On November the 11th, billions of miles from Earth, a spacecraft orbiter and lander will do what no other has dared to attempt: land on the volatile surface of a comet as it flies round the sun at 41,000 mph. If successful, it could help peer into our past and unlock secrets from our very origins. The stakes couldn't be higher.
