The project main steps


The ROSETTA Mission of the European Space Agency (ESA) aims to study comet Churyumov Gerasimenko with which the probe has a rendez-vous in August 2014.

After a period during which a global mapping of the comet is realised by the orbiter, a closer observation phase should follow, including the sending of a module (Lander) down to the comet.

The launch, that took place the 2nd of March 2004 by an Ariane 5 launcher, will lead to a placing in the right orbit near the comet by August 2014 for an 18 month observation period.

France contributes twofold to this mission through:

  • technical participations to the Orbiter (through its contribution to the European Space Agency) and to the Lander (through a cooperation with the German Space Agency DLR),
  • scientific participations to the instruments on the Orbiter and on the Lander.
