Isbanir Fossa
What Isbanir Fossa is
Isbanir Fossa is a fossa — a long, narrow depression — on Enceladus, 170 km across, centred at 11.3° N, 1.7° E. It is the 11th largest named feature on Enceladus and the 3rd largest of its class there.
Where the name comes from
Fakir Taj's home; may be ancient Ctesiphon. The International Astronomical Union approved the name in 1982, under the theme it applies to every fossa on Enceladus.
What it would take to settle Isbanir Fossa
Enceladus scores 54.8 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 11.3° N, 1.7° E.
What this spot has going for it is sunlight — 98% of the sunlight the sunniest latitude on Enceladus gets. What works against it is temperature — about -194 °C mean at this latitude.
Computed from Isbanir Fossa's catalogued latitude, longitude and feature class — 68% of the model's weight had a basis here, and 3 axes were dropped as not applicable to Enceladus (radiation geometry, earth link, known ground). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Enceladus 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.
