Lagado Planitia
What Lagado Planitia is
Lagado Planitia is a planitia — a low plain — on Phobos, 4 km across, centred at 19.0° N, 129.0° E. It is the 7th largest named feature on Phobos and the 1st largest of its class there.
Where the name comes from
Fictional city in Jonathan Swift's Gulliver's Travels, ruled by a tyrannical king from the flying island Laputa. The International Astronomical Union approved the name in 2011.
What it would take to settle Lagado Planitia
Phobos scores 48.7 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 19.0° N, 129.0° E.
What this spot has going for it is sunlight — 95% of the sunlight the sunniest latitude on Phobos gets. What works against it is water — same as everywhere else on this world.
Computed from Lagado Planitia'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 Phobos (radiation geometry, earth link, known ground). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Phobos 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.
