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.
