Ishak
What Ishak is
Ishak is a crater — a circular depression, almost always an impact scar — on Enceladus, 13.8 km across, centred at 47.6° N, 135.0° E. It is the 63rd largest named feature on Enceladus and the 31st largest of its class there.
Where the name comes from
Character in the tale "Isaac of Mosul and the Merchant." The International Astronomical Union approved the name in 2009, under the theme it applies to every crater on Enceladus.
What it would take to settle Ishak
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 47.6° N, 135.0° E.
What this spot has going for it is water — same as everywhere else on this world. What works against it is temperature — about -201 °C mean at this latitude.
Computed from Ishak'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.
