SpaceX schedules Starship Flight 13 for July 16 and addresses prior launch engine sequencing error

SpaceX announced that its next Starship launch, Flight 13, is slated for no earlier than Thursday, July 16. The schedule follows two weeks of engine‑fire tests that lit all six Raptor 3 engines on the upper “Ship” stage and all 33 on the “Super Heavy” booster. Flight 13 will be the second flight of the new Version 3 (V3) configuration, which promises higher thrust and payload capacity. The mission’s primary goal is to repeat the objectives of Flight 12 while correcting the hot‑staging error that caused a 90‑degree orientation slip and a partial engine‑restart failure. Success would move SpaceX closer to a fully reusable launch system.

What happened

SpaceX posted on July 11 that the launch window opens on July 16, pending range clearance. The company completed full‑duration static fires on both stages, igniting all six Raptor 3 engines on the Ship and all 33 on Super Heavy, confirming the new hardware’s performance envelope. Flight 12, the inaugural V3 flight, suffered a 90‑degree orientation error after “hot staging” because Ship’s engines ignited before the physical separation, and five of Super Heavy’s 33 engines failed to relight, cutting the boost‑back burn short.

In response, engineers revised the startup sequence so Ship’s engines fire only after clean separation, and they installed updated hardware on Super Heavy to improve engine relight reliability. The modifications are intended to keep the booster on a trajectory that allows the “Mechazilla” tower to catch it at the launch site, rather than risking a splashdown.

Why it matters

A successful Flight 13 would demonstrate that the V3 upgrades—greater thrust, higher payload margin, and refined re‑entry architecture—are operational, clearing a path for NASA’s Artemis cargo missions and future lunar lander launches. Reliable on‑site recovery of both stages would dramatically cut launch costs, a cornerstone of SpaceX’s business model. Conversely, another failure could delay the timeline for deep‑space missions that depend on Starship’s heavy‑lift capability.

How to think about it

Treat Flight 13 as a technology‑validation milestone rather than a commercial payload launch. Follow the live telemetry to see whether the revised hot‑staging sequence holds, and watch the booster’s trajectory for signs of the intended on‑site capture. The outcome will inform how quickly SpaceX can transition Starship from a testbed to a regular launch vehicle for government and private customers.
