ULA's really nice touch of dedications for team members who have passed on. Michael Carr's name, just above the venting.

Today's lucky passenger is the 8 Ball. Oh and for those watching the webcast, there will be a test (with prizes!)

T+plus 5 minutes, 20 seconds. Delta is 145 miles in altitude, traveling over 10,000 mph.

12/08/2016 01:57
T+plus 4 minutes, 23 seconds. Engine start! The cryogenic RL10B-2 upper stage engine has ignited for the first of two burns during the launch sequence, this one to reach a preliminary parking orbit!

12/08/2016 01:56
T+plus 4 minutes, 5 seconds. The Common Booster Core first stage and the attached interstage have been separated in one piece from the Delta 4's upper stage. The upper stage engine's extendible nozzle is dropping into position.

12/08/2016 01:56
T+plus 3 minutes, 57 seconds. BECO! Booster engine cutoff confirmed as the Aerojet Rocketdyne RS-68A powerplant shuts down.

12/08/2016 01:56
T+plus 3 minutes, 51 seconds. The main engine is throttling down to its minimum power setting in preparation for shutdown.

12/08/2016 01:56  View of solid rocket motor separation


12/08/2016 01:56
T+plus 3 minutes, 17 seconds. Now above the discernible atmosphere, the protective nose cone enclosing the WGS 8 satellite atop the rocket has jettisoned.

12/08/2016 01:55
T+plus 3 minutes, 5 seconds. Passing Mach 10.

12/08/2016 01:55
T+plus 3 minutes. The main engine continues to perform well, consuming its liquid hydrogen and liquid oxygen propellants.

12/08/2016 01:55
T+plus 2 minutes, 30 seconds. The RS-68A is consuming nearly a ton of propellants per second as the powerplant pushes the Delta 4 rocket closer to the edge of space. 

12/08/2016 01:55
T+plus 2 minutes, 10 seconds. Mach 5. 

12/08/2016 01:54
T+plus 2 minutes. The vehicle weighs half of what it did at liftoff.

12/08/2016 01:54
T+plus 1 minute, 45 seconds. Solid motor separation! The spent boosters have been shed from the first stage. Delta 4 continues powering its way toward space on the thrust generated by the RS-68A main engine.

12/08/2016 01:54
T+plus 1 minute, 35 seconds. The four Orbital ATK solid rocket boosters have burned out of their propellant. Standing by for jettison.

12/08/2016 01:54  Delta 4 roars into the night


12/08/2016 01:53
T+plus 60 seconds into flight of Delta 376 and the eighth WGS spacecraft.

12/08/2016 01:53
T+plus 47 seconds. Now passing through the region of maximum aerodynamic pressure.

12/08/2016 01:53
T+plus 36 seconds. The launcher has broken through the sound barrier.

12/08/2016 01:53
T+plus 30 seconds. The Delta 4 rocket is climbing away from Cape Canaveral with its main engine firing at full throttle and the four strap-on boosters giving a powerful extra kick.

12/08/2016 01:52  LAUNCH
LIFTOFF! Liftoff of the Delta 4 rocket and the WGS 8 spacecraft, launching the highest capacity U.S. military communications satellite ever made!

12/08/2016 02:01
T+plus 8 minutes, 15 seconds. Trajectory right on target.

12/08/2016 02:00
T+plus 7 minutes, 30 seconds. Delta is 205 miles in altitude and 870 miles east of the launch pad.

12/08/2016 01:59
T+plus 7 minutes. Still looking good as Delta arcs over the Atlantic.

12/08/2016 01:59
T+plus 6 minutes, 30 seconds. RL10 is burning well.

T+plus 10 minutes. The upper stage is the larger five-meter version that has flown previously on the Delta 4-Heavy vehicle, WGS missions and two National Reconnaissance Office launches. It is an element that distinguishes this Medium+ (5,4) rocket configuration from other variants use four-meter upper stages for lower-weight payloads.
Today's stage has a wider liquid hydrogen tank and a lengthened liquid oxygen tank to carry additional propellants, enabling the RL10 engine to fire longer and carry heftier cargos.

12/08/2016 02:04
T+plus 11 minutes, 45 seconds. The vehicle's steep climb leveled off as it gains speed toward orbital velocity.

12/08/2016 02:04
T+plus 11 minutes, 30 seconds. The RL10 engine is burning a mixture of liquid oxygen and liquid hydrogen cryogenic propellants.

12/08/2016 02:03
T+plus 10 minutes, 45 seconds. Delta is 236 miles in altitude and 1,500 miles east of the launch pad, tateveling at 12,300 mph.

12/08/2016 02:05
T+plus 12 minutes, 30 seconds. The RL10 engine is burning well. Chamber pressure still looks good.

[Salo]

12/08/2016 02:07
T+plus 14 minutes. Still going smoothly aboard the Delta 4.

[Salo]

12/08/2016 02:09
T+plus 16 minutes. About four minutes remain in this firing of the second stage. Good chamber pressure, stable body rates.

[Salo]

12/08/2016 02:10
T+plus 18 minutes. The upper stage's the RL10 engine working well, still firing as planned to reach the parking orbit this evening.

12/08/2016 02:10
T+plus 17 minutes, 30 seconds. This burn will obtain orbital velocity and place the vehicle into an initial parking orbit around Earth.

[Salo]

12/08/2016 02:11
T+plus 19 minutes. The second stage engine continues to fire well with good chamber pressure. All is reported normal.

[Salo]

12/08/2016 02:12  Main Engine Cut Off No. 1
T+plus 19 minutes, 47 seconds. MECO 1. Confirmation that the upper stage main engine has shut down after the first of two planned firings to inject the WGS 8 spacecraft into a super-synchronous transfer orbit.

Опорная орбита!
