The powerful influence of the Sun and the nature of the mysterious ‘dark energy’ motivate ESA’s next two science missions.

Solar Orbiter and Euclid were selected by ESA’s Science Programme Committee for implementation, with launches planned for 2017 and 2019.

These two missions are medium-class missions and are the first in ESA’s Cosmic Vision 2015-2025 Plan.
