A single bounded area of Acidalia Planitia, Mars — sited on purpose where no rover, lander, heritage site, or published private landing zone has any prior interest. It isn't a blank grid: it's a garden-suburb settlement plan drawn over the real Martian surface — a central diamond spaceport, a civic green at its heart, boulevards carrying power & utility easements, and homestead long-lots of 40 acres each woven between parks, greens and ice ponds. Roughly a fifth of the tract is public open space, and every road bends around the craters — which keep their real Martian names. Zoom in over the actual terrain and stake an open lot.
Why here
An honest first claim — no other interested parties
The strongest good-faith homestead claim is one nobody else is contesting. So the founding tract sits in the open northern lowlands of Acidalia Planitia — flat, with shallow ground ice within reach — and well away from every government mission site and every private candidate-landing cluster. It's laid out the way a good town is: streets that bend around the natural craters, a fifth of the ground kept as parks and commons, and homesteads gathered into neighbourhoods rather than a bare checkerboard.

Founding Tract One · Acidalia Planitia, Mars · IAU areographic, +East |
Centre 41.00°N, 337.00°E · ~285 × 114 km · ≈ 32,400 km² (about the size of Maryland) · ~0.02% of the Martian surface
Each homestead lot is a 40-acre long-lot — a 2:1 rectangle, ≈569 × 285 m. A diamond spaceport core sits inside Founders' Green, the civic commons; boulevards carry the power & utility easements; the natural craters are kept as reserves with a rim drive circling each, so no road runs through one. Rights-of-way, the commons, the parks and the crater reserves are dedicated and not claimable — every numbered homestead or commercial lot is a full 40 acres.

File your claim over the real surface
This is where you stake your homestead. The plat is drawn over real NASA Mars imagery, so you're choosing over the actual Acidalia terrain. Start at the whole tract; click (or double-click) to zoom from quarters → districts → sections → lots, then click an open lot to stake it — it turns green. Gold lots are commercial / depot frontage; parchment lots are residential long-lots; grey lots are already claimed. The rust diamond is the reserved spaceport inside Founders' Green; the parks and ice ponds are public open space; and the craters keep their real Martian names, each circled by a rim drive so the roads bend around them. Use the mini-map and breadcrumb to keep your bearings.
Zoom in to lot view to inspect and stake individual long-lots.
👆 Each lot is a 40-acre homestead long-lot. Click open lots to stake them — stake adjacent lots to build a larger holding, or grab a commercial frontage lot on a boulevard.

✓ Plat captured — it'll be saved to this claim's file.
Opening a claim starts your 19-instrument claim file and a 24-month public edital. No legal title is conveyed; recognition is not guaranteed; not an investment.
Base imagery: NASA/JPL/USGS Mars Viking MDIM21 colour mosaic (≈232 m/px) — the real Acidalia surface. At the deepest zoom, where the global mosaic runs out of native resolution, a light cartographic micro-relief is added so each plot reads as its own ground; it is illustrative, not photographic.
Crater names (Lomonosov, Kunowsky, Skłodowska, Aranda, Bamberg, Bordeaux, Gasa, Liberta, Cádiz) are real Martian crater names from the IAU Gazetteer of Planetary Nomenclature — most from the Mare Acidalium quadrangle that contains Acidalia Planitia (large craters named for scientists, small craters for Earth towns). Their placement on this planned tract is cartographic, not a georeferenced survey of those specific craters.
The plat is a survey diagram (claim-file instrument #1 — Plat of Survey, and #10 — Memorial Descritivo), not a photograph and not a legal title. The garden-suburb plan — spaceport core, Founders' Green, parks, ice ponds, boulevards, crater reserves with their rim drives, and the section/district grid carrying the power & utility easements — models real homestead and town-site survey practice; the core, the commons, the parks, the crater reserves and all rights-of-way are reserved and not claimable. Roughly a fifth of the tract is dedicated public open space.

Stake your forty in the founding tract
Pick your open 40-acre lots, capture the plat into your claim file, and open the 24-month process. A documented good-faith homestead claim and a collectible — not a legal title, not an investment.
No conveyance of legal title. The 1967 Outer Space Treaty (Art. II) bars national appropriation of celestial bodies, and no sovereign, court, or land registry currently has jurisdiction to grant or enforce private title to land on the Moon, Mars, or any celestial body. Spaceclaims does not and cannot convey legal ownership or any presently-enforceable property right.
What you purchase. A claim-documentation and registry service — the preparation, notarization support, public publication, opposition-period adjudication, and continuous-possession recordkeeping of a good-faith homestead claim — together with a collectible certificate. It is a record of your claim and intent, not a title.
Not an investment; not a security. Your payment is not an investment of money in a common enterprise and carries no expectation of profit from our efforts. We make no representation as to resale value, appreciation, or return. The claim is not offered as a security and is not registered with the SEC, any state regulator, the Brazilian CVM, or any other authority.
No guarantee of recognition; no sovereignty; not legal advice. We model the process on frameworks in which documented good-faith possession was sometimes later recognized, but we do not guarantee any authority will ever recognize your claim. No Spaceclaims claim asserts national sovereignty. Nothing here is legal, tax, or financial advice.
