Cosmic vision: the new ESA plan for space science

Abstract

Following the new financial constraints imposed recently on ESA's programme in space science, a full re-evaluation of the long term plan was carried out in the first half of 2002 by ESA and its scientific advisory bodies. The exercise has resulted in a new plan called "Cosmic Vision" which not only preserves the missions previously approved but also includes two further low cost missions. The new plan, stretching over the present decade, is based on the implementation of new management tools briefly mentioned in this paper. In describing the new plan, emphasis is placed on space astronomy missions by providing a brief description of each mission's goals and characteristics. The paper also addresses technology activities in preparation of future projects foreseen for an implementation in the next decade.
