In plain words
Kerbal Space Program is a space exploration simulation where players assemble spacecraft from individual parts and launch them based on realistic physics and aerodynamics. Users guide their Kerbal crew to orbit, land on moons and planets, and construct bases and stations throughout the Kerbul solar system. The game emphasizes problem-solving through trial and error, with community forums and mods extending gameplay possibilities. It appeals to space enthusiasts and simulation fans seeking a challenging sandbox experience.

This idea originally started as an educational simulation but as i've gone more down the rabbit hole the more i've wanted to make it realistic. The problem is that I've never had a formal orbital mechanics class or anything like that so I don't know what I'm missing, what I currently have implemented is: Variable gravity Variable Atmospheric drag (US Standard Atmosphere 1976) Multi-stage rockets Closed-loop guidance /…
