A Family Activity During Hot Weather

When temperatures rise, it can be difficult to find an activity that keeps children entertained for an entire day. At the Euro Space Center, the adventure continues whatever the weather.

The Astronaut Day experience offers more than 6 hours of discovery through 11 immersive and interactive activities inspired by the daily life of astronauts. Here, you do not just watch — you take part.

Take a seat in the Space Rotor to experience the effects of a space launch, test your abilities in the Space Hub, discover what lunar and Martian gravity feels like, explore the Mars Village, or admire the stars in the Planetarium.

Each activity helps visitors better understand the challenges faced by astronauts while enjoying a genuine space adventure. And because most experiences take place indoors in air-conditioned spaces, the exploration continues even when outdoor temperatures soar.
