>>> 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

>>> There are several changes to the Falcon 9 countdown that were first
>>> introduced Jan. 14 on a launch from California, the first SpaceX mission
>>> after a rocket exploded on a launch pad at Cape Canaveral Air Force Station
>>> in September.
>>>
>>> Engineers changed the filling sequence to avoid the problem of liquid
>>> oxygen becoming trapped in voids between helium pressurant tanks and their
>>> composite overwraps, which SpaceX says most likely caused the explosion
>>> last year.
>>>
>>> When it debuted a more capable Falcon 9 configuration burning
>>> super-chilled densified propellants in 2015, SpaceX shortened its launch
>>> countdowns to begin pumping fuel and oxidizer into the rocket just 35
>>> minutes before blastoff. SpaceX’s previous Falcon 9 countdowns followed a
>>> practice employed universally on cryogenically-fueled rockets worldwide, in
>>> which propellants are loaded aboard several hours ahead of launch.
>>>
>>> The “load and go” countdowns caused headaches at first, leading to
>>> several aborts and delays before SpaceX gained experience with the practice
>>> early last year. The late fueling plan has also drawn questions from NASA
>>> safety advisors, who worry the procedure will endanger astronauts strapped
>>> into to SpaceX’s Crew Dragon spaceships, which the company is developing to
>>> ferry people to and from the space station.
>>>
>>> The timeline for today’s countdown calls for RP-1 kerosene, chilled to
>>> around 20 degrees Fahrenheit (minus 6 degrees Celsius), to begin flowing
>>> into the two-stage rocket at T-minus 70 minutes. Liquid oxygen loading will
>>> follow at T-minus 45 minutes.
>>>
>>> A poll of the SpaceX launch team is expected at T-minus 78 minutes to
>>> give a "go" for fueling operations.
>>>
>>> 03/30/2017 17:50
>>>
>>> The danger area around the Falcon 9's launch pad is reported clear for
>>> the start of propellant loading operations.

>>>>>>>>>
>>>>>>>>> Like all launches, the flight is risky, but SES officials and

>>>>>>>>>
>>>>>>>>> Martin Halliwell, chief technology officer of Luxembourg-based

>>>>>>>>> “We’ve been through this thing with a fine-toothed comb,”
>>>>>>>>> Halliwell said Tuesday. “SpaceX has been through this with a fine-toothed
>>>>>>>>> comb. This booster is a really good booster, and we’re confident in this
>>>>>>>>> one.”
