In this DLR webcast, Joachim Trümper, Scientific Director of ROSAT, explains the findings of the mission. From 1990 to 1999 the satellite observed more than 9000 single sources. ROSAT is the first X-ray satellite to have scanned the entire sky, and in doing so made first-time discoveries such as X-rays from comets.
At present, a total of about 6700 tons of space debris is in orbit around the Earth. This total figure includes the X-ray satellite ROSAT. In this DLR webcast, Heiner Klinkrad, Head of the Space Debris Office at the European Space Agency (ESA), explains what the re-entry of Rosat will be like, and enumerates the possible risks. He also explains the influence of solar activity on the re-entry date.
In this DLR webcast, Bernhard Schmidt-Tedd explains the legal aspects of the ROSAT mission. Space law relates to the non-territorial area of outer space, a region not governed by any national legislation, but instead governed by the United Nations Treaties and Principles on Outer Space.
In this DLR webcast, Felix Huber explains how satellites are controlled and monitored while in space, and how it is possible to extend the service life of satellites by docking a second satellite to them, and also how to 'recapture' satellites when they start to perform erratic orbital patterns.
