Agrona Linea
What Agrona Linea is
Agrona Linea is a linea — a long, dark or bright marking — on Venus, 2,300 km across, centred at 40.0° N, 80.0° W in the Beta Regio quadrangle. It is the 55th largest named feature on Venus and the 3rd largest of its class there.
Where the name comes from
Welsh goddess of slaughter, destroyer of life. The International Astronomical Union approved the name in 2006, under the theme it applies to every linea on Venus. Of the 17 features of this class catalogued on Venus, the naming categories run Celtic (3), Roman (2), Hawaii (1), Wales (1).
What it would take to settle Agrona Linea
Venus scores 43 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 40.0° N, 80.0° W.
What this spot has going for it is known ground — 1,377 km from Venera 9 (1975). What works against it is water — same as everywhere else on this world.
Computed from Agrona Linea'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 Venus (radiation geometry, earth link). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Venus 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.
