Heliospice
Query spacecraft and planetary ephemeris data using SPICE kernels.
Setup
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 spacecraftlist_coordinate_frames — List available coordinate framesmanage_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?"
