SpaceX's next-gen Super Heavy booster aces four days of "cryoproof" testing
Summary
SpaceX has completed cryogenic proof testing on its next-gen Super Heavy booster (V3/Block 3) at Starbase, validating redesigned propellant systems and structural strength. The test sequence used liquid nitrogen across multiple cycles, and the booster will later be equipped with 33 Raptor 3 engines and a triple-grid-fin layout with an integrated hot-staging ring, aiming for a Starship V3 test flight by March and advancing NASA Artemis-related objectives.
