With its research and management divisions, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) contributes to the solution of global challenges. The work includes not only the reduction of emissions caused by air transport, but also highly automated travel for the mobility of the future, cost-effective energy storage solutions and environmental monitoring for the protection of the atmosphere.
A comet is largely composed of water ice and water vapour predominates in its 'atmosphere' – the coma that forms as it nears the Sun. However, very few examples of water ice have previously been observed on the surface of a comet.
Currently just 385 kilometres away from the surface, the Dawn spacecraft is orbiting Ceres and acquiring images that show the dwarf planet at an unprecedented resolution of just 35 metres per pixel. These images allow scientists to look at a surface strewn with craters, fractures, domes and bright areas.
The last clear sign of life was received from Philae, the Rosetta mission's comet lander, on 9 July 2015; since then, it has remained silent. Now, Comet 67P/Churyumov-Gerasimenko is moving away from the Sun and the temperature on the comet's surface and the amount of sunlight are both decreasing.
Although it is a simple gesture of greeting, it nevertheless remains an extraordinary moment; a handshake between an astronaut on the International Space Station (ISS) and researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR).
Arable land disappeared from city centres, where most people live, many years ago. Nowadays, food is transported over long distances before reaching the consumer. Researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have now joined with international partners to create 'Vertical Farm 2.0', which will enable the multi-level cultivation of plants in large cities.
On Tuesday 8 December at the 2015 UN Climate Change Conference COP 21 in Paris, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and the French space agency (CNES) met to reaffirm their commitment to jointly develop the MEthane Remote sensing LIdar missioN (MERLIN) satellite that is set to measure concentrations of methane in Earth's atmosphere with unprecedented accuracy.
The science and technology demonstrator LISA Pathfinder lifted off from Europe's Spaceport in Kourou, French Guiana on board a Vega rocket at 05:04 CET on 3 December 2015. Preparations for this European Space Agency (ESA) mission, which places unprecedented requirements on both payload and spacecraft, have lasted more than 10 years.
Mobile telephones, high-speed Internet, up-to-date meteorological data and navigation programs available anytime, anywhere – all thanks to satellites. Bandwidth and frequencies that are revised every three to four years at the World Radiocommunication Conference play an important role in this.
The dwarf planet Ceres measured a mere nine pixels across on an image acquired by NASA's Dawn orbiter on 1 December 2014. Since then, the planetary researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have received thousands of images showing the dwarf planet and its unusually varied surface.
Philae was more than 500 million kilometres from Earth when it touched down on Comet 67P/Churyumov-Gerasimenko one year ago, on 12 November 2014. "We looked after and planned this mission for almost 20 years and launched the Rosetta orbiter and Philae lander on their journey through space – so landing day really was quite special," says Philae Project Manager Stephan Ulamec from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) to sum up the mood on the day.
Indonesia is on fire – the island state is currently facing a bitter struggle against forest and peat fires on Sumatra and Borneo, most likely caused by illegal 'slash and burn' farming to clear the land for palm oil or timber plantations. The extremely dry conditions resulting from the El Niño weather phenomenon exacerbate this problem.
When astronaut William Shepherd left Earth on 31 October 2000 aboard Space Shuttle Discovery, he made his way to a very special residence. At an altitude of approximately 400 kilometres, it offered an unobstructed view of Earth and no risk of meeting unfriendly neighbours.
The students cheered – the DECAN (Deutsche CanSat Höhenrakete) research rocket took off from the Esrange Space Center in north Sweden at 02:53 on 27 October 2015 and proceeded to reach an altitude of roughly 5.5 kilometres. The rocket was designed, built and launched by a team of students from Technische Universität Berlin (TU Berlin) as part of the new STERN (Studentische Experimental-Raketen) German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) programme.
The ozone hole over Antarctica currently extends over 26 million square kilometres – an area larger than the North American continent. Currently, it is approximately 2.5 million square kilometres larger than at the same time in 2014. In 2006 it was larger than now, at 27 million square kilometres.
"In your face, Neil Armstrong!" – as he says these words, NASA astronaut Mark Watney senses for the first time that he might have only a very small chance of getting out of his predicament alive. Watney is 'The Martian' in the film of the same name (release date in Germany: 8 October) who, in a not too distant future, finds himself stranded on the Red Planet.
This week, scientists at the European Planetary Science Conference (EPSC) in Nantes, France are busy with the mysterious crater structures and fascinating views of the multifaceted dwarf planet Ceres. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is involved in the NASA Dawn mission and, among other things, is responsible for the mapping and naming of regions and striking surface features, in collaboration with the International Astronomical Union (IAU).
Shaped like a rubber duck – this was the talk upon the discovery of Comet 67P/Churyumov-Gerasimenko's surprising shape in July 2014. Scientists were amazed at the celestial body's extraordinary shape, which was revealed by the European Rosetta spacecraft.
Gas and dust streams from the ‘neck’ of Comet 67P/ Churyumov-Gerasimenko
Since its arrival at the comet, Rosetta has observed jets of gas and dust. Numerous gas eruptions have been observed originating from the ‘neck’ of the comet. Using the measurements performed by the VIRTIS spectrometer, it has been possible to recognise a day/night cycle of cometary activity and identify the mechanism responsible.
The north face of the Eiger in the Bernese Alps is legendary; mountaineers consider the steep walls of the 1800-metre drop to be a difficult and challenging climb. But 326 million kilometres from Earth, the sheer cliffs of the Eiger find their match on the dwarf planet Ceres, where at some points, the wall of the Occator crater towers precipitously at a height of almost 2000 metres.
