Orbit One

Orbit One is a space exploration game about designing rockets, planning launches and plotting orbital maneuvers. You develop your skills from humble beginnings, starting with simple rockets around Earth and unlocking more powerful vehicles and scientific instruments as you demonstrate your orbital maneuvering abilities.

Plan your missions

You manage orders for multiple spacecraft and plan launches, landings and maneuvers, which are automated. Planning tools help coordinate maneuvers across several craft and plot efficient, timely courses. You can also use the vehicle designer to choose engines and specialized modules, adjust tank sizes and staging, and tune performance to meet mission requirements.

Master orbital mechanics

The game simulates N-body physics, offering a more accurate model than standard two-body approximations. You work with unstable orbits and Lagrange points as you plan increasingly distant explorations.

Explore the solar system

Missions take you to the Moon, Mars and beyond, including the moons of Jupiter, Saturn and Uranus, as well as Neptune’s icy satellite Triton. Completing missions unlocks larger, more powerful and more sophisticated rocket parts. You can take on real-life scenarios or enter sandbox mode to explore at your own pace.
