B1. Port Harmonia Delta Quad Layout
Second century settlement layout around Port Harmonia. Shows new towns, satellite outposts, and main support way stations (names, bearings, distances, and the only column that really matters: why.)
Node | Type / Year | Bearing / distance | Lat-Lon coords. | Why it existed |
Port Harmonia | City Hub Year 1 | - | 35N 215E | On Amazonis / Arcadia Planitia flats, to west of Lycus Thrust (Acheron Fossae) |
Padport A | Padport | NE (Downwind) ~45+ km | 36N 216E | Early heavy EDL, minimal plume risk to people, short hauls. |
Padport B | Padport | SW ~100 km | 34N 214E | Seasonal redundancy; export spine anchor; denial move. |
Boreal | Industrial satellite | N ~100 km | 37N 214N | High-confidence water hub; pipeline once flow proved ≥80 t/day. Also useful geology and mine. |
Ridgeway | Industrial satellite | ESE ~70 km | 34N 217E | Aggregate + sulfur/geopolymer binders; civil mass saver. |
Acheron (Clayfields Mine) | Industrial satellite | ENE ~360 km | 35N 222E | Ceramics & membranes; life-support and fab up-chain, in Acheron Fossae |
Solaron (Oxide Solar Flats) | Industrial satellite | SW ~120 km | 33N 212E | Solar farms extension; Fe/Mg upgrading; local metallurgy; second resource azimuth. |
Amazonis Ville | Town (~1k) | SW ~260 km | 31N 210E | Med/fab hub; first travel node; latency reducer for SW axis. |
Lycus Ville | Town (~1k) | SE ~330 km | 31N 220E | Heavy workshops; sleeper/beam casting; WSW rail candidate. |
Arcadia | Science & | W ~420 km | 35N 209E | Advanced science on open Planitia. Doubles as a link way station for western resource trade arc. |
New Hawaii | Science & | W ~1,200 km | 39N 193E | Advanced science on Erbus Montes ridge island chain |
Erbus Ville | Town (~1k) | W ~1,650 km | 36N 187E | Acts as the western trade hub; completes the strategic coverage of Erbus Montes. |
New Milan | Science & | N ~1,450 km | 54N 213E | Advanced science in Polar region; strategic coverage of Vastita’s Borealis (Scandia Colles) |
The trunks that tied them together were named with the merciless cheer of engineers who know they’ll be saying the names for a century.
Spoke Borealis (Vastitas) ran North (NNW initially) to Boreal, then onto New Milan (Milankovic Crater). The two support stations on the way north from Port Harmonia to New Milan are Aldrin Station (44N 213E), Zurbrin Station (49N 213E).
Spoke Erbus (Montes) ran West to Arcadia, then on to Erbus Ville and New Hawaii. The three support stations on the way west from Port Harnomia to Erbus Ville and New Hawaii, are McGregor Station (39N 196E), BocaChica Station (35E 201E), Hawthorne Station (35N 194E).
Spoke Marte (Vallis) ran South West between the Agri and Solar zones to Solaron then Amazonis Ville.
Spoke Olympus (Mons) ran South East between the Solar and Industrial zones to the Ridgeway and then on out to Acheron and Lycus Ville.
Starport Spoke ran as a stub to the North East, and the wider Padport A zone.
From a coverage perspective, this table is useful:
Radius | Area (πr²) | ≈ Sectors covered | ≈ Provinces covered | Zands touched | Earth | USA |
300 km | ~283,000 km² | ~80 | ~8 | 2–3 | ~UK | ~Nevada |
400 km | ~503,000 km² | ~140 | ~14 | 3–5 | ~Spain | ~California |
500 km | ~785,000 km² | ~220 | ~22 | 4–6 | ~Turkey | ~Texas |
