View of the launch pad tonight. We are so close from our current location (still safe) that I had to use my smaller zoom lens. @Teslarati

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.

The process to lower the strongback structure at pad 40 has begun with the opening up the cradles around the rocket. The strong back will move to an angle of around 1.5 degrees from the Falcon 9 in preparation for ignition, then further retract at liftoff.
