Mission Context: In three years of operation, coronagraphic imaging with JWST has transformed the field of exoplanet research, providing spectacular images and spectra of exoplanets and dusty disks in the near and mid-infrared. These results have demonstrated the telescope's excellent optical quality and stability, enabling it to achieve detection limits down to 10^-5 in planet/star contrast.

The dissipation of vibratory energy in such structures plays a crucial role and taking it into account during the design process can be beneficial in lighting the weight of structures. Classical vibration mitigation device are typically made of elastomeric parts that are temperature-dependent and therefore less space-resilient than metallic technologies.

Furthermore, the recent launches of the PRISMA and ENMAP hyperspectral satellites [1] and the upcoming launches of satellites such as CHIME (ESA) and BIODIVERSITY (CNES) provide access to rich spectral information with high spatial resolution.
