About This Game

A realistic orbital mechanics sandbox set entirely within our solar system, governed strictly by real-world Newtonian physics and Einstein’s theories of relativity.

The simulation bypasses launch sequences and atmospheric escapes, placing your craft directly into an established Earth orbit. From this starting point, operation focuses entirely on orbital maneuvering, trajectory calculation, and navigation.

Core Mechanics & Navigation

Interplanetary transit relies entirely on directional thrust. You can not rely on the autopilot if you want to progress. Instead, you must manually rotate the craft to thrust at specific angles to alter your trajectory.

To travel between planets, you change your course by timing these manual burns to account for relative orbital velocities and gravitational influences. Reaching destinations like Mars or Jupiter requires precise rotation and execution of insertion burns and gravity assists, where your thrust angle dictates your final path.

Relativistic Physics & Visual Distortion

The engine actively simulates the physical effects of near-light-speed travel by dynamically calculating time dilation, length contraction, and relativistic aberration based on your velocity. Time dilation is tracked via synchronized readouts comparing your onboard ship clock with external coordinate time, mapping how seconds for you equal months or years in the solar system. Mechanically, the universe compresses along your vector of travel, while the engine calculates light aberration to shift and bunch your field of view forward.
