NASA's Swift spacecraft blasts off from Complex 17A into the beautiful blue sky above Cape Canaveral Air Force Station on Nov. 20 at 12:16:00.611 p.m. EST aboard a Boeing Delta II expendable launch vehicle. Swift is a first-of-its-kind multi-wavelength observatory dedicated to the study of gamma-ray burst science. Its three instruments will work together to observe GRBs and afterglows in the gamma ray, X-ray, ultraviolet and optical wavebands.
