The European Academies Science Advisory Council, EASAC see the EASAC home page, is formed by the academies of the European Union nations, Norway and Switzerland. It aims at providing science in the European decision making process.

EASAC decided some time ago to contribute to the European space policy by launching a study aimed at providing some guidance on the question of human presence in space. This is a very costly issue that is often debated in the public and within the space professional community. I had the pleasure to chair the group of experts that prepared this report  issued in September 2014. You find here a summary in French and English and the full report to download. A summary paper in French published in the magazine "Pour la science" November 2014 is  published heer in the associated post in French.
