August 22, 2019Stephen Clark

The last Delta 4-Medium rocket lifted off from Cape Canaveral Thursday with a GPS navigation satellite for the U.S. Air Force.

The 207-foot-tall (63-meter) rocket launched from pad 37 at 9:06 a.m. EDT (1306 GMT), powered by a hydrogen-fueled RS-68A main engine and two strap-on solid rocket boosters producing more than 1.2 million pounds of thrust.

The engine and booster nozzles vectored their thrust to steer the Delta 4 rocket northeast from Cape Canaveral, aligning its trajectory with one of six orbital planes in the GPS navigation satellite network some 12,550 miles (20,200 kilometers) above Earth.

Thursday's launch was the 40th flight of a Delta 4 rocket since November 2002, and the 29th and final mission to use one of ULA's Delta 4-Medium variants, which use a single first stage core. At least five more launches by ULA's Delta 4-Heavy rocket, made of three Delta 4 first stage booster cores, are planned through late 2023.

T+plus 1 hour, 49 minutes. After the completion of the primary mission today by deploying the payload, the second stage will perform a third and final burn. Engine start is expected in about 30 minutes. This brief, 15-second firing will serve as a de-orbit burn by lowering the rocket body's perigee for disposal into the atmosphere at the end of this revolution of the globe, which will occur about five hours from now. The disposal guards against unnecessary space debris.

GPS 3 SV02 separation confirmed! The U.S. Air Force's GPS navigation network has a new member after today's successful launch aboard a United Launch Alliance Delta 4 rocket.

The 8,170-pound (3,705-kilogram) GPS 3 SV02 spacecraft is dubbed "Magellan," after the Portuguese explorer Ferdinand Magellan. It's the second in a new block of GPS 3-series satellite made by Lockheed Martin, providing higher-power and more accurate navigation signals for military and civilian users around the world.

The GPS 3 SV02 spacecraft will use its own propulsion system to reach a circular orbit some 12,550 miles (20,200 kilometers) above Earth, where it will join more than 30 other satellites currently broadcasting positioning, navigation and timing signals.

With today's launch, the Delta 4-Medium rocket family logged 29 missions in its career, beginning with the debut Delta 4 launch Nov. 20, 2002. All 29 of the Delta 4-Medium missions were successful, giving the rocket an unblemished record.

Today's mission marked the final flight of the GEM-60 strap-on solid rocket motors built by Northrop Grumman Innovation Systems. Northrop Grumman derived the GEM-60 booster from the smaller GEM-40 and GEM-46 motors that flew on the Delta 2 and Delta 3 rockets.

A larger solid rocket booster named the GEM-63 will begin flying on Atlas 5 rockets next year, replacing boosters currently made by Aerojet Rocketdyne. A variant of the GEM-63 solid rocket motor will also fly on ULA's next-generation Vulcan Centaur rocket.

The quick-look

The traditional quick-look post-flight data review of today's mission has occurred at the Delta Operations Center following the successful flight by the United Launch Alliance Delta IV rocket.

Today's launch represents the 135th successful mission for United Launch Alliance and the 71st Global Positioning System satellite delivered into orbit by ULA and our heritage rockets. This flight also marked the 40th mission for the Delta IV and the final flight of the Medium variant.

Liftoff occurred at 9:06:00.167 a.m. EDT with southeasterly winds at 5 knots and a temperature of 86 degrees F.

Engineers representing various launch vehicle elements offered brief synopses of system performance -- such as the engines, hydraulics and avionics. The vehicle performed nominally during its mission and injected the GPS III SV02 payload into the proper orbit.

The quick-look meeting received congratulatory speeches from company leadership and the customer. ULA officials expressed appreciation to the Air Force in being entrusted in launching this national asset.

The Delta IV Medium vehicle retires with a 100 percent mission success record in its 17 years of launches. Today's mission was the final use of the single-core Delta IV configuration as we transition to our future Vulcan Centaur rocket that will provide an affordable, higher performance launch service for our customers.

