SpaceX is preparing to launch a Falcon 9 rocket early Sunday morning.
Liftoff is scheduled for approximately 4:14 a.m. The mission is expected to deliver 27 Starlink satellites into low Earth orbit.
SpaceX officials say it will be the 19th flight for the first-stage booster supporting the mission. Following stage separation, the first stage is expected to land on a droneship in the Pacific Ocean.
