The Falcon 9 rocket is again standing vertical at pad 39A after being
raised upright around 4 a.m. EDT (0800 GMT) this morning.

Next up will be a series of checkouts and software uploads on the SES 10
communications satellite, followed by the start of Falcon 9 countdown
procedures this afternoon.

Final launch preps this afternoon will include the evacuation of the launch
pad prior to fueling, activation of the Falcon 9's computer and navigation
system, and a prelaunch poll by the SpaceX launch conductor at 5:09 p.m.
EDT (2109 GMT) to verify all consoles are "go" for the terminal countdown.

Super-chilled RP-1 kerosene fuel will be loaded first into the two-stage
booster, beginning around 5:17 p.m. EDT (2117 GMT). Liquid oxygen, chilled
and densified near its freezing point, will follow starting at around 5:42
p.m. EDT (2142 GMT).

The computer-controlled countdown will prep the rocket’s nine Merlin 1D
main engines for ignition, transition the Falcon 9 to internal battery
power, and pressurize the booster’s propellant tanks in the last 10 minutes
of the countdown.

The launch window opens at 6:27 p.m. EDT (2227 GMT) and runs until 8:57
p.m. EDT (0057 GMT). That is long enough to permit a recycle and a second
launch attempt should the first try be aborted in the final minutes or
seconds.
