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 14th launch of the year, and the 91st 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).

The strongback structure next to the Falcon 9 rocket at pad 40 is being chilled down in preparation for loading of super-cold liquid oxygen into the launcher's second stage, which begins at T-minus 16 minutes.

The second stage of the Falcon 9 is confirmed fully loaded with RP-1 kerosene fuel at this time.

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 1 minute, 45 seconds. The second stage's liquid oxygen tank is filled and has been closed out for flight.

The Falcon 9 rocket is now fully loaded with kerosene and liquid oxygen propellant, weighing about 1.2 million pounds.

SpaceX just launched the eleventh Starlink mission. What makes this one special is B1049.5 just launched and landed for the sixth time with reused fairing as icing on the cake. Looks like this booster did just fine leaving Earth.
