Four spacecraft in one view, taken on 9 December 2018. ESA astronaut Alexander Gerst posted this image during his Horizons mission from the International Space Station. He commented: "A rare sight: four different spaceships in one photo. Overall there are six spacecraft docked to the International Space Station right now, to utilise this unique laboratory to the max. Two Soyuz, Two Progress, a Cygnus and a Dragon."
