Video: Euclid completes thermal vacuum testing

At the Thales Alenia Space test facility in Cannes, France, the massive door of the thermal vacuum chamber was opened after a month of rigorous testing of ESA's Euclid mission to explore the dark universe.

In Cannes, the fully integrated spacecraft was subjected to the conditions of space and its subsystems were fully tested for the first time. With the Euclid space telescope, scientists hope to learn more about dark matter and dark energy which could make up more than 95% of our universe.
