ESA’S I NDUSTRI AL POLI CY About 85% of ESA’s budget is spent on contracts with European industry. ESA’s industrial policy : 1. ensures that Member States get a fair return on their investment; 2 . im proves com petitiveness of European industry; 3. maintains and develops space technology; 4. exploits the advantages of free competitive bidding, except where incompatible with objectives of the industrial policy.
