Fagaloa Sinus
What Fagaloa Sinus is
Fagaloa Sinus is a sinus — a bay-shaped dark plain — on Titan, 33 km across, centred at 82.9° N, 39.5° E. It is the 233rd largest named feature on Titan and the 25th largest of its class there.
Where the name comes from
Bay in Samoa (Upolu Island). The International Astronomical Union approved the name in 2020, under the theme it applies to every sinus on Titan. Of the 28 features of this class catalogued on Titan, the naming categories run Canada (3), Japan (2), Namibia (1), Scotland (1).
What it would take to settle Fagaloa Sinus
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 82.9° N, 39.5° E.
What this spot has going for it is water — inside the polar zone where Titan keeps its ice. What works against it is temperature — about -180 °C mean at this latitude.
Computed from Fagaloa Sinus'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.
