COSPAR’s highest body is the Council. The Council is comprised of the Committee’s President, Representatives of Member National Scientific Institutions and International Scientific Unions, the Chairs of COSPAR Scientific Commissions, and the Chair of the Finance Committee. The Council meets at the Committee’s biennial Scientific Assembly. Between Assemblies it is the Bureau which runs COSPAR on a day-to-day basis (see the COSPAR Charter and By-Laws for further details).
