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.","ecosrequired":false,"establishment":"ESOC","firstPublicationDate":"2026-07-22T14:18:54","id":192131,"idEra":25464,"initiatingService":"OPS-S","ipmeasure":"N/A","isArchived":false,"isCancelled":false,"isReissued":false,"isToBeReissued":false,"issueQuarter":"000","lastUpdateTime":"2026-09-21T12:01:13","lastUpdateUser":"spancott","openDate":"2026-09-21T12:01:06","priceRange":null,"programmeReference":"S2P P3 Clean Space","tanumber":"1-13642","title":"S3-CL-07 SYSTEM-INTEGRATED SPACE MATERIALS DATABASE FOR DARK QUIET SKIES COMPLIANT DESIGNS - EXPRO+","directorate":"Directorate of Operations","countries":[{"id":1},{"id":6},{"id":9},{"id":10},{"id":15},{"id":23},{"id":24},{"id":62},{"id":67},{"id":5}],"products":[{"id":259},{"id":320},{"id":356},{"id":405}],"technologies":[{"id":414}],"status":{"id":2},"tenderType":{"id":5},"isFavourite":false,"eraVersion":1,"stageNumber":null,"isNew":false,"isUpdated":false,"declarationOfCompliances":["All the required declarations of compliance have been addressed and included in our proposal's Cover Letter"],"keyAcceptanceFactors":["The Tenderer confirms that the tender Cover Letter and the Detailed Proposal contain a binding price;","The Tenderer confirms, on its behalf and on behalf of its Subcontractor(s), to be compliant with the “Non Benefits Requirements” (see section 1.8 of the EXPRO/TC);","The Tenderer confirms, on its behalf and on behalf of its Subcontractor(s), to accept the conditions established for “Non commitment by the Agency in competitive procurements” (see section 1.7 of the EXPRO/TC);","The Tenderer confirms, on its behalf and on behalf of its Subcontractor(s), to fulfil the requirements concerning “Free Competition” (see paragraph 10 of the Cover Letter of the Proposal Template);","The Tenderer confirms, on its behalf and on behalf of its Subcontractor(s), to satisfy the “Eligibility Requirements” (see section 1.1 of the EXPRO/TC);","The Tenderer confirms that the tender is compliant with the budgetary limit applicable to the ITT.","The Tenderer confirms that the tender Cover Letter and the Detailed Proposal contain a price type compliant with the one requested in the ITT;"],"evaluationCriterias":[{"criterion":"Background and experience (related to the particular field concerned) of the company(ies) and key personnel, including adequacy of proposed facilities.
