ROSAT weighs about 5,348 pounds (2,426 kilograms) and launched into orbit in June 1990 as part of a joint mission by Germany, the United States and the United Kingdom. In 1998, the satellite's star tracker failed, which caused its X-ray sensors to point directly at the sun. This permanently damaged the spacecraft, and ROSAT was officially decommissioned in February 1999. Sorry Joerg! ;-)
