Live coverage: Falcon 9 disintegrates after launch

SpaceX launched 57 Starlink broadband satellites and a pair of Earth observation smallsats for BlackSky on top of a Falcon 9 rocket at 1:12 a.m. EDT (0512 GMT) Friday. The 90th launch of a Falcon 9 rocket took off from pad 39A at NASA’s Kennedy Space Center in Florida.

The launch of the first batch of new-generation Iridium communications satellites Saturday marked the beginning of the end for the predictable, spectacular flares of reflected sunlight produced by the old-design craft, a favorite of amateur skywatchers for nearly two decades.

The mission came as SpaceX is preparing to launch a Dragon spacecraft to the International Space Station later this week. Liftoff of the Starlink 7-16 mission happened at 7:28 p.m. PT (10:28 p.m. ET, 0228 UTC).
