CAPE CANAVERAL — The Delta 4 rocket that will launch the U.S. military's highest capacity communications satellite ever built was rolled to the pad this week.
The two-stage booster moved from the Horizontal Integration Facility to the Complex 37B pad and erected on the launch table to begin preparations for flight.
Liftoff is scheduled on or about Dec. 7 during a window of 6:53 to 7:42 p.m. EST (2353-0042 GMT), a duration of 49 minutes.
Over the next two months, using the classic launch pad design with a mobile service gantry, the rocket will undergo installation of four strap-on solid-fuel boosters, a rigorous checkout and testing campaign and mating of the satellite cargo.
The launcher will deliver the Wibdeband Global SATCOM satellite No. 8 into a supersynchronous transfer orbit for the U.S. Air Force.
WGS 8 will join seven previous sister-craft, all built by The Boeing Co., in geosynchronous orbit 22,300 miles above the planet that provide communications used by soldiers, ships, aircraft and drones.
But starting with the $426 million WGS 8 satellite, Boeing has included a significant upgrade to boost the spacecraft's capacity even further.
"WGS 8 includes an enhanced channelizer that provides a 90 percent improvement in satellite-available bandwidth compared previous WGS satellites," said Col. Timothy Sejba, the MILSATCOM Systems Directorate's deputy director at the Space and Missile Systems Center at Los Angeles Air Force Base.
The improvement is created by Boeing's new Wideband Digital Channelizer, a feature that will be included in the final three satellites in the series.
The channelizer is the heart of the satellite's communications package.

WGS uses the Boeing 702HP satellite design, which includes a xenon-ion propulsion system, highly efficient triple-junction gallium arsenide solar cells and deployable radiators with flexible heat pipes.
The WGS satellites serve as the backbone of the DOD communications infrastructure, suppling data to the battlefield, relaying video from unmanned aerial reconnaissance drones, routing voice calls and data messaging, and even offering quality-of-life considerations like television broadcasts and email delivery to the troops.
Worldwide coverage is provided by the WGS spacecraft constellation. Each craft provides shaped, steerable spotbeams of bandwidth wherever requested across its field-of-view for X- and Ka-band frequencies, plus the onboard capability to switch signals from one band to the other.
X-band communications allow data, photos and video to be relayed to troops and Ka-band enables high-volume broadcasting to user terminals across the reception area.
The exact location in the geosynchronous belt for WGS 8 has not been revealed. The satellite's mission will further bolster the overall system's capacity.
"WGS 8 is the continued expansion of the WGS constellation," Sejba said.
WGS also supports several allied nations — Australia, Canada, Denmark, the Netherlands, Luxembourg and New Zealand. The countries have contributed to buying two of the satellites in the series in exchange for access to the constellation.
WGS 8 arrived in Florida from the Boeing factory in El Segundo, California, on Oct. 12 aboard an Air Force C-17 transport aircraft. It was the first national security satellite to land at the Space Coast Regional Airport in Titusville.
The Delta 4 vehicle launching WGS 8 will fly in the powerful Medium+(5,4) configuration with a five-meter upper stage and payload fairing and the four solids. ULA rockets have deployed the entire WGS constellation, with the final two craft scheduled in the next two years aboard Delta.
It will be the 376th Delta rocket launch since 1960, the 34th Delta 4 rocket since debuting in 2002 and the sixth time a Delta has launched a WGS communications satellite.
In other Cape Canaveral launch news, officials have tentatively set Nov. 16 as the new target date for the Atlas 5 rocket to deploy the GOES-R weather satellite. The two-hour launch window will open at 4:42 p.m. EST (2142 GMT).

Rocket/Payload: A United Launch Alliance Delta IV Medium+ (5,4) configuration will launch the eighth Wideband Global SATCOM (WGS-8 ) mission for the U.S. Air Force.

Date/Site/Launch Time: Wednesday, Dec. 7, 2016, from Space Launch Complex-37 at Cape Canaveral Air Force Station, Florida.

Mission Description: WGS satellites are important elements of a high-capacity satellite communications system providing enhanced communications capabilities to America's troops in the field for the next decade and beyond. WGS enables more robust and flexible execution of Command and Control, Communications Computers, Intelligence, Surveillance, and Reconnaissance (C4ISR), as well as battle management and combat support information functions. The WGS constellation augments the existing service available through the UHF Follow-on satellite by providing enhanced information broadcast capabilities.

Launch Notes: WGS-8 will mark ULA's 70th national security launch since the company was founded in 2006. This is the sixth flight in the Medium+ (5,4) configuration; all launches in this configuration were WGS missions.

