Autonoe Linea

Daughter of Harmonia and Cadmus in Greek mythology.

What Autonoe Linea is

Autonoe Linea is a linea — a long, dark or bright marking — on Europa, 760 km across, centred at 18.2° N, 165.1° W. It is the 53rd largest named feature on Europa and the 40th largest of its class there.

Where the name comes from

Daughter of Harmonia and Cadmus in Greek mythology. The International Astronomical Union approved the name in 2000, under the theme it applies to every linea on Europa. Of the 49 features of this class catalogued on Europa, the naming categories run Greek (38), Celtic (6), England (3), France (1).

What it would take to settle Autonoe Linea

Europa scores 60.9 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 18.2° N, 165.1° W.

What this spot has going for it is water same as everywhere else on this world. What works against it is temperature about -154 °C mean at this latitude.

Computed from Autonoe Linea'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 Europa (earth link, known ground). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Europa 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.
