Bigeh Facula

Island where Hapi, Egyptian Nile god, resided.

What Bigeh Facula is

Bigeh Facula is a facula — a bright spot — on Ganymede, 224 km across, centred at 29.0° N, 94.3° W. It is the 54th largest named feature on Ganymede and the 8th largest of its class there.

Where the name comes from

Island where Hapi, Egyptian Nile god, resided. The International Astronomical Union approved the name in 2000, under the theme it applies to every facula on Ganymede.

What it would take to settle Bigeh Facula

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 29.0° N, 94.3° W.

What this spot has going for it is radiation geometry under closed field lines, the shielded part of the only magnetosphere on any moon. What works against it is temperature about -160 °C mean at this latitude.

Computed from Bigeh Facula'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.
