In Hangar AE at Cape Canaveral Air Force Station, the Swift spacecraft waits for final removal of the protective cover (at top). Swift is a first-of-its-kind, multi-wavelength observatory dedicated to the study of gamma-ray burst (GRB) science. Its three instruments will work together to observe GRBs and afterglows in the gamma-ray, X-ray and optical wavebands. Swift is part of NASA’s medium explorer (MIDEX) program being developed by an international collaboration. During its nominal 2-year mission, Swift is expected to observe more than 200 bursts, which will represent the most comprehensive study of GRB afterglow to date. It is scheduled for launch into a low-Earth orbit on a Delta 7320 rocket on Oct. 7.
