Live coverage: Falcon 9 disintegrates after launch

Russian commander Oleg Kononenko, Canadian co-pilot David Saint-Jacques and NASA flight engineer Anne McClain closed out a 204-day mission in orbit Monday with an undocking from the International Space Station at 7:25 p.m. EDT (2325 GMT), followed by landing in Kazakhstan aboard their Soyuz MS-11 capsule at 10:47 p.m. EDT (0247 GMT Tuesday).

SpaceX test-fired a Falcon 9 rocket Wednesday afternoon at NASA’s Kennedy Space Center in Florida, clearing a major hurdle before it launches Saturday night — weather permitting — with a four-person crew heading for the International Space Station.

The Starlink 15-6 mission will add another 26 satellites into SpaceX’s low Earth orbit constellation. Liftoff occurred from pad 4E at 6:54 p.m. PDT (9:54 p.m. EDT, 0154 UTC).
