Several team members wish Euclid a happy first launch anniversary in their own language. ESA’s Euclid satellite launched on 1 July 2023 on a SpaceX Falcon 9, and now resides in an orbit around the Sun-Earth Lagrange point L2. During its mission, Euclid will observe billions of galaxies out to ten billion light-years over one third of the sky to study dark matter and dark energy.
