In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface.
Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h. Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR in Wachtberg near Bonn have already been monitoring Tiangong-1 for a number of weeks with their TIRA (Tracking and Imaging Radar) system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center (WRLageZ) and the ESA (European Space Agency) with their re-entry forecasts.
