Palus Putredinis
What Palus Putredinis is
Palus Putredinis is a palus — a small dark plain — on The Moon, 181 km across, centred at 27.4° N, 0.0° E in the Montes Apenninus quadrangle. It is the 130th largest named feature on The Moon and the 2nd largest of its class there.
Where the name comes from
"Marsh of Decay." The International Astronomical Union approved the name in 1935, under the theme it applies to every palus on The Moon.
What it would take to settle Palus Putredinis
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 27.4° N, 0.0° E.
What this spot has going for it is earth link — near side — Earth stands 63° above the horizon and never moves. What works against it is water — outside the ice-bearing latitudes.
Computed from Palus Putredinis'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.
