Real gravity. No autopilot. Pilot a spacecraft through 8 hand-crafted orbital mechanics missions Pilot a spacecraft through 8 hand-crafted orbital mechanics missions - all powered by a live N-body gravity simulation using Velocity Verlet integration. Every burn matters. Fuel is finite. The universe does not care about your intentions. --------------- 8 MISSIONS --------------- Training - Learn the controls: fly through 5 gate checkpoints around Earth. Lunar Orbit - Launch from Earth and achieve a stable orbit around the Moon. Rendezvous - Dock with a moving space station by matching its velocity precisely. Jupiter Grand Tour - Orbit Io, Europa, and Ganymede - three separately stable orbits in one mission. Planetary Defense - Intercept an inbound asteroid and thrust it off its collision course with Earth. Perihelion - Burn deep into the inner solar system and fly through the Sun's gate at closest approach. Nebulon 5 - Thread through five massive plasma nebulas (instant death on contact) and dock with the gold asteroid at the centre. Three Body Problem - Navigate three mutually orbiting suns evolving in real-time chaotic N-body motion. --------------- FEATURES --------------- * Live N-body gravity simulation - Velocity Verlet integration * Live trajectory prediction - 500-step lookahead updates in real time * Time warp - 1x, 2x, 4x, 10x, 50x with sub-stepped physics * Three flyable spacecraft - Dart, Vanguard, and Atlas * Per-ship personal best times for every mission * Procedural planetary rendering - atmospheric glow, limb darkening, solar corona * Plasma nebula renderer - organic blob shapes with Hubble-style textures * No ads. No in-app purchases. No internet connection required. ## Rankings - #1,348,612 — Overall ## Similar extensions and apps - [Lunar Perfect Drop](https://chrome-stats.com/d/id6771775600) - [Orbital Simulator: Explorer](https://chrome-stats.com/d/id6511195732) — 5.00 / 5 - [Orbital Gravity: Space Arcade](https://chrome-stats.com/d/id6759335900) - [Gravity Courier: Orbit Puzzle](https://chrome-stats.com/d/id6777101289) - [Orbital Odyssey - Space Voyage](https://chrome-stats.com/d/id6761362448) - [Orbit Path: Space Traveller](https://chrome-stats.com/d/id6767645013) - [Orbit Weaver: Gravity Lab](https://chrome-stats.com/d/id6764565461) - [Space Simulator](https://chrome-stats.com/d/id516849108) — 4.70 / 5 - [Orbit Mission](https://chrome-stats.com/d/id6775084037) — 5.00 / 5 - [Gravity Physics](https://chrome-stats.com/d/id6785758114) - [Universe: Orbit Swing](https://chrome-stats.com/d/id6775132414) - [Orbitrix](https://chrome-stats.com/d/id6748710763) — 5.00 / 5 --- Source: [Chrome-Stats](https://chrome-stats.com/d/id6762437099)
