Abstract: Euclid is the second Medium Class mission of the Cosmic Vision programme of the European Space Agency. The launch date of this cosmology mission is foreseen in 2020 and the mission has a nominal duration of 6 years. Euclid carries a 1.2 meter telescope, which will survey 15,000 deg2 of extra-galactic sky in the visual and near-infrared. The mission is optimized to measure two complementary cosmological probes: weak lensing and galaxy clustering. The sub-arcsec resolution images of Euclid are of extremely high quality to meet the stringent weak-lensing requirements. Euclid will carry out near-infrared slitless spectroscopy of the same survey area, to investigate galaxy clustering. The data rate of Euclid is unprecedented for an ESA astronomy mission. The cosmology objectives of the mission can only be met with a large data processing effort, including data from ground based surveys. We present an overview of the science objectives and the resulting mission implementation and sky survey. We describe the Euclid science ground segment: the data flow and processing as well as its organisation.
