ESA’s Euclid mission to explore the hidden side of the Universe – dark energy and dark matter – reached an important milestone today that will see it head towards full construction. 

Selected in October 2011 alongside Solar Orbiter as one of the first two medium-class missions of the Cosmic Vision 2015–25 plan, Euclid received final approval from ESA’s Science Programme Committee to move into the full construction phase, leading to its launch in 2020.
