Market-ready: Electric propulsion systems 'made in Germany'

22. September 2017

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.

Greenhouses for the Moon, moles for Mars

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.

Quieter and greener transport through the city centres on e-cargo bikes

18. September 2017

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.

Auskristallisiertes Salz

The power of salt

15. September 2017

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.

Muddy impact on Mars

14. September 2017

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.

Titanium oxide in the atmosphere of a 'hot Jupiter' exoplanet

13. September 2017

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.

The Cosmic Dust Analyzer – a joint project by Max Planck and DLR

13. September 2017

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.

DLRmagazine 154/155 - The Power of salt

12. September 2017

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.

#DLRparabolicflights – major milestone for experiencing microgravity in real time

11. September 2017

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.

Turning image data into an atlas – Mapping the moons of Saturn

7. September 2017

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.

From 1997 to 2017 – an intriguingly complex mission comes to an end

1. September 2017

On 15 October 1997 the Cassini spacecraft took off from Cape Canaveral and embarked on an almost seven-year journey to the Saturn System, atop a Titan 4B rocket. It circled the planet and its numerous glacial moons for almost 13 years, from 2004 to 2017.

DLR provides satellite data for Hurricane Harvey

30. August 2017

In anticipation of the catastrophic Hurricane Harvey, the International Charter 'Space and Major Disasters' was activated early on the evening of 24 August 2017. This was initiated by the Charter member United States Geological Survey (USGS) on behalf of the Texas Emergency Management Council. The German Aerospace Center (DLR) provided real-time recordings and archive data from the German radar satellite TerraSAR-X, which enabled a detailed analysis and an overview of the flood situation. Using these and other satellite data provided by 16 Charter members, the Center for Space Research at the University of Texas is currently working on providing assistance and information to disaster relief personnel on the ground.

“Over to you, Justin!”

25. August 2017

On 25 August 2017, the Italian ESA astronaut Paolo Nespoli, currently residing on the International Space Station (ISS), remote-controlled the German Aerospace Center (DLR) Rollin’ Justin robot. During the experiment, a tablet-PC was used to send instructions to the robot at the DLR Institute of Robotics and Mechatronics in Oberpfaffenhofen from the ISS. Justin was then left to his own devices in the completion of various tasks and was required to use artificial intelligence to decide how individual work stages needed to be completed. These tasks belong to the SUPVIS Justin experiment, which is being carried out as part of the METERON project (Multi-Purpose End-to-End Robotic Operation Network) in cooperation with the European Space Agency (ESA).

In the shadow of the Moon – total solar eclipse visible from the USA

18. August 2017

A total solar eclipse is spectacular for observers: “Around 30 seconds before the Sun disappears entirely behind the Moon, it becomes noticeably darker in the middle of the day, as if someone had quickly turned the dimmer switch for a light,” explains Manfred Gaida, an astrophysicist in the Space Administration team at the German Aerospace Center (DLR), describing the phenomenon. The Moon moves in front of the Sun until just a luminous halo – the corona – can be seen. Where the conical umbra reaches the Earth, the sky goes dark. The partial phase of the eclipse begins around 75 to 90 minutes beforehand, and lasts for the same amount of time after the eclipse, until the ‘all-around twilight’ has completely disappeared.

Varying Martian landscape in Coracis Fossae

10. August 2017

The oldest regions on Mars are often the most interesting as well. Here, numerous traces of geological processes that have altered the planet's surface are visible. The latest images from the high performance HRSC camera show such an ancient area – the Thaumasia Highlands with grabens and mountain ranges.

Active rotor control to reduce noise and vibration

25. July 2017

Under some operating conditions, rotors are the main source of noise produced by a helicopter. To reduce this noise and the simultaneous vibrations, the German Aerospace Centre (Deutsches Zentrum für Luft- und Raumfahrt; DLR), together with Airbus Helicopters Deutschland, has tested active rotor control on a modern, five-blade rotor in a wind tunnel as part of the SKAT (Scalability and risk minimisation of technology) research project. The result was an approximately 30 percent reduction in noise.
