[Steven Pietrobon]

T-6 minutes. Stage 1 fuel load complete.

[ZachS09]

T-5 minutes. Tanks are pressing for strongback retraction.

[Steven Pietrobon]

T-5 minutes. Vehicle is in self align.

[ZachS09]

T-4 minutes. The strongback clamps underneath the fairing are opening.

This strongback will be lowered 1.5 degrees from its prelaunch position. At T0, the strongback will retract quickly similar to the TEL that supports the Antares rocket.

[Steven Pietrobon]

T-4 minutes. M1-D fuel bleed has started.

[andrewsdanj]

Very interesting - constant thrust of 190klb all the way up rather than constant chamber pressure.

[ZachS09]

T-3 minutes. Everything continues to proceed smoothly with the upcoming first launch of Falcon 9 Block 5.

Checking the engine TVC systems.

[Steven Pietrobon]

T-3 minutes. Stage 1 LOX load complete.

[ZachS09]

T-2 minutes. Launch vehicle is on internal power.

[ZachS09]

T-90 seconds. The Eastern Range and the weather remain GO for launch.

[Chris Bergin]

Chopper or drone view.

[Steven Pietrobon]

T-2 minutes. Stage 2 LOX load complete.

[ZachS09]

T-60 seconds. The Automatic Flight Termination System is READY for launch and the launch vehicle is in start-up mode.

[ZachS09]

T-58 seconds and holding.

[Joey S-IVB]

Launch abort at -58

[ZachS09]

Vehicle is being safed and the strongback will soon raise to its prelaunch position.

[Steven Pietrobon]

T-1 minute.

Abort!

[andrewsdanj]

HOLD at T-58s.

[ZachS09]

Count has been reset to T-15 minutes.

Standing by to hear what the abort was caused by.
