Espace Commun is a science communication and outreach initiative aimed at raising awareness of space sustainability among French-speaking Swiss citizens aged 15 to 35. Developed in partnership with Galactic Studios and funded by the Swiss National Science Foundation (SNSF) with a grant of CHF 200,000, the project combines digital engagement with in-person events to make the topic of sustainable space use accessible and relevant to a broader public. In 2026, the project will deliver a dedicated webpage, original content for social media platforms, a YouTube documentary, and two public events. This project reflects the Space Center’s commitment not only to advancing research, but to fostering an informed and engaged society around the future of space.
