Thermal protection layer destroyed, sensors blocked

Volcanic ash can cause serious problems for aviation. Under Project VolcATS-Vehicle, researchers from DLR are investigating the effects of volcanic ash on aircraft.

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.

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.

The search for the 'perfect' landing site

21. August 2014

When the Philae lander reaches its landing site on Comet 67P/Churyumov-Gerasimenko, it needs to be at a level yet scientifically interesting location, with enough sunlight and the right conditions to ensure a long working life. However, the rugged, unusually shaped comet is not making the choice easy for the lander team.

Approaching Comet Churyumov-Gerasimenko

31. July 2014

Less than 2000 kilometres separate the ESA orbiter Rosetta and the Philae lander from their destination, Comet 67P/Churyumov-Gerasimenko. Images acquired with the OSIRIS camera system already indicate what lies ahead for the orbiter and lander upon arrival: "The surface seems pretty rough. We will have to wait to determine whether the visible depressions are impact craters or structures produced by cometary activity," says Ekkehard Kührt from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR). The comet researcher is involved in the acquisition of data by the OSIRIS camera and is also responsible for data analysis. Another image taken by the camera shows that a cloud of dust, the coma, enshrouds the comet. “As we draw closer to Churyumov-Gerasimenko, the other instruments used in the mission will provide us with interesting insights into the interaction between the dust and the surrounding gas.”

Survivalists ready for journey to the ISS

22. July 2014

Tough, resilient and able to survive in the most inhospitable regions on Earth –now, they are being asked to show their strength in a space environment as well; blue-green algae (cyanobacteria of the genus Nostoc) and biofilms (deinococcus geothermalis) will depart for the International Space Station (ISS) at 23:44 CEST on 23 July 2014 on board a Progress spacecraft.

Comet Churyumov-Gerasimenko – neither ball nor potato

17. July 2014

Comets have irregular and rather potato-like shapes – this is a well-known fact. But the comet 67P/Churyumov-Gerasimenko, on which the Philae lander is scheduled to descend in November 2014, has an unexpected shape.

'Blue Dot' – Alexander Gerst's mission to space

9. May 2014

The final exam in Russia has been passed, four and a half years of astronaut training across the globe are complete – and now, less than three weeks remain until the astronaut Alexander Gerst loses the ground under his feet for six months.

Eu:CROPIS – Growing tomatoes in space

24. April 2014

A symbiotic community of bacteria, tomatoes and single-celled algae, synthetic urine and a satellite that simulates the gravity of the Moon or Mars by rotating around its axis – these elements make up the German Aerospace Center (Deutsches Zentrum für Luft und- Raumfahrt; DLR) Eu:CROPIS (Euglena and Combined Regenerative Organic-Food Production in Space) mission.
