Comments: The Swift Gamma Ray Burst Explorer is a three-telescope space observatory for studying gamma ray bursts (GRBs) and monitoring the afterglow in X-ray, and UV/Visible light at the location of a burst. Burst detection rate is expected to be greater than 100 per year, with a sensitivity ~3 times fainter than the BATSE detector aboard the Compton Gamma-Ray Observatory. The Swift mission has a nominal on-orbit lifetime of 2 years.
