NAVCAM’s shades of grey

Ever since early August, when Rosetta rendezvoused with Comet 67P/Churyumov-Gerasimenko at a distance of roughly 100 km, the on-board navigation camera (NAVCAM) has been returning images that depict the many different facets of its nucleus. A complex...

Name Site J!

ESA and its Rosetta mission partners are inviting you to suggest a name for the site where lander Philae will touch down on Comet 67P/Churyumov–Gerasimenko on 12 November. As the location of the first soft landing of...

Site J (b)

Landing sites from 30 km

With yesterday's announcement that Philae is ‘go’ for Site J, and the presentation of the new primary landing site mosaic, we can provide here the two images that make up the mosaic. The Site J images were taken...

Close-up of the region containing Philae’s primary landing site J. The mosaic comprises two images taken by Rosetta’s OSIRIS narrow-angle camera on 14 September 2014 from a distance of about 30 km. The image scale is 0.5 m/pixel and the image covers about 1 km square. The circle is centred on the landing site and is approximately 500 m in diameter.
