Descripción
For the Visible Light Imager and Magnetograph (VIM) a high-resolution filtergraph is under design. The system takes advantage of a lithium niobate (LiNbO3) crystal which can be used as a scanning filter using high voltage for tuning. We have undertaken first studies to qualify a lithium niobate wafer of 70 mm aperture size for deployment and use in space. We show the results of the mechanical mounting and vibration and thermal cycling tests as well as stability tests under fast voltage tuning in vacuum. Although these tests have all been very successful, further environmental testing is necessary to fully space-qualify the filter for the Solar Orbiter mission.

    Primitive asteroids in the Main Belt possess one of the most pristine inventories of materials in the Solar System. Main Belt primitive asteroids are particularly interesting due to clear evidence of phyllosilicates, i.e., silicates that have encountered liquid water and undergone chemical alteration. Since asteroids are thought to be likely

    NEOMIR: project statut of ESA's space-based infrared mission for NEO detection and early warning
    To warn about potential asteroid or comet impacts, we must first observe and discover these objects through dedicated NEO surveys. Most current and planned surveys are ground-based and use visible light, but they face limitations like weather dependency, limited sky visibility, difficulty detecting at low galactic latitudes, and inability to
