The Moon · Rima · 1828th largest named feature

Rima Marcello

Italian male name.

What Rima Marcello is

Rima Marcello is a rima — a fissure — a collapsed lava channel or a crack in the crust — on The Moon, 4 km across, centred at 18.6° N, 27.7° E in the Mare Serenitatis quadrangle. It is the 1828th largest named feature on The Moon and the 111th largest of its class there.

Where the name comes from

Italian male name. The International Astronomical Union approved the name in 1976, under the theme it applies to every rima on The Moon. Of the 112 features of this class catalogued on The Moon, the naming categories run Germany (19), France (19), Greek (17), Italy (12).

What it would take to settle Rima Marcello

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 18.6° N, 27.7° E.

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 Rima Marcello'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.
