At the end of August 2021, the final vibration test was carried out with the Helga and Zohar flight models (FM) at the DLR Institute of Space Systems in Bremen. This test simulated the acceleration to which the two radiation measurement mannequins will be exposed during the launch of the Artemis I mission. The final test was successful. They are now ready for installation in the Orion spacecraft, which will take them to the Moon and back.
