SPACEFLIGHT NOW
Posted: July 28, 2010

T-00:02.7    Engine Start
The Russian-designed RD-180 main engine is ignited and undergoes checkout prior to launch.

T+00:01.1    Liftoff
The three strap-on solid rocket boosters are lit as the Atlas 5 vehicle, designated AV-019, lifts off and begins a vertical rise away from Complex 41 at Cape Canaveral Air Force Station, Florida.

T+01:56    Jettison SRBs
Having burned out of propellant approximately 25 seconds earlier, the spent solid rocket boosters are jettisoned to fall into the Atlantic Ocean.

T+03:27    Nose Cone Jettison
The payload fairing that protected the AEHF 1 spacecraft during launch is separated once heating levels drop to predetermined limits.

T+03:33    Forward Load Reactor Jettison
The Forward Load Reactor deck that supported the payload fairing's structure to Centaur upper stage is released six seconds after the shroud's jettison.

T+04:17    Main Engine Cutoff
The RD-180 main engine completes its firing after consuming its kerosene and liquid oxygen fuel supply in the Atlas first stage.

T+04:23    Stage Separation
The Common Core Booster first stage of the Atlas 5 rocket separates from the Centaur upper stage. Over the next few seconds, the Centaur engine liquid hydrogen and liquid oxygen systems are readied for ignition.

T+04:33    Centaur Ignition 1
The Centaur RL10 engine ignites for the longer of the two upper stage firings. This burn will inject the Centaur stage and AEHF 1 spacecraft into a parking orbit.

T+14:08    Centaur Cutoff 1
The Centaur engine shuts down after arriving in a planned parking orbit. The vehicle enters a brief coast period lasting nearly 8 minutes before arriving at the required location in space for the second burn.

T+22:17    Centaur Ignition 2
The Centaur re-ignites over the equatorial Atlantic to accelerate the payload into geosynchronous transfer orbit from the parking achieved earlier in the launch sequence.

T+27:37    Centaur Cutoff 2
At the conclusion of its second firing, the Centaur will have delivered the AEHF 1 spacecraft into the targeted orbit with an apogee of 22,236 statute miles, perigee of 119 statute miles and inclination of 27 degrees.

T+51:00    Spacecraft Separation
The U.S. military's first Advanced Extremely High Frequency communications satellite is released into orbit from the Centaur upper stage to complete the AV-019 launch.

"Our number one priority is delivering mission success for our customer," said Mike Davis, Lockheed Martin's AEHF vice president. "The AEHF system will vastly improve battlefield communications, delivering secure, real-time, connectivity to a greater number of forces in the field, and their commanders anywhere on the globe. We look forward to successfully executing the next steps necessary to making this national asset operational for the warfighter."

"We are proud to be part of the U.S. Air Force and Lockheed Martin team that has worked so hard to launch this capability vital to our warfighters," said Stuart Linsky, vice president, Protected SatCom Programs, for Northrop Grumman's Aerospace Systems sector.

1220 GMT (8:20 a.m. EDT)
"This morning's successful launch is testimony to the dedication, skill and operational excellence of the entire government-industry AEHF team," said Col. Michael Sarchet, commander of the Protected Satellite Communications Group at the Air Force's Space and Missile Systems Center.

"For over 15 years, the Milstar constellation has served as the backbone of secure military communications, helping the military operate in a secure mode without concern of enemy interference. AEHF will significantly enhance our national security space architecture, and we eagerly anticipate providing this new capability to the warfighter."

1214 GMT (8:14 a.m. EDT)
Ground controllers are communicating with the AEHF 1 spacecraft and all systems are reported in good shape following the satellite's successful trip into orbit.

1201 GMT (8:01 a.m. EDT)
The next Atlas launch is scheduled for September 20 from Vandenberg Air Force Base in California. That flight will deploy a classified spy satellite payload for the National Reconnaissance Office.

1200 GMT (8:00 a.m. EDT)
"ULA is proud to have played an important role in the successful launch of the first of three AEHF satellites for this critical constellation that will directly support the warfighter on the battlefield," said Jim Sponnick, United Launch Alliance's vice president for Mission Operations.

