The Rosetta orbiter

Scientific consortia from institutes across Europe and the United States provided the different instruments of the orbiter.  Rosetta’s industrial team involved more than 50 contractors from 14 European countries and the USA.  The prime spacecraft contractor was Astrium Germany. Major subcontractors were Astrium UK who built the spacecraft platform, Astrium France who supplied the spacecraft avionics and Alcatel Alenia Spazio for assembly, integration and verification.
