The European Space Agency’s (ESA) Rosetta spacecraft was launched on 2 March 2004 and just over ten years later, on 6 August 2014,it arrived at its target, comet 67P/Churyumov-Gerasimenko. On 12 November 2014 the Philae lander was released from the Rosetta spacecraft onto the surface of the comet. Despite a difficult landing Philae has provided valuable data about the composition and physical structure of the comet’s nucleus.
The Rosetta mission was a big success and continues to provide new data about the composition and structure of cometary material. Follow this link to find out more about comets.
