Scientific paper

The present interest in small bodies of the solar system has placed a high priority on missions to asteroids and comets. The results of recent flybys of small bodies have confirmed the scientific value and technical feasibility of such missions. ESA has identified four mission scenarios as potential backup candidates for the joint ESA/NASA Rosetta-CNR mission as the future of ESA/NASA cooperation is uncertain. A possible Ariane 5 direct escape launch for the year 2002 offers a wide range of possible targets for each mission scenario, some of which may use gravity assists. Mission requirements, constraints and operations are discussed. A reasonable launch mass has been determined for each scenario and the corresponding spacecraft design is discussed in terms of mass, complexity and technical risks. These scenarios offer a wide range of opportunities for small body exploration with varying costs and levels of complexity.
