Telegonus Mensae
What Telegonus Mensae is
Telegonus Mensae is a mensa — a flat-topped elevation with cliff-like edges — on Io, 330 km across, centred at 52.4° S, 115.4° W. It is the 34th largest named feature on Io and the 1st largest of its class there.
Where the name comes from
Egyptian king whom Io married. The International Astronomical Union approved the name in 2000, under the theme it applies to every mensa on Io. Of the 9 features of this class catalogued on Io, the naming categories run Greek (7), India (1), Italy (1).
What it would take to settle Telegonus Mensae
Io scores 76.7 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 52.4° S, 115.4° W.
What this spot has going for it is ground — mixed ground — a rim, a floor and slopes between them. What works against it is water — same as everywhere else on this world.
Computed from Telegonus Mensae'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 Io (earth link, known ground). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Io 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.
