Paper Abstract

The Scientific Ground Segment (SGS) of the ESA M2 Euclid mission, foreseen to be launched in the fourth quarter of 2019, is composed of the Science Operations Center (SOC) operated by ESA and a number of Science Data Centers (SDCs) in charge of data processing, provided by a Consortium of 14 European countries. Many individuals, scientists and engineers, are and will be involved in the SGS development and operations. The distributed nature of the data processing and of the collaborative software development, the data volume of the overall data set, and the needed accuracy of the results are the main challenges expected in the design and implementation of the Euclid SGS. In particular, the huge volume of data (not only Euclid data but also ground based data) to be processed in the SDCs will require a distributed storage to avoid data migration across SDCs. The leading principles driving the development of the SGS are expected to be the simplicity of system design, a component-based software engineering, virtualization, and a data-centric approach to the system architecture where quality control, a common data model and the persistence of the data model objects play a crucial role. ESA/SOC and the Euclid Consortium have developed, and are committed to maintain, a tight collaboration in order to design and develop a single, cost-efficient and truly integrated SGS.
