WASHINGTON—SpaceX on Monday called off its eighth Starship test flight from Texas over an unspecified issue on the rocket system’s core, delaying for at least 24 hours the company’s attempt to deploy mock Starlink satellites in space for the first time.
The test mission would have been the first Starship launch since a January mission ended eight minutes into flight when Starship, atop a rocket booster, exploded over the Caribbean, sending fiery debris streaking over the Turks and Caicos Islands and prompting a federal probe.
