Acidalia Mensa
What Acidalia Mensa is
Acidalia Mensa is a mensa — a flat-topped elevation with cliff-like edges — on Mars, 227 km across, centred at 46.7° N, 25.3° W in the Mare Acidalium quadrangle. It is the 381st largest named feature on Mars and the 16th largest of its class there.
Where the name comes from
From classical albedo feature name. The International Astronomical Union approved the name in 2000, under the theme it applies to every mensa on Mars. Of the 38 features of this class catalogued on Mars, the naming categories run Greek (19), Latin (14), Roman (3), Slovenia (1).
What it would take to settle Acidalia Mensa
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 46.7° N, 25.3° W.
What this spot has going for it is known ground — 1,675 km from Mars Pathfinder (1997). What works against it is ground — mixed ground — a rim, a floor and slopes between them.
Computed from Acidalia Mensa'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.
