Meet the rocket launching today: #DeltaIVHeavy. It is the only rocket in the world today that meets all of the requirements to perform this #NROL82 mission for @NatReconOfc and @SpaceForceDoD. #PartnersinSpace

ULA  @ulalaunch
If you are just tuning in, the countdown is proceeding toward a liftoff of #DeltaIVHeavy at 1:47pmPDT (4:47pmEDT; 2047 UTC). We continue to have a green board with no issues being worked. The launch webcast begins at L-20 minutes: http://bit.ly/div_nrol82

The countdown is entering the 31-minute built-in hold at T-minus 4 minutes. The final readiness polls will be performed during this hold before permission is given to launch. Liftoff time remains targeted for 1:47pmPDT (4:47pmEDT; 2047 UTC). http://bit.ly/div_nrol82

Получасовое зависание на четырёх-минутной готовности.

ULA  @ulalaunch
#DeltaIVHeavy will lift off on 2.1 million pounds of thrust from its three main engines. The port and starboard common booster cores burn for four minutes, while the center core fires for an additional 90 seconds before staging and ignition of the second stage.

ULA  @ulalaunch
L-10 minutes from launch. The space asset being launched is a payload designed, built and operated by the @NatReconOfc that supports the agency's national security mission to provide intelligence data to senior policy makers, the Intelligence Community and Department of Defense.

#DeltaIVHeavy is traveling five times the speed of sound now with less than a minute of burn time left in the port and starboard boosters. http://bit.ly/div_nrol82

[zandr]

ULA  @ulalaunch
Separation of the port and starboard boosters is confirmed, and the center core has throttled up to full power to consume the fuel conserved by burning at lower thrust for the past four minutes. Velocity nearly doubles in this phase of flight. http://bit.ly/div_nrol82

Да. Редкая Дельта с первого раза улетает 

[Чебурашка]

Ну как обычно. До сброса обтекателя. Дальше кина не будет 

[Liss]

Хорошо ушла, аккуратно. 
Интересно, зачем столько разворотов по крену.

ULA  @ulalaunch
#DeltaIVHeavy's composite payload fairing that protected #NROL82 during ascent through the atmosphere has jettisoned at the edge of space. The rocket now weighs just seven percent of its liftoff mass. http://bit.ly/div_nrol82

Spaceflight Now  @SpaceflightNow
The Delta 4's center engine has shut down and the core booster has separated.
The second stage's RL10 engine has ignited for its first burn, and ULA says the rocket's payload shroud has jettisoned.

A United Launch Alliance Delta 4-Heavy rocket climbed into orbit Monday from a military base in California, hauling to space a classified spy satellite as large as a bus & leaving just three Delta rockets left to fly before retirement.
