SpaceX is preparing for its next Falcon 9 launch out of Vandenberg Space Force Base.
The launch countdown on SpaceX’s website shows the mission is set to liftoff around 9:45 p.m. Monday and deliver 21 Starlink satellites to low-Earth orbit.
The first-stage booster supporting the mission is expected to land on a droneship in the Pacific Ocean following stage separation.
This launch will be the 72nd from the base since the start of the year.
