As in the case of many other X-ray satellites deployed around this time, Hakucho was designed to study and monitor transient (quick-changing) phenomena, with special emphasis on X-ray bursts in the energy range 0.1-100 keV. It was known prior to launch as Corsa-B. Hakucho stopped operating in April 1985. Launch date Feb. 21, 1979 Launch vehicle M-3S Launch site Kagoshima Orbit 543 × 566 km × 29.8° Mass 96 kg Related entry    • X-ray satellites Related categories    • JAPANESE SPACECRAFT    • SATELLITES AND SPACE PROBES    • JAPAN IN SPACE Also on this site: Encyclopedia of Alternative Energy & Sustainable Living Encyclopedia of History Transport Concepts & Designs (partner site) BACK TO TOP
