Interview with Svetlana Gerasimenko – 'Beginner's luck'

11. November 2014

In 1969, Svetlana Gerasimenko and Klim Churyumov discovered the comet that the Philae lander will descend to on 12 November 2014.

EML furnace performs test run on the Space Station

10. November 2014

Even before its scientific use on the International Space Station (ISS), a stubborn bolt and complex assembly tasks in space made the Electromagnetic Levitator (EML) a particularly challenging experiment.

Welcome back Alexander! – German ESA astronaut back on Earth

10. November 2014

German ESA astronaut Alexander Gerst is back on Earth after spending five and a half months in space. The 38-year-old geophysicist and flight engineer landed in the steppes of Kazakhstan roughly 100 kilometres from the city of Arkalyk at 04:58 CET (09:58 local time) on 10 November 2014 after a three and a half hour return journey on board a Russian Soyuz spacecraft.

A challenge – the first landing on a comet

7. November 2014

The Philae lander on board the Rosetta spacecraft has been en route to its destination, Comet 67P/Churyumov-Gerasimenko, since 2 March 2004. On 12 November 2014, it will be released from its mother craft at an altitude of 22.5 kilometres above the comet and – if everything goes according to plan – will touch down on the surface of the comet about seven hours later.

Philae landing site J is now named 'Agilkia'

4. November 2014

Egyptian history has been explored, new words invented and appropriate comparisons sought for; a total of about 8300 suggestions for Philae’s landing site on Comet 67P/Churyumov-Gerasimenko were received at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), the French Space Agency (Centre National d'Etudes Spatiales; CNES) the Italian Space Agency (Agenzia Spaziale Italiana; ASI) and the European Space Agency (ESA).

Comet Siding Spring imaged by HRSC on board Mars Express

3. November 2014

Comet Siding Spring came extraordinarily close to Mars on 19 October 2014. The celestial body - a mere 500 metres in diameter - passed the Red Planet at a distance of just 137,000 kilometres, where it was observed by several spacecraft in orbit around Mars.

Fifteen years of science in a parabolic flight aircraft – Airbus A300 ZERO-G goes into retirement

31. October 2014

The Airbus A300 ZERO-G has completed 5200 flights, 4200 flying hours and 13,180 parabolas in the service of science and microgravity research. Now, the parabolic flight aircraft, operated by French company Novespace, is bowing out into well-earned retirement following the 25th research campaign for DLR.

Video: Landing on a Comet – the Rosetta Mission

17. October 2014

After a 10-year journey of some seven billion kilometres, the Rosetta mission is now heading towards its next major milestone – setting the lander Philae on a comet.

3D flight over Hydraotes Chaos on Mars

16. October 2014

Among the most interesting landforms on Mars are features referred to as 'chaotic terrain'. Dozens or even hundreds of isolated mountains up to 2000 metres high are scattered in these extensive regions. Seen from orbit, they form a bizarre, chaotic pattern.

Selfie aus 16 Kilometern Entfernung vom Kometen

Mission 'selfie' from 16 kilometres

14. October 2014

This mission ‘selfie’ was taken on 7 October at a distance of approximately 16 kilometres from the surface of Comet 67P/Churyumov-Gerasimenko by the CIVA imaging system on board Rosetta’s lander, Philae.

TanDEM-X – Start of the Science Phase of the mission

10. October 2014

The radar satellite TerraSAR-X has been orbiting the Earth since June 2007; in June 2010 its twin, TanDEM-X, followed it into space. For almost four years, the two satellites have been operated in a close flight formation by DLR.

Timetable for comet landing on 12 November 2014 – Philae’s descent onto 67P/Churyumov-Gerasimenko

26. September 2014

In mid September, the site where the Philae lander will touch down on Comet 67P/Churyumov-Gerasimenko was selected – landing site 'J'. Now, there is a detailed timetable for the descent of Philae. The lander will undock from the Rosetta spacecraft at 09:35 CET on 12 November 2014 at a distance of approximately 22.5 kilometres from the centre of the comet and land on the surface about seven hours later.

Radar remote sensing – research for agriculture and climate

19. September 2014

The 2014 harvest season is coming to an end, and throughout Germany the signs are of good yields for wheat, corn and similar crops. But the differences are large depending on the location. Hence, for optimum cultivation, it is important to be constantly aware of the condition of the soil and the crops. Radar images are particularly suitable for providing large-scale observations – using an aircraft or a satellite.

Bodenfrost im Krater Hooke auf dem Mars

Deep winter in Argyre Planitia

18. September 2014

On 20 April 2014, the High Resolution Stereo Camera (HRSC) on the ESA Mars Express spacecraft, which is operated by DLR, imaged the northern part of the enormous Argyre Planitia impact basin in the southern hemisphere of Mars. At that time, it was deep winter in the area, as can easily be seen from the ground frost covering the interior of Hooke Crater and large sections of the landscape in the image.

TerraSAR%2dX%2dBild zeigt Ausbreitung der Lava am Bardarbunga

TerraSAR-X image shows spread of lava at Bardarbunga

16. September 2014

The lava outflow on the Holuhraun field northeast of Iceland's Bardarbunga volcano continues unabated. The lava field has grown to cover an area greater than 25 square kilometres.

Lander Philae: Sonniger Landeplatz auf dem Kometenkopf

Philae lander – sunny landing area on the comet 'head'

15. September 2014

When the Philae lander touches down on 11 November 2014, Comet 67P/Churyumov-Gerasimenko will have a landing site waiting for it with a varied but not too rugged landscape offering good solar illumination and hardly any steep slopes. In a two-day selection process, the lander team under the leadership of DLR selected landing site 'J' from among five possible candidates.

New measurements every day – Bardarbunga sulphur dioxide cloud

12. September 2014

The Bardarbunga volcano on Iceland began erupting on 31 August 2014 – an effusive eruption with no ejection of volcanic ash. However, measurements made by DLR have since indicated that there is ongoing emission of sulphur dioxide (SO2). High sulphur dioxide concentrations in the atmosphere are a clear indication of volcanic activity, as there are no other natural emission sources, only anthropogenic ones.

Lucie Poulet

Return from a virtual Mars mission

10. September 2014

Lucie Poulet, from DLR, spent four months living 'on Mars', donning a spacesuit to explore the Red Planet and cultivating vegetables inside the domed Mars station. To do all this, she did not have to move away from her home planet, Earth.

Bubble-free pumping of liquids in space

10. September 2014

Pumping fuel with no bubbles is no problem at the filling station around the corner, but it certainly is in the microgravity environment of space. The fourth and final series of the Capillary Channel Flow (CCF) experiments on the International Space Station (ISS), which began on 5 August 2014, has just come to an end.

A volcano comes to life – satellite picture of Bardarbunga on Iceland

10. September 2014

Bardarbunga, (Bárðarbunga) in Iceland, one of the largest volcanoes in Europe and located beneath the biggest glacier in Europe, became active again in mid-August. For several years now, DLR researchers have been keeping a close eye on Bardarbunga and the system of volcanoes associated with it – an enormous network of subterranean magma channels, vents and craters.
