Russell/Strange Jovian moon cycler family (family seed)

russell-strange-2009-jovian-multimoon-family · source: literature · validation: V0

Signature

Bodies: Io-Europa-Ganymede-Callisto
Primary: Jupiter
Sequence (canonical): Galilean-multi
Sense: n/a
Orbit class: Cycler
strict cycler (infinite returns)
Cycler class: multi-arc
Trajectory regime: ballistic
Maintenance ΔV band: unclassified
Model assumption: circular-coplanar
Idealised: planets on circles, coplanar ecliptic.
Period: — yr ( × synodic)
Family seed entry: Russell/Strange document hundreds of ballistic cycler geometries shuttling between pairs of Galilean moons (Ganymede-Io, Ganymede-Europa, Ganymede-Callisto, Europa-Ganymede, etc.) plus some multi-moon variants. No single period characterises the family; per-member periods are in the paper's tables which were not accessible at ingest (AIAA JGCD paywalled).
Priority date: 2007-01-29

Orbit view 2.5D ecliptic projection

spacecraft: idealized coplanar ellipse planets: J2000 osculating ellipse (Standish & Williams Table 1) orientation: coplanar-idealized (no Ω/ω published — in-plane ellipse)

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no sampled trajectory is published for this row — each leg is a separate ellipse with honest gaps where elements are unpublished (the 2D view above shows them).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).

Definition status

incomplete — core fields missing or known-unknowns tracked below

Known-unknowns (3)

Values we expect to exist but have not yet filled (distinct from "not applicable"). Tracked per upstream docs/spec.md §16.6.4.

orbit_elements.cr3bp.jacobi_constant [not-applicable]
Russell/Strange 2009 uses circular-coplanar patched-conic model. Jacobi constant is not conserved in this model. CR3BP identity for individual Jovian moon cyclers would use a per-pair (e.g., Jupiter-Ganymede) mass ratio, not catalogued here.

orbit_elements.cr3bp.period_nd [not-applicable]
Patched-conic model; non-dimensional CR3BP period not applicable.

Notes

Family seed entry covering the Jovian / Galilean half of Russell/Strange's catalogue. The paper "generalized previously applied enumerative cycler search and optimization techniques specifically for the Jovian and Saturnian moon systems... overall, hundreds of ideal model ballistic cycler geometries were found" (per search snippets of the JGCD abstract / ResearchGate landing page). For the Jovian system, double cyclers are documented for the Ganymede-Io, Ganymede-Europa, Ganymede-Callisto, and Europa-Ganymede pairings; multi-moon cyclers are also discussed. Family seed for the same reason as the heliocentric VEM-triple seed: full per-member ingestion requires the JGCD paper which was not accessible at ingest. As individual cyclers are tabulated, split them out as per-entry records keyed to this paper. M7 NOTE: Jovian-system finder hits cannot be auto-matched against this family seed; treat as "candidate-novel, flag for human review against Russell/Strange 2009" until member-level data is ingested. The Saturnian half of the same paper is captured as a sibling seed `russell-strange-2009-saturnian-multimoon-family` below.
