EuclidConsortiumObjectives Euclid space mission
• Understand the origin of the Universe’s accelerating
expansion
• Use weak gravitational lensing and galaxy clustering
probes to investigate the properties and the nature of
– dark energy,
– dark matter,
– gravity
Track their observational signatures on the
– geometry of the universe and
– cosmic history of structure formation

EuclidConsortiumStrength of the Euclid machine
Euclid Meeting Bologna, Sept. 7, 2011
A space mission:
• Deep NIR photometry (unfeasible from the ground)
• Superb and very table image quality (only feasible in space)
• Stable data: homogeneous data set (unfeasible from the
ground)
Stability: Systematics are small, understood and
controlled
Homogeneity : Selection function perfectly controlled
Deep NIR data for galaxies:
• Photo-z very well measured in the whole range
0.2<z<2.0 (tomography, intrinsic alignement)
• Unique Legacy value

EuclidConsortiumThe Euclid mission
Euclid Meeting Bologna, Sept. 7, 2011
• An M-class mission with constraints:
– Launcher : soyouz
– Maximum duration:7 years
• A Telescope
• 2 channels (Vis, NIR), 3 instruments (VIS, (NIS+NIP)=NISP)
• A mission: Euclid in L2, 2 surveys: Euclid Wide and Deep
• A (very important) ground segment
• An important external visible data set
• A strong core science and science team
• A collaboration between industry, ESA and the « Euclid
