Rosetta mission: Philae's landing site on comet 67P – in pictures

Rosetta’s lander Philae is safely on the surface of Comet 67P/Churyumov-Gerasimenko, as these first two CIVA images confirm. One of the lander’s three feet can be seen in the foreground. The full panoramic from CIVA will be delivered in this afternoon’s press briefing at 13:00 GMT/14:00 CET.

First comet panoramic Rosetta s lander Philae has returned the first panoramic image from the surface of a comet. The view, captured by the CIVA-P imaging system, shows a 360 view around the point of final touchdown. Parts of Philae s landing gear can be seen in some of the frames. Confirmation of Philae s touchdown on the surface of Comet 67P/Churyumov Gerasimenko arrived on Earth at 16:03 GMT/17:03 CET on 12 November. Credit: ESA/Rosetta/Philae/CIVAfromme
This panoramic image series shows the wall of rock in front of Philae, captured by its ÇIVA-P imaging system. Six identical micro-cameras are designed to take pictures of the surrounding surface. A spectrometer then studies its composition, texture and albedo (reflectivity).

Using the same panoramic image series, the Philae lander team have superimposed a sketch showing their best guess for the orientation of the craft relative to its surroundings.



Another stunning image of my new home taken by ROLIS during #CometLanding yesterday, when I was just 40 m from #67P.
Philae tweeted on Thursday morning: ‘Another stunning image of my new home taken by ROLIS during #CometLanding yesterday, when I was just 40 m from #67P.’



This five-image montage of narrow-angle images taken by the OSIRIS camera is being used to try to identify the final touchdown location of Philae. The images were taken around the time of landing on Wednesday when Rosetta was about 16 kilometres from the surface of Comet 67P/Churyumov-Gerasimenko.
This five-image montage from the OSIRIS camera is being used to identify the final touchdown site. The images were taken around the time of landing on Wednesday when Rosetta was about 16 kilometres from the comet surface. They are overexposed – subsequent images will be more accurately exposed, making it easier to spot the lander, say scientists


This image shows an OSIRIS narrow-angle image taken from a distance of 30 km on 14 September 2014 (prior to landing) marks the first touchdown point of the Philae lander.The signal confirming landing arrived on Earth at 16:03 GMT (17:03 CET). It is thought that Philae bounced twice before settling on the surface of Comet 67P/Churyumov-Gerasimenko.The lander has not yet been identified and images are still to be downloaded from the Rosetta spacecraft for further analysis.
The lander has not yet been located. This image was taken by OSIRIS back in September. The cross-hairs show the location where Philae first hit the ground – almost exactly at the intended target. Two slow-motion bounces followed



This OSIRIS wide-angle camera image shows the position of Rosetta's lander Philae (circled) at 14:19:22 GMT (onboard spacecraft time).Separation occurred onboard the spacecraft at 08:35 GMT (09:35 CET), with the confirmation signal arriving on Earth at 09:03 GMT (10:03 CET).The signal confirming touchdown arrived on Earth at 16:03 GMT (17:03 CET).

A picture taken with the CIVA camera on Rosettas Philae lander showing comet 67P/ChuryumovGerasimenko from a distance of about 16 km from the surface of the comet. The 'selfie' image was taken on October 7, 2014 and captures the side of the Rosetta spacecraft and one of Rosettas 14 m-long solar wings, with the comet in the background. Two images with different exposure times were combined to bring out the faint details in this very high contrast situation. The comet's active neck region is clearly visible, with streams of dust and gas extending away from the surface.
