Universe Sandbox Legacy

Create and destroy on an unimaginable scale... with a space simulator that merges real-time gravity, climate, collision, and material interactions to reveal the beauty of our universe and the fragility of our planet. Includes VR support for HTC Vive, Oculus Rift+Touch, and Windows Mixed Reality.

Create, Collect, and Crash in Autocraft, a physics destruction sandbox. Create your own cars, rockets, tanks, planes, boats, and more.

The world's first science-based photorealistic interactive 3D planetarium that models the entire Universe, using procedural generation for uncharted areas.

A physics simulation software that simulates planetary motion and objects that obey Newton's laws,build slopes and connect geometries with sticks or springs and observe their trails.Observe the interaction and gravitational energy of planets.

ORBIT is a gravity simulator at the heart of a puzzle game. Launch planets with a flick of your hand, and try to get them into stable orbits around black holes. Create your own levels in the Sandbox, and publish your creations to the world for everyone to play.

Explore the cosmos as a comet, orbiting planets with a realistic gravity system and a backdrop of procedurally generated nebulae. Learn to use planetary gravity to your advantage, and relax in the ambience of space.

This is a simulation based upon real physics. Its specifically for use with 3D headsets such as the HTC Vive and Oculus quest. It gives you a 3D perspective of how gravity works and interacts on all the bodies in a solar system. You can experiment with creating your own solar system.

Join the James Webb Space Telescope in orbit beyond the Moon and explore the universe from its perspective. Planetary systems are born, galaxies form, and stars emerge from within colorful nebulas—all before your eyes.

The most scientifically accurate space warfare simulator ever made. Now with Steam Workshop!

Become a Space Mechanic! Get your hands dirty, explore the depths of space and repair broken machinery. Diagnose problems using diagrams and tools, perform repairs, manage your resources and watch the simulated machinery come alive. Or just gaze upon the beauty of the Solar System.

Sling shot explosive nuclear warheads into collision course with your planetary assassination targets. Using the gravitation of a planet against itself, while navigating your payload around asteroids, moons and even Black Holes for devastating effect!

A planetary physics game that challenges you to master the powers of the universe. Use orbital mechanics to maneuver the trajectories of moons, with the powers of changing gravity, creating black holes, forming wormholes, and even shooting lasers!

In Spaceflight Simulator, you will get to build your rockets, plan launches and flights, attempt landings, deploy payloads and explore new worlds.

This simulation software brings the solar system to your fingertips, allowing you to explore the orbits of planets and witness the fascinating effects of introducing new cosmic objects like asteroids, extra suns, or even a black hole.

Overview is a mind-changing experience about our position in the Universe. With a narrative and an interactive mode, it features realistic imagery and accurate data to leave you in awe and wonder at the vastness of the Cosmos.

Tiny Space Academy is a 2D space sim where you can grow your own space agency and explore our solar system with rockets you design! Learn basic orbital mechanics, run science experiments, and get your astronauts back to Earth safely.

Do you have what it takes to be an astronaut? Reentry is a realistic space flight simulator based on NASAs space programs; from the first American human spaceflight in Project Mercury, the rendezvous and EVAs of Project Gemini to the Moon landing in Project Apollo.

Satellite Command is a realistic, relaxing astrophysics simulator. Complete contracts with real data, launch and take control of ever more powerful Satellites, research advanced technology and build your Space Agency!

Get up-close and personal with Gravity. Chunky Orbits is a simulation of free-floating objects in space based on real life physics. Each object in the scene attracts each of the others in a cosmic tug-of-war that we call Gravity. Toss out a few boulders and contemplate the wonders of the Universe.
