A United Launch Alliance Delta 4 rocket will deliver the U.S. Air Force’s tenth Wideband Global SATCOM communications satellite to a supersynchronous transfer orbit around 37 minutes after lifting off from Cape Canaveral.

A Falcon 9 rocket aborts its lift off at the final moment on February 28, 2016, as seen from the press site at Cape Canaveral Air Force Station. The rocket was supposed to launch the SES 9 communication satellite and had already been delayed by fueling problems and a boat that strayed into the launch danger area off shore.

SpaceX launched a Falcon 9 rocket from Cape Canaveral Sunday morning with 22 upgraded Starlink internet satellites, but officials called off a second Falcon 9 launch later in the day due to high winds in the booster’s offshore recovery area.
