Elon Musk's SpaceX on Sunday called off the launch of Starship's 10th mission from Texas over an issue at its launch site, delaying an attempt to achieve several long-sought development milestones missed due to past tests ending in early failures.
The 70.7-meter Super Heavy booster and its 52-meter Starship upper half sat stacked on a launch mount at SpaceX's Starbase rocket facilities as it was being filled with propellant ahead of a liftoff time of 7:35 p.m. ET (2335 GMT).
But roughly 30 minutes from liftoff, SpaceX said on social media platform X it was standing down to allow time to troubleshoot an issue with ground systems.
