For two days, the Cité des sciences et de l'industrie, located in the 19th arrondissement of Paris, opens its doors to the public for free to mark Décollez Jeunesse, a weekend of space-themed discoveries. This event is part of an international space summit and, more broadly, of the Summer of Astronomy hosted at the Cité des Sciences et de l'Industrie.
The concept of the event is to make space topics accessible to children and their families through a tailored program. Throughout the weekend, visitors can participate in activities, workshops, demonstrations, and chats with professionals from the space sector. The goal is to showcase careers, technologies, and major exploration missions in an educational, easy-to-understand way.
Organized in partnership with the CNES, the French space agency, and the ESA (European Space Agency), the event also tackles the big questions surrounding space exploration. Children can thus better understand the role of satellites, the mechanics of rockets, the living conditions of astronauts, or the research being conducted to explore the Moon, Mars, and other celestial bodies.
The event takes place at the Cité des sciences et de l'Industrie; admission is completely free for this exceptional weekend, inviting as many people as possible to participate in the various activities on offer. A great opportunity to learn everything about space as a family, from the youngest to the oldest!
