Callisto · Catena · 7th largest named feature

Gomul Catena

Norse river.

What Gomul Catena is

Gomul Catena is a catena — a chain of craters — on Callisto, 343 km across, centred at 35.5° N, 47.1° W. It is the 7th largest named feature on Callisto and the 2nd largest of its class there.

Where the name comes from

Norse river. The International Astronomical Union approved the name in 1997, under the theme it applies to every catena on Callisto.

What it would take to settle Gomul Catena

Callisto scores 44.6 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 35.5° N, 47.1° W.

What this spot has going for it is water same as everywhere else on this world. What works against it is ground mixed ground — a rim, a floor and slopes between them.

Computed from Gomul Catena'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 Callisto (earth link, known ground). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Callisto 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.
