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_nrol68
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_nrol68
#DeltaIVHeavy's metallic, tri-sector payload fairing that protected #NROL68 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_nrol68
