Elam Sulci
What Elam Sulci is
Elam Sulci is a sulcus — a set of parallel grooves and ridges — on Ganymede, 1,500 km across, centred at 60.0° N, 160.0° E. It is the 28th largest named feature on Ganymede and the 20th largest of its class there.
Where the name comes from
Ancient Babylonian seat of sun worship, in present-day Iran. The International Astronomical Union approved the name in 1985, under the theme it applies to every sulcus on Ganymede. Of the 35 features of this class catalogued on Ganymede, the naming categories run Assyro-Babylonian (13), Greek (7), Sumerian (7), Babylon (3).
What it would take to settle Elam Sulci
Ganymede scores 55 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 60.0° N, 160.0° E.
What this spot has going for it is water — same as everywhere else on this world. What works against it is radiation geometry — inside the open-field polar cap, where the plasma gets down.
Computed from Elam Sulci'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 Ganymede (earth link, known ground). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Ganymede 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.