ЦитироватьUnited Launch Alliance Successfully Launches GPS III Satellite for U.S. Air Force Space and Missile Systems Center

Cape Canaveral Air Force Station, Fla., (Aug. 22, 2019) – A United Launch Alliance (ULA) Delta IV rocket carrying the second Global Positioning System III (GPS III) satellite, designated Magellan, for the U.S. Air Force Space and Missile Systems Center lifted off from Space Launch Complex-37 on August 22 at 9:06 EDT. This mission marked the 29th and final flight of the Delta IV Medium rocket and the 73rd GPS launch by a ULA or heritage vehicle.

"Thank you to the team and our mission partners for the tremendous teamwork as we processed and launched this critical asset, providing advanced capabilities for warfighters, civil users, and humankind across the globe," said Gary Wentz, ULA vice president of Government and Commercial Programs. "We are proud of the strong legacy of the Delta IV Medium program, and look forward to the future with our purpose-built Vulcan Centaur."

The GPS III system, built by Lockheed Martin, represents the next step in modernization of the worldwide navigation network with a new generation of advanced satellites offering improved accuracy, better anti-jam resiliency and a new signal for civil users.

This mission launched aboard a Delta IV Medium+ (4,2) configuration vehicle, which included a 4-meter Payload Fairing and two Northrop Grumman solid rocket motors. The common booster core for Delta IV was powered by the RS-68A engine, and the Delta Cryogenic Second Stage was powered by the RL10B-2 engine, both supplied by Aerojet Rocketdyne.

ULA's next launch is Boeing's CST-100 Starliner, Orbital Flight Test, aboard an Atlas V rocket from Space Launch Complex-41 at Cape Canaveral Air Force Station, Fla.

ULA maintains a track record of 100% mission success with 135 successful launches.

With more than a century of combined heritage, ULA is the world's most experienced and reliable launch service provider. ULA has successfully delivered more than 130 satellites to orbit that provide Earth observation capabilities, enable global communications, unlock the mysteries of our solar system, and support life-saving technology.

Компания ULA запустила навигационный спутник для ВВС США

Это последний пуск Delta IV в конфигурации Medium+

НЬЮ-ЙОРК, 22 августа. /ТАСС/. Американская компания United Launch Alliance (ULA) в четверг запустила и доставила на заданную орбиту навигационный спутник GPS третьего поколения. Старт ракеты-носителя Delta IV с базы ВВС США на мысе Канаверал (штат Флорида) состоялся в 09:06 по времени Восточного побережья (16:06 мск).

"Ракета Delta IV United Launch Alliance высвободила на заданной орбите спутник GPS-3 SV02 Magellan, предназначенный для улучшения качества военной навигации и расширения возможностей гражданского назначения", - отметила в своем Twitter компания.

Отделение первой ступени носителя произошло через 4 минуты и 30 секунд после пуска. Вторая ступень ракеты достигла назначенной орбиты через 1 час 14 минут после старта. Эту ступень предполагается через пять часов уничтожить в плотных слоях атмосферы. Трансляция полета на сайте United Launch Alliance была ранее прервана ввиду секретности миссии.

До этого отправку в космос данного аппарата, собранного компанией Lockheed Martin, откладывали не меньше четырех раз.

Запуск первого из навигационных спутников GPS третьего поколения для нужд ВВС США был осуществлен в декабре 2018 года компанией SpaceX. Она отмечала, что аппарат разработан для "передачи информации о расположении, навигации и времени" в три раза точнее и при обеспечении "в восемь раз более высокой помехоустойчивости". Это 29-й по счету и последний пуск Delta IV в конфигурации Medium+, а также 135-я миссия United Launch Alliance.

ULA была основана в 2006 году. Ее штаб-квартира расположена в городе Сентенниал (штат Колорадо). Компания является совместным предприятием американских авиастроительных корпораций Boeing и Lockheed Martin.
