In a welcome return to active flight vehicle testing after setbacks and facility upgrades, SpaceX made strong progress with Super Heavy Booster 19 (B19) at its Massey’s test site before returning it to Mega Bay 1 for engine installation.
The Block 3 booster, earmarked for the upcoming integrated Flight 12 paired with Ship 39, has successfully completed a rigorous pre-flight testing campaign that included multiple full cryogenic proof tests—mitigating the issues seen during the loss of its predecessor, Booster 18.
