| | Corsa-B was the first X-ray astronomy Japanese satellite. Launched on 21 February 1979, it was renamed Hakucho (Japanese for swan) symbolizing one of the most interesting X-ray objects, Cyg X-1. As many other X-ray satellite launched in that period, Hakucho was designed to study and monitor transient phenomena with particular emphasis on X-ray bursts. It was still operating when the second X-ray Japanese satellite Tenma launched in 1983. Mission Characteristics Lifetime : 21 February 1979 - 16 Aprile 1985 Energy Range : 0.1 - 100 keV Payload : Very Soft X-ray (VSX) experiment 0.1-0.2 keV Four units of proportional counters each with eff area ~ 78 cm2 Two parallel to the spin axis FOV = 6.3° X 2.9° FWHM two offset FOV = 24.9° X 2.9° FWHM Soft X-ray (SFX) 1.5-30 keV Six units of proportinal counters Parallel to the spin axis : Two FOV 17.6 deg FWHM; eff area=69 cm2 each Two FOV 5.8 deg FWHM; eff area=40&83 cm2 Two offset FOV = 50.3° X 1.7° FWHM eff area =32 cm2 each Hard X-ray (HDX) 10-100 keV scintillator FOV 4.4° X 10.0° FWHM eff area =45 cm2 Science Highlights: Discovery of soft X-ray transient Cen X-4 and Apl X-1 Discovery of many burst sources Long-term monitoring of X-ray pulsar (e.g. Vela X-1) Discovery of 2 Hz variability in the Rapid Burster later named Quasi Period Oscillation.
