A fully-integrated Starship-Super Heavy rocket stands ready at Pad 2 at Starbase for its second launch attempt of the Starship Flight 13 mission. SpaceX successfully stacked Ship 40 atop Booster 20 on July 22, 2026, but weather conditions have necessitated a delay.
Launch Rescheduled
As of July 23, 2026, at 4:10 p.m. EDT, SpaceX has postponed the launch due to adverse weather, now targeting a new window on July 24. The launch window will open at 5:45 p.m. CDT (6:45 p.m. EDT / 2245 UTC). This mission follows extensive work on the Raptor engines of the Super Heavy booster after an abort during a previous attempt on July 16.
Engine Modifications and Testing
Telemetry data from the aborted launch indicated that four engines failed to ignite. In response, SpaceX de-stacked Ship 40 from Booster 20 on July 17 and returned both to the production site for necessary repairs. Elon Musk confirmed that at least two Raptor engines required removal due to the hard engine stop.
After a week of modifications, Booster 20 returned to Pad 2 on July 21, where it underwent additional testing with liquid oxygen and liquid methane. SpaceX announced that preflight testing on the Super Heavy was complete, and preparations for launch were underway, although weather remained a critical concern.
Mission Objectives
The primary goal of the Starship Flight 13 mission is to deploy 20 Starlink V3 satellites from Ship 40. This deployment marks the first use of production satellites, as previous missions utilized simulators. The satellites are expected to extend solar arrays and antennas, attempting to connect with the larger Starlink constellation via high-capacity lasers. They will follow a suborbital trajectory and are anticipated to demise upon reentry approximately 20 minutes post-deployment.
Additionally, SpaceX plans to conduct a Raptor engine relight after the satellite deployment sequence, which lasts about 11 minutes. Improvements made to the sea-level Raptor engines aim to enhance reliability during the boostback burn, which is crucial for a successful splashdown in the Gulf of Mexico.
Future Implications
SpaceX’s ongoing modifications to the Super Heavy booster include hardware updates to improve engine relight reliability and adjustments to the startup sequence to prevent issues encountered during the previous flight. These enhancements are vital for the upcoming Artemis 3 mission, which will involve a docking between Starship and NASA’s Orion spacecraft.
Despite significant advancements, a recent report from the Government Accountability Office (GAO) highlights that SpaceX is over a year behind its original schedule for key events related to the Human Landing System version of Starship. The report identifies the development of the Raptor engines as a top risk, emphasizing the need for continued improvements to ensure successful future missions.
