Welcome to live coverage!

From the Delta Operations Center (DOC) at Cape Canaveral Air Force Station in Florida, this is Delta Launch Control at T-minus 8 hours and holding.

The countdown is about to begin for liftoff of the United Launch Alliance Delta IV rocket to deploy a Global Positioning System satellite for the U.S. Air Force Space and Missile Systems Center.

Launch is scheduled for 9:00:30 a.m. EDT (1300:30 UTC) from Space Launch Complex-37. The available launch window today extends to 9:27 a.m., a duration of 26 minutes and 30 seconds.

The countdown will start 30 seconds after 12 midnight EDT from the T-minus 8 hour mark. Two pre-planned, 30-minute built-in holds 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.

Countdown begins!

The countdown has been initiated! We are just nine hours away from liftoff of the Delta IV Medium+ (4,2) rocket to add an advanced satellite to the U.S. military's Global Positioning System constellation.

The application of power to the avionics aboard the Delta IV 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.

At Space Launch Complex-37, the Mobile Service Tower retraction to the launch position is scheduled to begin shortly. A check of the weather conditions will be made by mission managers five minutes from now.

Weather acceptable for tower roll

Launch Weather Officer Will Ulrich from the 45th Weather Squadron here at Cape Canaveral Air Force Station has provided a forecast of conditions expected during retraction of the Mobile Service Tower away from the Delta IV rocket and the outlook for the rest of the morning.

Current conditions are favorable to proceed with tower roll, with winds within limits and no adverse weather in the area. Also, the weather for the rest of the morning hours when the vehicle will be exposed during fueling operations also poses no concern for lightning or high winds.

For launch this morning at 9 a.m. EDT, meteorologists are predicting scattered clouds, good visibility, easterly winds of 6 to 10 knots and a temperature near 83 degrees F.

Overall, there is an 80 percent chance of favorable launch weather.

The primary concern will be any showers forming over the ocean and drifting towards the coast to violate the cumulus cloud rule.

GO for tower roll

We have concurrence to retract the Mobile Service Tower following a engineering readiness poll by the ULA launch director. That "go" has been passed to the launch conductor for implementation.


Aug 22 07:14
"Proceed with MST jacking and roll to the park position," Launch Conductor Dillon Rice just radioed to Stand Engineer John Daley at Space Launch Complex-37.


Aug 22 07:24
MST jacking is underway. Using 40 hydraulic cylinders at pressures nearing 3,500 psi, the tower will be raised a few inches in preparation for the roll.

A short time ago, the tie-down clamps at the base of the Mobile Service Tower were opened so technicians could proceed to hydraulically raise the gantry for the rollback. These large claw-like devices secure the MST to anchor points on the pad surface.


Aug 22 07:39
MST roll is underway

This is Delta Launch Control. Retraction of the Mobile Service Tower in progress at Space Launch Complex-37.

First motion occurred at 12:38 a.m. EDT (0438 UTC).

An undercarriage transport system will move the 33-story building at a top speed of 0.25 miles per hour.


Aug 22 07:41
T-minus 7 hours, 20 minutes (L-8 hours, 20 minutes) and counting. The Delta IV rocket has been powered up for its launch of GPS III SV02.

The flight control operator Jim Thomson 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.


Aug 22 07:45
The MST gantry stands 330 feet tall and weighs nearly 10 million pounds. It is being wheeled on rail tracks about the length of a football field away from the rocket for this morning's scheduled launch.

Guidance system testing is getting started at this point in the countdown as we continue to press ahead toward a liftoff at 9:00:30 a.m. EDT (1300:30 UTC).

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 rocket for its flight to place the GPS III SV02 navigation satellite into orbit for use by the U.S. warfighter and civilians around the world.

The MST reached the "harddown" milestone at 1:43 a.m.

The MST is a critical part of the launch complex, proving the primary access and weather protection to the rocket during its stay on the launch pad, and its overhead crane system serves a vital role in vertical integration of payloads onto the Delta IV rockets.

Rollback of the MST signals a major milestone at the start of launch day operations. Configuring launch pad systems and securing equipment will be completed over the next couple of hours before all personnel clear the site for fueling.

Activities remain on schedule for a liftoff at 9:00:30 a.m. EDT (1300:30 UTC).

SLC-37

Space Launch Complex-37 is the East Coast home of the Delta IV rocket at Cape Canaveral Air Force Station in Florida. "Slick-37" was constructed by NASA in the 1960s for uncrewed test flights in the Apollo-Saturn program.

There were six Saturn I and two Saturn IB rocket launches from this site between 1964 and 1968, testing rocket stages, spacecraft systems and the first lunar module.

The pad was rejuvenated in an extensive overhaul to support the Delta IV starting in late 1990s. The Fixed Umbilical Tower and swing arms were built, along with a Mobile Service Tower, a launch table and hydraulic erector system. And a nearby horizontal processing facility was constructed to house and integrate the main stages before rollout to the pad.

GPS III SV02 will be the 38th launch from this complex and the 32nd by a Delta IV.

L-minus 7 hours, mark.

The ULA launch team is controlling the countdown from the Delta Operations Center, or DOC, located about one-and-a-half miles from the launch pad. The Launch Control Center and Engineering Support Area are located on the third floor of the DOC and the Mission Director's Center is on the fourth floor. The Cape works in conjunction with design teams at ULA's Denver Operations Support Center, or DOSC.

Engineers and specialists from the Air Force and Aerospace Corp. are monitoring systems from consoles at Cape Canaveral's Hangar AE and Technical Support Facility.

Teams at the Astrotech payload processing facility in Titusville are monitoring he health of the GPS satellite atop the Delta IV rocket.

Range functions and weather forecasting duties are being performed by Air Force officials at the Morrell Operations Center here at the Cape.

Aug 22 09:08
The flight control operational test is beginning for the Delta IV rocket. This test is known as flight slews, which will perform gimbal checks of the rocket engine nozzles on the vehicle, in a state prior to cryogenic fueling.

The flight control operational test has been completed successfully. This was an engine nozzle steering check performed prior to cryogenic fueling. A similar test wull be conducted after the rocket is loaded with super-cold propellant.

All systems are "go" here at the Delta Operations Center (DOC) and at the Space Launch Complex-37 pad as we count down to today's launch at exactly 9:00:30 a.m. EDT (1300:30 UTC).
