Mission Overview

    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, ultraviolet, and optical wavebands. The main mission objectives for Swift are to:

    • Determine the origin of gamma-ray bursts
    • Classify gamma-ray bursts and search for new types
    • Determine how the blastwave evolves and interacts with the surroundings
    • Use gamma-ray bursts to study the early universe
    • Perform the first sensitive hard X-ray survey of the sky
