Lakhamu Fossa
What Lakhamu Fossa is
Lakhamu Fossa is a fossa — a long, narrow depression — on Ganymede, 370 km across, centred at 11.7° S, 132.8° E. It is the 43rd largest named feature on Ganymede and the 3rd largest of its class there.
Where the name comes from
Dragon monster, or divine natural force produced by Apsu and Tiamat. 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 Lakhamu Fossa
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 11.7° S, 132.8° E.
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 -157 °C mean at this latitude.
Computed from Lakhamu Fossa'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.
