SpaceEngine is a Free Sandbox Space Exploration Game
Released: June 2010
Version: 0.9.7.3 (17 April 2015)
Developer : Vladimir Romanyuk
A free space simulation program that lets you explore the universe in three dimensions, from planet Earth to the most distant galaxies. Areas of the known universe are represented using actual astronomical data, while regions uncharted by astronomy are generated procedurally. Millions of galaxies, trillions of stars, countless planets – all available for exploration. You can land any planet, moon or asteroid and watch alien landscapes and celestial phenomena. You can even pilot starships and atmospheric shuttles. Using real astronomical catalogs and procedural generation, it creates a three-dimensional planetarium representing the entire universe. Users can travel through space in any direction or speed, and forwards or backwards in time. SpaceEngine is in beta status, and is currently freeware for Microsoft Windows. It uses pseudo-random numbers to procedurally create any kind of planetary system, nebula or galaxy.
The proclaimed goal of SpaceEngine is scientific realism, and to reproduce every type of known astronomical phenomenon. It uses star catalogs along with procedural generation to create a universe. The use of procedural generation allows for a much larger universe to explore than similar programs; billions of galaxies can be explored, each with billions of stars, planets and moons. The surfaces on terrestrial planets are generated using an algorithm based on fractal noise. Everything is based on the same seed, which produces the same simulated universe in every computer on which the program runs, making it possible to share locations between users.
