Launch of US Air Force's Mini Space Shuttle - X-37B on Atlas V Rocket

An American Atlas V rocket in the 501 configuration has successfully lifted off from Space Launch Complex 41 at Cape Canaveral carrying the US Air Force's X-37B spaceplane, a smaller version of the Space Shuttle. This will be the fourth mission of the X-37B which conducts top secret missions in orbit via payloads in it's payload bay. Liftoff occurred at 11:05 Local time, 15:05 UTC time on May 20th 2015.

1510 GMT (11:10 a.m. EDT)
 And with that, the launch will go under a veil of secrecy. Confirmation that the Orbital Test Vehicle has arrived in space or separated from the Centaur won't be announced live.
 
1509 GMT (11:09 a.m. EDT)
 T+plus 4 minutes, 44 seconds. Centaur has ignited! The RL10 engine is up and running at full thrust for its firing to propel X-37B to orbit.
 
1509 GMT (11:09 a.m. EDT)
 T+plus 4 minutes, 33 seconds. The Atlas 5's Common Core Booster first stage has been jettisoned, and the Centaur upper stage's liquid hydrogen and liquid oxygen systems are being readied for engine start.
 
1509 GMT (11:09 a.m. EDT)
 T+plus 4 minutes, 25 seconds. BECO. Booster Engine Cutoff is confirmed as the RD-180 powerplant on the first stage completes its burn. Standing by to fire the retro thrusters and separate the spent stage.
 
1508 GMT (11:08 a.m. EDT)
 T+plus 3 minutes, 50 seconds. The two-halves of the Atlas 5 rocket nose cone encapsulating the X-37B spaceplane have separated. The Orbital Test Vehicle is now exposed to space. Also jettisoned was the Forward Load Reactor, a two-piece deck that rings the Centaur stage to support the bulbous fairing during launch.
 
1508 GMT (11:08 a.m. EDT)
 T+plus 3 minutes, 20 seconds. RD-180 is performing well as the rocket climbs away from the planet.
 
1507 GMT (11:07 a.m. EDT)
 T+plus 2 minutes, 30 seconds. The vehicle now weighs half of what it did at liftoff. Everything still looking good.
 
1507 GMT (11:07 a.m. EDT)
 T+plus 2 minutes. The RD-180 main engine continues to fire normally, burning a mixture of highly refined kerosene and liquid oxygen.
 
1506 GMT (11:06 a.m. EDT)
 T+plus 105 seconds. The engine throttle setting is easing back to 95 percent thrust.
 
1506 GMT (11:06 a.m. EDT)
 T+plus 90 seconds. Mach 1.
 
1506 GMT (11:06 a.m. EDT)
 T+plus 60 seconds. One minute into the ascent as the Atlas 5 climbs away from the Cape, the X-37B spaceplane riding inside the nose cone en route to orbit.
 
1505 GMT (11:05 a.m. EDT)
 T+plus 45 seconds. Good engine performance.
 
1505 GMT (11:05 a.m. EDT)
 T+plus 30 seconds. The vehicle is thundering away from Cape Canaveral's Complex 41 on 860,000 pounds of thrust from the RD-180 main engine.
 
1505 GMT (11:05 a.m. EDT)
 LIFTOFF! Liftoff of the Atlas 5 rocket with the X-37B mini shuttle for its fourth trip to space. And the tower is clear!

Тяжело как-то пошла вначале, или показалось?

Почему-то время пуска получается 18:05:05 ДМВ.

Очень тяжело без ТТУ. Видимо на грани для данного варианта РН.

Ну а кубосаты то выпустили ?   Солнечный парус развернули ?

Попутного ветра в паруса, и 700 тысяч футов под килем.

Все 10 кубсатов на орбите.

ULA has confirmed successful deployment of 10 CubeSats hitching ride on Atlas V's Centaur stage, including @exploreplanets' LightSail.

Early take on data: mostly nominal. Batteries and temps close to expected ranges. Tumble rates X, Y, Z: -7, -0.1, -0.3 deg/sec. #LightSail

Очень необычно: голливудский пафос насчет секретности - и внезапно 10 штук каких-то левых кубсатов! Что-то не верится, чтобы наши военные пустили свой аппарат с попутной гражданской нагрузкой.

Если есть возможность взять дополнительную нагрузку - почему нет ? Лишний пиар USAF не помешает - помогли студентам приблизиться к космосу. Зато у нас начали бы надувать щёки - а вдруг, а зачем, а если, а может не надо...

[triage]

кажется там не 10 левых кубосатов, 4 из 10 от военных структур - pdf на второй странице темы
