Lua error in package.lua at line 80: module 'strict' not found.

Hakucho (also known as CORSA-b before launch) 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-4 rocket on February 21, 1979 and reentered the atmosphere on April 16, 1985[citation needed].

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