Overview

• SpaceX halted the countdown at Starbase to address a ground systems problem, and no new launch date has been provided.
• The attempt had been scheduled for 01:30 Italian time on 25 August, and a planned briefing with Elon Musk was canceled.
• The flight profile called for the Super Heavy booster to splash down in the Gulf of Mexico and for the upper stage to complete a suborbital flight before a controlled splashdown.
• Test objectives included deploying eight Starlink simulators, relighting a single Raptor on the ship, and evaluating a two‑engine landing burn for the booster.
• Regulators cleared the effort after investigations into a May in‑flight loss and a June test‑stand explosion, as Starship remains slated for NASA’s Artemis 3 lunar landing in 2027.
