Philae

Philae's triple play

20. November 2014

A short but significant 'thud' was heard by the Cometary Acoustic Surface Sounding Experiment (CASSE) as Philae made its first touchdown on Comet 67P/Churyumov-Gerasimenko. The two-second recording from space is the very first of the contact between a man-made object with a comet upon landing.

MUPUS

Philae on 67P – MUPUS experiment hammers probe into a comet 500 million kilometres from Earth

18. November 2014

The MUPUS instrument, one of 10 experiments on the Philae lander that touched down on comet 67P/Churyumov-Gerasimenko encountered very hard material with a temperature of about minus 170 degrees Celsius – probably rich in ice.

Age of star nursery precisely determined for the first time

17. November 2014

How long does it take for a star to be born? To date, only this much has been clear: longer than there have been humans on Earth with the technology to observe it. But the precise age of a star-forming cloud has now been determined by a team under the leadership of scientists at the University of Cologne using the GREAT spectrometer on board the SOFIA airborne observatory.

Churyumov-Gerasimenko – hard ice and organic molecules

17. November 2014

Before going into hibernation at 01:36 CET on 15 November 2014, the Philae lander was able to conduct some work using power supplied by its primary battery. With its 10 instruments, the mini laboratory sniffed the atmosphere, drilled, hammered and studied Comet 67P/ Churyumov-Gerasimenko while over 500 million kilometres from Earth.

ATV technology for the new Orion space capsule

17. November 2014

Construction of the International Space Station (ISS) started on 20 November 1998 with the launch of the Russian cargo and propulsion module 'Zarya' (Dawn).

Lander Control Center (LCC)

Philae lander shortly before hibernation

15. November 2014

Update – the Philae lander entered sleep mode at 01:36 CET on 15 November 2014. The Philae lander performed about 56 hours of continuous scientific measurements on the surface of Comet 67P, but by 01:15 CET on 15 November the energy state of the lander became so low that the engineers assumed that Philae would go into sleep mode during the night.

Willkommen auf Komet 67P!

Welcome to a comet

13. November 2014

Rosetta's lander Philae is safely on the surface of Comet 67P/Churyumov-Gerasimenko, as these first two CIVA images confirm.

ROLIS-camera takes closest picture of Churyumov-Gerasimenko

12. November 2014

The image shows comet 67P/CG acquired by the ROLIS instrument on the Philae lander during descent on Nov 12, 2014 14:38:41 UT from a distance of approximately 3 km from the surface.

Visit to Comet 67P – Philae has landed

12. November 2014

On 12 November 2014, the Philae lander touched down on the surface of Comet 67P/Churyumov-Gerasimenko. This is the first time a man-made device has landed on a comet and collected data directly from the surface.

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.

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.
