SpaceX is planning a Saturday morning launch from Vandenberg Space Force Base that will send 24 Starlink satellites to low-Earth orbit.
The May 30 launch window for the Falcon 9 rocket is between 7 a.m. and 11 a.m., with liftoff from Space Launch Complex 4 East currently set for 8 a.m., according to SpaceX.
A livestream of the launch is expected to begin shortly before liftoff.
The first-stage booster supporting the mission has been used 21 times, including on 18 Starlink missions.
The first-stage is expected to land on a droneship in the Pacific Ocean following stage separation. No sonic boom is expected to be heard locally.
