2321 GMT (6:21 p.m. EST)
 Still no word if the problem that caused the abort has been formally resolved.
 
2318 GMT (6:18 p.m. EST)
 NEW LAUNCH TIME. The countdown clock has resumed for another launch attempt 6:44 p.m. EST (2344 GMT).

2324 GMT (6:24 p.m. EST)
 Spacecraft engineers say they are willing to extend the launch window by 20 minutes to give more time to resolve whatever issue is being worked in the countdown.

2328 GMT (6:28 p.m. EST)
 A poll of the SpaceX launch team is scheduled for the T-minus 13 minute point in a few minutes.

[Liss]

T-8:00.
Пошли на вторую попытку.

[Salo]

2334 GMT (6:34 p.m. EST)
T-minus 10 minutes and counting. The terminal countdown autosequence has started. Any hold after this point will result in an automatic abort and recycle to T-minus 13 minutes.

2332 GMT (6:32 p.m. EST)
All stations on the launch team report they are GO for launch at 6:44 p.m. EST (2344 GMT).

Increasing helium spin start pressure. Probably <50% chance of passing all aborts, but worth a try. Countdown resuming ...

[Salo]

2337 GMT (6:37 p.m. EST)
T-minus 6 minutes, 30 seconds. The Falcon 9's heaters are being deactivated, and the rocket will be transitioned to internal power in a few seconds.

2337 GMT (6:37 p.m. EST)
T-minus 7 minutes and counting. Within the next minute, the Falcon 9's flight computer will be commanded to its alignment state. The Merlin engine pumps are continuing to chill down.

The launch danger area around Cape Canaveral is clear for launch.

2336 GMT (6:36 p.m. EST)
T-minus 8 minutes and counting. Good chilldown continues on the first stage engines, and closeouts of the upper stage's gaseous nitrogen attitude control system are underway.

2335 GMT (6:35 p.m. EST)
T-minus 9 minutes and counting. 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.

If launch aborts, we will bring the rocket down for engine inspection, so probably a few days before next attempt

2328 GMT (6:28 p.m. EST)
ABORT. Clocks have stopped at T-minus 48 seconds.

2329 GMT (6:29 p.m. EST)
T-minus 60 seconds. In the final minute of the countdown, the flight computer will command checks of the first stage Merlin engine steering system and the Falcon 9 propellant tanks will be pressurized for flight. Thousands of gallons of water from the ground facility's Niagara system will also be dumped onto the launch pad deck to suppress the sound and acoustics of liftoff.

The command to start the ignition sequence for the first stage will be issued at T-minus 3 seconds, triggering the Merlin engines' ignitor moments before the powerplants actually ramp up to full power.

2328 GMT (6:28 p.m. EST)
T-minus 90 seconds and counting. The SpaceX launch director and the Air Force Eastern Range have given their final approvals for liftoff of the Falcon 9 rocket at 5:37 p.m. EST (2237 GMT).

2342 GMT (6:42 p.m. EST)
T-minus 2 minutes and counting. The rocket's Merlin 1D engines have been chilled down for ignition.

2341 GMT (6:41 p.m. EST)
T-minus 2 minutes, 30 seconds. The strongback has been locked in to launch position.

2340 GMT (6:40 p.m. EST)
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.

The strongback has retracted into the launch position more than 20 degrees from the rocket.

The second stage thrust vector steering system has checked out and is ready for flight.

2339 GMT (6:39 p.m. EST)
T-minus 5 minutes and counting. The cradles connecting the strongback to the Falcon 9 rocket have opened.

2338 GMT (6:38 p.m. EST)
T-minus 6 minutes and counting. The Falcon 9 rocket is now operating on internal power.

The strongback umbilical tower will soon be lowered a few degrees to clear the rocket for launch. The procedure begins with opening of cradles gripping the rocket at attach points, then hydraulics lower the tower into launch position.
