ISOS Pilot Mission Detailed Design – HOST component
17.500.000€
Description
The main goal of this opportunity is to develop capabilities for acting in space by demonstrating a pilot mission focused on In-Space Operations and Services (ISOS) by 2030. The mission seeks to lay the groundwork for a future service infrastructure that will support the European in-space ecosystem. It aims to boost the new in-space economy, improve in-orbit technology demonstration, and strengthen Europe's independence in space technologies. Key focus areas include building a sustainable, flexible, and economically viable space infrastructure, advancing circular economy approaches in space, and meeting both governmental and commercial needs through innovative system designs. This opportunity is open to organizations based in EU Member States, Norway, and Iceland.
