# Veenie — Full Reference > Composable browser-native aerospace simulation suite. Open-source Venus physics engine, interactive 3D simulators, 1,600+ airfoil database, and aerospace engineering tools. Built by Ivan Karaman · ivan@veenie.space · https://veenie.space --- ## Mission Venus at 50km altitude is roughly 0°C and 1 atm — habitable conditions in a planet with 120–1500× Earth's deuterium concentration and CO₂/H₂SO₄ suitable for methalox ISRU at scale. The long-term goal is industrializing the Venusian atmosphere for propellant production and deep-space infrastructure. Operationalizing this requires autonomous pilots capable of weeks-long atmospheric station-keeping. Veenie's approach: build the most physically accurate Venus simulator that runs in a browser, collect human demonstration flights, and train an LLM pilot on that data. Every human flight is AI-compatible training data by design — the human UI and AI API dispatch identical commands (VENT_GAS, DROP_BALLAST, INFLATE) through the same headless physics engine. Research presented at LPSC 2026: https://www.hou.usra.edu/meetings/lpsc2026/pdf/2024.pdf --- ## Physics Engine Open-source, headless TypeScript. Runs in Web Workers with zero GC pressure on the main thread. **Repository:** https://github.com/hackiku/veenie **Integrator:** 4th-order Runge-Kutta, dt=0.1s, Z-up Cartesian coordinate system. Pre-allocated workspace vectors — zero heap allocations in the hot loop. **Validation against VEGA 1 (1985):** - Mean float altitude: Veenie 54.4km vs observed 53.6km — 1.4% deviation - Diurnal oscillation period: ~60h vs observed ~58h ✓ - Night float stability: 99+ hours ✓ **Environment modules:** - VIRA atmosphere (0–100km density/temperature/pressure, log-linear interpolated) - Beer-Lambert cloud opacity (48–70km) - Solar ephemeris from Venus orbital elements (177.3° axial tilt) - Zonal superrotation + meridional Hadley cell wind vectors - Atmospheric gravity wave perturbations - Upwelling/downwelling IR flux profiles **Aerostat systems:** - Envelope buoyancy and lift gas management - Helium permeation (Fick's Law + Arrhenius thermal coefficient, calibrated to metallized Kapton P≈10⁻¹⁸) - CO₂ solid oxide electrolysis → CO + O₂ (ISRU) - Solar power budget and battery management - ResourceBus: strict power and gas allocation per tick **Architecture:** 3-phase loop — gather (solar → power bus) → process (ISRU draws power, aerostat vents/leaks) → kinematics (RK4 with per-subsystem force summation). --- ## Simulators ### Venus Balloon — https://veenie.space/fly Flyable Venus atmospheric mission.
