GO JUP POS GLL: Galileo Spacecraft Trajectory Near Jupiter's Moons

Galileo spacecraft trajectory data in moon-centered coordinates for encounters with Amalthea, Io, Europa, Ganymede, and Callisto. Ephemeris data are provided every two seconds for approximately one hour about closest approach. The dataset is provided by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Modeling spacecraft orbital dynamics based on two-second ephemeris intervals
• Analyzing gravitational perturbations during close moon encounters based on moon-centered coordinates
• Visualizing flight paths for mission planning or education based on the provided trajectory data

Strengths

• Data provided at a high temporal resolution of every two seconds
• Covers encounters with five major Jovian moons: Amalthea, Io, Europa, Ganymede, and Callisto
• Originates from the authoritative source National Aeronautics and Space Administration

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
