The Ginga Satellite
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.
