Live coverage: Falcon 9 rocket conducts static fire test

Liftoff from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida happened Monday at 8:35 a.m. EDT (1235 UTC), after four earlier attempts were scrubbed.

Flight controllers at NASA’s mission control center in Houston have completed the robotic swap out of a failed power distribution unit outside the International Space Station, clearing a hurdle ahead of Friday’s predawn launch from Cape Canaveral of a SpaceX supply ship.

SpaceX test-fired 27 main engines on a Falcon Heavy rocket Thursday in Florida, clearing a hurdle before installing three commercial communications satellites on the launcher for a mission to geostationary orbit later this month.
