Lessons from the end of the ROSAT mission

26. October 2011, 16.30
The German ROSAT research satellite was launched on 1 June 1990 on a Delta II launcher and successfully scanned space for X-ray sources for nine years. Its record of achievements extends from discovering countless X-ray sources to analysing galactic clusters, X-ray binary stars and black holes to discovering the reflection of the Sun's X-ray radiation by the Moon. The findings by the scientists involved in the mission have appeared in over 7000 publications. After orbiting Earth for 21 years, ROSAT re-entered the atmosphere over the Bay of Bengal. It is not known whether any parts reached the Earth's surface.
