Billions of kilometers from Earth, a spacecraft the size of a car traveled towards an icy rock 2.5 miles across hurtling through space at tens of kilometers per second. It had been in space for ten years, but on Nov. 12, 2014 it did something no other spacecraft had ever attempted — orbit and land on a comet.
