“Next stop: space!” A weekend for exploring the universe

Explore space through exhibitions

At the event, discover the great space adventure thanks to:

• Models of CNES and ESA satellites, rovers and space probes, with experts on site to explain the details of these extraordinary missions.
• Virtual reality experiences: explore the International Space Station and behind the scenes of Ariane 6 at the Guiana Space Centre.
• Demos and interactive experiences to learn about current and future space technologies.
• A space dedicated to the EU's space programmes, Galileo, Copernicus, IRIS² and Space Situational Awareness (SSA): from navigation and Earth observation to climate, telecommunications and security, discover how space transforms our daily lives.

Space, live from the Forum

All day long, a series of scientists, engineers and experts from the CNES and ESA will share their knowledge and answer questions from the public, on topics such as exploration, planetary defence, Earth observation, innovations and major space challenges. Professional astronauts will also make a special appearance to share their passion for space.

Young people take the stage

On Saturday at 2 pm, young people involved in CNES and ESA educational programmes will speak about their passion for space and learning journeys, during a special two-hour event dedicated to careers, dreams and challenges in the world of space.

Experiment, build, take off!

For young people between the ages of 4 and 15, SpatioLab space workshops will be offered all day, organized by the CNES and led by scientific educators from the organization Planète Sciences.

• Argominots: discover sea turtles and how they are protected through satellite monitoring. (ages 4-6)
• Build your own orbital station: embark on an adventure where you're in command of designing your own orbital space station. (ages 8-15)
• Pilot your own Mars rover: design and pilot machines on planet Mars. (ages 8-15)

Plus:

• Escape game - ISS mission: step into the shoes of a space team and act fast to locate and repair a mysterious air leak that's threatening the safety of the International Space Station. (ages 12 and older)

A great opportunity to learn while having fun...and maybe even inspire future careers in space!
