An early Wednesday morning launch on the Space Coast marked the 500th time SpaceX has flown its workhorse Falcon 9 rocket, reusing the fleet-leading first stage booster for a record 29th time.

SpaceX launched its first Falcon 9 rocket on June 4, 2010. Since then it has gone through five major revisions, leading to the current Block 5 model that is used to launch satellites, robotic planetary missions and astronauts. The most launched U.S. rocket in history, of its 500th missions, all but five were successful.

Taking what it’s learned from the Falcon 9, SpaceX has designed its next-generation and much more powerful Starship rocket to also be fully reusable. It’s already demonstrated the ability to bring home the Starship first stage, though the vehicle still has much testing to undergo before it becomes operational.
