Closing in on Rosetta's target comet
Surface structures are becoming visible in new images of the comet 67P/Churyumov-Gerasimenko. These images, with a resolution of 100 metres per pixel, were acquired with the OSIRIS scientific imaging system on board Rosetta. The comet's neck region – the section connecting the two heads – seems to be much brighter than the head and body of the nucleus.##markend##
Images acquired recently have shown that the comet may consist of two interconnected parts: a smaller 'head' and a larger 'body'. The latest images show the neck connecting the two sections. It is particularly interesting for the scientists because it appears brighter than the rest of the comet. Possible reasons for this could be differences in the surface composition or the structure of the surface material.
ESA's Rosetta spacecraft will reach the comet on 6 August 2014 and the Philae lander is scheduled to land on the comet's surface in November.
