Inside T-1 hour. #Falcon9 has entered prop load as planned and is counting toward liftoff at 1:00 UTC. After tanking starts, the available window time is shortened due to propellant temperature requirements.

SpaceX's live coverage of today's launch will be different than normal. The company's webcast coverage of the ascent portion of the flight will end around 3 minutes after liftoff, once the Falcon 9's payload fairing is jettisoned, at the request of the mission's U.S. government customer.

Live video of the first stage's descent and landing will continue, with touchdown se t for T+plus 7 minutes, 56 seconds, at Landing Zone 1 at nearby Cape Canaveral Air Force Station.

Follow the major events of the launch and landing with this timeline.
