About
The mod introduces various rocket engines designed for different flight requirements, resource-rich asteroids, orbital mechanics for celestial bodies, a dedicated space dimension, and the Moon. It also features the "Sputnik" probe, which enables both visual and functional programming (of course in Lua) for precise rocket control, as well as persistent loading for physics contraptions from Sable.
Dependencies
❗For the mod to work properly, Create Aeronautics is required (who would have thought)!
