SpaceX is set to launch the latest trio of AST SpaceMobile’s BlueBird satellites from Cape Canaveral Space Force Station in the predawn hours of Wednesday morning.

The Falcon 9 rocket will carry satellites numbered 11, 12, and 13 in to orbit. The mission comes about a month-and-a-half after SpaceX launched the BlueBird 8-10 mission.

Liftoff from Space Launch Complex 40 is scheduled during a window that opens at 3:42 a.m. EDT (0742 UTC). The rocket will fly on a northeasterly trajectory upon leaving the pad.

Spaceflight Now will have live coverage beginning about an hour and 20 minutes prior to liftoff, partially to account for the anticipated impact on the Moon of an unrelated Falcon 9 rocket upper stage.
