The Moon · Dorsum · 251st largest named feature

Dorsum Grabau

Amadeus William; American paleontologist (1870-1946).

What Dorsum Grabau is

Dorsum Grabau is a dorsum — a ridge — on The Moon, 124 km across, centred at 29.8° N, 14.2° W in the Timocharis quadrangle. It is the 251st largest named feature on The Moon and the 17th largest of its class there.

Where the name comes from

Amadeus William; American paleontologist (1870-1946). The International Astronomical Union approved the name in 1976, under the theme it applies to every dorsum on The Moon. Of the 39 features of this class catalogued on The Moon, the naming categories run Great Britain (8), American (6), Germany (5), Switzerland (4).

What it would take to settle Dorsum Grabau

The Moon scores 29.1 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 29.8° N, 14.2° W.

What this spot has going for it is earth link near side — Earth stands 57° above the horizon and never moves. What works against it is water outside the ice-bearing latitudes.

Computed from Dorsum Grabau's catalogued latitude, longitude and feature class — 84% of the model's weight had a basis here, and one axis was dropped as not applicable to The Moon (radiation geometry). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on The Moon 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.
