After an amazing ten year journey, the Rosetta mission landed its module Philae on the surface of Comet 67P/Churyumov–Gerasimenko at 16:03 GMT on Wednesday.

Rosetta was launched on 2 March 2004 on an Ariane 5 rocket, and has already made history by becoming the first spacecraft to orbit a comet after it reached its long-awaited destination on August 6th 2014.
