Headed by Principal Investigator Dr. Neil Gehrels, NASA Goddard Space Flight Center, the mission was developed in a joint partnership between Goddard and an international consortium from the United States, United Kingdom, and Italy. It is part of NASA's Medium Explorer program (MIDEX). The mission is operated at Pennsylvania State University. ==Overview== ''Swift'' is a multi-wavelength space observatory dedicated to the study of gamma-ray bursts (GRBs). Its three instruments work together to observe GRBs and their afterglows in the gamma-ray, X-ray, ultraviolet, and optical wavebands. Based on continuous scans of the area of the sky with one of the instrument's monitors, Swift uses momentum wheels to autonomously slew into the direction of possible GRBs. The name "Swift" is not a mission-related acronym, but rather a reference to the instrument's rapid slew capability, and the nimble bird of the same name. All of ''Swift''s discoveries are transmitted to the ground and those data are available to other observatories which join ''Swift'' in observing the GRBs. In the time between GRB events, ''Swift'' is available for other scientific investigations, and scientists from universities and other organizations can submit proposals for observations. The Swift Mission Operation Center (MOC), where commanding of the satellite is performed, is located in State College, Pennsylvania and operated by the Pennsylvania State University and industry subcontractors. The Swift main ground station is located at the Broglio Space Centre near Malindi on the coast of Eastern Kenya, and is operated by the Italian Space Agency. The Swift Science Data Center (SDC) and archive are located at the Goddard Space Flight Center outside Washington D.C. The UK Swift Science Data Centre is located at the University of Leicester. The ''Swift'' spacecraft bus was built by Spectrum Astro, which was later acquired by General Dynamics Advanced Information Systems,〔(【引用サイトリンク】title=Swift )〕 which was in turn acquired by Orbital Sciences Corporation. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Swift Gamma-Ray Burst Mission」の詳細全文を読む スポンサード リンク
