Create Cosmonautics transforms childhood dreams of spaceflight into a logical extension of your Create engineering projects. Instead of simply building static rockets, you design and fuel actual engines with specific thrust profiles, taking your contraptions from the overworld into a dedicated space dimension and onto the surface of the Moon. This is for builders who have already mastered Create's kinetic systems and want a reason to apply that knowledge beyond the atmosphere—mining resource-rich asteroids and solving the puzzle of interplanetary logistics without leaving the mechanical philosophy behind.

The mod adds real constraints like delta-v budgets, transfer windows, and persistent physics from Sable, so a hastily built rocket will break apart or miss its target. The "Sputnik" probe lets you script flight control in Lua, blending visual programming with functional logic to execute precise burns, staging, and landings. Every celestial body follows orbital mechanics; you are not simply teleported—you pilot your craft through vacuum.

Multiple rocket engines tuned for atmospheric ascent, vacuum travel, and landing, each with distinct fuel consumption and thrust curves.
Orbital mechanics that require planning launch timing, intercepts, and deceleration burns rather than instant travel.
Resource-rich asteroids in a persistent space dimension, rewarding mining expeditions with rare materials.
The Moon as a tangible destination with unique terrain and resource distribution.
Lua-programmable Sputnik probe for automated maneuvering, telemetry, and staging, usable through a visual interface.

You must have Create Aeronautics installed—this mod builds directly on its physics and contraption handling. Your rockets are not decorative; they are physical machines that experience stress, heat, and collision. Expect to iterate designs and fail often before reaching orbit.
