3D view not available for multi-arc trajectories yet. The 3D system can now render a numerically-sampled polyline (n-body or multi-arc), but no sampled trajectory is published for this row — each leg is a separate ellipse with honest gaps where elements are unpublished (the 2D view above shows them). The button will appear here once a sampled path is exported for this trajectory; we never interpolate one from the catalogue's per-leg (a, e).

Notes

Lynam-Longuski 2011: single-period IEG triple cycler (E-perijove-I-G-apojove-E), Laplace period 7.05 d, total Delta-V ~11 m/s (patched-conic ephemeris/MALTO); ballistic version needs a -175 km Europa flyby. A 2nd independent source for the IEG triple-cycler class (Hernandez 2017 ref [7]). ingestion.
