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.

The launch from Starbase in southern Texas was called off with just 40 seconds on the clock. The clock had been held at 40 seconds due to an anvil cloud in the area that had to clear in a certain timeframe. Having failed to move far enough away from the site, SpaceX scrubbed what would have been the Starship rocket’s 10th test flight.
