Just a few weeks before Atlantis embarked on the final flight of the Space Shuttle program in 2011, a small Mexican company by the name of Squad quietly released Kerbal Space Program (KSP) onto an unsuspecting world. Until that point the company had only developed websites and multi-media installations. Kerbal wasn’t even an official company initiative, it started as a side project by one of their employees, Felipe Falanghe. The sandbox game allowed players to cobble together rockets from an inventory of modular components and attempt to put them into orbit around the planet Kerbin. It was immediately addictive.
There was no story to follow, or enemies to battle. The closest thing to a score counter was the altimeter that showed how far your craft was above the planet’s surface, and the only way to “win” was to put its little green occupant, the titular Kerbal, back on the ground in one piece. The game’s challenge came not from puzzles or scripted events, but from the game’s accurate (if slightly simplified) application of orbital mechanics and Newtonian dynamics. Building a rocket and getting it into orbit in KSP isn’t difficult because the developers baked some arbitrary limitations into their virtual world; the game is hard for the same reasons putting a rocket into orbit around the Earth is hard.
Over the years official updates added new components for players to build with and planets to explore, and an incredible array of community developed add-ons and modifications expanded the scope of the game even further. KSP would go on to be played by millions, and seeing a valuable opportunity to connect with future engineers, both NASA and the ESA helped develop expansions for the game that allowed players to recreate their real-world vehicles and missions.
But now after a decade of continuous development, with ports to multiple operating systems and game consoles, Squad is bringing this chapter of the KSP adventure to a close. To celebrate the game’s 10th anniversary on June 24th, they released “On Final Approach”, the game’s last official update. Attention will now be focused on the game’s ambitious sequel, which will expand the basic formula with the addition of interstellar travel and planetary colonies, currently slated for release in 2022.
Of course, this isn’t the end. Millions of “classic” KSP players will still be slinging their Kerbals into Hohmann transfer orbits for years to come, and the talented community of mod developers will undoubtedly help keep the game fresh with unofficial updates. But the end of official support is a major turning point, and it seems a perfect time to reminisce on the impact this revolutionary game has had on the engineering and space communities.
