Höhenmodelle der SRTM%2dMission kostenfrei zur Verfügung

Elevation models from SRTM now available for download free of charge

25. May 2011

When Space Shuttle Endeavour launched on 11 February 2000 for the 'Shuttle Radar Topography Mission' (SRTM), it was carrying two radar antennas; one in the shuttle's payload bay and the other on the end of a 60-metre mast. Over the course of eleven days, researchers at the German Aerospace Center (DLR) acquired data for a three-dimensional terrain model of large areas of the Earth. Now, DLR is making these data available for scientific purposes free of charge.

TerraSAR%2dX%2dBild des Monats: Istanbul %2d "Flächenfraß" einer Metropole

TerraSAR-X image of the month - Urban sprawl around Istanbul

17. May 2011

Nobody knows exactly how many people live in Istanbul, but there are thought to be about 15 million inhabitants of this city on two continents. Images from the German Aerospace Center (DLR) TerraSAR-X radar satellite are giving urban planners a more accurate view of something slightly different – how much the city on the Bosphorus has spread out recentlyreitet.

TerraSAR%2dX%2dSatellitendaten zeigen Zerstörungen des Tsunamis in Japan

TerraSAR-X satellite data reveals destruction caused by tsunami in Japan

16. March 2011

For the latest maps from the DLR Center for Satellite Based Crisis Information, click here. The German Remote Sensing Data Center (Deutsches Fernerkundungsdatenzentrum; DFD) and the German Space Operations Center (GSOC), both of which are part of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), are continuing to provide as much data as possible from the two German radar satellites, TerraSAR-X and TanDEM-X, for the assessment of damage caused by the recent tsunami in Japan. Radar data, in contrast to data from optical satellites, can be acquired independently of cloud cover or time of day and allow precise identification of the flooded and destroyed areas on the east coast of Japan.

DLR veröffentlicht Satellitenbilder des japanischen Katastrophengebiets

DLR releases satellite images of Japanese disaster area

12. March 2011

After the severe earthquake and tsunami in Japan, the International Charter 'Space and Major Disasters' was activated on the morning of the 11 March 2011. All participating institutions were asked to provide satellite imagery of the affected area. The German Aerospace Center (DLR) is responding through its Center for Satellite Based Crisis Information (ZKI) in Oberpfaffenhofen.

Entwicklung der Ozonschicht: DLR%2dWissenschaftler tragen zu neuen Erkenntnissen bei

DLR researchers contribute new insights on changes in the Ozone Layer

23. February 2011

German Aerospace Center (DLR) researchers have been instrumental in the preparation of a report on the changes in the Ozone Layer for the World Meteorological Organization (WMO). The report was published online by the Geneva-based WMO in January. Recent estimates suggest that, by the middle of the 21st century, the thickness of Ozone Layer will be the same as in the early 1980s.

TerraSAR-X-image of the month: Calving icebergs on Queen Maud Land

8. February 2011

If the city of Bonn were located on the edge of the Fimbul Ice Shelf, in the Antarctic, its inhabitants would now be embarking on a journey through the Antarctic Circumpolar Current. An iceberg the size of Bonn – with a surface area of 120 square kilometres – has calved in the Atlantic. Glaciologists at Hamburg University's Climate Campus have been using the German Aerospace Center (DLR) radar satellite, TerraSAR-X, to observe the area from an altitude of 500 kilometres and gain a better understanding of how icebergs like this will calve in the future.
