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.
On 9 September 2016 at 13:00 CEST, the BIROS (Bi-Spectral Infrared Optical System) fire detection satellite developed and built by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) released BEESAT-4 (Berlin Educational and Experimental Picosatellite) into space 515 kilometres above the Norwegian Svalbard archipelago.
Four days and four cases that pose a threat to maritime security – in several scenarios that took place between 5 and 9 September 2016, the EMSec joint project (Echtzeitdienste für die Maritime Sicherheit - Security; Real-Time Services for Maritime Security) was able to successfully demonstrate research findings from the last three years.
What effects do tropical clouds have on our climate? Do they warm up or cool down the atmosphere? What factors do they influence? Even the latest models do not fully understand the effects of these climate-influencing 'clouds'.
In the Situation Centre, an alarm flashes on the screen – a passenger ferry has changed its planned course for no apparent reason. The AIS (Automatic Identification System) signal eventually disappears from the display. By now, all ship-specific information must have been requested and compared in order to quickly clarify the situation and take immediate action.
West Africa is changing. An explosively growing population, massive urbanisation, complex meteorological influences, unregulated deforestation and air pollution modify the composition of the atmosphere, not only impacting human health but also the weather and climate. How bad the problem actually is and how exactly these emissions are changing the region in the long-term is not yet clear. Researchers from the German Aerospace Center (DLR) used the Falcon research aircraft to analyse the tropical air on the West African coast in order to determine its composition and its effect on the clouds’ climate-relevant properties. The measurement flights were part of the five-year EU project DACCIWA (Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa)..
Ships can be led astray with fake GPS signals. If signals for navigation of vessels are jammed or spoofed, positional and other critical data, such as course and speed, can be affected. Researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have tested new receiver systems and methods for suppressing interference in a three-day measurement campaign.
The exterior of a rocket is exposed to extremely high temperatures during hypersonic flight. But how exactly does the surface structure change under varying air resistance and with respect to heat flow and acceleration?
