## Why It Matters
B1040 played a role in SpaceX's early efforts to develop reusable rocket technology. As part of the Falcon 9 Block 4 series, it contributed to the company's goal of reducing launch costs by reusing rocket components. Its two launches—OTV-5 and SES-12—demonstrated the reliability of the Block 4 design. While not recovered for reuse, B1040 was part of SpaceX's broader strategy to advance spaceflight capabilities. Its legacy lies in the broader achievements of the Falcon 9 program, which has since enabled numerous commercial and scientific missions.
