The second ISAS X-ray astronomy satellite, CORSA-b, was launched in Feb 1979. The satellite was renamed Hakucho (`Cygnus'). It was 97 kg in mass, and 0.66m long, 0.82m diameter.
The craft was spin stabilized with a 12s period. By 1983 it was dormant, and it was finally abandoned in 1985.
The M-3C-4 rocket used the M-3A2 model third stage.
