The tell-tale radiation from metallic asteroids

2. April 2014

In the process of evaluating thousands of datasets from the NASA Wide-field Infrared Survey Explorer (WISE) space telescope, planetary researchers at DLR have been tracking metallic asteroids.

Philae lander back in contact with Earth

28. March 2014

More than two and a half years – this is how long the Philae lander has been hibernating while travelling through space on board the European Space Agency ESA Rosetta spacecraft. On 28 March, the lander was successfully reactivated and broke its planned radio silence by sending data to Earth from a distance of about 655 million kilometres.

'Living on Mars' – for four months

27. March 2014

Lucie Poulet said goodbye to the outside world for four months when the door closed behind her on 28 March 2014; the scientist from DLR is participating as a crewmember in a Mars simulation run by the University of Hawaii at Manoa.

Philae

Philae lander – nearing the end of hibernation

26. March 2014

A rocket launch in March 2004, multiple swing-bys past Earth and Mars, high-speed fly-bys of asteroids Šteins and Lutetia – after all this, the Philae lander on board ESA's Rosetta spacecraft, which is en route to Comet 67P/Churyumov-Gerasimenko, is in good shape.

DLR Magazine 140-141 - Entering the home straight

25. March 2014

The spring issue of the DLR Magazine allows its readers to join Alexander Gerst as he completes preparations for the 'Blue Dot' mission, which will run for six months, starting on 28 May 2014, on the International Space Station.

Ice clouds as a climate factor – research aircraft HALO examines cirrus clouds and vapour trails

24. March 2014

Unanswered questions about the formation of clouds and their impact on the climate are currently setting limitations on the validity of global climate forecasts. To make a detailed analysis of the climate effects of natural ice clouds and the vapour trails created by air traffic, the HALO research aircraft embarked on the first of a total of 12 measurement flights on 24 March 2014.

Paper plane champion – DLR aviation researcher Kai Wicke

13. March 2014

He is the German paper plane champion, having achieved the longest flight, and has already flown a glider high over Australia. The passionate and vastly experienced competitive glider pilot discovered his love of the sport and of flying in general early on.

Ask astronaut Alexander anything

11. March 2014

German European Space Agency (ESA) astronaut Alexander Gerst is all set for the 'Blue Dot' mission to the International Space Station in May. Crewmates NASA astronaut Reid Wiseman and commander-cosmonaut Maxim Surayev will hold a media conference on Tuesday 18 March 2014 and ESA is inviting you to ask questions via Twitter.

Lavaströme am Fuß des Mistretta%2dKraters auf dem Mars

Lava flows at the foot of Mistretta Crater

6. March 2014

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 extent to which volcanism has shaped the surface of Mars.

LADEE

Laser beam from the Moon to Earth

5. March 2014

By the time the signal is analysed by scientists at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), it will have travelled roughly 400,000 kilometres and passed through Earth's atmosphere.

Quiet and fuel-efficient landing – simulator tests for a new pilot assistance system

28. February 2014

For new, quieter descent procedures, pilots must adhere precisely to a predetermined sequence of actions during the landing phase. DLR has developed a pilot assistance system that optimises landings, making them safer, quieter and more fuel-efficient.

PLATO

Space telescope PLATO 2.0 to search for a 'second Earth'

19. February 2014

Situated at a favourable, stable distance from its star and having liquid water on its surface – this is what the planets that scientists involved in the Planetary Transits and Oscillations of Stars (PLATO) mission seek to discover outside of the Solar System. An international consortium under the leadership of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) will search for this 'second Earth'. The space telescope that the European Space Agency (ESA) selected from among five proposed missions on 19 February 2014 is scheduled to launch in 2024. "This unique European space telescope, designed to search for exoplanets, will enable German and European scientists to engage in truly cutting-edge research in this field of astronomy," says DLR Executive Board Chairman Johann-Dietrich Wörner.

Life of an astronaut – Alexander Gerst's blog

17. February 2014

In 100 days, German ESA astronaut Alexander Gerst will be launched to the International Space Station ISS with NASA astronaut Reid Wiseman and cosmonaut commander Maxim Surayev.

The broken surface of Mars at Claritas Fossae

The broken surface of Mars at Claritas Fossae

13. February 2014

Recent images acquired with the High Resolution Stereo Camera (HRSC), operated by DLR on board the European Space Agency Mars Express spacecraft, show a portion of the Claritas Rupes escarpment on Mars that surrounds the Claritas Fossae graben system. It forms the eastern boundary of the gigantic Tharsis volcanic region, where the biggest volcanoes on Mars are located.

Unique wind tunnel test for slower landing approaches

Unique wind tunnel test for slower landing approaches

12. February 2014

Slower landing approaches by aircraft lead to less noise. How slow, steep and hence quiet a modern commercial aircraft can arrive at a destination airport is determined by the performance of the high-lift system with its retractable slats and flaps on the wings. Another advantage of reduced landing speeds is that shorter runways can be used. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has joined with Airbus, and the European Transonic Wind Tunnel (ETW) in the three-part project HINVA (High lift INflight VAlidation), consisting of wind tunnel experiments, flight tests and computer simulations. The aim is to combine computer models and wind tunnel tests to substantially improve predictions of high-lift performance and hence pave the way for slower and quieter approach flights. In early February, the project performed unique wind tunnel experiments at cryogenic temperatures in the ETW in Cologne. Equipped with laser measurement technology and other advanced measurement systems, the researchers achieved hitherto unknown precision in detecting the flowfield around an Airbus A320 with extended landing flaps and slats under flight-representative conditions. The researchers had constructed a high precision wind tunnel model specifically for the tests, based on flow measurements performed during in-flight tests with the DLR A320 ATRA research aircraft.

Fastest glacier in Greenland – DLR satellites TerraSAR-X and TanDEM-X identify speed record

3. February 2014

Since the 1990s, Jakobshavn Isbræ has been regarded as the fastest moving glacier in Greenland. According to studies carried out by researchers from the University of Washington and DLR, its speed is now increasing dramatically, with record figures for 2012 and 2013.
