Rosetta comet mission: What is 67P? The European Space Agency is hoping to make history by landing a probe on a comet 500 million km from Earth. Esa's Rosetta satellite will despatch its piggybacked Philae probe to the surface of the "ice mountain" - known as 67P/Churyumov-Gerasimenko - on the morning of 12 November. Here's a quick look at the comet - and what it could teach us - in 60 seconds. Video produced by Michael Hirst, video footage courtesy of European Space Agency
