After a 64 billion kilometer journey a robotic space probe has landed on a comet for the first time in history.

The Philae probe touched down on comet 67P last night to the jubilation of mission controllers at the European Space Agency, who launched the probe on board the Rosetta spacecraft more than ten years ago.
