Venus · Dorsum · 401st largest named feature

Kadlu Dorsa

Eskimo thunder deity.

What Kadlu Dorsa is

Kadlu Dorsa is a dorsum — a ridge — on Venus, 500 km across, centred at 69.5° S, 172.0° W in the Barrymore quadrangle. It is the 401st largest named feature on Venus and the 82nd largest of its class there.

Where the name comes from

Eskimo thunder deity. The International Astronomical Union approved the name in 1997, under the theme it applies to every dorsum on Venus. Of the 99 features of this class catalogued on Venus, the naming categories run Slavic (9), Siberia (8), Greek (6), Lithuania (5).

What it would take to settle Kadlu Dorsa

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 69.5° S, 172.0° W.

What this spot has going for it is known ground 6,625 km from Vega 2 (1985). What works against it is water same as everywhere else on this world.

Computed from Kadlu Dorsa'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.
