Arrakis Planitia
What Arrakis Planitia is
Arrakis Planitia is a planitia — a low plain — on Titan, 337 km across, centred at 78.4° S, 117.0° W. It is the 50th largest named feature on Titan and the 7th largest of its class there.
Where the name comes from
Planet from the Dune series; home of the Fremen, a group of fictional people whose culture revolves around preservation and conservation of water, which is a rare commodity on the planet. The International Astronomical Union approved the name in 2010, under the theme it applies to every planitia on Titan.
What it would take to settle Arrakis Planitia
Titan scores 32.6 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 78.4° S, 117.0° W.
What this spot has going for it is ground — flat ground — the easiest thing to land on and build across. What works against it is temperature — about -180 °C mean at this latitude.
Computed from Arrakis Planitia's catalogued latitude, longitude and feature class — 74% of the model's weight had a basis here, and 2 axes were dropped as not applicable to Titan (radiation geometry, earth link). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Titan 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.
