The countdown continues toward liftoff at 10:36 a.m. EST, 10 minutes from now. During this time, the Falcon 9’s engines will be chilled to condition them for launch, the flight computer will run its prelaunch checks and the rocket’s propellant tanks will be brought to flight pressure. Finally, SpaceX Launch Director John Muratore will verify “go for launch.”
About three minutes prior to launch, the gantry-like strongback support structure will be lowered away from the rocket. The terminal countdown begins at T-30 seconds.
