Falga Regio
What Falga Regio is
Falga Regio is a regio — a large area distinguished by its brightness or colour — on Europa, 2,500 km across, centred at 30.0° N, 150.0° E. It is the 4th largest named feature on Europa and the 1st largest of its class there.
Where the name comes from
In Celtic mythology, island where Midir had a stronghold. The International Astronomical Union approved the name in 2007, 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 Falga 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 30.0° N, 150.0° 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 boundary between the leading and trailing hemispheres.
Computed from Falga 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.
