About Kerbal Space Program

In Kerbal Space Program, developed by Squad, you manage the ambitious space program of the Kerbals, a quirky alien race. The game challenges you to design, build, and launch spacecraft that operate based on realistic orbital and aerodynamic physics. Set in the expansive Kerbol solar system, you’ll explore planets and moons, construct bases and stations, and guide your Kerbal crew through perilous missions that balance creativity with engineering precision.

Realistic Spacecraft Assembly and Flight

Design spacecraft from a wide range of modular parts, each affecting flight performance under realistic physics. Your creations must endure the challenges of launch, orbit, and re-entry, with success depending on your understanding of aerodynamics and orbital mechanics. Execute advanced maneuvers, dock spacecraft, and assemble massive starships or stations in orbit.

The Kerbol Solar System and Surface Exploration

Venture across a fully realized star system featuring distinct planets and moons with detailed terrain. Use satellites to scan for biomes, uncover anomalies, and establish communication networks. Kerbals can perform “extra-vehicular” activities to gather data or construct bases on alien surfaces, extending your reach further into space.

Gameplay Modes and Program Management

Three modes offer varied challenges: Science Mode focuses on unlocking technology through experimentation; Career Mode tasks you with managing budgets, research, and development; Sandbox grants unrestricted creative freedom. Each mode allows you to hire, train, and deploy Kerbal astronauts to achieve your goals.

With extensive mod support and a thriving community, Kerbal Space Program provides endless opportunities for players to experiment, explore, and achieve in the pursuit of space exploration.
