19th ESPI Autumn Conference: Europe as a Space Power – Directionality & Priorities of Strategic Action
2025-10-28 - 2025-10-29 | Vienna, Austria
For the first time in Autumn Conference history, the Conference will convene at the Vienna Rathaus.
Space is an arena of power politics and so, increasingly, a tool of international power projection.​ The place of Europe in space as a strong actor and trusted global partner is having growing pains. ​In spite of its landmark achievements and solid foundations, Europe today lacks the political will — at the true scale of its economic power and talent — to assert itself as a full space power.​
​The 19th edition of the ESPI Autumn Conference will address the pathways for Europe to become a full-fledged space power and reinforce its role as a partner to the world, bringing together high-level European and international stakeholders.
