A Walk to the Stars

A Walk to the Stars is exactly what it says: a walk… to the stars. From your very first rocket, work your way up to orbit, then build a base and spaceships to explore the real solar system.

Along the way, you learn and master the real laws of the universe — gravity, propulsion, orbital mechanics — one launch at a time.

This is not a heavy management game, nor a hardcore simulator. It is a walk: every shot is meant to be a painting, every launch a moment to take in.

A real solar system

The solar system in A Walk to the Stars is not a backdrop. The Sun, the planets and their moons move along their real orbits, computed from real astronomical data, at their true scale. The sky above the launch pad is the real sky.

Your rockets obey the same laws. Every launch is computed from your rocket — its mass, its thrust, its stages — and follows a real trajectory, from lift-off to orbit.

Built on real data

• The planets and their orbits — positions computed from NASA/JPL orbital data; the Moon follows JPL Horizons ephemerides (DE441).
• The night sky — NASA Goddard's Deep Star Maps 2020, built from the Hipparcos, Tycho-2 and Gaia star catalogues (ESA).
• The worlds themselves — the Sun, the planets, Earth, the Moon and Saturn's rings from Solar System Scope maps based on NASA data; Phobos and Deimos from the Viking missions.
• The International Space Station — NASA's own 3D model.
• Kourou and French Guiana — the land around the space center comes from Landsat satellite imagery, with coastlines, rivers and lakes from OpenStreetMap.

The road ahead

The journey starts with a program as real as it gets: the first rockets, the first orbits, then the exploration of the solar system. But if the adventure goes on… we'll probably need antimatter or nuclear propulsion to visit Proxima Centauri!
