Polelya Macula
What Polelya Macula is
Polelya Macula is a macula — a dark spot — on Titan, 175 km across, centred at 50.0° N, 56.0° W. It is the 91st largest named feature on Titan and the 4th largest of its class there.
Where the name comes from
East Slavic god of matrimonial happiness. The International Astronomical Union approved the name in 2007, under the theme it applies to every macula on Titan. Of the 7 features of this class catalogued on Titan, the naming categories run Slavic (2), Greek (1), Aztec (1), India (1).
What it would take to settle Polelya Macula
Titan scores 32.6 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 50.0° N, 56.0° W.
What this spot has going for it is ground — flat ground — the easiest thing to land on and build across. What works against it is temperature — about -179 °C mean at this latitude.
Computed from Polelya Macula'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 Titan (radiation geometry, earth link). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Titan 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.
