Hakucho (also known as CORSA-b before launch; CORSA stands for Cosmic Radiation Satellite) was Japan's first X-ray astronomy satellite, developed by the Institute of Space and Aeronautical Science (then a division of the University of Tokyo). It was launched by the ISAS M-3C rocket on the M-3C-4 mission on February 21, 1979 and reentered the atmosphere on April 15, 1985.[1]

It was a replacement for the CORSA satellite which failed to launch due to rocket failure on February 4, 1976.[2]

  • Discovery of soft X-ray transient Cen X-4 and Aql X-1
  • Discovery of many burst sources
  • Long-term monitoring of X-ray pulsar (e.g. Vela X-1)
