A United Launch Alliance Vulcan rocket is set for its second certification flight from Cape Canaveral Space Force Station this weekend. The rocket rolled out to Launch Complex 41 on Monday, and is now scheduled to launch on Friday. The mission, known as Cert-2, aims to further validate the Vulcan rocket’s capabilities as part of ULA’s ongoing efforts to enhance space launch services. Liftoff is set for Friday sometime during a window that opens at 6am and closes at 9am. But before that one, SpaceX is still planning the next Starlink mission. If it goes up as now scheduled, it will mean a Falcon 9 launch a little earlier Friday morning, sometime during a window that opens Friday at 4:05am and closes at 8:35am. The first stage will land on a drone ship in the Atlantic Ocean.