CAPE CANAVERAL — The next satellite to launch fr om Cape Canaveral — an essential communications satellite for the U.S. military and allied nations — was moved to the pad and mounted atop its Delta 4 rocket today.
The eighth Wideband Global SATCOM spacecraft will be boosted into a super-synchronous transfer orbit more than 41,000 statute miles high by the Delta 4 Medium+ (5,4) configured rocket with four strap-on solids.
Liftoff is planned for Dec. 7 during a window of 6:53 to 7:42 p.m. EST (2353-0042 GMT).
WGS is the Department of Defense's highest capacity communications satellite system. The spacecraft create a global constellation to provide the needed coverage and connectivity in support of operations by U.S. and allied forces around the world.
Boeing builds the WGS satellites, which began launching in 2007.
The new bird, valued at $426 million, will be maneuvered into a circular geosynchronous orbit 22,300 miles above the equator to enter serviced from an undisclosed position.
It carries the first Wideband Digital Channelizer at the heart of its communications package, enabling a 90 percent improvement in available bandwidth compared previous WGS satellites.
WGS supports all branches of the U.S. military, plus Australia, Canada, Denmark, the Netherlands, Luxembourg and New Zealand. The international partners have paid for two of the 10 satellites in the series in exchange for access to the entire constellation.
Already shrouded in the rocket's 47-foot-tall, 17-foot-diameter composite nose cone, the WGS 8 spacecraft was hauled to Complex 37 overnight and hoisted atop the Delta 4 launch vehicle today.
The fully assembled rocket stands 217 feet tall.
The satellite was flown to Florida on Oct. 12 from Boeing's manufacturing facility in El Segundo, California. After arriving, it was taken to the commercial Astrotech processing facility to undergo pre-flight preps.
Final testing, loading of maneuvering propellant and encapsulation in the Delta 4's nose cone was accomplished with the satellite.
Today's transfer to the pad saw the 13,000-pound satellite move from Titusville, through the Kennedy Space Center and over to Cape Canaveral Air Force Station's Complex 37 wh ere the Delta has undergo attachment of the four solid boosters, a fueling exercise and pre-launch testing since rolling from its hangar a month ago.
This will be the fourth and final Delta rocket launch of 2016.

Launch minus 20 minutes! United Launch Alliance's Delta 4 has been a workhorse for U.S. military and national security spacecraft since entering service in 2002.
The vehicle stands 217 feet tall, weighs about 900,000 pounds fully fueled and will unleash 1.8 million pounds of thrust at launch.
The rocket comes off the pad powered by an Aerojet Rocketdyne RS-68A engine on the Common Booster Core first stage and four Orbital ATK GEM-60 solid rocket boosters.
The throttleable RS-68A engine burns liquid hydrogen and liquid oxygen to produce 702,000 pounds of thrust. The stage measures 155 feet in length with interstage permanently attached, 16.7 feet in diameter and is covered in orange insulating foam.
The Graphite Epoxy Motor (GEM) series originated with the GEM-40 motor that was developed for the Delta 2 rocket a quarter-century ago. Cases are filament wound by computer-controlled winding machines using high-strength graphite fiber and durable epoxy resin. The "60" indicates the diameter in inches. Each GEM-60 produces a maximum of 280,000 pounds of thrust.
The cryogenic upper stage also burns liquid hydrogen and liquid oxygen to power its single Aerojet Rocketdyne RL10B-2 engine for 24,750 pounds of thrust. It features a cone-shaped carbon-carbon extendible nozzle that is 7 feet in diameter.

T+plus 41 minutes, 46 seconds. SPACECRAFT SEPARATION! The Wideband Global SATCOM 8 military communications satellite has been deployed into orbit from the Delta 4 rocket's upper stage, completing tonight's launch.

Liftoff occurred on-time and the flight appeared nominal.

The WGS 8 spacecraft will spend the next three months being maneuvered into a circular geosynchronous orbit by controllers at Boeing's satellite facility in El Segundo, California. The orbit raising activities will use both the conventional propellant engines as well as ion propulsion thrusters.

Boeing will oversee the craft's solar array and antenna deployments, plus complete an initial round of testing before WGS 8 is handed over to the Air Force.

ЦитироватьВАШИНГТОН, 8 дек — РИА Новости. Ракета Delta IV со спутником широкополосной связи WGS-8 (Wideband Global SATCOM 8) для ВС США стартовала с космодрома на мысе Канаверал (штат Флорида), трансляцию запуска ведет компания United Launch Alliance.

Старт ракеты был дан в расчётные 2.53 мск. Ракета выводит на геостационарную орбиту восьмой аппарат в широкополосной глобальной спутниковой системе связи WGS.

Спутники WGS предназначены для высокоскоростной передачи защищенных сигналов и информации между центральным командованием, американскими военными судами, подводным флотом, наземными войсками.

Система WGS должна заменить действующую систему DSCS, будет состоять из 10 аппаратов. Первый спутник серии WGS был запущен в 2007 году.
