摘要
描述Comet 67P on 19 September 2014 NavCam montage.jpg |
English: Montage of four images taken by Rosetta's navigation camera (NAVCAM) on 19 September 2014 at 28.6 km from the centre of comet 67P/Churyumov-Gerasimenko. The four images were taken in sequence as a 2×2 raster over an approximately 20 minute period, meaning that there is some motion of the spacecraft and rotation of the comet between the images.
The images have been cleaned to remove the more obvious bad 'pixel pairs' and cosmic ray artefacts, intensities have been scaled. The dark feature in the centre is an imaging artefact. The four individual full-frame images are also available as related images in the right-hand menu. A mosaic of the four images stitched together is available here. |
