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.

Strap in, Commander. 500 worlds are waiting, and every one of them wants to break your lander. PROJECT VOYAGER: NEW FRONTIER is a retro arcade landing game built on the real universe. Start on the Moon. Work your way out through Mars, Venus, the moons of Jupiter and Saturn, Pluto and Eris at the edge of the solar system. Then leave home behind for 479 real exoplanets discovered by astronomers, light-years from Earth. LAND IT. DON’T BOUNCE IT. Tilt, burn and feather your engine onto the pad. Every world has its own gravity, and some have atmosphere and wind. Each world has 10 landings, and every one is tougher than the last. Past Venus, the galaxy fights back: smaller pads, deep narrow craters, jagged rock spires and cliff-top mesas. Then the asteroids show up. THE DAILY HIGH SCORE BOARD Every run counts. Make today’s worldwide top 10 and enter your three initials, just like the arcade. The board resets every midnight, and the top 3 earn a mission patch to keep forever. PLANT THE FLAG Conquer a world and your astronaut plants the American flag on it, in whatever space suit you’re wearing. Collect a mission patch for every world you take. THE SHOP Spend the credits you earn on 38 ships and 32 space suits. Fly every Apollo lunar module from Eagle to Challenger, and finally land Apollo 13’s Aquarius. Drive Curiosity and Perseverance down by sky crane, or take the Space Shuttle. Or skip the history and land a UFO, a disco ball, a hot air balloon, a taco, a covered wagon or an astronaut on horseback. Then suit up in Mercury Silver, polka dots, tie-dye, a glow skeleton or your city’s colors. BUILD YOUR FLEET Unlock 10 more ships as you push deeper into space: fuel savers, heavy-duty landers, precision probes, auto-levelers, landing radar and an asteroid deflector. Upgrade your Fuel Tanks, Landing Gear and Warp Drive with the credits you earn. FEATURES 500 worlds, 5,000 landings Real solar system bodies and real exoplanets Daily worldwide arcade leaderboard with initials Daily podium patches and mission patches A Shop with 38 ships and 32 space suits, all bought with credits you earn by playing 10 unlockable ships that each fly differently Craters, spires, asteroid fields, wind and thick atmospheres Flight Log with your full career stats Pure 80s arcade style: pixel type, glowing vector lines and chiptune sound Simple two-thumb controls No account needed.
