🚀 Build, Fly, Dream
Kerbal Space Program offers a deeply rewarding sandbox experience built around authentic orbital mechanics. You are given complete control over your space agency's development:
-
Complete Vehicle Assembly: Build rockets, spaceplanes, rovers, and probes from a massive catalog of parts. Every thruster, fuel tank, and aerodynamic wing you attach directly affects how your spacecraft handles in flight.
-
Realistic Orbital Physics: The game’s physics engine simulates real-world orbital mechanics. You’ll need to learn how to manage thrust, execute gravity turns, plan maneuver nodes, and perform complex orbital rendezvous.
-
Explore an Entire Solar System: Launch beyond your home planet, Kerbin, and discover unique moons, massive gas giants, and distant planets. Each celestial body features its own gravity, terrain, and atmospheric conditions.
-
Three Ways to Play:
-
Sandbox Mode: Unleash your creativity with unlimited parts, funds, and zero restrictions.
-
Science Mode: Perform space experiments to unlock new technology and expand your Kerbals' knowledge of the universe.
-
Career Mode: Oversee every aspect of the space program. Manage your budget, upgrade facilities, hire astronauts, and take on lucrative contracts to fund your expeditions.
-
Endless Modding Potential: KSP boasts one of the most dedicated modding communities in gaming. Install hundreds of community-made mods to add new parts, enhance graphics, or introduce realistic life-support systems.
