Mars · Labyrinthus · 105th largest named feature

Adamas Labyrinthus

Classical albedo feature name; "A River of Diamonds"; today's River Sarbarnarekha in India.

What Adamas Labyrinthus is

Adamas Labyrinthus is a labyrinthus — a complex of intersecting valleys or ridges — on Mars, 853 km across, centred at 35.7° N, 105.1° E in the Casius quadrangle. It is the 105th largest named feature on Mars and the 2nd largest of its class there.

Where the name comes from

Classical albedo feature name; "A River of Diamonds"; today's River Sarbarnarekha in India. The International Astronomical Union approved the name in 1982, under the theme it applies to every labyrinthus on Mars. Of the 6 features of this class catalogued on Mars, the naming categories run Latin (3), Greek (2), Romania (Rumania) (1).

What it would take to settle Adamas Labyrinthus

Mars scores 26.6 as a world. That number is the same for every square metre of it — but sunlight, water, radiation and the ground under your feet are not. This is the same question asked at 35.7° N, 105.1° E.

What this spot has going for it is known ground 675 km from Zhurong (2021). What works against it is water outside the ice-bearing latitudes.

Computed from Adamas Labyrinthus's catalogued latitude, longitude and feature class — 74% of the model's weight had a basis here, and 2 axes were dropped as not applicable to Mars (radiation geometry, earth link). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Mars and are already counted in the world's own index, not again here.

What this cannot see: elevation. Slope, local shadowing and the polar “peaks of eternal light” — ridge tops near the poles of a barely tilted world that catch sun almost continuously while a crater floor kilometres away never does — need a terrain model this does not have. Where a real mission targets a pole, that is usually why.
