| Abstract: |
Euclid is the second medium-sized mission of the ESA Cosmic Vision
2015-2025 Plan, aimed at understanding the nature of dark energy and
dark matter by accurately measuring the accelerated expansion of the
Universe, with a planned launch in Q1 of 2020. The success of the
mission heavily relies on careful design and implementation of its
ground segment facilities. The Science Operations Centre (SOC) operated
by ESA and a number of Science Data Centres (SDCs) provided by a
Consortium of 12 European countries plus the USA, in charge of data
processing, are the elements of the Euclid Scientific Ground Segment
(SGS). 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. 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 will require a distributed storage to avoid data migration
across SDCs. |
