Hours, directions, entrances and the best time to arrive
Where are the masterpieces inside Science and Industry Museum?
1/6
Space Mission
Attribute — Exhibit type: Immersive permanent space exhibition
This is the museum’s most ambitious recent gallery, built around the idea of putting you in an astronaut’s position rather than just showing space hardware in cases. It works well because the scale is bigger than most visitors expect, with mockups, simulations, and a five-part narrative that keeps adults engaged too. What people rush past is the sequence of technical and human challenges, which makes the later sections feel much smarter than a simple space display.
Where to find it: In the upper exhibition halls; it is one of the main destination exhibits and best tackled early in your visit.
L’Argonaute
Attribute — Artifact / Era: 1958 French submarine
Walking through Argonaute gives you a completely different type of museum experience: tight corridors, cramped control spaces, and an immediate sense of how little room submarine crews had. Many visitors focus only on the novelty of going inside a real submarine, but the onboard material about ocean exploration is also worth slowing down for. It is easy to miss because it needs a timed slot and sits outside the normal flow of the main galleries.
Where to find it: Docked beside the museum near La Géode, accessed on a reserved timed visit.
Planetarium
Attribute — Experience type: 360° dome show
The planetarium is one of the strongest ‘sit down and reset’ moments in the building, especially if you are already 2 hours into a big museum day. The projection is the obvious draw, but what many visitors miss is how useful it is for pacing: it gives kids and adults a real break without wasting museum time. The most popular morning shows fill first, so it is often missed by people who arrive without a reservation.
Where to find it: Inside the museum complex in the dedicated dome theater area; book your seat for a specific time.
Cité des Enfants
Attribute — Experience type: Timed children’s science play zone
This is not a side room for kids — it is a major attraction in its own right, with themed zones built for play, testing, movement, and cooperation. Families who treat it as a quick add-on usually shortchange themselves, because the full 90-minute session is what makes it work. The easy thing to miss is that parents need to plan their whole day around its fixed session times.
Where to find it: In the museum’s family area, accessed on a reserved timed session for the relevant age group.
Solar Impulse 1
Attribute — Artifact type: Full-size solar-powered airplane
Solar Impulse is one of those museum pieces people admire for 20 seconds and then move on from, which is a mistake. Seeing the aircraft at full scale makes the engineering idea land in a way that photos do not, especially once you notice how light and delicate the structure looks for something capable of sustained flight. Because it hangs overhead in the circulation space, plenty of visitors literally pass beneath it without pausing.
Where to find it: Suspended in the main exhibition hall as you move between major galleries.
Mediterranean aquarium
Attribute — Habitat type: Marine tanks
The aquarium is short, but it gives the visit a welcome change of rhythm after lots of screens, interactives, and large galleries. Rays, sharks, and reef fish are the headline draw, but the best detail is the ‘surface to depth’ progression, which makes the route feel more thoughtful than a standard tank corridor. People often miss it because it looks like a side branch rather than a major stop.
Where to find it: In the museum’s marine display area, reached off the main exhibition route.
