Moytura Regio
What Moytura Regio is
Moytura Regio is a regio — a large area distinguished by its brightness or colour — on Europa, 483 km across, centred at 50.0° S, 65.7° E. It is the 58th largest named feature on Europa and the 8th largest of its class there.
Where the name comes from
Location of battles between the Fomorians and the Tautha de Danann. The International Astronomical Union approved the name in 1997, under the theme it applies to every regio on Europa. Of the 8 features of this class catalogued on Europa, the naming categories run Celtic (5), Wales (3).
What it would take to settle Moytura Regio
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 50.0° S, 65.7° E.
What this spot has going for it is water — same as everywhere else on this world. What works against it is radiation geometry — on the trailing hemisphere, which takes the brunt of the bombardment.
Computed from Moytura Regio'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.
