Euclid is an ESA mission that will map the geometry of the Dark Universe. The mission will investigate the distance-redshift relationship and the evolution of cosmic structures by measuring shapes and redshifts of galaxies and clusters of galaxies out to redshifts ~2, or equivalently to a look-back time of 10 billion years. In this way, Euclid will cover the entire period over which Dark Energy played a significant role in accelerating the expansion of the Universe.
