From 2010, the CM was improved with the goal of space missions. Today, the CM reaches the status of a flight model mechanism already delivered for the EUCLID space mission (launch expected by 2021). It is also derived into a cost optimized actuator so called ICAR that will be manufactured in approximately 20 units for the ELT-METIS ground based instrument.
This paper gives an overview of the CM design and its different configurations. The paper will describe more in details the different tests that were carried out on the Euclid-CM, covering performances, vibrations, electromagnetism, thermal cycles, exported torques and life-time tests.
