Gravity Physics vs Project Voyager

Gravity is a real-time N-body physics simulation of our solar system — fly a spacecraft through accurately modeled orbits, gravity wells, and atmospheres, all rendered in a clean top-down view of the ecliptic plane. Every body uses real physical data: mass, radius, orbital elements, and atmospheric density where applicable. Gravity between all 26 bodies — Sun, planets, major moons, and dwarf planets — is computed live using velocity Verlet integration, so orbits, perturbations, and gravity assists emerge naturally from physics, not scripted paths. FEATURES • Pilot your own spacecraft — configure engine count, thrust, and mass, then launch from Earth • True N-body gravity — every body pulls on every other body and on your ship, in real time • Realistic atmospheric drag and heating — feel the difference between skimming Earth's atmosphere and diving into Venus or Saturn • Time controls — speed up months of orbital motion or slow down to precision-dock in real time • Trajectory prediction — see where your current heading will take you before you commit • Flight trail — trace your path across millions of kilometers • Extended telemetry — track speed, altitude, gravity, thrust-to-weight ratio, dynamic pressure, hull temperature, time dilation, and more Whether you want to attempt a Hohmann transfer to Mars, slingshot past Jupiter, or just watch the Moon orbit Earth in fast-forward, Gravity gives you a physically accurate sandbox to explore the mechanics of our solar system.

Navigate the real universe in Project Voyager: New Frontier! Command an advanced deep-space landing module as you pilot your way through true astronomical destinations across our solar system and beyond. From historical lunar touchdowns on Apollo 11's Mare Tranquillitatis to atmospheric descents through Venus and the distant exoplanets of TRAPPIST-1, every flight tests your thrust timing, fuel management, and orbital precision. EXPLORE REAL ASTRONOMICAL MISSIONS • Mission 1: Earth-Moon System — Touch down on Luna, Oceanus Procellarum, and historical Apollo landing sites. • Mission 2: Inner Planets — Battle heavy atmospheric drag on Venus, brave Mars's Olympus Mons, and touch down on Phobos. • Mission 3: Outer Giants & Kuiper Belt — Navigate the icy crusts of Europa, Enceladus, Titan, and Pluto. • Missions 4 & 5: Interstellar Horizons — Journey light-years out to Alpha Centauri and the alien worlds of TRAPPIST-1. • More Missions to Come! DEEP SHIP TECH & UPGRADES Earn Voyager Points on every successful touchdown to upgrade your spacecraft: • Warp Drive: Boost score multipliers for maximum points. • Fuel Capacity: Expand fuel reserves for tough, high-gravity maneuvers. • Thrust Power: Upgrade engine output to counter punishing atmospheric pull. KEY FEATURES • Realistic vector physics, thrust vectors, and variable gravity. • Dynamic atmospheric drag and landing pad tolerance checks. • Full campaign map tracking active planetary flight paths. • Emergency Abort system for tactical deep-space maneuvers. • Retro vector arcade visual style paired with clean modern UI controls. Do you have what it takes to guide Voyager to humanity's next frontier? Strap in, monitor your thrusters, and achieve touchdown!
