base on Oxidized Astrodynamics # Lox – Oxidized Astrodynamics ### A safe, ergonomic astrodynamics library for the modern space industry [](https://codecov.io/gh/lox-space/lox)   [](https://codspeed.io/lox-space/lox)  > **Note:** Lox is under active development and does not yet have a stable release. The API of all crates is subject to > significant change. ## Features Lox exposes a comprehensive astrodynamics API at varying levels of granularity. The high-level interface offered by `lox-space` is designed specifically for mission planning and analysis, while crates like `lox-time`, `lox-earth` and `lox-orbits` provide tools for advanced users. * A fully featured space mission simulator backend. * Python bindings for interactive use. * Tools for working with time in astronomical and terrestrial time scales. * Define orbits as Keplerian elements or state vectors in different coordinate frames. * Ephemeris, size and shape data for all major celestial bodies. * Ingest and interpolate Earth orientation parameters with ease. * Extensible – bring your own time scales, transformation algorithms, data sources and more. ## Crates ### lox-space The entrypoint to the Lox ecosystem, suitable for most use cases. Provides a high-level interface for mission planning and analysis. Also includes Lox's Python bindings. ### lox-time Tools for working with time in all commonly-used astronomical time scales based on a high-precision timestamp representation. Offers leap-second aware conversion from UTC to continuous time scales. ### lox-bodies Provides structs representing all major celestial bodies, conveniently categorized by a variety of traits exposing SPICE-derived data. ### lox-earth Essential algorithms for Earth-centric astrodynamics, including nutation-precession models, Earth rotation angle, CIP and CIO locations, and coordinate transformations. ### lox-ephem Parses ephemeris data from external sources such as SPICE kernels. ### lox-io Utilities for reading and writing data in various formats. ### lox-math A collection of mathematical utilities used across the Lox ecosystem. ## Used by... ### Ephemerista [][ephemerista] A next-generation, open-source space mission simulator [commissioned by the European Space Agency][artes]. ## Why "Lox"? > Liquid oxygen—abbreviated LOx, LOX or Lox in the aerospace, submarine and gas industries—is the liquid form of > molecular oxygen. It was used as the _oxidizer_ in the first liquid-fueled rocket invented in 1926 by Robert H. > Goddard, > an application which has continued to the present.
