Ksp

Kerbal Space Program (KSP) is a space flight simulation video game developed by the studio Squad and released in 2011. Set in a fictional solar system, it tasks players with designing and piloting spacecraft using a modular parts system to explore, experiment, and survive as a crew of small green Kerbals. The game emphasizes realistic physics, including orbital mechanics, aerodynamics, and propulsion, and centers on a design-build-fly loop.

Gameplay centers on three modes: Sandbox, Career, and Science. In Sandbox, players have unlimited resources to freely construct and test vehicles. Career mode introduces contracts, funds, reputation, and a technology tree that unlocks more advanced parts as players perform science experiments. Science mode focuses on collecting data to unlock parts and progress without career constraints. Players build rockets and spaceplanes, manage stages, plan transfers between bodies, achieve orbits, dock with stations or other vessels, land on moons or planets, and return safely to Kerbin.

Content and features include a diverse set of celestial bodies, such as Kerbin, the Mun, and Minmus, with mission variety ranging from simple suborbital hops to complex interplanetary journeys. The game supports extensive modding, expanding parts, realism, and mission types. Official expansions such as Making History and Breaking Ground add mission-building tools and robotics, respectively, broadening gameplay.

Platform availability and reception: KSP has been released for Windows, macOS, and Linux, with ports to consoles. It is praised for its approachable yet challenging physics, its open-ended design, and its educational potential, fostering a large community of builders, pilots, and modders. A sequel, Kerbal Space Program 2, has been released in early access and continued development.
