\nThis view highlights the distinctive flat feature set atop a raised plateau on the larger lobe of Comet 67P\/Churyumov\u2013Gerasimenko. In several locations close to the base of this feature, there are patches of brighter material, perhaps recently exposed by erosion.
\nThis single-frame NAVCAM image measures 1024 x 1024 pixels. It was captured from a distance of 9.8 km from the centre of the comet (7.8 km from the surface) at 11:48 GMT on 24 October 2014. At this distance, the image resolution is 83.3 cm\/pixel and the size of the image is 854 x 854 m.<\/p>\n

\nThis view focuses on the boulder-strewn neck region of Comet 67P\/Churyumov\u2013Gerasimenko, with the smaller lobe on the left and the larger lobe on the right. Much of the comet\u2019s activity originates from the neck. The scene also shows the contrast between the rugged material in the cliff walls rising up to the smaller lobe and the soft, more \u2018textured\u2019 material that characterises the neck and that is also coating the larger lobe in this region.
\nThis single-frame NAVCAM image measures 1024 x 1024 pixels. It was captured from a distance of 9.7 km from the centre of the comet (about 7.7 km from the surface) at 06:22 GMT on 28 October 2014.

\nThis view looks from the smaller of Comet 67P\/Churyumov\u2013Gerasimenko\u2019s two lobes (foreground in lower left) over to the larger lobe, which occupies most of the frame and which is dominated by rubble-filled depressions. One, just to the right of centre in the lower part of the image, has a near-circular appearance. It is expected that some circular pits on the comet are associated with the source of activity, perhaps as gas vents from the comet\u2019s porous interior. Whether this is such a feature is yet to be confirmed.

\nIn this scene from the large lobe of Comet 67P\/Churyumov\u2013Gerasimenko, sets of long, parallel grooves and ridges in the foreground draw the eye up to a block of layered material (appearing as vertically stacked layers in this orientation) in the centre of the frame. This ridge traces up to a peak in the distance, through a cascade of boulders. To the left, flat-topped steps contrast against a \u2018pinnacle\u2019 seen against the horizon. To the right, a patch of brighter material lies crumbled at the base of a steep wall \u2013 perhaps signalling material that has been freshly exposed.
\nIn a different orientation, the \u2018peak\u2019 actually appears as a flat ridge that slopes down onto a flat plateau, showing the importance of viewing features from different angles in order to understand them fully.

\nBoulders seem to defy gravity in this view, apparently clinging to the steep sides of the larger lobe of Comet 67P\/Churyumov\u2013Gerasimenko, although of course it is all a matter of the orientation of the image and the local gravity vector. But perhaps the most intriguing feature in this frame is on the right-hand side, where thin layers of rock have the appearance of being flexed or compressed. This feature sits close to the \u2018neck\u2019 of the comet, which can be seen in the background rising up towards the smaller of the comet\u2019s two lobes.
\nOne theory for the comet\u2019s formation is that two smaller bodies collided to create the comet shape we see today. Whether this layered feature is due to such a scenario or a completely different process remains to be seen.

\nThis scene features the boulder named Cheops, the largest and brightest boulder towards the top left of the image. It measures about 45 m across and 25 m high. Cheops and the surrounding cluster of boulders reminded scientists of the famous pyramids at Giza near Cairo in Egypt, and so it was named for the largest of those pyramids, the Great Pyramid, which was built as a tomb for the pharaoh Cheops around 2550 BC.
\nAnother large boulder lies towards the bottom of this frame and is surrounded by many smaller boulders that seem to be appearing from beneath the smooth, dusty material that dominates this scene. The smooth region extends to the top right of this frame, where rougher terrain appears to be exposed beneath it.

\nThis image showcases one of the many pits seen on the surface of 67P\/Churyumov\u2013Gerasimenko. Pits like these are thought to be where gas vents into space from the porous subsurface, carrying with it dusty grains of comet material. Scientists are keen to learn the role of this pit \u2013 and others \u2013 in the development of the comet\u2019s activity, as it gets ever closer to the Sun.

\nThis scene presents a dramatic view across the body of the large lobe of Comet 67P\/Churyumov\u2013Gerasimenko. Along the horizon a relatively broad, raised portion of material appears to be abruptly truncated in the top left. Zooming into either side of the inner portion of the wall suggests the presence of slightly brighter material \u2013 perhaps more recently exposed than other sections.. Although cast in shadow, the sides of the raised section shows signs of clear layering, along with fractures cross-cutting in many orientations.
\nIn the foreground, several large angular blocks are seen, some with faces that appear brighter than the surrounding material. In the background, a faint stream of gas and dust can be seen, showing that an active region is nearby.

\nThis dramatic view along the horizon highlights several relatively smooth, flat-topped plateaus that stand above the rugged surface on the larger lobe of Comet 67P\/Churyumov\u2013Gerasimenko. But their flat tops betray the scars of the walls just below, extensively criss-crossed with fracture-like features. At their bases lies plentiful rubble, perhaps once originating from the cliff faces, having crumbled away under the erosive forces at work on the comet.

Agilkia landing site, 6 November 2014<\/strong>
\nThe Agilkia landing site is seen on this image of Comet 67P\/Churyumov\u2013Gerasimenko, taken with Rosetta\u2019s navigation camera on 6 November, just days before its lander Philae makes its historic descent to the surface.
\nThe image presented here is a mosaic of four individual NavCam frames, captured from a distance of 30.5 km from the comet centre on 6 November while Rosetta was en route to the separation trajectory from which it will deploy Philae on 12 November. At this distance, the image scale is 2.6 m\/pixel, and the mosaic measures 3.7 x 3.3 km.
\nThe landing site, covering about one square kilometre, is located close to the top of this image, above the easily recognisable, boulder-filled depression that characterises the smaller of the comet\u2019s two lobes. Although it may not seem like it from this image, Agilkia \u2013 previously known as Site J \u2013 presented the least hazardous terrain of all the landing sites considered during the selection process.
