Far Above 2137

Far Above 2137 is a spaceflight sandbox focused on real orbital mechanics and deterministic simulation.

The game features a real Solar System in 1:1 scale, where distances, orbital periods, and velocities reflect actual values.

Every object in the universe — from planets to spacecraft — is driven by a pure state vector (position + velocity). There are no hidden forces, no gameplay shortcuts, and no approximations masking the underlying physics. What you see is the direct result of mathematics.

Orbits are not predefined paths — they are continuously derived from motion. Maneuvers are executed as instantaneous Δv impulses, and future trajectories are predicted using an event-driven solver that handles transfers, SOI transitions, and impacts.

Core principles

• Single source of truth — state vector, not orbit objects
• Deterministic physics — same input always produces the same result
• Patched conics model — clean and predictable multi-body behavior
• Impulse-based maneuvers — precise Δv execution in time
• Analytical + numerical propagation — Kepler + Velocity Verlet where needed

What you can do

• Plan and execute orbital maneuvers
• Perform transfers between celestial bodies
• Predict trajectories with multiple burns
• Observe real orbital behavior (apsides, inclination, SOI transitions)
• Experiment in a physically consistent sandbox

Current state

This is an early-stage project focused on building a solid simulation foundation.
Expect ongoing development of trajectory planning, maneuver tools, and gameplay systems.

Vision

The goal of Far Above 2137 is not just to simulate space —
but to create a system where every outcome is explainable, predictable, and mathematically correct.
