Rosetta is a robotic space probe built and launched by the European Space Agency. Along with Philae, its lander module, Rosetta is performing a detailed study of comet 67P/Churyumov–Gerasimenko (67P). It also performed a flyby of Mars and the asteroids 21 Lutetia and 2867 Šteins. On 12 November 2014 the mission performed the first successful landing on a comet. As of 2015, the mission continues to return data from both orbit and the comet's surface.
