Tenders Are Invited For S3-Cl-07 System-Integrated Space Materials Database For Dark Quiet Skies Compliant Designs - Expro+

Tenders are invited for s3-Cl-07 System-Integrated Space Materials Database for Dark Quiet Skies Compliant Designs - Expro+ The increasing deployment of satellites is raising concerns regarding their impact on ground- and space-based astronomical observations and the need to comply with emerging Dark and Quiet Skies (DQS) requirements. Reliable assessment of spacecraft visibility requires accurate knowledge of the optical properties of external spacecraft materials and their environmental degradation over time. However, existing data are limited, fragmented and often unsuitable for consistent spacecraft-level brightness analyses. This activity addresses this gap through the development of a system-integrated European database of optical properties for spacecraft materials with potential observational impacts, including solar arrays, multilayer insulation, thermo-optical coatings, antennas and external optical elements. The activity shall establish the required material datasets, perform dedicated measurement and characterisationcampaigns, and integrate the resulting data into an open-access database supporting DQS compliance assessments and brightness prediction tools. The project targets bringing the technology to TRL 7.Read more Tender Link : https://esastar-publication-ext.sso.esa.int/ESATenderActions/filter/open
