Entering a planetary atmosphere is one of the most critical mission phases for a spacecraft. The enormous amount of heat generated not only places heavy thermal loads on the material of the re-entry vehicle, it also gives rise to an electrically charged plasma that flows around it. This blocks radio signals, with the result that the spacecraft is unable to communicate with its ground stations for several minutes. In a joint project, researchers at the German Aerospace Center (DLR) are working with colleagues at Stanford University in California to find a solution to this problem.
The dwarf planet Ceres would be quite an uncomfortable place if one were to actually stand on its surface – with a rather 'chilly' temperature of minus 60 degrees Celsius by day, which gets colder during the night. Hard, frozen ground and craters spanning kilometres – in all shapes and sizes.
Gravity waves affect the climate and weather. For the first time ever, scientists from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), together with colleagues from the Karlsruhe Institute of Technology (Karlsruher Institut für Technologie; KIT) and the Jülich Research Centre (Forschungszentrum Jülich), as well as other national and international partners, have succeeded in measuring almost the entire life cycle of atmospheric gravity waves.
The German Aerospace Center (DLR) is supporting the Indian power provider NTPC in its project to establish a research centre to test and develop solar power plants and their components. DLR researchers are supplying systems, measurement equipment and expertise, and are helping to select suitable power plant locations. The recently launched project will run for three years and is supported by the Kreditanstalt Development Bank (KfW) with funds provided by the German Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety.
On 23 January 2016, five German science experiments travelled on board a German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), TEXUS sounding rocket, to take a 'short trip' in microgravity.
Aviation in Europe needs to become more environmentally friendly and quieter. To get to the 'core' of aircraft noise on the ground, researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) dismantled current aircraft engines and began conducting physical modelling.
On 19 January 2016, Klaus Uckel, Director of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Project Management Agency, and Wang Ruijun, Director General of the National Center for Science and Technology Evaluation (NCSTE), signed an agreement for closer collaboration in programmes to promote research and innovation support systems.
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.
An unmanned, electric, autonomous aircraft travelling at 75 kilometres per hour lands gently on the roof of a moving car. For the first time, researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have successfully demonstrated a technique developed for this purpose.
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.
