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.
Larger and more powerful engines are making flying more efficient. These gigantic main engines take up more space on the wings of modern passenger aircraft. However, they influence the flow over the wing surface and reduce lift.
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.
NORAH (NOise-Related Annoyance, cognition, and Health) is the largest European-level study on the effects of air, road and rail traffic noise. The results have recently been released by the Environment and Community Centre (Umwelt- und Nachbarschaftshaus), a subsidiary of the German state of Hesse and part of the Forum Airport and Region (Forum Flughafen und Region).
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.
Europe is home to some 450 airlines, 700 airports and a world-leading aviation industry. For 15 years, the Advisory Council for Aviation Research and innovation in Europe (ACARE) has been bringing together the foremost commercial and scientific representatives in the European aviation industry to jointly develop guidelines for European aviation research.
With the project for the HY4 four-seater aircraft, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is taking another major step towards making zero-emission flying a reality – the HY4 will be the world's first four-passenger aircraft powered solely by a hydrogen fuel cell battery system.
Alternative fuels have the potential to support the environment- and climate-friendly developments in air transport. At present, global air traffic contributes towards almost five percent of global warming. In addition to the greenhouse gas carbon dioxide, condensation trails and the resulting cirrus clouds lead to a significant climate impact.
"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.
Over 60,000 guests visited the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Cologne-Porz site on 20 September 2015 for German Aerospace Day. DLR and the European Space Agency (ESA), together with their partners, exhibited current research projects and missions in the fields of aeronautics, space, energy, transport and security.
The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is opening its doors to their laboratories and institutes on German Aerospace Day, offering visitors an insight into the ongoing research. Teaming up with the event partners – the European Space Agency (ESA), Cologne Bonn Airport and the German Air Force – DLR will showcase a major aircraft exhibition alongside the astronaut training facilities in the EAC (European Astronaut Center).
From 9 September 2015, test flights are taking place on three consecutive days in a simulated disaster scenario as part of the EU's 'Driving Innovations in Crisis Management for European Resilience' (DRIVER) project. Harrowing scenes are being simulated in Braunschweig on those days. A major flood has covered a wide area around the Tankumsee, a lake near Gifhorn; surrounding roads are also affected and people are stranded in the water.
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.
