Rosetta Mission

The Rosetta Mission is the third cornerstone mission in ESA's Horizon 2000 program. The purpose of the mission is to rendezvous with the comet 67P/Churyumov-Gerasimenko 1, gather information on the comet as the spacecraft orbits it, and to land a package of instruments on the surface of the comet. Scientific objectives of the mission are to study the origin of comets, and the relationship between cometary and interstellar material.

The Rosetta spacecraft launched in March 2004 from Kourou, French Guiana. On its way to the comet it will fly by two asteroids, (2867) Steins on 5 September 2008 and (21) Lutetia on 10 July 2010. Rosetta will rendezvous with 67P/C-G 1 and gather data on the comet for 18 months.

The scheduled end of mission date is 2014.

The Rosetta Mission web site is maintained by the European Space Agency (ESA).

The SBN in cooperation with ESA will archive Earth-based observations of comet 67P/Churyumov-Gerasimenko 1.
