How did the Vulcan rocket remain stable despite a major solid booster nozzle failure?

During the second flight of the ULA Vulcan rocket, a Northrop-Grumman solid rocket motor suffered a nozzle failure. This video examines how the vehicle successfully continued its mission, highlighting the critical role of guidance software in compensating for the anomaly during a high-stakes national security certification launch.

The Vulcan rocket's second flight aimed to secure certification for carrying national security payloads. Shortly after launch, one of the Northrop-Grumman solid rocket motors experienced a nozzle failure. Despite this significant hardware issue, the rocket maintained its trajectory.

The mission's success is attributed to the vehicle's guidance software, which effectively compensated for the booster's malfunction in real-time. This event provides a clear look at how automated systems manage unexpected hardware failures during flight, ensuring mission continuity even when critical components underperform.
