T-minus 2 minutes and counting. Still GO for launch of the Delta rocket.

03/19/2017 03:15
T-minus 2 minutes, 30 seconds. The liquid oxygen tank in the Common Booster Core first stage is confirmed at the proper level and pressure for flight.

T+plus 4 minutes, 20 seconds. Engine start! The cryogenic RL10B-2 upper stage engine has ignited for the first of two burns during the launch sequence to loft WGS 9, this one to reach a preliminary parking orbit!

03/19/2017 03:21
T+plus 4 minutes, 7 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.

T+plus 3 minutes, 58 seconds. BECO! Booster engine cutoff confirmed as the Aerojet Rocketdyne RS-68A powerplant shuts down.

03/19/2017 03:21
T+plus 3 minutes, 51 seconds. The main engine is throttling down to its minimum power setting in preparation for shutdown.

03/19/2017 03:21
T+plus 3 minutes, 20 seconds. Now above the discernible atmosphere, the protective nose cone enclosing the WGS 9 satellite atop the rocket has jettisoned.

T+plus 3 minutes, 5 seconds. Passing Mach 10.

03/19/2017 03:20
T+plus 3 minutes. The main engine continues to perform well, consuming its liquid hydrogen and liquid oxygen propellants.

03/19/2017 03:20
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.

T+plus 7 minutes. Still looking good as Delta arcs over the Atlantic.

03/19/2017 03:24
T+plus 6 minutes, 20 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.

T+plus 12 minutes. The vehicle's steep climb leveled off as it gains speed toward orbital velocity.

03/19/2017 03:29
T+plus 11 minutes, 30 seconds. The RL10 engine is burning a mixture of liquid oxygen and liquid hydrogen cryogenic propellants.
