A SpaceUp is an "unconference" focused on space, both the aerospace industry and the associated science. The first french edition of a SpaceUp, SpaceUp Paris, was held at the CNES Launchers Directorate on May 24, and ESA Headquarters on May 25-26, 2013. The second one was held at Cité de l’espace in Toulouse in Sept. 2014. The next edition will take place at Espace Air Passion, in Angers, on May 20 & 21, 2023. At SpaceUp, Engineers, astronauts, entrepreneurs, scientists, developers, students, graphists, journalists & dreamers discussed together of the future of space exploration. 21 nationalities were represented, and one-third of the participants were women! Participants decided the topics, schedule, and structure of the event. Indeed, everyone who attends SpaceUp is encouraged to give a talk, moderate a panel, or start a discussion. Sessions are proposed and scheduled on the day they’re given, which means the usual “hallway conversations” may turn into full-fledged topics.
