ASTRO-C, renamed Ginga (Japanese for 'galaxy'), was launched from the Kagoshima Space Center on 5 February, 1987. The primary instrument for observations was the Large Area Counter (LAC). Ginga was the third Japanese X-ray astronomy mission, following Hakucho and Tenma. Ginga reentered the Earth's atmosphere on 1 November, 1991.
