Technicians secure both halves of the fairing around the Dawn spacecraft to the upper stage booster of the Delta II rocket below.

Inside the mobile service tower on Launch Pad 17-B at Cape Canaveral Air Force Station, technicians secure both halves of the fairing around the Dawn spacecraft to the upper stage booster of the Delta II rocket below. The fairing is a molded structure that fits flush with the outside surface of the Delta II upper stage booster and forms an aerodynamically smooth nose cone, protecting the spacecraft during launch and ascent. Dawn is scheduled to launch between 7:25 and 7:54 a.m. on Sept. 26 aboard a Delta II rocket. Photo credit: NASA/Jim Grossmann
