GO for Launch!


The ULA Launch Director Lou Mangieri has confirmed that the Delta IV Heavy rocket is ready to fly and NRO Mission Director Col. Chad Davis has given final permission to launch. That concurrence was made following a readiness poll of the launch team by Launch Conductor Scott Barney that verified all systems are "go."

This is Delta Launch Control at T-minus 4 minutes and holding with less than a minute remaining in this built-in hold.

The launch pad swing arm lock pins have retracted. All steps are complete prior to terminal count.

Countdown Resumes


T-minus 4 minutes and counting. The final phase of tonight's countdown is underway at Cape Canaveral to launch the Delta IV Heavy rocket on NROL-44. The countdown clocks have resumed, leading us straight to liftoff.

Over the next minute, the Delta Cryogenic Second Stage liquid oxygen tank will be secured at flight level, replenishment of liquid hydrogen and liquid oxygen to the three common core boosters will be secured in preparation to pressurize the tanks for launch and the ground pyrotechnics will be enabled.

T-minus 2 minutes, 30 seconds. We remain GO for liftoff of the Delta IV Heavy and the flight of Delta 385.

The liquid oxygen tanks in the three common booster cores are been confirmed at the proper level and pressure for flight. The liquid hydrogen tanks will achieve this status less than a minute from now.

The liquid hydrogen system on the Delta Cryogenic Second Stage will be secured starting at T-minus 80 seconds.

T-minus 1 minutes, 55 seconds. The launch sequencer has been started. It will perform independent verifications of systems for the rest of the countdown, control the firing of hydrogen burnoff igniters under the engines, detachment of umbilicals from the vehicle and release the rocket from the pad at liftoff.

The Delta IV Heavy rocket has switched from ground-fed power to internal batteries. Shortly, ordnance devices aboard the vehicle will be armed. The flight software on the vehicle will go active at T-minus 80 seconds.

T-minus 55 seconds and counting. Computers have verified that the three RS-68A main engines are ready for ignition and the Space Force's Eastern Range at the Cape has confirmed its "green" condition for launch.

Coming up at T-minus 30 seconds, a final status check will be announced on Delta and NROL-44 readiness, followed by the vehicle going inertial, the residual hydrogen burnoff sparklers firing beneath the main engines, the Terminal Countdown Sequencer Rack going active and the staggered ignitions of the main engines starting at T-minus 7 seconds with the starboard booster and T-minus 5 seconds for the center and port boosters. The 12 holddown bolts will fire to release the vehicle for liftoff at T-0 and the swing arms on the launch pad will pull back.

The Terminal Countdown Sequencer Rack (TCSR) called a hold at T-minus 7 seconds. TCSR controls the final 10 seconds of the countdown. The safety system worked as intended to stop the countdown if a problem is detected.
