Home. Heavens-Above. ROSAT Re-entry. ROSAT (short for Röntgensatellit, 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.

UKIDSS Galactic Plane Survey (GPS) Mosaic - DR7 The main window below displays a 6 billion pixel (1 arcsec pixels) mosaic of the GPS (centre: l=52, b=0 (109 > l > 0 ,360 > l > 355 and -2.5 < b < +2.5). Use the controls in the main window or the mouse (click&drag ) to move around the image and zoom in and out. Click on the small images on the left to move to that point in the mosaic.
