United Launch Alliance

Опубликовано: 12 мар. 2019 г.

ULA will launch the 10th Wideband Global SATCOM (WGS-10) on a Delta IV Medium (5,4) on Friday, March 15, 2019. The launch is scheduled for 6:56 p.m. EDT from Space Launch Complex-37 at Cape Canaveral Air Force Station from Florida's Space Coast.

WGS-10 is the fourth Block II follow-on satellite and supports communications links in the X-band and Ka-band spectra. While Block I and II satellites can instantaneously filter and downlink up to 4.410 GHz, WGS-10 can filter and downlink up to 8.088 GHz of bandwidth. Depending on the mix of ground terminals, data rates and modulation and coding schemed employed, a single WGS satellite can support data transmission rates over 6 Gbps, and WGS-10 with its advanced digital channelized may support over 11 Gbps.

WGS-10 will be with eight flight of the Delta IV Medium+ (5,4) configuration. All launches in this configuration have delivered WGS missions to orbit. This mission will also be the 39th launch of the Delta IV since its inaugural launch in 2002.

United Launch Alliance ground crews are putting the final touches on a Delta 4 rocket scheduled for blastoff Friday evening from Cape Canaveral with a U.S. Air Force communications satellite.

The 218-foot-tall (66-meter) Delta 4 rocket is set for liftoff at 6:56 p.m. EDT (2256 GMT) Friday, around a half-hour before sunset on Florida's Space Coast. Friday night's launch window extends until 9:05 p.m. EDT (0105 GMT).

The payload for the Delta 4 rocket is the Air Force's Boeing-built WGS 10 communications satellite, which will join a fleet of wideband relay nodes stationed around the world in geostationary orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator.

Friday evening's mission will be the third launch of the year from Cape Canaveral, and ULA's second mission of 2019, following a Delta 4-Heavy flight Jan. 19 from Vandenberg Air Force Base in California.

The Delta 4 launcher, covered in orange thermal insulation over its cryogenic propellant tanks, will blast off with 1.8 million pounds of thrust and head due east from Cape Canaveral, releasing four Northrop Grumman-built strap-on solid rocket motors around a minute-and-a-half into the flight to fall into the Atlantic Ocean. The four solid rocket boosters should leave a twisting exhaust plume in their wake as the Delta 4 climbs into space, adding to the spectacle for beachgoers and space enthusiasts hoping to see the launch.

The Delta 4 will jettison the protective aerodynamic shroud over the WGS 10 spacecraft nearly two minutes later, and the rocket's core stage hydrogen-fueled RS-68A main engine, made by Aerojet Rocketdyne, will shut down at T+plus 3 minutes, 55 seconds.

Seconds later, the Delta 4's lower stage will drop away, and the upper stage's RL10B-2 engine will ignite for around 15 minutes to place the WGS 10 spacecraft in a preliminary parking orbit. A restart of the RL10B-2 engine at T+plus 29 minutes, 29 seconds, will raise the high point of the rocket's orbit to an altitude of 27,536 miles (44,315 kilometers), setting up for deployment of the more than 13,000-pound (nearly 6,000-kilogram) WGS 10 satellite at T+plus 36 minutes, 50 seconds.

Like its predecessors already in orbit, the Air Force's 10th Wideband Global SATCOM communications satellite will route classified and unclassified data and video, supporting U.S and allied forces around the world. Featuring a digital channelizer, WGS 10 will relay high-data-rate communications in X-band and Ka-band frequencies during a mission expected to last at least 14 years.

The nine previous WGS satellites all launched on ULA rockets — the first two on Atlas 5s in 2007 and 2009, and the following seven on Delta 4s.

"ULA is proud to be the exclusive launch provider for all ten WGS missions," said Gary Wentz, ULA vice president of government and commercial Programs. "Our focus on mission success continually demonstrates that safely and reliably delivering these critical national assets is our highest priority."

The weather outlook for Friday night's launch looks favorable, with a 70 percent probability of acceptable conditions. The only potential weather concern forecast by the Air Force's 45th Weather Squadron is the possibility of violating the cumulus cloud rule during the countdown.

