SpaceX aborted the Starship flight 13 launch on Thursday, July 16, 2026, after the rocket failed to ignite all engines on the pad [1], [2].
The failure highlights the ongoing technical hurdles SpaceX faces as it attempts to refine the world's most powerful launch vehicle. Any instability in the engine ignition sequence poses a significant risk to the vehicle and the launch infrastructure at the Starbase site.
The launch attempt took place at the SpaceX Starbase facility in South Texas [1], [3]. According to reports, the mission was halted at the last second when an automatic abort was triggered [2], [3]. The system intervened because only 29 of the 33 required Raptor engines ignited [3], [4].
Elon Musk, the CEO of SpaceX, addressed the malfunction following the event. "Some of the engines didn't start," Musk said [5].
Following the abort, the company postponed the mission by at least 24 hours [1]. While some reports indicated uncertainty regarding the next attempt, the current timeline suggests a brief window for engineers to diagnose the ignition failure [1], [2].
Flight 13 is part of a series of iterative tests designed to prove the reliability of the Starship system. The Raptor engines use liquid methane, and liquid oxygen, and the precise timing of their ignition is critical for a successful liftoff. The failure of four engines to fire prevented the vehicle from reaching the necessary thrust-to-weight ratio to leave the pad [3], [4].
“Only 29 of 33 Raptor engines ignited”
This abort underscores the volatility of the Raptor engine's ignition sequence during the critical seconds before liftoff. Because SpaceX relies on an iterative 'test-and-fail' development cycle, this failure provides essential data on engine reliability. However, repeated delays at the pad can impact the broader timeline for lunar missions and deep-space exploration goals.
