The objective of the DART mission, successfully achieved, was to deviate the Dimorphos asteroid trajectory in a measurable way, to demonstrate the kinetic impactor technique for planetary defense purpose. </p><p style="text-align:justify;">In the frame of the AIDA (Asteroid Impact & Deflection Assessment) collaboration between the European Space Agency and NASA, after DART comes Hera, to be launched on late 2024 towards the binary asteroid system for post-impact assessment. Hera will onboard two nano satellites, one of which is italian and named “Milani" in honor of the scientist and astronomer Andrea Milani, passed away in 2018. Milani nano satellite is developed by a consortium led by Tyvak International (italian Prime Contractor) and will mainly execute hyperspectral measurements and dust detection. </p><p style="text-align:justify;">CIRA is part of the Milani consortium and is collaborating through the “Laboratorio di Qualifica Spaziale", where in 2022 the qualification of the “Ianus" cold gas propulsion system – jointly developed by Tyvak International and T4I – was successfully completed. Tests did foresee mechanical shock, vibration and thermal vacuum. Next step will be the environmental campaign of the Milani nano satellite, before its integration in the Hera mothercraft. <br></p><p style="text-align:justify;"><em><br></em></p><p style="text-align:justify;"><a href="https://www.tyvak.eu/">Tyvak International srl</a> <span lang="EN-US"><em>is the European subsidiary of Terran Orbital and leading aerospace
