Cité de l’espace is a science center dedicated to spaceflight and astronomy located on the Rangueil campus in Toulouse. It opened on June 27, 1997, and covers approximately three hectares. The center is operated by a non-profit organization under the patronage of the French National Centre for Space Studies (CNES) and the European Space Agency (ESA). The initial design was developed in the early 1990s in collaboration with research institutions and aerospace industry partners. Funding is provided by the Occitanie regional council, CNES, and sponsorships from aerospace companies.
The facility is divided into several thematic areas: In the rocketry and launch systems section, visitors can view a full-scale replica of the Ariane 5 launcher standing 53 meters tall. An authentic Soyuz spacecraft module and a reproduction of the Mir living module provide insights into life on an orbital station. The astronomy section features models of the Moon and planets accompanied by genuine rock samples. Interactive exhibits explain the fundamentals of physics such as gravity, vacuum conditions, and propulsion technology. A scientific garden hosts demonstrations on artificial gravity and simulated Martian environments.
The planetarium boasts a 25-meter-diameter dome and state-of-the-art projection systems for audiovisual presentations on constellations, galaxies, and cosmological phenomena. The on-site observatory is equipped with two high-power telescopes for direct observation of planets, nebulae, and star clusters. In addition, five screening rooms for documentaries, seminar and workshop spaces, and rotating temporary exhibitions are available.
The center regularly organizes professional symposia, lecture series, and scientific congresses, including the Toulouse Space Show, bringing together specialists from space agencies, universities, and industry. Its educational department develops curricular materials for schools, online modules, and teacher training programs. Collaborations exist with the University of Toulouse II and III as well as research laboratories in astrophysics and engineering.
Technical highlights include a demonstration model of the European Service Module for the Orion mission, live rocket engine test demonstrations, and a virtual reality simulator that realistically recreates the interior of a spacecraft. In the Earth observation section, satellite data from ESA’s Sentinel missions are processed and displayed via interactive maps. Other focal points include Mars exploration, human spaceflight, and space telescopes.
Architecturally, the site integrates flexible indoor and outdoor exhibition spaces. Barrier-free access with ramps and tactile guidance systems ensures full accessibility. An editorial team of science journalists, engineers, and astrophysicists regularly produces publications and traveling exhibitions. Cité de l’espace attracts about 350,000 visitors annually. Operation and financing are managed by the Cité de l’espace organization, the Occitanie region, CNES, and various industrial and scientific partners.
