miles per hour followed by hypersonic flight” https://www.govtech.com/products/orbital-spacex-starship-to-splash-down-sink-near-hawaii -- _______________________________________________ Link mailing list [email protected] https://mailman.anu.edu.au/mailman/listinfo/link
