The European comet chaser, Rosetta, shot this legendary ‘selfie’ on 7 October 2014. In the foreground you can see its Dutch-built solar panels. In the background is the mission’s destination: Comet 67P/Churyumov-Gerasimenko. At the time the photo was taken, the distance to the comet surface was just sixteen kilometres. Rosetta had already completed a ten-year journey of more than six billion kilometres.
