SpaceX experienced an anomaly with Falcon 9 booster B1086 during the Starlink 12-20 mission, leading to a fire post-landing and subsequent loss of the booster.
The fire was contained in the engine compartment, demonstrating the design's effectiveness in limiting damage to a single engine.
Initial investigation revealed a fuel leak in the first stage booster causing the fire; further analysis is ongoing to determine the root cause.
Following the mishap, regulatory authorities like the FAA grounded the Falcon 9 fleet temporarily for safety assessments.
NASA and SpaceX conducted evaluations to ensure safe operation for upcoming missions like Crew-10, SPHEREx, and PUNCH.
SpaceX faced another issue during the Starlink 11-4 mission when a small oxygen leak led to an upper stage problem affecting attitude control.
Despite the issue, Starlink satellites deployed correctly, but the rocket stage reentered the atmosphere over Poland in a passivation event.
Enhanced checks and safety measures were implemented by SpaceX to prevent similar incidents and maintain launch readiness.
SpaceX conducted a static fire test for the Crew-10 mission to evaluate fixes and readiness, emphasizing safety in crewed missions.
SpaceX has dealt with upper stage issues in previous missions but continues to address and mitigate risks to ensure mission success and safety.
