Kerbal Space Program

Kerbal Space Program is a 2015 space flight simulation video game developed by Mexican studio Squad for Linux, macOS, Windows, PlayStation 4, PlayStation 5, Xbox Series X/S and Xbox One. In the game, players direct the space program of a species of green humanoid aliens known as Kerbals. The game features a pseudorealistic orbital physics engine, allowing for various real-life orbital maneuvers such as Hohmann transfer orbits and orbital rendezvous. The first public version was released digitally on Squad's Kerbal Space Program storefront on 24 June 2011, and joined Steam's early access program on 20 March 2013. The game was released out of beta on 27 April 2015. Kerbal Space Program has support for user-created mods that add new features, such as interstellar travel, improved physics, new parts, and multiplayer. Popular mods have received support and inclusion in the game by Squad. The game has garnered commendation from spaceflight industry figures such as NASA, ESA, science communicator Scott Manley, former ULA CEO Tory Bruno, SpaceX CEO Elon Musk, and Rocket Lab CEO Peter Beck. In May 2017, Squad announced that the game had been purchased by video game company Take-Two Interactive, who would help support Squad in keeping the console versions up-to-date alongside the personal computer versions. An Enhanced Edition was released for Xbox One and PlayStation 4 in January 2018, and for PlayStation 5 and Xbox Series X/S in September 2021 by Private Division, a publishing subsidiary of Take-Two Interactive. Two expansions for the game have been released as downloadable content: Making History in March 2018 and Breaking Ground in May 2019. A sequel, Kerbal Space Program 2, was released in early access on 24 February 2023, although the developer has since shut down and no substantive updates have been released since June 2024.
