The International Rosetta Mission was approved in November 1993 by ESA's Science Programme Committee as the Planetary Cornerstone Mission in ESA's long-term programme in space science, Horizon 2000. The mission's main goal is a rendezvous with Comet 46P/Wirtanen, but it will also study two asteroids during close flyby en route to the comet. Rosetta will study the nucleus of Comet Wirtanen and its environment in great detail for almost 2 years, the near-nucleus phase starting at a heliocentric distance of about 3.25 AU, from onset of activity through to perihelion, close to 1 AU. Launch is planned for January 2003 on an Ariane-5 from Kourou, French Guiana. [Image Date: 1998/04] [98.06.003-001]
