TENMA, which means "pegasus" in Japanese, is the second Japanese
X-ray astronomy satellite. TENMA, formerly known as ASTRO-B, was
launched by the M-3S-3 rocket on February 20, 1983, at Kagoshima Space
Center (KSC). It had observed the X-ray sources from space, including X-ray
stars, X-ray galaxies, gamma-ray bursts, and soft X-ray nebulae until it
rentered the earth's atmosphere on January 19, 1989.
