Space history is being made in our solar system this summer as ESA’s Rosetta spacecraft catches up with a comet and begins to orbit around it for the very first time. The space probe has spent a decade flying around the planets, gaining enough speed and the right trajectory to rendezvous perfectly with the icy mass of comet 67P/Churyumov-Gerasimenko. This week it moves into position, and becomes the first man-made object ever to fly alongside a comet as it speeds towards the Sun, grabbing some stunning photographs and revealing science data in the process.
