SpaceX is set to launch a Falcon 9 rocket from Cape Canaveral Space Force Station later today, with a payload of more Starlink satellites. The latest data shows the launch window now opens at 3:57pm and runs until 6:40pm. About 8-minutes after liftoff, the first stage booster of the Falcon 9 will return for a landing on a barge in the ocean, meaning we won’t hear any sonic booms from this one.
