What time is SpaceX's Starship Flight 13 launch today? Schedule, live stream, test goals

SpaceX plans the 13th Starship flight test on July 23, 2026, at 5:45 pm CT, after a scrub on July 16 due to engine failures.

Flight 13 aims to deploy 20 Starlink V3 satellites for the first time, testing laser links and solar arrays before re-entry.

The Super Heavy booster will attempt a controlled landing in the Gulf of America, while the Starship upper stage will restart a Raptor engine in space and splash down in the Indian Ocean.

Hardware and software modifications follow Flight 12 issues: engine startup sequence updated, relight hardware improved, and booster software refined.

The Starship upper stage received propulsion upgrades after one vacuum Raptor engine shut down 40 seconds after stage separation on the previous test.
