Euclid: The space mission and the spectroscopic sample

Euclid is a European Space Agency (ESA) mission, designed to investigate the nature of dark energy and dark matter. The satellite launch took place in July 2023, instrument commissioning and performance verification were completed successfully and data taking started in mid-February 2024. The survey will continue for the next six years covering one-third of the entire sky. It will map the matter distribution by measuring positions, shapes, and colors for billions of galaxies, and also redshift for a subset of tens of millions of those with unprecedented accuracy. This proceeding will present an overview of the mission, with particular attention to the spectroscopic analysis and its systematics.
