What is Helper Systems: kOS?

kOS is a community-developed mod for the Kerbal Space Program game that adds a programmable computer system to spacecraft. It allows players to write scripts in a custom scripting language to automate and control spacecraft functions, enabling complex maneuvers and mission automation within the game environment.

From my experience with kOS, I found it excels at providing a powerful yet accessible way to automate spacecraft control within Kerbal Space Program. Writing scripts to handle complex maneuvers adds a rewarding layer of depth to gameplay and serves as a practical introduction to programming concepts. However, the learning curve can be steep for those unfamiliar with scripting, and mod compatibility requires attention with game updates. Overall, if you enjoy space simulation and want to enhance your missions with automation, kOS is a robust and free tool that delivers significant value.