"During the launch window, there is a slight possibility of an isolated shower early in the window as any showers that form inland could move back over the coast with southwesterly steering flow before diminishing shortly after sunset," the Air Force's forecast team wrote Wednesday.

At launch time, forecasters predict scattered clouds at 3,000 feet, broken clouds at 28,000 feet, and winds of 15 knots from the south-southeast. The temperature at launch time is forecast to be around 72 to 75 degrees Fahrenheit.

If the launch is delayed to Saturday, weather conditions are expected to worsen as a cold front moves into Central Florida. There is a 60 percent probability of weather conditions violating one of the Delta 4's launch weather rules Saturday.

The Delta 4's launch with the WGS 10 communications satellite was previously scheduled for Wednesday, March 13. ULA announced a two-day delay Saturday "to allow for additional troubleshooting to resolve some off-nominal data indications."

ULA and Air Force officials are scheduled to meet Thursday morning for a launch readiness review to clear the Delta 4 rocket for final countdown preparations.

Tenth WGS satellite to serve U.S. warfighters

March 13, 2019 -- United Launch Alliance will deliver the tenth communications satellite into space for the U.S. military's Wideband Global SATCOM constellation with the launch of WGS-10 aboard a Delta IV rocket on Friday.



The launch is scheduled for 6:56 p.m. EDT (2256 UTC) from Space Launch Complex-37 at Cape Canaveral Air Force Station, Florida. The evening's launch window extends to 9:05 p.m. EDT (0105 UTC), a duration of 129 minutes.

The WGS satellites operate in geostationary orbit 22,300 miles above Earth and serve as the backbone for communications "anytime, anywhere" around the world for troops, aircraft, ships. 

"ULA is proud to be the exclusive launch provider for all ten WGS missions," said Gary Wentz, ULA vice president of Government and Commercial Programs. "Our focus on mission success continually demonstrates that safely and reliably delivering these critical national assets is our highest priority."
Joining the U.S. in the WGS system are the partner nations of Australia, Canada, the Czech Republic, Denmark, Luxembourg, the Netherlands, Norway and New Zealand. They have financed aspects of the program in exchange for global communications services.

Boeing built the 10 spacecraft in the program at its factory in El Segundo, California. The craft use the Boeing 702HP bus with conventional and xenon-ion propulsion systems, highly efficient triple-junction gallium arsenide solar cells and deployable radiators with flexible heat pipes.

The solar arrays on each satellite stretch 135 feet tip-to-tip, a wingspan larger than a Boeing 737 but smaller than a Boeing 747. Each craft weighs about 13,000 pounds at launch.

The WGS satellites place shaped, steerable spot beams of bandwidth for Ka- and X-band frequencies, plus the onboard capability to switch signals from one band to the other. Each satellite has electrically-steerable, phased array antennas for X-band transmitting and receiving, mechanically-steered Ka-band antennas and a fixed full-Earth-coverage beam also in X-band. The antennas provide 19 independent coverage areas — 10 Ka-band and 8 X-band spot beams, plus the full-Earth footprint.

The Delta IV Medium+ (5,4) rocket will be powered into the evening sky by its RS-68A main engine and four side-mounted solid rocket motors, heading eastward above the Atlantic Ocean.



The solids will burn out and jettison about 100 seconds into flight, followed by payload fairing separation two minutes later and staging of the common booster core first stage from the Delta Cryogenic Second Stage (DCSS) four minutes after liftoff.

The second stage will perform two firings of its RL10B-2 engine, one for 15 minutes to reach a parking orbit and a second time for three-and-a-half minutes to achieve the targeted super-synchronous transfer orbit to deploy WGS-10. Spacecraft separation is expected 37 minutes after launch.

This will mark ULA's 133rd flight, the 383rd Delta launch in history and our second Delta IV launch this year.

The launch weather forecast calls for some scattered clouds, good visibility, a chance of showers inland, southeasterly winds of 15 knots and a temperature in the low 70s F. There is a 70 percent chance of favorable liftoff weather conditions, with cumulus clouds the primary concern.

