Rosetta:
Rosetta is on a 10-year mission to explore comet 67P/Churyumov-Gerasimenko. It will orbit Churyumov-Gerasimenko and make observations for about two years as the comet approaches the Sun.
Rosetta will also release a small lander packed with scientific instruments to make the first-ever landing on the surface of a comet.
