ASTRO-C, renamed Ginga (Japanese for 'galaxy'), was an X-ray astronomy satellite launched from the Kagoshima Space Center on 5 February 1987 using M-3SII launch vehicle. The primary instrument for observations was the Large Area Counter (LAC). Ginga was the third Japanese X-ray astronomy mission, following Hakucho and Tenma (also Hinotori satellite - which preceded Ginga - had X-ray sensors, but it can be seen as a heliophysics rather than X-ray astronomy mission). Ginga reentered the Earth's atmosphere on 1 November 1991.
