SpaceX Sets Falcon 9 Reuse Record at 33 Flights
SpaceX has set a new rocket reuse record, with its B1067 Falcon 9 booster completing the 33rd flight of a single orbital-class rocket. The launch was part of a mission to deploy Starlink satellites. This operational cadence is supported by continuous refinement of flight software, modular avionics, and autonomous navigation systems.
- Prior to its record-setting 33rd flight, booster B1067's flight history included two astronaut missions, two cargo resupply missions to the International Space Station, and numerous Starlink satellite deployments. - The Block 5 variant of the Falcon 9 was designed for at least 10 flights with minimal inspections and up to 100 flights with refurbishment, incorporating upgrades like a reusable heat shield at the base and titanium grid fins for better control during atmospheric reentry. - The Octaweb structure of the nine Merlin 1D engines on the first stage provides engine-out capability, allowing the rocket to suffer the loss of up to two engines during flight and still successfully complete its mission. - For landings at sea, the booster targets an Autonomous Spaceport Drone Ship (ASDS) which uses GPS and azimuth thrusters to maintain its position within approximately 3 meters, even in rough seas. - The progression of reusability has been rapid, with the first 10-flight booster (B1051) milestone reached in 2021, the first 20-flight booster (B1062) in 2024, and the first 30-flight booster (B1067) in 2025. - Reusability has driven the per-kilogram launch cost to Low Earth Orbit down to between $2,700 and $3,000, a significant reduction from the more than $10,000 per kilogram typical of traditional expendable launch vehicles. - The first successful controlled landing of a Falcon 9 first stage occurred in December 2015, while the first successful landing on a drone ship at sea was achieved in April 2016.
