« An incredible experience (we did both)! Well done on your work, and thank you for letting us experience this. »
What you’re about to experience
You’re going to witness the birth of stars.
You’re about to set foot on Mars.
You’ll come back with different questions.
The journey
A glimpse of a few passages – the journey has plenty more in store.
01
One planet amongst billions
The Earth is part of the Solar System, orbiting our star, the Sun. Our Sun is one of hundreds of billions of stars in the Milky Way.
02
March: The Red Planet
Mars is the fourth planet in the Solar System, neighbouring Earth. Its surface is teeming with intriguing geological formations such as giant volcanoes and immense canyons.
03
Travelling to other worlds
Exoplanets located in the habitable zone could harbour life. But they are tens or hundreds of light-years away.
