Boeing technicians in Hangar AE at Cape Canaveral Air Force Station (CCAFS) in Florida install a second ring of segments of the payload transfer canister around the plastic-wrapped Swift spacecraft. The launch of the Swift observatory, a NASA spacecraft to pinpoint the location of gamma- ray bursts, is scheduled for Nov. 17 from Pad 17-A on CCAFS. Liftoff aboard a Boeing Delta II rocket is targeted at the opening of a one-hour launch window beginning at 12:09 p.m. EST. Gamma-ray bursts are distant, yet fleeting explosions that appear to signal the births of black holes. They are the most powerful explosions known in the universe, emitting more than 100 billion times the energy that the Sun emits in a year. Yet they last only from a few milliseconds to a few minutes, never to appear in the same spot again.
