T-minus 70 minutes. The launch autosequence has started, kicking off the first steps to begin pumping propellants into the 229-foot-tall Falcon 9 at launch pad 39A.

RP-1 kerosene will be pumped into the two-stage Falcon 9 rocket first, followed by liquid oxygen chilled to near minus 340 degrees Fahrenheit (minus 206 degrees Celsius) at T-minus 45 minutes.

Falcon 9 will experience its highest ever reentry force and heat in today's launch. Good chance rocket booster doesn't make it back.

Сегодняшний эксперимент будет особенно бесчеловечным.

Super-chilled, densified liquid oxygen should now be flowing into the two-stage Falcon 9 rocket.
Both stages of the launcher burn the same RP-1/liquid oxygen propellant mixture.

~60 minutes until Falcon 9 launch of BulgariaSat-1. Webcast will go live about 15 minutes before liftoff → http://spacex.com/webcast

There has been no confirmation of the start of liquid oxygen loading, but the countdown continues at T-minus 36 minutes and counting.

At least 3 LOX venting events seen from #Falcon9. Still no *official* confirmation, though, that LOX load is underway. #BulgariaSat #SpaceX

Puffs of vapor coming from the Falcon 9 rocket at pad 39A suggest liquid oxygen loading is underway.

Я правильно понял, Маск не уверен, что повторная ступень выдержит возвращение, поэтому и хочет устроить шоу, чтобы была возможность списать возможную неудачу ?

OCISLY waiting to catch a Falcon 9 booster. Remember, they've warned us this one may not make it back.
