Europe’s advisor on space science and policy


The European Space Sciences Committee (ESSC) was established in 1974, as a means to establish an independent voice and leadership role for European space scientists in the international space arena.  The ESSC is an Expert Board hosted and administered by the European Science Foundation.

The European Space Sciences Committee provides impartial scientific advice to the European Space Agency, the European Commission, European national space agencies, and other decision-makers in the space domain.

They strive to be the reference body in Europe for independent expertise on matters of space science, acting as a representative voice of the European space science community and promoting international cooperation in the field.


ESSC Vision is to be widely established as an authentic and trusted voice of the European Space Sciences Community, recognized for their expertise in the field of space sciences, promoting fundamental, use-inspired, and applied space research, seeking to ensure maximum scientific benefits of Europe’s investments in the space domain (including the commercial sector), and increasing interest in and support for space sciences in the general public, the private sector, and the media.

ESSC Contribution to the public consultation on a Space Strategy for Europe


Last April, the European Commission opened a public consultation on a Space Strategy for Europe. The objective of this public consultation is to obtain stakeholder views on the policy priorities, challenges and opportunities that could shape a future Space Strategy for Europe. [See more]

ESSC Recommendations on the Horizon 2020 SPACE Work programme for 2018-2020

The following document highlights the recommendations and input of the ESSC to the EC consultation for the 2018-2020 work programme of Horizon 2020 (H2020) SPACE. There are three main areas for which ESSC provides inputs: transversal issues that touch all aspects of the H2020 SPACE calls, Space Science and Technology related issues and Earth Observation (Copernicus) related issues.
