Euclid is a space mission selected by ESA as part of the Cosmic Vision 2015-2025 program, to be launched in 2022. Euclid will 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 FACe provides the CODEEN platform for continuous integration development in the Euclid’s ground segment framework.



LISA (Laser Interferometer Space Antenna) is the answer of the science community to the L3 large mission of ESA (European Space Agency): The Gravitational Universe. LISA aims at detecting low frequency garvitational waves from space, opening a completely new window into the heart of the most energetic processes in the Universe, with consequences fundamental to both physics and astronomy. LISA is an ESA-led project, with a strong participation of the European member states as well as NASA.

The FACe is involved in the discussion of data centre activities for LISA. The center hase been intensively used by the LISA Pathfinder mission, a prototype of the gravitational wave detector of the LISA project.



The Rubin Observatory / LSST (Large Synoptic Survey Telescope) is a project of a telescope in Chile, intended to realize from 2015 a sounding of the southern sky (20 000 square degrees) in 6 photometric bands (visible). The objective is to obtain constraints on the properties of the black energy complementary to those of BOSS.

The FACe is involved in the development of software of the command control pipeline of the LSST detector.



The SVOM (Space based multi-band astronomical Variable Objects Monitor) mission is a Sino-French project dedicated to the detection and study of gamma-ray bursts, which is scheduled to be launched at the end of 2021.

The FACe is involved in the development of software of the scientific pipelines.
