Overview

• Liftoff from Starbase, Texas, is targeted for a one-hour window opening at 6:30 p.m. CDT with a SpaceX livestream scheduled before launch.
• Sunday’s attempt was called off for a liquid‑oxygen ground‑system leak and Monday’s was scrubbed for weather, with forecasters now citing a low chance of rain this evening.
• Flight objectives include deploying eight Starlink satellite simulators, relighting a Raptor engine in space, and guiding the upper stage to a controlled splashdown over the Indian Ocean.
• SpaceX will forego a tower catch of the Super Heavy booster, instead aiming for a controlled water landing in the Gulf of Mexico while testing engine‑out landing‑burn scenarios.
• Mitigations include operating a nitrogen COPV at reduced pressure and testing heat‑shield changes, following a run of upper‑stage breakups and a June ground‑test explosion; success bears on Starlink scaling and NASA’s lunar plans.
