T-minus 45 minutes. Today's liftoff is timed for 9:17:25 a.m. EDT (1317:25 GMT).
Around 61 minutes after launch, the Falcon 9 rocket will deploy the 60 Starlink satellites into near-circular transfer orbit ranging between 172 miles (278 kilometers) and 162 miles (261 kilometers), with an inclination of 53 degrees.

The satellites will use their ion thrusters to maneuver into their higher orbit for testing, before finally proceeding to an operational orbit at an altitude of approximately 341 miles (550 kilometers).

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.

10/01/2020 16:13 Stephen Clark

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.

T-minus 90 seconds and counting. Everything is on track for liftoff of the Falcon 9 rocket at 9:17:25 a.m. EDT (1317:25 GMT). The Falcon 9 is confirmed on internal power at this time.
