Now in parking orbit. Looks like 185 x 6078 km x 27.60 deg

Long first burn of the second stage; expected parking orbit apogee around 6800 km

Beautiful launch of the #WGS8 by @ulalaunch atop the #DeltaIV rocket at 6:53pm (ET), seen here from @ExploreSpaceKSC

Now coasting to equator before restart to raise apogee further - much further

Now 12 minutes to planned spacecraft separation, @lorengrush you are allowed to go eat then

T+plus 32 minutes, 38 seconds. MECO 2. The second of two firings by the upper stage during today's launch has been completed, ending the powered phase of flight.

12/08/2016 02:24
T+plus 31 minutes, 30 seconds. This burn injects the rocket into a highly elliptical orbit stretching about 24,000 nautical miles in altitude at its furthest point from Earth, slightly higher than  standard for a dropoff point for satellites headed into geostationary orbit. This will allow WGS 8 to save some of its fuel.

12/08/2016 02:23
T+plus 30 minutes, 15 seconds. This burn will last just over three minutes in duration.

12/08/2016 02:22  Main Engine Start No. 2
T+plus 29 minutes, 28 seconds. Ignition! The RL10B-2 engine, fed by liquid hydrogen and liquid oxygen, has been started once again! This firing will propel WGS 8 to its desired orbit.

T+plus 27 minutes. Things are still looking good, no reports of any issues tonight following an on-time liftoff.

12/08/2016 02:19
T+plus 26 minutes, 30 seconds. The vehicle continues in the coast mode before the next firing of the upper stage engine. Re-ignition of the RL10 engine is three minutes away.

12/08/2016 02:16
T+plus 23 minutes. Officials confirm that the Delta 4 rocket has successfully reached its targeted orbit of approximately 100 by about 3,300 nautical miles with an inclination of 27.6 degrees.

SECO 2. #WGS8 lofted into a super-synchronous transfer orbit by the second burn of Delta 4's upper stage.

Injection for #WGS8 was into a lower orbit than previous WGS satellites to save fuel on the second stage for a deorbit maneuver.

Delta 4 second stage now in 430 x 44207 km x 27.0 deg supersync transfer orbit

T+plus 39 minutes. The rocket is coasting in orbit and will soon deploy the next Wideband Global SATCOM, continuing the modernization effort for the U.S. military's satellite communications network in space.

T+plus 36 minutes. The Delta 4 rocket has successfully reached its targeted super-synchronous transfer orbit, ULA says.

12/08/2016 02:34  WGS 8 DEPLOYED!

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.

С космодрома США стартовала ракета с коммуникационным спутником

ВАШИНГТОН, 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.
