ROSAT

Satellite X-ray telescope

ROSAT (short for Röntgensatellit; in German X-rays are called Röntgenstrahlen, in honour of Wilhelm Röntgen) was a German Aerospace Center-led satellite X-ray telescope, with instruments built by West Germany, the United Kingdom and the United States. It was launched on 1 June 1990, on a Delta II rocket from Cape Canaveral, Florida, on what was initially designed as an 18-month mission, with provision for up to five years of operation. ROSAT operated for over eight years, shutting down on 12 February 1999.
