This image was captured on 19 October 2014 and looks across the neck from the comet’s small lobe in the foreground to the large lobe in the background.
Parts of the Anuket and Serqet regions are visible in the foreground and a portion of Hapi is present at centre-left, with the dramatic cliff edge in Seth in the background. There are significant variations in the distances between Rosetta and different parts of the comet in the foreground and background, but the average scale in the image is approximately 77 cm/pixel, yielding a frame width of 785m. The image has been contrast enhanced. Credits: ESA/Rosetta/NAVCAM CC BY-SA IGO 3.0. Larger image

Today perhaps the most anticipated set of NAVCAM images of Comet 67P/Churyumov-Gerasimenko have been released by the Rosetta Downlink & Archive Team via the Archive Image Browser and ESA’s Planetary Sciences Archive.

The 1776 images cover the period between 23 September and 21 November 2014, corresponding to Rosetta’s close study of the comet down to distances of just 10 km from the comet centre 8 km from the surface and the images taken during and immediately following the landing of Philae on the comet.

An animation illustrating Rosetta’s trajectory around this period can be found here, providing context for the range of distances covered by the images in this release. Because of the spacecraft’s proximity to the comet during much of this period, the nucleus overfilled the NAVCAM field of view, and therefore the majority of images are in 2 x 2 rasters to cover the whole comet.

The single frames can certainly be admired individually (see the example above), but they can also be stitched together to create stunning mosaics, as we featured in many of our CometWatch releases from that period. We’re always impressed with the scenes that the image processing fans among you create, and we look forward to seeing what you generate from this release.

In addition to images from the close orbit phase, there are some great gems in this release, such as the NAVCAM’s view of lander Philae shortly after separating from Rosetta on 12 November (below). Although not as detailed as the images captured by Rosetta’s scientific camera OSIRIS, Philae’s body and its three legs can still be made out in a number of NAVCAM images as the lander falls towards the comet.
