Bayta Fretum
What Bayta Fretum is
Bayta Fretum is a fretum — a strait — a narrow channel connecting two larger bodies of liquid — on Titan, 165 km across, centred at 73.0° N, 48.8° E. It is the 97th largest named feature on Titan and the 3rd largest of its class there.
Where the name comes from
Bayta Darell, fictional character in Isaac Asimov's Foundation Series, wife of the Trader Tran Darell and grandmother of famous author Arcadia âArcadyâ Darell. The International Astronomical Union approved the name in 2015, under the theme it applies to every fretum on Titan.
What it would take to settle Bayta Fretum
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 73.0° N, 48.8° E.
What this spot has going for it is water — inside the polar zone where Titan keeps its ice. What works against it is temperature — about -180 °C mean at this latitude.
Computed from Bayta Fretum'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.
