A Space Odyssey: ESA Rosetta Mission on Twitter

Information about the mission:

Rosetta is the first mission in history to rendezvous with a comet, escort it as it orbits the Sun, and deploy a lander to its surface. The robotic space probe, built and launched by ESA, the European Space Agency, already performs a detailed study of comet 67P/Churyumov-Gerasimenko. The spacecraft arrived at the comet on 6 August 2014 following a 10-year journey through the Solar System. Since then the Rosetta spacecraft orbits the comet and gathers data to characterise the environment and the comet nucleus. On November 12, 2014, Rosetta's Lander Philae will attempt to land on the surface. Philae carries a suite of instruments for imaging and sampling the comet nucleus.

The mission is controlled from ESA’s European Space Operations Centre (ESOC), in Darmstadt, Germany. It is an ESA mission with contributions from its Member States and NASA. Rosetta’s Philae Lander is provided by a consortium led by DLR and MPS (Germany), CNES (France) and ASI (Italy).Scientists claim that this mission is more complex than landing on the moon.
