Zu Fossae
What Zu Fossae is
Zu Fossae is a fossa — a long, narrow depression — on Ganymede, 2,900 km across, centred at 38.5° N, 150.5° W. It is the 15th largest named feature on Ganymede and the 2nd largest of its class there.
Where the name comes from
Dragon of chaos slain by Marduk. The International Astronomical Union approved the name in 1985, under the theme it applies to every fossa on Ganymede.
What it would take to settle Zu Fossae
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 38.5° N, 150.5° W.
What this spot has going for it is water — same as everywhere else on this world. What works against it is temperature — about -163 °C mean at this latitude.
Computed from Zu Fossae'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.
