Use satellites to scan terrain and find biomes and other anomalies.

Dock spacecraft together to construct space stations, massive starships, and surface bases on new planets.Send your Kerbal crew outside their ships for “extra-vehicular” activities.

Discover a whole star system with unique moons and planets, exploring detailed terrain at a vast scale.Manage your Kerbal crewmembers, including hiring, training, and sending them into space to become heroes.Take full control over your ship’s setup to execute complex flight maneuvers.Build spaceships, rockets, and vehicles using any imaginable combination of parts, each with their own function that will affect the way your spacecraft behaves.

Try out the many mods created by the Kerbal Space Program community! In Sandbox, you are free to build any spacecraft you can think of, with all parts and technology in the game. In Career Mode, oversee every aspect of the space program, including construction, strategy, funding, upgrades, and more. In Science Mode, perform space experiments to unlock new technology and advance the knowledge of Kerbalkind. Kerbal Space Program features three gameplay modes. Launch your Kerbal crew into orbit and beyond (while keeping them alive) to explore moons and planets in the Kerbol solar system, constructing bases and space stations to expand the reach of your expedition. You have access to an array of parts to assemble fully-functional spacecraft that flies (or doesn’t) based on realistic aerodynamic and orbital physics. In Kerbal Space Program, take charge of the space program for the alien race known as the Kerbals.
