Henbury
What Henbury is
Henbury is a crater — a circular depression, almost always an impact scar — on Mars, 25.4 km across, centred at 63.5° S, 147.7° W in the Phaethontis quadrangle. It is the 1179th largest named feature on Mars and the 536th largest of its class there.
Where the name comes from
Town in Australia. The International Astronomical Union approved the name in 2007, under the theme it applies to every crater on Mars. Of the 1237 features of this class catalogued on Mars, the naming categories run United States (137), Russia (110), American (62), Great Britain (52).
What it would take to settle Henbury
Mars scores 26.6 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 63.5° S, 147.7° W.
What this spot has going for it is water — inside the polar zone where Mars keeps its ice. What works against it is sunlight — 54% of the sunlight the sunniest latitude on Mars gets.
Computed from Henbury's catalogued latitude, longitude and feature class — 74% of the model's weight had a basis here, and 2 axes were dropped as not applicable to Mars (radiation geometry, earth link). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Mars 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.
