ESA's Rosetta comet chaser is on its way to comet Churyumov-Gerasimenko. This immense journey will take it to the orbit of Jupiter where it will rendezvous with the comet and follow it back towards the Sun. It will also place a lander on the comet's surface to sample the composition. That is not all: Rosetta has been taking a look at some other asteroids along the way.
