Industrial involvement in the Rosetta mission

Industrial involvement in the Rosetta mission

The Rosetta spacecraft was built by an industrial team led by prime contractor Astrium GmbH, Friedrichshafen, Germany, and involving more than 50 contractors from 14 European countries and the USA. Major subcontractors were Astrium Ltd. who built the spacecraft platform, Astrium France who supplied the spacecraft avionics and Alenia Spazio, Turin, Italy, for assembly, integration and verification. Canada participated in the construction of ESA's first 35 m-diameter Deep Space Antenna in Australia, which was built for Rosetta. Scientific consortia from institutes across Europe and the United States provided the 11 experiments for the orbiter.

The lander, Philae, was provided by a European consortium headed by the German Aerospace Research Institute (DLR). Other members of the consortium are ESA, CNES, ASI, and institutes from Austria, Finland, France, Hungary, Ireland, Italy, and the United Kingdom.

This page lists the industrial involvement in the Rosetta Orbiter and the mission's ground segment. 

The industrial involvement in the Philae Lander is detailed on a separate dedicated page.
