ESA’s Euclid mission to explore the hidden side of the Universe – dark energy and dark matter – reached an important milestone in June 2012 that will see it head towards full construction. Read more about the final approval from ESA’s Science Programme Committee to move into the full construction phase, leading to its launch in 2021.

Euclid is ESA's M2 satellite mission of the Cosmic Vision program in which APC, together with the FACe, is contributing to data processing. Read the CNRS/IN2P3 communiqué and the ESA press release.

Euclid is an ESA mission to map the geometry of the dark Universe. The mission will investigate the distance-redshift relationship and the evolution of cosmic structures. It achieves this by measuring shapes, luminosities at different wavelenghts and redshifts of galaxies and clusters of galaxies out to redshifts ~2, or equivalently to a look-back time of 10 billion years. It will therefore cover the entire period over which dark energy played a significant role in accelerating the expansion.

The APC is heavily involved in the preparation of this mission, which is supposed to be launched in the 2021 time frame. The APC is leading the efforts of one of the workpackages concerning the data analysis of Euclid data within the French community. This involves the comparison with observations from other dark energy projects, such as LSST, and the development of specific software and of data handling techniques. The FACe will be used for data processing tasks and connection to the super-computing facilities and data storage at the CC-IN2P3 in Lyon.
