SpaceUp is an unconference that aims to be an informal meeting for the presentation and discussion of ideas, in which participants decide on the themes, program and structure of the event. All participants are encouraged to give a talk, start a discussion or moderate a session. This means that typical 'hallway talk' themes turn into constructive debate sessions. This was organized in partnership with the Space Generation Advisory Council Portugal (SGAC) and Pavilhão do Conhecimento – Centro Ciência Viva, Lisbon. SpaceUp Portugal 2019 had the highest number of participants of all editions, registering 120 people with very different backgrounds and nationalities, which allowed for discussions with very different points of view.
