Researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have set a new record in data transmission using laser: 1.72 terabits per second across a distance of 10.45 kilometres, which is equivalent to the transmission of 45 DVDs per second.
Showcasing and promoting outstanding and innovative concepts for applications of satellite navigation and Earth observation are the objectives of the 'European Satellite Navigation Competition' (ESNC) and 'Copernicus Masters', two ideas competitions.
The German satellite duo TerraSAR-X and TanDEM-X have consistently delivered one-of-a-kind Earth observation data since 2007 and 2010, hence shaping the international research landscape. Now, scientific users from across the globe have gathered for the TerraSAR-X and TanDEM-X Science Meeting at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) in Oberpfaffenhofen, where they will discuss the results obtained from the data and define requirements for future remote sensing technology.
More than 1.5 million children and their families in over 130 countries around the world are currently receiving support from the humanitarian aid organisation SOS Children's Villages International. The Centre for Satellite Based Crisis Information (ZKI) at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) site in Oberpfaffenhofen is supporting the organisation by establishing emergency and disaster management concepts in order to provide effective assistance in the event of natural disasters, such as floods, earthquakes or forest fires.
The new three-dimensional map of Earth has been completed. Mountain peaks and valley floors across the globe can now be seen with an accuracy of just one metre. The global elevation model was created as part of the TanDEM-X satellite mission; it offers unprecedented accuracy compared with other global datasets and is based on a uniform database.
Vegetation and soil are currently slowing down global warming by absorbing about a quarter of human emissions of carbon dioxide (CO2). This land carbon sink is believed to be in part due to increases in photosynthesis. A new study in the journal Nature shows that doubling of the carbon dioxide concentration in the atmosphere will cause global plant photosynthesis to increase by approximately one third.
Everyone knows this situation with a weather forecast, when the presenter reveals a new Icelandic low on the map. Very soon, they are then often told, the trough of low pressure will reach the mainland and determine the weather for many days in Europe. Small errors often lead to the forecast in Europe being very uncertain for several days, because the system develops vigorously in the 'weather kitchen' over the Atlantic, and that is difficult to capture in weather models.
What do the Moon and Mount Etna have in common? An extreme surface as well as extreme conditions. Twenty-one scientists from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) are using the harsh conditions on the volcano to test technologies for future Solar System exploration missions.
With a diameter of 20 metres, Earth appears to float above visitors to the Gasometer Oberhausen, while banks of clouds, days and nights – and even rain showers – flow across its surface. Over half a million people have already visited the 'Wonders of Nature' exhibition, making this display in the old industrial monument one of this year's most popular exhibitions.
With a new Malik Verlag publication, 'm4 Mountains – Die vierte Dimension' (m4 mountains – the fourth dimension), the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) presents another image book from the world of satellite-supported Earth observation. In 200 pages, Stefan Dech and Nils Sparwasser, together with mountaineering legend Reinhold Messner, show some of our planet's fascinating mountains in a completely innovative way.
