SpaceX has once again scrubbed the latest major flight test of its Starship rocket. The next-generation spacecraft was set to launch from SpaceX’s Starbase facility in Boca Chica, Texas, on Tuesday, but cancelled it for reasons unknown.
Starship SN15’s high-altitude flight test follows four previous attempts that all ended in massive explosions. SpaceX boss Elon Musk said previous issues with the rocket’s Raptor engines have been fixed “six ways to Sunday”, though if it fails to land cleanly there are more Starship prototypes currently under development.
Airspace clearance had been approved by the Federal Aviation Administration (FAA), road closures were in place with Cameron County, and marine hazard notices had been issued. The test was expected to take place between 12pm and 8pm local time (6pm — 2am BST) on Tuesday, however a backup launch window is also in place for Wednesday.
