#TheDeltaFinale

What an incredible moment it was at #SpaceSymposium as a crowd gathered at the ULA booth to watch the historic final #DeltaIVHeavy launch.

Where did you watch launch from today?

#TheDeltaFinale #39Space

Let’s relive liftoff of the final #DeltaIVHeavy rocket carrying #NROL70 for the NRO, closing Delta’s six decade legacy of excellence in space!

#TheDeltaFinale

At the request of our customer, this will conclude our live coverage of today's countdown and liftoff of the #DeltaIVHeavy rocket on #NROL70 and #TheDeltaFinale from Cape Canaveral, Florida. For the final time, this is Delta Launch Control, signing off. bit.ly/div_nrol70

#DeltaIVHeavy 's metallic, tri-sector payload fairing that protected #NROL70 during ascent through the atmosphere has jettisoned at the edge of space. The rocket now weighs less than six percent of its liftoff mass. bit.ly/div_nrol70

A successful staging and start of the Delta Cryogenic Second Stage are confirmed. The center core completed its burn and separated, allowing the RL10C-2-1 engine to deploy its nozzle and ignite. bit.ly/div_nrol70

#DeltaIVHeavy is traveling 15 times the speed of sound now. Just over a minute remains in the first stage of flight. bit.ly/div_nrol70

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. bit.ly/div_nrol70

#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. bit.ly/div_nrol70

#DeltaIVHeavy is consuming 5,000 pounds of liquid hydrogen and liquid oxygen per second and now weighs only half of what it did at liftoff. The port and starboard boosters remain at full power and the center engine continues in its partial thrust mode. bit.ly/div_nrol70

The #DeltaIVHeavy rocket has broken through the sound barrier to go transonic and also passed the period of maximum aerodynamic stresses in the lower atmosphere. bit.ly/div_nrol70

One minute into the launch of #NROL70 . #DeltaIVHeavy is already traveling over 1,000 mph. The port and starboard cores are firing the RS-68A main engines at maximum power; the center booster has throttled back for fuel conservation in order to burn longer. bit.ly/div_nrol70

Three main engines up and running! And liftoff of the #NROL70 mission for the National Reconnaissance Office as the #DeltaIVHeavy rocket clears the tower for the final time!
