I wish I knew things.

more pictures from the close flyby have been released including



14 February close flyby
Close view of a 228 x 228 m region on Comet 67P/Churyumov-Gerasimenko, as seen by the OSIRIS narrow-angle camera during Rosetta’s flyby at 12:39 UT on 14 February 2015. The image was taken six kilometres above the comet’s surface, and the image resolution is just 11 cm/pixel. Rosetta’s fuzzy shadow, measuring approximately 20 x 50 metres, is seen at the bottom of the image.

an article from the daily mail explains why the shadow in above pictures is so 'fuzzy' -> http://www.dailymail.co.uk/sciencetech/article-2978275/Rosetta-glimpses-shadow-Probe-dips-close-comet-67P-selfie-spots-strange-alien-halo.html


This graphic shows the difference between how a sharp shadow is generated by a point source (left) and a fuzzy shadow by a diffuse source (right)

Space is wicked.

now some picture from the journey around the comet
