SPACEX'S NEXT-GEN SUPER HEAVY BOOSTER ACES FOUR DAYS OF “CRYOPROOF” TESTING

Summary from the TLDR newsletter

SpaceX's upgraded Super Heavy booster has completed cryogenic proof testing for the first time. The successful test moves engineers closer to launching the first test flight of an upgraded version of SpaceX's mega-rocket, Starship V3. SpaceX launched Starship V2 five times last year, but the first three test flights failed. SpaceX could be in position to launch the first Starship V3 test flight before the end of March.
