Real-world ephemeris data and J2000 orbital state vectors. Every maneuver is mathematically grounded in actual astrodynamics — no fake gravity shortcuts.
64-bit double precision across the entire scene. Experience millimeter-perfect docking tolerances without floating-point drift breaking the sim.
Full six-degrees-of-freedom translation and rotation. Master the V-Bar approach where the orbital paradox holds: speeding up means slowing down.
All navigation displayed in the Local Vertical Local Horizontal frame — the same coordinate system used by actual spacecraft crews.
Hohmann transfers, phasing burns, perturbation forces (J2 oblateness, atmospheric drag). The simulation that KSP only dreamed about.
Historical ISS docking profiles, Gemini rendezvous, Apollo LM approaches — each recreated from mission archives and flight rules.
Astrodynamics deep-dive, SPICE toolkit evaluation, UE5 LWC feasibility tests.
6DoF thruster model, physics integration, LVLH HUD overlay. Basic V-bar approach playable.
Live kernel loading, state vector interpolation, real ISS orbital elements.
Full mission suite, tutorials, scenario editor, community leaderboards.
No spam. No filler. Just updates when something real ships — new build drops, Steam launch date, devlog posts.
