Welcome to a realistic orbital mechanics sandbox set entirely within our solar system. In this simulator, space is a dynamic fabric governed by the laws of real-world physics. From basic Newtonian orbits to the complexities of Einstein’s theories of relativity, every trajectory is bound by the actual equations that dictate the universe.

You begin your journey already in orbit around Earth. There are no launch sequences or atmospheric escapes to manage. Instead, you immediately take control of your craft in the vacuum of space, pushing your navigation skills to the absolute edge as you master the mechanics of relativity.

Not a Standard Space Game

Navigating between celestial bodies requires more than just pointing your ship at a planet and pressing forward. Unlike typical space games where travel is immediate or linear, moving through this solar system demands a true understanding of orbital mechanics and general relativity. To move from Earth to targets like Jupiter or Mars, you must carefully plot multi-stage trajectories that account for orbital speeds and gravitational pulls. Executing precise slingshot maneuvers and calculating exact insertion burns are the only ways to reach your destination. One decimal point out of place will sling your craft into the deep void.

True Relativistic Physics

Velocity changes your entire reality. As your vessel approaches a fraction of the speed of light while moving through the solar system, you will witness relativistic effects firsthand.

• Time Dilation: Watch planetary orbits accelerate around you while your onboard clock slows down. A few minutes of high-velocity travel for you could mean months or years passing for the rest of the solar system.

• Length Contraction: See the physical geometry of space compress along your line of travel, requiring precise calculations to avoid missing your orbital targets.
