Ariadnes Colles
What Ariadnes Colles is
Ariadnes Colles is a collis — a small hill or knob — on Mars, 188 km across, centred at 34.5° S, 172.8° E in the Eridania quadrangle. It is the 419th largest named feature on Mars and the 15th largest of its class there.
Where the name comes from
Classical albedo feature name. The International Astronomical Union approved the name in 1982, under the theme it applies to every collis on Mars. Of the 22 features of this class catalogued on Mars, the naming categories run Greek (12), Latin (7), Roman (2), Turkey (1).
What it would take to settle Ariadnes Colles
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 34.5° S, 172.8° E.
What this spot has going for it is sunlight — 84% of the sunlight the sunniest latitude on Mars gets. What works against it is water — outside the ice-bearing latitudes.
Computed from Ariadnes Colles'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.