Launch Readiness Review completed

The Mission Management Team has given a "go" for liftoff of the United Launch Alliance Delta IV rocket carrying the Wideband Global SATCOM (WGS)-10 communications spacecraft for the Air Force on Friday.

The Launch Readiness Review, chaired by Tom Heter III, ULA's launch director for WGS-10, was completed this morning at the Delta Operations Center. Leaders from ULA and the Air Force assessed all aspects pf mission readiness, discussed the status of pre-flight processing work, heard technical overviews of the countdown and flight, and previewed the weather forecast.

At the conclusion of the meeting, the managers were polled, gave a unanimous "go" for launch and then signed the Launch Readiness Certificate.

Friday's launch is scheduled for 6:56 p.m. EDT (2256 UTC) from Space Launch Complex-37 at Cape Canaveral Air Force Station, Florida.

The official launch weather forecast, according to the 45th Weather Squadron, now calls for an 80 percent chance of favorable conditions for the liftoff, with scattered low clouds and broken high-level clouds, south-southeasterly winds at 12 peaking to 16 knots and a temperature in the mid 70s F. The only concern for a launch weather rule violation will be cumulus clouds.

United Launch Alliance will provide complete live coverage of the countdown in this blog starting at 10:15 a.m. EDT (1415 UTC). Our Live Launch Updates Blog brings you official and timely information during the Delta IV rocket's countdown with automatically-refreshing updates.

It's launch day at Cape Canaveral, where a Delta 4 rocket is set for liftoff at 6:56 p.m. EDT (2256 GMT) carrying the U.S. Air Force's tenth Wideband Global SATCOM communications satellite into orbit.

One of the first steps this morning in preparation for launch will be the retraction of the Delta 4's mobile gantry at the Complex 37B launch pad. The 330-foot-tall structure will roll away from the Delta 4 to its launch position just northeast of the pad.

The tower protected the rocket from weather during launch preparations, and helped workers access the launcher since it arrived at the pad in late January. The tower weighs about 9 million pounds, and is one of the tallest launch pad structures at Cape Canaveral.

The first few hours of today's countdown will include the power-up of the Delta 4 rocket, checkout of its guidance and control systems, and final securing of the vehicle and the launch pad before workers evacuate the area in advance of fueling.

Two built-in holds are planned in today's countdown at T-minus 4 hours, 15 minutes, and at T-minus 4 minutes.

Filling of the Delta 4 rocket with super-cold liquid hydrogen and liquid oxygen, which powers both stages of the launcher, should begin soon after 2 p.m. EDT (1800 GMT).

We are pleased to provide full coverage of today's launch after United Launch Alliance reversed its earlier decision not to provide the news media with countdown audio for its launches.

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 this evening's liftoff of the United Launch Alliance Delta IV rocket to deploy the tenth Wideband Global SATCOM (WGS-10) military communications satellite for the U.S. Air Force.

Launch is scheduled for 6:56 p.m. EDT (2256 UTC) from Space Launch Complex-37. The available launch window today extends to 9:05 p.m., a duration of two hours and 9 minutes.

The countdown will start at 10:26 a.m. EDT from the T-minus 8 hour mark. Two pre-planned, 15-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!

We are heading into space tonight, and the countdown has been initiated! We are just eight-and-a-half hours away from liftoff of the Delta IV Medium+ (5,4) rocket to add the tenth satellite to the U.S. military's Wideband Global SATCOM constellation, the backbone of worldwide communications connectivity for American and allied military forces.

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

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 day.

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 afternoon hours when the vehicle will be exposed during fueling operations also poses no concern for lightning or high winds.

For launch this evening at 6:56 p.m. EDT, meteorologists are predicting scattered and high broken clouds, good visibility, south-southeasterly winds of 12 knots, gusting to 16 knots and a temperature in the mid 70s F.

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

The primary concern will be any showers forming inland and migrating back towards the coast to violate the cumulus cloud rule. Even if that happens, meteorologists say the no-go condition should not linger too long.
