SpaceX postpones the first launch attempt of its third-generation Starship, designated V3, after a ground system issue prevents liftoff. According to reports, the company completes preparations including fueling of the rocket booster and the Starship spacecraft and proceeds to the final moments before launch. Just before liftoff, mission teams call a scrub, indicating the problem is detected during ground operations rather than during flight hardware checks. The exact cause is described generally as a “ground system issue,” with engineers working to address it and prepare for a restart of the countdown. Multiple outlets report that the next attempt is likely soon after, with SpaceX expected to try again as early as Friday evening, pending review of the issue and confirmation that systems are ready. The scrub means the V3 rocket does not depart its launch site during this attempt, but the overall campaign timeline remains focused on a near-term relaunch once engineers clear the identified ground problem.
