heliospice

# Heliospice Query spacecraft and planetary ephemeris data using SPICE kernels. ## Setup ```bash pip install heliospice ``` ## What You Can Query **Spacecraft (36+)**: Parker Solar Probe, Solar Orbiter, Juno, Cassini, Voyager 1/2, Mars 2020, MRO, New Horizons, Europa Clipper, Psyche, BepiColombo, JUICE, Lucy, Galileo, Dawn, MESSENGER, and more... **Planets**: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto **Moons**: Moon, Titan, Europa, Ganymede, Io, Phobos, Deimos, and many more **Other**: Sun, asteroids, comets, Solar System Barycenter ## Tools - `get_spacecraft_ephemeris` — Position at single time or timeseries (with optional velocity) - `compute_distance` — Distance between two bodies over time range (min/max/mean, closest approach) - `transform_coordinates` — Transform vectors between coordinate frames (RTN, J2000, ECLIPJ2000, etc.) - `list_spice_missions` — List all supported spacecraft - `list_coordinate_frames` — List available coordinate frames - `manage_kernels` — Check status, download, load, or purge kernel cache ## Examples - "Where is Parker Solar Probe right now?" - "What's Earth's distance from the Sun?" - "Show me Juno's trajectory for January 2024" - "When did Mars get closest to Jupiter in 2024?" - "Convert this RTN vector to J2000 frame" - "What's the current Moon position?"
