This mission operates in deep space — beyond the regime where SGP4 and CelesTrak TLEs apply. Real-time positioning needs NASA's JPL Horizons system, which isn't wired up yet. We track ISS, Tiangong, Hubble, and Chandra in low/high Earth orbit instead.
About this mission
The first mission to explore the Jupiter Trojan asteroids — primitive bodies trapped in Jupiter's orbit that are fossils of planet formation.
This mission has been operating for 1,655 days (4.5 years) — and it's still going.
Flyby missions use gravity assists to reach multiple destinations. Data is compressed into hours of intense observation at closest approach.
