When aircraft are in flight, vortices are generated behind them from the wing tips. These are known as wake vortices, and they can have safety implications for following air traffic. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has now tested the improvement of a wake vortex avoidance system in flight tests.
Brussels – The European satellite navigation system Galileo took another step toward future routine operations on 15 December 2016. Acting on behalf of the European Commission, the European GNSS Agency (GSA) has assigned the responsibility for operating Galileo in the next 10 years to the firm Spaceopal from Munich. The contract was signed on this day in Brussels.
The Occator crater on the dwarf planet Ceres is a real eye-catcher: with a diameter of 92 kilometres, it is larger than Tycho crater on the Moon – which appears like a bright spot when seen with the naked eye. The Occator crater's steep walls stand tall at over 2000 metres, higher than the North face of the Eiger in the Bernese Alps.
The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) will send the 'Mole' HP3 (Heat Flow and Physical Properties Package) to Mars on board the United States InSight Mission on 5 May 2018 to conduct heat flow measurements. And it has just received good news: the landing site in the plains of Elysium Planitia most probably has a heat flow that is classified average, and will therefore be representative of Mars as a whole.
Approximately 600 kilometres long and up to two kilometres deep, Mawrth Vallis is a dried-up outflow channel on our planetary neighbour Mars. The High Resolution Stereo Camera (HRSC) operated by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) on board ESA's Mars Express spacecraft has imaged the valley in high resolution.
For the first time in the history of space exploration, scientists at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have demonstrated in a real space experiment how a satellite can approach a counterpart by fully autonomously, making use of only optical or vision-based navigation.
The highest decision-making body of the European Space Agency (ESA) met this year on 1 and 2 December at the Culture and Convention Centre (KKL) in Lucerne, Switzerland, to set the financial and programme-based course for European space travel for the coming years. Ministers in charge of space in Europe last came together exactly two years ago on 2 December 2014 in Luxembourg.
International policy-makers have set ambitious goals to reduce greenhouse gas emissions as part of the Paris Agreement regarding climate change. Monitoring emissions will play a crucial role here. Greenhouse gas sources and sinks need to be investigated as accurately as possible in order to obtain reliable climate forecasts. In spring 2017, the research aircraft HALO (High Altitude and LOng Range Research Aircraft) is set to target carbon dioxide and methane, the two most significant greenhouse gases, with its innovative instruments, acquiring data stretching from Europe to North Africa, which is currently lacking.
On behalf of Greenpeace International, researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have analysed what the energy supply in Brazil could be like by 2050 if the accelerated expansion of renewable energies and efficiency measures can be structured in a sustainable manner.
The plasma crystal experiments are among the most successful research projects on the International Space Station (ISS). The PKE-Nefedov plasma crystal laboratory was one of the first scientific research laboratories on the International Space Station (ISS).
David the robot is characterised by his clear-cut design. Its purpose is to emphasise his capabilities and avoid any confusion about his limitations, explains his designer, Tilo Wüsthoff. The last issue of the DLRmagazine in 2016 profiles the designer, who has a somewhat atypical job at DLR.
The Rosetta mission reached the end of its observation phase in late September when the orbiter touched down spectacularly on the surface of Comet 67P/Churyumov-Gersimenko. By then, it had spent 4595 days in space, and had travelled 7.9 billion kilometres, performed a total of six fly-bys past Earth, Mars and two asteroids and accompanied Comet 67P during its journey through the Solar System on a mission lasting more than two years.
Antonianna, Lisa, Kimberley and Tijmen – those are the names of the four Galileo satellites launched on 17 November 2016, at precisely 14:06 CET, for the first time with a specially adapted version of the European heavyweight carrier Ariane 5 from the European spaceport in French Guiana.
The Budget Committee of the German Federal Government has approved 42 million euro in funding to establish six new institutes within the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR).
Human beings do not always retain the same level of dexterity in a weightless environment as they would on Earth – not even with practice. This is a familiar, yet still mysterious, phenomenon encountered in human spaceflight: what is the reason for the reduced hand-to-eye coordination in space, and what can be done to compensate these performance deficits?
At 10:30 Central European Time (CET) on 8 November 2016, the HEROS3 (Hybrid Experimental Rocket Stuttgart) research rocket was successfully launched from the Esrange Space Centre in Sweden to great enthusiasm from the students. Reaching an altitude of 30 kilometres, it set a new European altitude record for student rockets.
The menu for polar explorers in the Antarctic is not usually very exciting. Often, there are only durable goods, especially in the polar winter, when the researchers are cut off from the outside world for months.
A unique experiment – with a very special goal – has been devised by the German Space Operations Center (GSOC) of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR). The AVANTI experiment (Autonomous Visual Approach Navigation and Target Identification) is intended to demonstrate how a satellite can detect a spacecraft in space and approach it autonomously.
These images, acquired by the High Resolution Stereo Camera (HRSC) operated by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) on board the European Mars Express spacecraft show the western part of Acheron Fossae, a network of fractures on Mars.
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.
