In 2022 the European Space Agency will launch the Euclid satellite mission. Euclid is a medium class astronomy and astrophysics space mission that will undertake a galaxy redshift survey over the redshift range 0.9 < z < 1.8, while simultaneously performing an imaging survey in both visible and near infrared bands. The complete survey will provide hundreds of thousands of images and several tens of Petabytes of data. About 10 billion sources will be observed by Euclid out of which several tens of million galaxy redshifts will be measured and used to make galaxy clustering measurements. These observations will be used to help to understand Dark Energy, the physical mechanism causing the current acceleration in the expansion of the Universe. Percival is one of four science coordinators for the mission and co-leads the galaxy clustering science working group. Balogh, Hudson and Taylor are members of the experiment.
