There is another crate in Rust named Nyx [1] that sounds very similar - an astrodynamics library with a Python wrapper. Anyone knows how they compare?

[1] https://github.com/nyx-space/nyx

LOX is apparently MPL, so a bit easier to work with than Nyx' AGPL, but still at odd with the MIT/Apache2 combo that has become the norm in the Rust world.

There is also ANISE made by the same author: https://github.com/nyx-space/anise

Nyx is the OG Rust-based astrodynamics library and much more mature.

Lox started as a vehicle for myself to learn Rust and at that point I did not feel comfortable contributing to an established code base.

The only downside I see is agpl. Im not anti agpl, but truth is this would slow commercial adoption.
