Our Consortium
The Pollux consortium is composed of more than 150 scientists, and engineers from institutes in 11 European countries. At this step, national contributions are subject to formal approval of the respective agencies. The European consortium is led by France, under CNES leadership. It can be summarized by the organizational chart below. Our Project Office, includes a Project Manager (David Le Mignant, LAM) and an Instrument Scientist (Luca Fossati, IWF, Austria), in addition to the two Co-Is, Coralie Neiner (LIRA) and J.-C. Bouret (LAM). We are also in the process of recruiting a systems engineer for 2026, to complete the project office.
