# RAstro
rastro is a modern space dynamics library for research and engineering
applications. It is designed to be high performance, easy to learn, and
fast to code, and ready for flight.

The key features are:

- **Intuitive**: API designed to be easily composable, making it easy to 
  solve complex problems correctly by building on core functionality.
- **Easy to Learn**: Designed to be easy to use and learn. Less time reading 
  papers, more time building.
- **Fast to code**: Rastro provides a Python 3.6+ wrapper that is
  auto-generated from the core rust libraries. Making it easy to use without
  compromising performance.
- **Fast to run**: Very high performance, on par with C++ libraries, thanks
  to core library being written in Rust.

RAstro gets its name from the combination of Rust and astrodynamics (Rust + 
astro = RAstro). Space dynamics is an expansive field that covers multiple 
domains of mathematics, astrodynamics, attitude dynamics, and systems 
engineering. While the underlying concepts have been studied and known since 
Kepler wrote down his three laws, there are few modern software 
libraries that make these concepts easily accessible. Space dynamics 
software generally runs into the following pitfalls:

1. It is usually expensive, commercially licensed software making it 
   inaccessible for students, hobby projects, or new endeavours.
2. They are heritage libraries making integration with modern tools challenging
3. They are heritage APIs, while extremely well tested, also have an extremely 
   steep learning curve. Additionally, the closed-source nature makes it 
   difficult, if not impossible, to understand the true algorithmic 
   implementation. This can make root-causing issues and learning from the 
   software prohibitive. 

Due to these challenges, students, researchers, and engineers frequently end up 
reimplementing common astrodynamics functions with an unfortunately frequent 
regularity. While  reimplementation of common code can be a good learning 
mechanisms, in most cases it is both error-prone and costs time better spent 
on other endeavours. This project seeks to address this challenge by 
providing an easy-to-use, well-tested library, built in Rust for 
performance with bindings to Python for ease of use.

This project builds on experience from past projects in building space 
dynamics software:
- [brahe](https://github.com/duncaneddy/brahe) A pure-python astrodynamics 
  library
- [SatelliteDynamics.jl](https://github.com/sisl/SatelliteDynamics.jl) A 
  Julia astrodynamics library

## Documentation

You can find the package documentation [here](https://duncaneddy.github.io/rastro).
This documentation is meant to provide a human-friendly walkthrough of the
software and package. RAstro is currently in the early stages of development so
the documentation will likely not be complete. Sections marked **[WIP]**
will have some software functionality implemented but not be considered
documented.

The most complete API reference guide will always be the Rust crate API 
reference, found [TODO]. This is always up-to-date with the latest release 
since it is autogenerated at build time during the release process.

## Software Usage and License

The RAstro package is licensed and distributed under an [MIT License](https://github.com/duncaneddy/rastro/blob/main/LICENSE) to
encourage adoption and to make it easy to integrate with other tools.

The only thing asked is that if you do use the package in your work, or
appreciate the project, either send a message or star the project. Knowing
that the project is being actively used is a large motivator for continued
development.

### Support and Acknowledgement

RAstro is currently being developed primarily for my own enjoyment and
because I find having these tools helpful in professional work. I plan to
continue developing it for the time being regardless of greater adoption,
time permitting.

That being said, it's incredibly encouraging and useful to know if the
software is being adopted or found useful in wider practice. If you're
using RAstro for school, research, or a commercial endeavour, I'd
love to know about it! Tweet me [@duncaneddy](https://twitter.com/DuncanEddy) or
email me at duncan.eddy (at) gmail.com.

I'd love to hear your feedback or thoughts!
