A SpaceX Falcon 9 booster designated B1067 completed its 35th mission this week, reaching the milestone just five years after its inaugural flight. The first stage launched 29 Starlink satellites from Florida and landed safely on the drone ship A Shortfall of Gravitas in the Atlantic Ocean, maintaining its position as the fleet leader.

Originally debuting in 2019 to carry a Cargo Dragon to the International Space Station, B1067 initially flew astronaut missions and commercial payloads. Since then, the booster has primarily supported Starlink deployments, with refurbishment cycles enabling rapid turnaround. Some missions launched twice within a single month, demonstrating remarkable operational tempo.

The achievement brings SpaceX closer to its stated objective of qualifying Falcon 9 first stages for 40 missions each—a goal established over two years ago. With B1067 now approaching the space shuttle Discovery's record of 39 flights across decades, the milestone highlights the rocket's exceptional reusability. These frequent flights have become routine, occurring several times weekly across the Starlink constellation.

Despite their commonplace nature, these launches remain fundamental to SpaceX's business model and valuation. As the company pursues its long-anticipated IPO, the Falcon 9's proven track record of rapid reuse and cost efficiency represents the core asset driving investor interest. The booster's performance validates years of engineering investment in reusable rocket technology.
