The Rosetta mission is a Planetary Cornerstone Mission in the European Space Agency’s program Horizon 2000. It had a rendezvous in August 2014 with comet 67P/Churyumov-Gerasimenko to study the chemical and physical properties of its nucleus and the development of its atmosphere as the comet approaches the Sun. Rosetta will follow the comet for about two years until its perihelion (August 2015) and beyond. Rosetta spacecraft was carrying an instrumented lander called Philae that has landed on the nucleus on November 12, 2014. On its way to the comet, Rosetta flew by asteroids 2867 Steins and 21 Lutetia.
