On 24 March, over a dozen engineers gathered at Euclid industrial prime contractor, Thales Alenia Space in Turin, to carefully attach the two main parts of the Euclid spacecraft: the payload and supporting service modules. This task required such extreme precision that it took a whole day, followed by two days of connecting electronic equipment and testing that Euclid’s instruments still work.

The Euclid mission will be launched in 2023 to explore the dark Universe. Thales Alenia Space is ESA’s prime contractor for the construction of the satellite and its service module. The payload module, including the telescope, was developed by Airbus Defence and Space.
