Siderust

Why it exists

Siderust provides validated astronomical computations for spacecraft navigation, observatory planning, and scientific research. Every algorithm is tested against JPL Horizons, IMCCE, and SOFA data.

Key Features

• VSOP87 & ELP2000 planetary/lunar ephemerides
• Type-safe coordinate systems (ICRS, Ecliptic, Topocentric)
• No unsafe blocks, no hidden allocations
• Validated against authoritative data

Getting Started

# Add to your Cargo.toml
[dependencies]
siderust = "0.1"

# Compute Mars position
use siderust::{
    bodies::Mars,
    astro::JulianDate,
};
use chrono::Utc;

let jd = JulianDate::from_utc(Utc::now());
let mars = Mars::vsop87e(jd);
println!("{}", mars.position);
