SpaceX has scrubbed an attempt to launch its 10th test flight of the Starship megarocket due to “an issue with ground systems.” The rocket system has experienced a string of explosive missteps this year.

SpaceX is now aiming to launch its Starship Flight 10 test mission on Monday (Aug. 25) at 7:30 p.m. EDT (2330 GMT) after a one-day delay.

Not surprisingly, the setback delayed plans for the 10th flight test, but on Friday, SpaceX announced a target date for the highly anticipated event: Sunday, August 24, with a launch window opening at 6:30 p.m. CT (7:30 p.m. ET).
