SpaceX reached a milestone with its latest Starlink launch, sending the satellites into orbit on its 600th flight of a flight-proven booster. The sexacentennial launch came on the second of two Falcon 9 missions that lifted off less than eight hours apart overnight from Monday to Tuesday (July 13 to July 14). The first flight, with Starlink batch 15-14, launched at 9:28 p.m. EDT (0128 GMT or 6:28 p.m. PDT local time) from Space Launch Complex 4 East at Vandenberg Space Force Base in California. The second flight, with Starlink group 10-45, followed at 5:10 a.m. EDT (0910 GMT) from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

B1093, launched from Florida, completed its 15th flight. B1080, launched from California, achieved its 28th mission. The record for a single Falcon 9 first stage's re-flight stands at 36 launches. The addition of 56 more Starlink satellites to SpaceX's megaconstellation brought the total active number of broadband internet relay units to 10,839, according to tracker Jonathan McDowell. In addition to Tuesday's launch being the 600th launch of a flight-proven Falcon 9 stage, SpaceX now stands at 83 Falcon 9 missions this year to date.
