Tenma (Japanese for "Pegasus").

Tenma, known as ASTRO-B before launch (COSPAR 1983-011A, SATCAT 13829), was a Japanese X-ray astronomy satellite, developed by the Institute of Space and Astronautical Science. It was launched on February 20, 1983 using a M-3S rocket on the M-3S-3 mission.

Battery failure in July 1984 caused the operation to become limited, and continuing problems lead to the termination of X-ray observation in 1985. It reentered the atmosphere on January 19, 1989 (other sources, for example the NORAD catalog of satellites, say decay date was 17 December 1988[1]).
