Reusable hardware tracker
Every SpaceX first stage is a numbered serial — B1058, B1067, B1080. Each one flies, lands, and flies again. Below is the flight history of the most-flown active boosters as of May 2026, with crewed missions, NASA cargo runs, and Starlink batches all tracked on a single page per core.
The Falcon 9 first stage is the 41-meter tall lower section that does the heavy lifting from liftoff to roughly 80 km altitude. After staging it flips, relights three Merlin engines, and lands either on a droneship downrange or a coastal pad. The current Block 5 design is certified for at least 20 flights per core, and two boosters in this list have already crossed that threshold. Each serial number is its own data point on rocket reuse economics.
