In which quantity are trace gases, such as nitrogen dioxide, ozone, formaldehyde, sulphur dioxide, methane and carbon monoxide, present in our atmosphere? How high are the global and regional concentrations of aerosol particles? Which processes induce changes in our environment, and how do they affect our climate, air quality, and therefore our health?
The venture to cultivate plants in the Antarctic is gathering momentum: on 8 October 2017 the special EDEN ISS greenhouse container, packed safely away on a cargo ship, left the Port of Hamburg en route to the Ekström ice shelf in the Antarctic.
The voyage to Mars, our red planetary neighbour, is more than just a dream – it is a definite goal for human spaceflight. But a whole series of scientific questions need to be answered before this kind of journey can be undertaken.
Electromobility is already deeply ingrained in the European automotive industry and transport research. Moreover, the development of electrical drive systems for automotive applications has also given momentum to the vision of electric and carbon-neutral aviation.
Two impact craters with expanses of dunes, located deep in the southern highlands of the Red Planet, can be seen in these images acquired by the High Resolution Stereo Camera (HRSC) on board the ESA Mars Express spacecraft. The HRSC was developed and is operated by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR).
Representatives of international space agencies, the industrial sector and research institutes gathered at the International Astronautical Congress (IAC) from 25 to 29 September 2017 in Adelaide, Australia. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) took this opportunity to sign a number of Memorandums of Understanding for closer collaboration with international partners.
The German Aerospace Center (Deutsches Zentrum für Luft-und Raumfahrt; DLR) and the renowned University of Sydney have declared their intention for future cooperation in research and teaching activities related to aerospace research by signing a Memorandum of Understanding (MoU) on 27 September 2017 at the International Astronautical Congress in Adelaide, Australia.
Aerospace students are constantly coming up with new ideas, hoping to achieve a breakthrough design for the aircraft of the future. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and US space agency NASA organised a joint student competition that put two specific challenges forward,
Ten years ago, NASA's Dawn space probe embarked on a mission destined to become one of the most exciting and scientifically productive in the history of unmanned exploration of the Solar System. On board is the German framing camera that is providing fundamental information on planetary formation from Vesta and Ceres.
The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), the Japanese space agency, JAXA, and the National Institute of Advanced Industrial Science and Technology in Japan (AIST) signed two cooperation agreements on 21 September 2017 in Tokyo.
Electric propulsion systems are considered to be particularly promising space technology. Although they produce less thrust, their fuel efficiency is significantly higher than that of conventional chemical engines. Satellites can thus be made considerably lighter and more durable. Additionally, the payload capacity can be increased because of the lower fuel mass needed.
The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) will be showcasing its latest research at this year's International Astronautical Congress (IAC) in Adelaide, Australia.
Despite their large potential to reduce emissions and increase transport efficiency, cargo bikes have thus far not been used to any significant extent for business purposes. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is seeking to exploit this potential to the greatest possible extent in the new nationwide 'I unload cities' project.
One hundred tons of molten salt circulate through the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) test facility in Cologne. The molten salt is alternately heated and cooled from 250 to 560 degrees Celsius.
Over billions of years, meteorite impacts have altered the surface of Mars. Current images from the High Resolution Stereo Camera (HRSC) operated by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) on board the ESA Mars Express spacecraft show an impact crater over 30 kilometres in size with a prominent ejecta blanket. It is located to the north of the largest impact basin on Mars, Hellas Planitia, where some scientists believe there was once a large lake.
Since the first observation of an extrasolar planet, or exoplanet, almost 4000 planets have been identified orbiting other stars in the Milky Way. With these new discoveries, scientists are now increasingly investigating their atmospheres, the composition and structure of gas hull.
There are a total of 18 scientific instruments on board Cassini-Huygens. One of these is the Cosmic Dust Analyzer (CDA), which analyses ice and dust particles in the Saturnian system. The special thing about this instrument, which is still the only one in the world, is that it can simultaneously determine the electrical charge, speed, direction of flight and mass of individual particles.
Without solar and wind power there would be no Energiewende (energy transition). And no energy transition without energy storage. Energy storage materials store the energy and release it when it is needed. Salt could play an important role here.
Twenty nine parabolic flight campaigns run by the Space Administration of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have resulted in 97 flight days, 3270 parabolas and almost 19 hours of microgravity.
Today, thanks to Cassini, we know 62 of Saturn's moons. Maps are important to be able to study them further. The DLR Institute of Planetary Research has produced maps for the seven medium-sized ice moons Mimas, Enceladus, Tethys, Dione, Rhea, Iapetus and Phoebe, based on high-resolution images acquired by the camera on board Cassini.
