Headache for Philae

20. July 2015

On 9 July 2015 at 19:45 CEST, Philae reported back to the team at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Lander Control Center (LCC) – only to then go back to 'silent mode'. Since then, the team has been working hard to get back in contact with the lander and operate it to conduct scientific measurements.

New communication with Philae – commands executed successfully

10. July 2015

The Philae lander communicated with the Rosetta orbiter again between 19:45 and 20:07 CEST on 9 July 2015 and transmitted measurement data from the COmet Nucleus Sounding Experiment by Radiowave Transmission (CONSERT) instrument. Although the connection failed repeatedly after that, it remained completely stable for those 12 minutes.

DLR and Canadian National Research Council announce closer cooperation in aeronautics research

9. July 2015

Collaboration between them is already a reality, but with the signing of a framework cooperation agreement on 9 July 2015, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and the National Research Council of Canada (NRC) have now strengthened their cooperation. Current research projects will be extended in the next five years – for example, in the area of alternative aircraft fuels – and new cooperation projects will be embarked upon to facilitate, among other things, uncrewed aerial vehicles (UAV) and aircraft cabin research.

MAPHEUS-5 – liftoff inside the Arctic Circle

30. June 2015

The German Aerospace Center's (Deutsches Zentrum für Luft- und Raumfahrt; DLR) mobile rocket base MORABA launched the MAPHEUS-5 high-altitude research rocket at 06:55 CEST on 30 June 2015, carrying four DLR experiments on board. The 12-metre-high, two-stage rocket took off from the Swedish Esrange Space Center and ascended to an altitude of 253 kilometres – taking only 74 seconds to reach a state of microgravity lasting over six minutes, which was used to conduct experiments from the fields of material physics and biology.

'SpaceCOT' study – conditions like those on the International Space Station

30. June 2015

For 28 hours, six subjects will remain lying down and tilted at 12 degrees so their heads are lower than their legs. At times, they live and sleep in a carbon dioxide enriched atmosphere. With the 'SpaceCOT' study, researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and the US National Space Biomedical Research Institute (NSBRI) are investigating how the human brain and eyes are affected by the shift of body fluids towards the head as well as the increased carbon dioxide content in the air.

Philae

Contact with Philae still irregular and unstable

26. June 2015

Despite a new trajectory for Rosetta and a reduction of the distance between the orbiter and Comet 67P/Churyumov-Gerasimenko from 200 to 180 kilometres, contact with the Philae lander remains irregular and short. After the initial contact on 13 June 2015, Philae has reported to the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Lander Control Center (LCC) in Cologne a total of six times.

Using solar energy to melt aluminium – German and South African researchers develop new method

17. June 2015

South Africa has plentiful solar energy and, at the same time, possesses a large aluminium processing industry. Researchers and industry are cooperating within the SOLAM (solar melting of aluminium in a directly radiated rotary kiln) project to develop a method by which aluminium foundries could use solar energy to melt this metal.

Lander Philae is awake – 'Hello' from space

14. June 2015

The Philae lander has reported back on 13 June 2015 at 22:28 (CEST), coming out of hibernation and sending the first data to Earth. More than 300 data packets have been analysed by the team at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Lander Control Center: "Philae is doing very well – it has an operating temperature of minus 35 degrees Celsius and has 24 watts of power available," explains DLR’s Philae Project Manager, Stephan Ulamec. "The lander is ready for operations." Philae 'spoke' for 85 seconds with its team on ground in its first contact since it went into hibernation.

The search for Philae – like a needle in a haystack

11. June 2015

On 15 November 2014 at 01:15 CET, Philae's battery was exhausted and, after nearly 60 hours of operation on Comet 67P/Churyumov-Gerasimenko, the lander went into hibernation – in an unexpected place. Philae 'bounced' several times before landing in its current location, and its exact position has still not been determined.

DLR study – inclusion of aviation in international climate protection protocols

23. April 2015

Aviation and the impact it can have on the climate can be integrated into international climate protection protocols. This would enable significant reductions in climate-related emissions and associated impact, with a modest effect on the demand for air transport.
