Advanced Space Flight Lite vs Gravity Physics

Advanced Space Flight is a realistic space simulator for interplanetary and interstellar travel. It is the only space simulator available that takes into account relativistic effects during interstellar flight. Besides simulating space flight, this app can also be used as a planetarium, with all known planets shown in real scale with their accurate keplerian orbits. It can also be used as a star chart and exoplanet explorer, showing all solar systems with confirmed exoplanets within 50 light years from the Sun. This is the only app where you can get a sense of the true scale of the Universe, zooming out through thousands of galaxies and galaxy clusters until you see the entire observable universe in your screen. Locations with full access: - All inner planets in the Solar System and its moons: Mercury, Venus, Earth, Moon, Mars, Phobos, Deimos, Ceres - Nearby star systems: Proxima Centauri, Alpha Centauri, Sirius, Epsilon Eridani Locations with partial access: - All solar system planets plus 5 dwarf planets. - All confirmed exoplanetary solar systems within 50 light years. - Experience the full scale of the Universe: you can zoom out from a few meters to billions of light years, until you see the entire observable universe in your screen. Flight Modes: - Realistic Flight: Travel using optimised trajectories, calculated based on the orbital parameters of the origin and destination planets to minimise fuel usage. These are the kind of trajectories that would be used in a real space mission. - Free Flight: Take manual control of a spaceship in space, activating the engines as you see fit to achieve your goals. Spaceships: Advanced Space Flight features several spacecraft, but only one in available in this free version: - Space Shuttle (Chemical Rocket): Designed in 1968-1972 y NASA and North American Rockwell. It has been in service from 1981 to 2011, making it the most successful reusable spacecraft ever built. - Falcon Heavy (Chemical Rocket): Designed and manufactured by SpaceX, made its first flight in 2018. - Nuclear Ferry (Nuclear Thermal Rocket): Designed in 1964 by Ling-Temco-Vought Inc. - Lewis Ion Rocket (Ion Drive): Designed in a 1965 study by the Lewis Research Center. Artificial Satellites: Several human-made satellites are present in the app: - Sputnik 1 - Hubble Space Telecope - Internation Space Station - Kepler Space Observatory - Transiting Exoplanet Survey Satellite (TESS) - James Webb Space Telescope Join our discord community for discussions or suggestions about the app: https://discord.gg/guHq8gAjpu You can also contact me by email if you have any complaint or suggestion.

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.
