nyx
Nyx is a high fidelity, fast, reliable and validated astrodynamics toolkit library written in Rust and available in Python.
The target audience is mission designers, astrodynamics engineers/hobbyists, and GNC engineers. The rationale for using Rust is to allow for very fast computations, guaranteed thread safety, and portability to all platforms supported by Rust.
