Euclid is a European Space Agency (ESA) mission designed to constrain the properties of dark
energy and gravity via weak gravitational lensing and galaxy clustering. It will carry out a wide
area imaging and spectroscopy survey in visible and near-infrared bands, covering approximately
15 000 deg2 of the extragalactic sky in six years. Euclid will be equipped with a 1.2 m diameter
Silicon Carbide (SiC) mirror telescope feeding two instruments built by the Euclid Consortium:
a high-quality panoramic visible imager and a near-infrared photometer and spectrograph. These
proceedings briefly describe the satellite and its instruments, which are optimised for pristine point
spread function and reduced stray light, producing very crisp images. Furthermore, we summarise
the survey strategy, the global scheduling, and the preparations for the satellite commissioning
and the Science Data Centers to produce scientific data.
