Niman Rupes
What Niman Rupes is
Niman Rupes is a rupes — a scarp or cliff — on Ceres, 45 km across, centred at 28.6° S, 60.1° E. It is the 60th largest named feature on Ceres and the 1st largest of its class there.
Where the name comes from
Hopi (SW USA) ritual ending the katsina (spiritual beings) season, celebrates the katsinasâ return to their spiritual home in July and their part in the blossoming of plant life. The International Astronomical Union approved the name in 2015.
What it would take to settle Niman Rupes
Ceres scores 43.8 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 28.6° S, 60.1° E.
What this spot has going for it is sunlight — 88% of the sunlight the sunniest latitude on Ceres gets. What works against it is ground — broken ground — hard to reach, and worth reaching for the shelter and the exposed strata.
Computed from Niman 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 Ceres (radiation geometry, earth link, known ground). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Ceres 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.
