January 7, 2020 – Arianespace and the European Space Agency (ESA) announced the signature of a launch services contract for the Euclid satellite – with the mission’s timeframe for liftoff starting in mid-2022 from the Guiana Space Center, Europe’s Spaceport in French Guiana. Euclid is a medium-class astronomy and astrophysics space mission in ESA’s Cosmic Vision 2015-2025 scientific program to investigate the history of the expansion of our Universe over the past 10 billion years, looking into the current acceleration of cosmic expansion fuelled by a mysterious component referred to as dark energy, and the growth of cosmic structures driven by the presence of dark matter. To this aim, Euclid will survey galaxies at a variety of distances from Earth in visible and near infrared wavelengths, over an area of the sky covering more than 35 percent of the celestial sphere. The Euclid mission will utilize either a Soyuz or an Ariane 62 launch vehicle from the Guiana Space Center, Europe’s Spaceport in French Guiana (South America), with a launch timeframe starting in mid-2022.
