It's unclear what the late start of liquid oxygen loading means for tonight's scheduled launch time of 7:21 p.m. EDT (2321 GMT). Tonight's launch window extends until 8:10 p.m. EDT (0010 GMT).

The hydraulic systems on the Merlin engines reported at full pressure. The first stage's kerosene fuel tank has been topped off.

05/16/2017 02:15
John Insprucker, Falcon 9 product manager at SpaceX, reports fueling of the Falcon 9 rocket was delayed 10 minutes in an effort to condense the countdown. All systems are go for liftoff at 7:21 p.m. EDT (2321 GMT).

05/16/2017 02:15
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.

05/16/2017 02:16
The cradle arms on the strongback are opening for strongback retraction to launch position 1.5 degrees from the Falcon 9.

[tnt22]

05/16/2017 02:17
T-minus 3 minutes and counting. The rocket's destruct system is on internal power and being armed, and liquid oxygen topping is being terminated soon. A steering check on the upper stage engine should also be complete.

05/16/2017 02:19
T-minus 90 seconds and counting. Everything on track for liftoff of the Falcon 9 rocket at 7:21 p.m. EDT (2321 GMT).

LIFTOFF of the Falcon 9 with Inmarsat 5 F4, boosting a heavyweight 6.7-ton broadband communications satellite into orbit to support airline passengers, maritime crews and military units with mobile connectivity.

T+plus 2 minutes. Now soaring at an altitude of more than 20 miles, the Falcon 9 rocket's first stage will shut down and jettison in about 45 seconds.
And chilldown of the second stage's vacuum-rated Merlin 1D engine is starting in preparation for its ignition.

05/16/2017 02:22
T+plus 1 minute. The Falcon 9 rocket is approaching the speed of sound and the phase of maximum aerodynamic pressure as it heads east from Kennedy Space Center.

05/16/2017 02:24
T+plus 4 minutes. The Falcon 9's payload fairing has been jettisoned.

05/16/2017 02:24
T+plus 3 minutes. The Falcon 9 first stage engines have cut off, the stages have separated, and the rocket's second stage Merlin vacuum engine has ignited for its nearly six-minute firing to reach a preliminary parking orbit.
The first stage will fall into the Atlantic and not attempt a landing on this mission due to the lift requirements of the Inmarsat 5 F4 spacecraft.

05/16/2017 02:26
T+plus 6 minutes. SpaceX reports the second stage propulsion system is performing nominally. Altitude is 170 kilometer, and the velocity is 15,400 kilometers per hour.

05/16/2017 02:26
T+plus 5 minutes. Everything reported to be going well with this second stage engine firing. The Merlin vacuum engine uses an ultra-thin niobium nozzle extension for greater efficiency in the upper atmosphere.

The kerosene-fueled Merlin 1D upper stage engine generates about 210,000 pounds of thrust in vacuum.
