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.</p><p>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.</p><p>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.</p><p>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.</p><p>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.</p><p>A poll of the SpaceX launch team is expected at T-minus 78 minutes to give a "go" for fueling operations.</p></div><div id="div-196269324" class="blogdiv" style="padding:5px 10px;margin-top:5px"><p style="font-weight:bold;color:#ce4b27;margin-bottom:5px"><time title="2017-03-30 17:50:08">03/30/2017 17:50</time></p><p>The danger area around the Falcon 9's launch pad is reported clear for the start of propellant loading operations.</p></div><div id="div-196269323" class="blogdiv" style="padding:5px 10px;margin-top:5px"><p style="font-weight:bold;color:#ce4b27;margin-bottom:5px"><time title="2017-03-30 17:49:43">03/30/2017 17:49</time> Flight timeline</p><p><a href="http://24liveblog.com/show?img=//cdn5.24live.co/images/2017/03/31/1490906524640396.png" target="_blank"><img src="https://cdn5.24live.co/images/2017/03/31/1490906524640396.png" style="margin-right: 0px;" width="401" height="385"></a></p><p>SpaceX’s
