(relative to city + other wedges)

Starport Hub & ATC

45° (NE)

12 o’clock

~3 km

Gateway between city and starport: close enough for rapid response, but offset downwind of hab; sits on the head of the NE logistics corridor feeding pads, customs, and industry without crossing hab streets.

Customs/Security & Quarantine

15–75° (NE)

11–1 o’clock

~4-5 km

Straddles the main outbound/inbound flow to the starport so all traffic can be screened before entering the city; uses the same NE corridor airflow so exhaust/dust move away from hab; avoids crossing power/water trunks to S/SW.

Operational Starport (primary pads, ATC)

15–75° (NE)

11–1 o’clock

~6–10 km+

Downwind of the city under prevailing westerlies; far enough to cut dust/acoustic loads; aligned with approach/climb corridors that never overfly hab; adjacent to heavy-industry arc for short GSE/prop runs.

Donor Starship Landing & Salvage

15–75°

11–1 o’clock

~10–16 km+

Beyond operational pads to segregate hot-work, decon and cutting from passenger ops; downrange so particulates and fumes carry east; direct back-haul into heavy manufacturing and ISRU cryo farm.

Industry Cargo Storage & Yard Construction

75–105° (ENE–ESE)

1–2 o’clock

~3–6 km+

On the east logistics crescent between city and industry, minimizing haul to heavy manufacturing and starport while keeping dusty staging downwind of hab.

Test Range / Proving Ground

75–105° (ENE–ESE)

1–2 o’clock

~10–16 km+

Placed beyond pads so trials run parallel to flight paths, not across them; downwind of city and upwind of landfill to keep noise/particulates off hab and arrays; operations scheduled around launch windows.

Waste / Landfill

105° (ESE)

2 o’clock

~6–10 km+

East of city so odors/dust track away under westerlies; co-located near MRF and industrial haul roads; safely outside starport approach centerlines.

Heavy Manufacturing Campus

105–150° (ESE–SSE)

2–3.5 o’clock

~3–12 km+

Downwind arc for “dirty” processes, with shortest run to starport and donor-salvage; buffered from PV/nuclear to the south by service corridors; keeps clean western sector free for ag and residences.

Nuclear

150–165° (SSE)

3.5–4 o’clock

~8–16 km

Downwind and well outside flight corridors; on competent ground and adjacent to the south power corridor to feed grid/battery nodes while maximizing standoff from hab and water fields.

Hydrogen/Electrolyzer & Thermal Storage

150–195° (SSE)

3.5–5 o’clock

~4–6 km

Co-sited between PV (SW) and nuclear (SE) to shorten electrical/thermal runs; downwind of city; isolated from starport ignition sources and from public traffic.

PV Solar Megafarms (A & B)

A: 165–225° B: 45–76°

A: 4–6 o’clock B: 6–8 o’clock

~5–10 km+

Southern exposure and large contiguous tracts; positioned away from starport dust plumes; flanked by battery nodes and the south power corridor; leaves clean western air for ag and north for water-ice haul.

Wastewater & Materials Recovery

5–6 o’clock

~4–6 km

Downwind and adjacent to PV/thermal storage for low-cost power; two-way material flows with landfill to the east and light industry to the west; avoids flight-path incursions.

Life-Support (A & B)

255–285° (WSW–WNW)

A: 6–7 o’clock B: 12–1 o’clock

~3–5 km

Dual-sited for redundancy: one on the quiet west for clean intake and protected service to hab; one near NE corridor to feed industry/starport quickly; both outside approach wedges and with easy valve isolation.

Light Industry Campus

255–285° (WSW–WNW)

7–8 o’clock

~3–5 km

Upwind, “clean-side” fabrication buffers the hab from ag; short hops to battery/data center; keeps heavy-dust processes shifted east with the manufacturing arc.

Shielded Data Center

255–285° (WSW–WNW)

7–8 o’clock

~5–7 km

Low-dust, thermally stable sector with strong power redundancy (PV + battery node 8 o’clock); far from explosive risk (ISRU/prop) and outside starport hazard radius.

Agricultural Industry

285–245° (WNW–NNW)

8–10 o’clock

~3–6 km

Clean-air band upwind of industry and downwind of water corridor; acts as buffer between hab and water-ice haul; avoids shading conflicts with PV to the south.

Water-Ice Mining Fields

285–245°

8–10 o’clock

~6–20 km+

Northwest arc targets shallow subsurface ice while keeping any blow-off north of the city latitude; aligned to a dedicated north resource corridor that never crosses the hab.

ISRU Cryo Farm

345–15° (NNW–NNE)

10–11 o’clock

~6–12 km

Upwind of city and outside public zones; shortest prop line to both donor-salvage and operational pads while maintaining standoff from hab and data center.

Settlement Cargo Storage & Yard — Construction

345–15° (NNW–NNE)

10–11 o’clock

~3–6 km

Staging for city builds on the quiet north edge so dust stays off hab; direct tie-in to ring-road and HWAC trunks without crossing starport approaches.

GSE & Spares Hubs (2×)

245° & 105° (NNW & ESE)

10 & 2 o’clock

~2–3 km

Twin depots on opposite sides reduce single-point failure: one near city/NNW for maintenance response, one ESE for starport/industry resupply; both offloaded from passenger flow.

Battery / Inverter Nodes (6×)

45°, 105°, 165°, 225°, 285°, 345°

12, 2, 4, 6, 8, 10 o’clock

~2–3 km

Hex-ring architecture shortens feeders to PV/nuclear/industry/starport while giving N–S/E–W redundancy; keeps high-energy equipment outside the hab boundary.

Comms / PNT / Met (8 posts)

45°, 90°, 135°, 180°, 225°, 270°, 315°, 0°

12, 1.5, 3, 4.5, 6, 7.5, 9, 10.5

~2–3 km

Even 45° spacing gives overlapping coverage for navigation and wind/dust monitoring; clear lines-of-sight to pads and approach gates without intruding on flight corridors.
