The Dawn launch has been postponed until Sunday and possibly later due to weather. See news below.

The Dawn spacecraft, mounted with its third-stage booster atop the Delta II launcher on Cape Canaveral AFS Pad 17-B, is seen with one-half of its aerodynamic fairing being attached to the rocket. Added highlighting outlines the dark spacecraft and its folded solar arrays against the dark inside of the fairing. The smaller image shows the whole fairing almost fully installed.
