Thera Macula
What Thera Macula is
Thera Macula is a macula — a dark spot — on Europa, 95 km across, centred at 46.7° S, 178.8° E. It is the 79th largest named feature on Europa and the 3rd largest of its class there.
Where the name comes from
Greek; place where Cadmus stopped in his search for Europa. The International Astronomical Union approved the name in 1979, under the theme it applies to every macula on Europa.
What it would take to settle Thera Macula
Europa scores 60.9 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° S, 178.8° E.
What this spot has going for it is water — same as everywhere else on this world. What works against it is temperature — about -164 °C mean at this latitude.
Computed from Thera Macula's catalogued latitude, longitude and feature class — 84% of the model's weight had a basis here, and 2 axes were dropped as not applicable to Europa (earth link, known ground). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Europa 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.
