ROLIS – approaching 67P/Churyumov-Gerasimenko in 3D

21. November 2014

Just three kilometres from Comet 67P/Churyumov-Gerasimenko, the ROsetta Lander Imaging System (ROLIS) acquired images of the 'head' and underlying 'body' of Comet 67P. Immediately below is the planned landing site, Agilkia; in the top right of the field of view, one of the landing gear feet can be seen as the camera on the underside of the lander approaches the comet's surface at walking pace.

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.

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.

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.

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.

Philae, the survivalist

14. November 2014

Not only was it the first ever landing on a comet – it was also the second and third. Since 18:32 CET on 12 November 2014, the Philae lander has been on the surface of Comet 67P/Churyumov-Gerasimenko, performing experiments and returning data.

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.

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).

Video: Landing on a Comet – the Rosetta Mission

23. 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.

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.

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.

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.

A long-awaited touchdown: Interview with Stephan Ulamec

15. September 2014

In this interview, Stephan Ulamec, project manager for Philae, explains what lies ahead for the lander and the risks involved with a mission that has never been attempted.

Live webcast of the landing site announcement for Philae

15. September 2014

Since Rosetta arrived at Comet 67P/Churyumov-Gerasimenko, scientists have been searching for a suitable landing site on the nucleus for the Philae lander. On 25 August 2014, five candidate landing sites were selected. After close examination, today, on 15 September, the primary landing site and a backup will be announced.

Spoilt for choice – five candidate landing sites on Comet 67P/Churyumov-Gerasimenko

25. August 2014

Never before did a mission team have to select a landing site on a comet – the Philae lander will be the first spacecraft ever to land on a comet and conduct in situ measurements. The ESA Rosetta spacecraft and the Philae lander began their journey to their final destination – comet 67P/Churyumov-Gerasimenko – 10 years ago.

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.