"This was a tremendous launch campaign highlighted by close teamwork between the U.S. Air Force, the ULA launch team and our many mission partners that made today's successful launch possible. We look forward to launching AEHF 2 in 2011."

1158 GMT (7:58 a.m. EDT)

ЦитироватьUnited Launch Alliance Atlas V Successfully Launches First AEHF Mission[/size]
 

CAPE CANAVERAL AIR FORCE STATION, Fla., Aug. 14 /PRNewswire/ -- A United Launch Alliance Atlas V rocket successfully launched the Advanced Extremely High Frequency-1 (AEHF-1) satellite for the Air Force at 7:07 a.m. EDT today from Space Launch Complex- 41.  The AEHF constellation of four satellites will provide 10 times greater capacity and channel data rates six times higher than that of the existing Milstar II communications satellites. AEHF-1 will be joined by the next two AEHF satellites to be launched during the next two years by ULA.

This launch marks the fifth mission overall and third Atlas V mission for ULA in 2010.  AEHF-1 represents the latest "one-at-a-time" mission success which has been accomplished 43 times since ULA was formed on Dec. 1, 2006.

"ULA is proud to have played an important role in the successful launch of the first of three AEHF satellites for this critical constellation that will directly support the war fighter on the battlefield," said Jim Sponnick, ULA vice president, Mission Operations.  "This was a tremendous launch campaign highlighted by close teamwork between the U.S. Air Force, the ULA launch team and our many mission partners that made today's successful launch possible. We look forward to launching AEHF-2 in 2011."

This mission was launched aboard an Atlas V 531 launch vehicle configuration. The mission used an Atlas V common core booster powered by the RD AMROSS RD-180 engine, three Aerojet solid rocket motors, a Pratt & Whitney Rocketdyne RL10A upper stage engine and a 5.4-meter diameter Ruag composite payload fairing.

ULA's next launch, currently scheduled for Sept. 20, is an Atlas V from Space Launch Complex-3 at Vandenberg Air Force Base, Calif.  It is a National Reconnaissance Office mission in support of national defense.

ULA program management, engineering, test and mission support functions are headquartered in Denver, Colo. Manufacturing, assembly and integration operations are located at Decatur, Ala., Harlingen, Texas, San Diego, Calif., and Denver, Colo.  Launch operations are located at Cape Canaveral Air Force Station, Fla., and Vandenberg Air Force Base, Calif.

For more information on the ULA joint venture, visit the ULA Web site at www.ulalaunch.com, or call the ULA Launch Hotline at 1-877-ULA-4321 (852-4321).

ЦитироватьВ США запущен новый военный спутник

(07:58 ) 16.08.2010

В минувшую субботу в США был произведен запуск нового военного спутника. Ракета Atlas V, созданная в United Launch Alliance, запустила на орбиту вокруг нашей планеты новый аппарат AEHF-1 или Advanced Extremely High Frequency - 1. Согласно полученным данным, старт состоялся с 41-й стартовой площадки ВВС США на космодроме на мысе Канаверал во Флориде. Старт прошел в 15:07 мск, 14 августа. Военные называют минувший запуск "полностью успешным".

Новые спутники семейства AEHF должны будут в будущем заменить группировку аппаратов Milstar. Предназначены они для организации коммуникаций между военными. Поддерживаются как голосовые системы связи, так и защищенные системы передачи данных. Кроме того, у новых спутников есть обновленная система защиты от подавления сигнала.

Разработчики аппарата говорят, что AEHF позволят поддерживать связь между президентом страны и военными даже в случае ядерного удара по США.

Основным подрядчиком при изготовлении аппаратов этой серии стала американская Lockheed Martin, эта же компания предоставила и наземную инфраструктуру для управления спутниками.

Известно также, что кроме США в ограниченном режиме этими аппаратами будут пользоваться Нидерланды, Канада и Великобритания. Когда группировка спутников AEHF будет завершена, то она будет состоять из рабочих и резервных аппаратов. Кроме  коммуникационных возможностей, новые аппараты также обладают возможностями наведения на цель, передачи "живого" видео и ограниченными возможностями картографии.
