Industrial involvement in the Gaia spacecraft

Industrial involvement in the Gaia spacecraft

Gaia was designed and built by Astrium (now Airbus Defence and Space), with a core team composed of Astrium France, Germany and UK. The industrial team included 50 companies from 15 European states, along with firms from the US. Some 80 contracts were placed with European companies and three with those in the US. The spacecraft was launched by Arianespace. Between 2,500 and 3,000 people in all are involved in the mission.
