A trio of the closest NAVCAM images of Comet 67P-Churyumov Gerasimenko is featured as our ESA Space Science Image of the Week.
During the last few weeks of its mission at Comet 67P/C–G, the Rosetta spacecraft ventured closer than it had ever been to the surface of the nucleus. Eventually, it came to rest on the small lobe of the comet in a daring descent on 30 September 2016. No navigation images were taken during the descent; the last five NAVCAM images were taken several hours earlier, between about 20 and 17 km from the comet centre.
This montage features the three closest images of the comet's surface taken by Rosetta's navigation camera – acquired in the first half of September.
The left image in the composite (also shown below) was taken on 8 September, some 2.6 from the comet surface.
Enhanced NAVCAM image of Comet 67P/C-G taken on 8 September 2016, 4.3 km from the comet centre and about 2.6 km from the surface. The distance from Rosetta to the closest pixel in this image is 2.3 km. The scale is 0.2 m/pixel and the image measures about 225 m across. Credits: ESA/Rosetta/NAVCAM – CC BY-SA IGO 3.0
