ESA's Euclid mission has passed its critical design review, marking the successful completion of a major phase in the progress of the project. The review verified that the overall mission architecture and detailed design of all its elements is complete, ensuring that it will be able to perform the unprecedented galaxy survey needed to tackle the mysteries of the dark Universe, and clearing the way to start assembling the whole spacecraft.
The review also assessed the feasibility of Euclid's survey with the designed flight hardware, which will image billions of galaxies across the cosmos at unprecedented sharpness and sensitivity during a nominal mission period of six years.
With the completion of this milestone that validated the whole project – from the spacecraft development to launch and operations, including also the observational methods and data analysis strategy – the assembly, integration and testing of the spacecraft flight model can begin. Immediately after launch, scheduled for June 2022, the ground segment will be ready to take over and start the operations to perform the groundbreaking sky survey.
