On Wednesday, November 12th, an unmanned spacecraft made history by landing perfectly on its target - a speeding comet that lies at a distance of 310 million miles from earth. According to the European Space Agency (ESA), the brainchild behind this audacious project, the Rosetta space probe that housed the 220-pound washing machine-sized Philae lander, released its passenger to its destination perfectly - not an easy feat given that the Comet 67P was hurtling through Space at a speed of 41,000 mph.
