Trajectory record

Time-dependent navigation trajectory

Source states place the model at the selected time. Reconstructed flight, estimates, predictions and historical mission plans are identified by interval; gaps remain visible.

Coverage: December 25, 2021 to September 27, 2026

Source records and sampling assumptions are retained with the repository data. Model attitude and surface appearance are illustrative.

  • James Webb Space Telescope: Physically reconstructed based on publicly available data. JPL Horizons reconstructed as-flown state solution, checked by held-out midpoint interpolation (maximum accepted position residual 0.1 km); 106 subsecond transition gaps remain open. Absolute navigation uncertainty is not reported by the source. · December 25, 2021 to September 27, 2026
