SpaceX has completed a key test necessary for development of its next Starship prototype – stress testing a fuel tank to the point of failure, at its Starship development site in Boca Chica, Texas. This test comes on the heels of a less intense pressure test for the same tank, which resulted in a burst weld that was subsequently corrected, paving the way for the good test on Tuesday evening.

SpaceX is working on its third prototype of the Starship spacecraft at its Texas facility, which is designed to be used for high-altitude and orbital testing. SpaceX CEO Elon Musk has said that we can likely expect this version of Starship, which is dubbed ‘SN1,’ to be complete and ready for testing sometime around June based on the current development schedule.
