Overview

• SpaceX called off the uncrewed flight just minutes before liftoff at Starbase, Texas, citing a problem with ground systems.
• The vehicle was already on the pad and fueled when the scrub was announced.
• The company set a new target for an early Tuesday attempt, with further details still undisclosed.
• A planned Elon Musk briefing on the program’s status was canceled following the postponement.
• The scrubbed mission aimed to validate stage separation, a soft water landing for the Super Heavy in the Gulf of Mexico, a brief upper-stage burn, and a reentry test over the Indian Ocean for a system central to NASA’s lunar plans.
