aldrin-4-3-2-establishment · source: literature · validation: V0

Signature

Bodies: E-M
Sequence (canonical): E-M
Sense: outbound
Period: 4.270 yr (2 × E-M synodic)
Establishment timeline over a 2-synodic period using V-infinity leveraging.
Priority date: 2012-08-13

V∞ at encounters

E (#1): 5.51 km/s
Rogers 2012 Table 4 reports V_inf,flyby ranging 5.51-6.55 km/s depending on the specific variant; 5.51 applies to the 4:3(2) architecture.
M (#2): — (not published)
Specific V_inf at Mars not isolated in the Rogers abstract/accessible tables for this sub-variant.

Orbit elements (heliocentric)

Semi-major axis a: — AU
Eccentricity e: —
Perihelion: — AU
Aphelion: — AU
Inclination: —°

Values are specific to the establishment epoch and shift slightly from the idealized 1.60 AU Aldrin baseline. Left null per spec §16.2 until full STOUR logs can be verified.

Legs

E → M: (TOF not published)
Rogers 2012 notes ToF ranges 161-172 d in the analytic ephemeris model; exact value for the 4:3(2) variant is not explicitly paired in the aggregated text.

Notes

Captures the practical reality of flying an Aldrin cycler in a real ephemeris. The 4:3 notation indicates the spacecraft completes 4 orbits while Earth completes 3. The variant uses V-infinity leveraging manoeuvres to push the idealized circular-coplanar trajectory into the eccentric real solar system.
