Comet 67P/C-G on 28 March 2015 - NavCam mosaic
Two-image mosaic of comet 67P/Churyumov-Gerasimenko comprising images taken on 28 March 2015 during a close flyby.
Starting at 09:33 UTC four images were taken in sequence by Rosetta's navigation camera (NavCam) as a 2×2 raster over a period of about twenty minutes, meaning that there is some motion of the spacecraft and rotation of the comet between the images. The two images used in this mosaic were the last two in the set (C and D) and taken at an average distance of 19.9 km from the comet's centre. The image scale is about 1.7 m/pixel. The mosaic has been rotated 90 degrees and measures 3.1 × 1.7 km.
Closest approach of less than 14 km from the comet's surface took place at 13:04 UTC.
The image has been cleaned to remove the more obvious bad pixels and cosmic ray artefacts, and intensities have been scaled. Some contrast enhancement has been applied and the vignetting has been fixed. The four individual images and a montage of all four images are also available as related images in the right-hand menu.
More images of comet 67P/Churyumov-Gerasimenko can be found in the '67P - by Rosetta' collection.
