CASTRA is the leading Bulgarian non-government structure supporting the development of the Bulgarian space sector, including the establishment of the related national policies and strategies. CASTRA experts are involved in different public and private expert groups related to space at national and EU levels.

As a strong independent professional organization CASTRA actively supports Bulgarian  government  towards the  development of a sustainable environment for industrial, R&D, educational and public outreach activities in Bulgaria related to space.

The successful integration and membership of Bulgaria in the EU implies active participation in the definition of the EU space policy and in the work of the EU executive bodies related to space exploration and related tasks at both EU and national levels.
