On 6 August of 2014, after a decade of travelling through interplanetary space, ESA’s Rosetta spacecraft arrived at its final target: Comet 67P/Churyumov-Gerasimenko (67P/C-G). The mission was the first to successfully land on a comet when it sent the lander Philae down to the surface a few months later, while the orbiter studied 67P/C-G in detail before the mission’s end on 30 September 2016.
