Hagal Planitia
What Hagal Planitia is
Hagal Planitia is a planitia — a low plain — on Titan, 435 km across, centred at 60.6° S, 15.1° E. It is the 39th largest named feature on Titan and the 5th largest of its class there.
Where the name comes from
Planet from the Dune series; a jewel planet known for its quality quartz, and which is mined out in the time of Shaddam I. The International Astronomical Union approved the name in 2015, under the theme it applies to every planitia on Titan.
What it would take to settle Hagal 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 60.6° S, 15.1° E.
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 Hagal 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.
