No Central Florida sonic booms are expected. After soaring skyward along a southeasterly trajectory, the rocket's first-stage booster will target landing aboard a drone ship out at sea 8? minutes after liftoff.

Launch window: 6:40 p.m. to 11:11 p.m.
Location: Launch Complex 40 at Cape Canaveral Space Force Station.
Trajectory: Southeast.
Local sonic boom: No.
Booster landing: Drone ship out on the Atlantic Ocean.

Space Force: 90% favorable launch weather
Update 4:10 p.m.: The Space Force's 45th Weather Squadron predicted 90% "go for launch" weather conditions at Cape Canaveral for today's SpaceX liftoff. Thick cloud layers pose the primary meteorological risk.
"A surface ridge of high pressure extending from the central Atlantic to the Florida peninsula will remain largely in place the next several days as a series of systems pass by well to the north," the squadron's forecast said.
"While moisture in the lower atmosphere will be limited and shallow, variable upper-level cloudiness is expected to spill over a ridge centered across the Gulf of Mexico and make its way into Florida," the forecast said.
