SpaceX just cannot catch a break! Last night, during the same cryogenic proof test that killed the previous two prototypes, SpaceX’s SN3 prototype experienced a structural failure. On-site video footage provided by famed NASASpaceFlight member BocaChicaGal shows the SN3 experiencing what appears to be a leak, followed by the fuselage collapsing.
For almost a year now, SpaceX has been building a series of Starship prototypes that will test how the system fares when launched to orbit. Coming on the heels of successful hop tests with the Starship Hopper, these tests will validate the spacecraft and its Raptor engines in space. Unfortunately, the company has encountered some hiccups with these prototypes, where the first two exploded during pressure testing.
The first prototype, Starship Mk.1, exploded on the launchpad on November 20th, 2019, during a cryogenic loading test that sent its nose cone flying. The second prototype, SN1, also exploded during a pressure test on the evening of Feb. 28th, 2020, causing the fuselage to jump several meters in the air before hitting the ground and exploding again. Undeterred, Musk recently shared images of the components for the SN3 prototype undergoing assembly.
