Through his involvement in the Hipparcos and GAIA missions, Jordi had been a key contributor to the field of Astrometry in Spain and in Europe. He was also very active in many European Councils and Committees, including ESO council, ESA’s Astronomy Working Group or the European Space Sciences Committee.

Jordi was an active member of the ESSC panel on Astronomy and Fundamental Physics, and he contributed his broad experience and sharp reasoning to the discussion and deliberation of the Committee. He will be sorely missed.
