Watch live views from the Kennedy Space Center’s launch pad 39A as SpaceX prepares for the first flight of the Block 5 Falcon 9 rocket. The rocket is scheduled to launch the Bangabandhu 1 communications satellite no earlier than 10 May.

United Launch Alliance’s first Vulcan Centaur rocket completed a critical test-firing of its Blue Origin-built BE-4 main engines Wednesday night, clearing one of two remaining technical hurdles before the launcher is cleared for its inaugural flight later this year.

Using a Falcon 9 booster flying for a record ninth time, SpaceX’s swift sequence of launches continued Sunday with a predawn liftoff from the Kennedy Space Center carrying another set of 60 Starlink internet satellites, the company’s third mission in 10 days.
