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.
Stefan Trommer knows what kind of person is more likely to drive an electric car, and he is also familiar with the reasons why many people are reluctant to switch to electric mobility. He found this out – together with colleagues – during Germany's largest user study on electromobility.
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.
During Mars' geological 'Middle Ages' – the Hesperian Period – which began 3.7 billion years ago and lasted until approximately 3.1 billion years ago, strong volcanic activity was present on our neighbouring planet. Volcanoes spewed low viscosity lava that poured out in masses over the surface and gave rise to extensive plains.
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.
