The launch, a Starlink mission carrying 28 internet satellites to low-Earth orbit, is scheduled to take off from Space Launch Complex 40 during a four-hour launch window that opens at 9:51 p.m., according to SpaceX.

Liftoff is now set for 10:09 p.m. from Cape Canaveral Launch Complex 40. The Falcon 9 rocket will be carrying the Starlink 12-23 mission to orbit. This is the latest batch of SpaceX's Starlink internet satellites. Should SpaceX not be able to launch at 10:09 p.m., opportunities exist until 1:49 a.m. (April 28).
