The launch of the ULA #DeltaIVHeavy #NROL44 mission has been scrubbed. The local weather resulted in a significant delay to pre-launch preparations including the roll of the Mobile Service Tower (MST).


2 ч. назад

When the MST roll began we discovered a hydraulic leak in the ground system required to move the tower which needs further evaluation. Subsequent weather will prevent the team from moving forward with tonight's attempt. Launch is now scheduled for 11:54 pm EDT on Wed., Sept. 30.

About that lightning bolt @torybruno ...
I do believe my remote camera caught that moment. Mighty #DeltaIVHeavy looks good on the pad though.

Tower strike!    Our remote camera captured SLC-37's lightning suppression system in action, diverting damage away from #DeltaIVHeavy @NatReconOfc. This may have been the strike @torybruno mentioned.... Others nearby also #NROL44 #Lightning

С тех пор как одноблоковая Дельта-4 перестала летать и пуски стали совсем редкими SLC–37 явно пришла в упадок.

Welcome to the Delta IV Heavy Countdown!


From Cape Canaveral Air Force Station in Florida, this is Delta Launch Control at T-minus 8 hours and holding.

We are about to begin rollback of the Mobile Service Tower and initiate the countdown to launch the Delta IV Heavy rocket on the NROL-44 mission for the National Reconnaissance Office tonight.

Launch is scheduled for 11:54 p.m. EDT (0354 UTC) from Space Launch Complex-37.

The countdown will begin inside the Delta Operations Center at 3:24 p.m. EDT. Two pre-planned, 15-minute built-in holds are scheduled in the count. One pause is reserved prior to fueling at T-minus 4 hours, 15 minutes, the other occurs prior to the terminal count at T-minus 4 minutes.

MST Roll is Underway


At Space Launch Complex-37, retraction of the Mobile Service Tower is underway in preparation for tonight's Delta IV Heavy rocket launch of NROL-44.

ULA Launch Director Lou Mangieri gave approval for the gantry rollback following a weather briefing a short time ago. After verifying all steps in the pre-roll procedure were complete and acceptable weather, Launch Conductor Scott Barney radioed the pad crew to proceed with hydraulically raising the tower and moving it to the launch position.

The tower was raised a few inches using 40 hydraulic cylinders at pressures nearing 3,500 psi. The undercarriage transport system began moving the 33-story building with first motion at 2:57 p.m. EDT (1857 UTC).

The MST has moved 25 feet clear of the rocket thus far.

The gantry stands 330 feet tall, weighs nearly 10 million pounds and is the integral element that enables vertical integration of payloads atop the Delta IV Heavy. The tower is being wheeled on rail tracks about the length of a football field away from the rocket for tonight's scheduled launch.

Countdown Begins!


Countdown clocks have started ticking here in the Delta Operations Center towards a liftoff time of 11:54 p.m. EDT (0354 UTC).

Tonight's mission is a partnership between United Launch Alliance (ULA) and the National Reconnaissance Office (NRO). Our Delta IV Heavy will launch NROL-44, a national security payload designed, built and operated by the agency.

NROL-44 supports NRO's overall national security mission to provide intelligence data to the United States' senior policy makers, the Intelligence Community and Department of Defense.

The Delta IV Heavy, one of the world's most powerful rockets, is the only rocket system that possesses all of the attributes to meet the stringent requirements to launch the NROL-44 mission.

This will be ULA's 141st mission and our 29th for the NRO. The Delta IV Heavy is making is 12th flight overall and its 8th launch performed the NRO.

The triple-core rocket stands 235 feet tall and 54 feet wide, features 8 fuel and oxidizer tanks, burns liquid hydrogen and liquid oxygen in all three cores and its second stage, and protects the payload in a 65-foot-long tri-sector payload fairing.

The application of power to the avionics aboard the Delta IV Heavy rocket is beginning at the start of the countdown. The equipment will be powered up for launch day testing and final preparations for fueling operations.

Launch Weather is 80% GO


The updated launch forecast for tonight from the Space Force's 45th Weather Squadron here at Cape Canaveral indicates an 80 percent chance of acceptable conditions. The primary concern will be the thickness of clouds draped over the launch site from a cold front.

For launch at 11:54 p.m. EDT, meteorologists are predicting a broken deck of low clouds, good visibility, northerly winds of 12 to 18 knots and a temperature near 74 degrees F.

There is no concern for lightning or rainfall at the Cape this evening, after two days of inclement weather.

This is Delta Launch Control at T-minus 7 hours, 10 minutes (L-7 hours, 40 minutes) and counting. The Delta IV rocket has been powered up for the NROL-44 launch.

The flight control operator in the Launch Control Center performed the power up. Soon, he will begin avionics testing while the rocket's Inertial Guidance and Control Assembly (INCA) flight computer is allowed to warm up. Later, the operator will conduce guidance system testing and steering checks of the engine nozzles prior to cryogenic fueling

MST Rolled Back


The Mobile Service Tower at Space Launch Complex-37 has been retracted and secured in the launch position, revealing the United Launch Alliance Delta IV Heavy rocket for the NROL-44 launch.

The MST reached the "harddown" milestone at 4:24 p.m.

The flight control operational test for the Delta IV Heavy has been completed successfully. This test is known as flight slews, which performs gimbal checks of the rocket's engine nozzles in a state prior to cryogenic fueling. A similar test wull be conducted after the rocket is loaded with super-cold propellant.

The initiation of gaseous nitrogen flow to the rocket is starting. This changes the environmental control system to supply conditioned nitrogen gas rather than air to Delta IV Heavy in preparation for the cryogenic fueling and in-flight environments.
