Store description excerpt
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.
