La Dauphine Rupes
What La Dauphine Rupes is
La Dauphine Rupes is a rupes — a scarp or cliff — on Mercury, 252 km across, centred at 66.3° N, 26.6° W in the Borealis quadrangle. It is the 80th largest named feature on Mercury and the 39th largest of its class there.
Where the name comes from
French; royal ship used for a voyage in search of the eastern coast of Asia, determined that North America was not an extension of Asia, 1524. The International Astronomical Union approved the name in 2014, under the theme it applies to every rupes on Mercury. Of the 66 features of this class catalogued on Mercury, the naming categories run England (11), United States (6), The Netherlands (Dutch) (4), France (4).
What it would take to settle La Dauphine Rupes
Mercury scores 46 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 66.3° N, 26.6° W.
What this spot has going for it is temperature — about 99 °C mean at this latitude. What works against it is water — outside the ice-bearing latitudes.
Computed from La Dauphine Rupes's catalogued latitude, longitude and feature class — 68% of the model's weight had a basis here, and 3 axes were dropped as not applicable to Mercury (radiation geometry, earth link, known ground). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Mercury 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.
