ROSAT Re-entry ROSAT (short for Rö ntgen sat ellit, in German X-rays are called Röntgenstrahlen, in honour of Wilhelm Röntgen ) is a defunct German Aerospace Center -led satellite X-ray telescope , with instruments built by Germany, the UK and the US. It was launched on 1 June 1990, on a Delta II rocket from Cape Canaveral , on what was initially designed as an 18 month mission, with provision for up to 5 years of operation. ROSAT actually operated for over 8 years, finally shutting down on 12 February 1999. ROSAT is expected to re-enter the Earth's atmosphere between October 21 and 23 2011. In February 2011, it was reported that the 2,400 kg satellite was unlikely to burn up entirely while re-entering the earth atmosphere due to the large amount of ceramics and glass used in construction.
