Ice and snow can be colourful – at least when seen through the 'eyes' of the German Aerospace Center's (DLR) TerraSAR-X radar satellite. The radar signals are able to penetrate the snow cover to a depth of one metre – and the subsurface reflects the pulse in different ways.
Viewed from above, the US 'Burning Man' festival resembles a spider web. In October and September 2011, the TerraSAR-X radar satellite, operated by DLR, acquired some impressive images of the festival and its setup process.
When a series of images acquired with the German radar satellite TerraSAR-X – operated by DLR – are combined into a sequence, the result is truly amazing; even gas storage tanks can have an eventful life of their own. The position of their covers reveals the amount of gas in the tanks; as it varies over time, TerraSAR-X gazes down at the bobbing of the gas tank covers in the Italian Porto Marghera.
The crater of the Chilean volcano Puyehue displays a striking, circular outline in this image from the German Aerospace Center (DLR) TerraSAR-X satellite – so this was not the culprit when a volcano in the southern Andes erupted on 4 June 2011. Instead, as the images from the German radar satellite show for the first time, the new eruption centre lies 6.7 kilometres further to the northwest, in the Cordón Caulle region.
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.
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.
