T-minus 35 minutes. Filling of the Falcon 9 rocket with super-chilled, densified kerosene and liquid oxygen is underway at Cape Canaveral. This will mark SpaceX's 16th launch of the year, and the 93rd flight of a Falcon 9 rocket since June 2010.

The liquid oxygen flowing into the first stage is chilled to near minus 340 degrees Fahrenheit (minus 206 degrees Celsius).

Propellant loading begins with pumping RP-1 kerosene into both stages of the Falcon 9 rocket, and liquid oxygen into the first stage. Liquid oxygen begins loading into the second stage at T-minus 16 minutes.

T-minus 7 minutes. Prevalves leading to the Falcon 9's Merlin 1D first stage engines are opening, permitting super-cold liquid oxygen to flow into the engines to condition the turbopumps for ignition.

T-minus 5 minutes. The Falcon 9's propellant tanks are being pressurized in preparation for retraction of the strongback structure at pad 39A.

T-minus 4 minutes, 15 seconds. The process to lower the strongback structure at pad 39A has begun with the opening up the cradles around the rocket. The strongback will move to an angle of around 1.5 degrees from the Falcon 9 in preparation for ignition, then further retract at liftoff.
