Où vas-tu comme ça ?

Où vas-tu comme ça ?　 is a 3D experience for exploring the Solar System and spaceflight data by moving freely through it.
Follow the paths of Voyager 1, Voyager 2, and other spacecraft.
Cross planetary orbits.
Travel far away and turn around to see the Solar System from a new perspective.
The data stays the same.
Your perspective changes.
The Sun that dominates the view nearby becomes smaller as you travel away, until it is almost lost in the distance. A spacecraft trajectory that looks like a simple line from one direction reveals a very different shape when you move around it.
And space is mostly empty.
In Où vas-tu comme ça ? you can travel through that emptiness too. The farther you go, the less there is to see.
Spacecraft trajectories and celestial positions shown in Où vas-tu comme ça ? are based on publicly available astronomical and spaceflight data. LaChaise is not intended to be a precision astronomical simulator or navigation tool.
Instead of simply reading the data, step inside it.
360°. Any direction you like.
Travel through the Solar System from your own point of view.
