Despite numerous holds and resets, the Delta IV Heavy finally rose
ponderously through its own flames and ever so slowly cleared the
tower into the night skies of Florida. At the end of the broadcast,
the upper stage was running and payload fairing separation had been]
confirmed.

As this is apparently GEO mission with three RL10 burns scheduled,
the launch is still proceeding and word of spacecraft separation
won't come for several hours.
