Where is Haulani on Ceres?
Haulani is centered at 5.8° north, 10.77° east, just north of the equator. The International Astronomical Union named it in 2015 after Haulani, the Hawaiian goddess of plants.
Why is Haulani interesting?
Because it is young. NASA calls it one of the youngest craters on Ceres, with sharp rims, an outline more polygon than circle, and pitted ground that probably formed when water in the crust vaporized in the impact. Landslides have run down from its rim, smooth material and a ridge stand on its floor, and rays of bluish material spread out from it. Counting the small craters on top of it puts its age at a few million years, against the hundreds of millions of the great basins.
What does Haulani look like as a 3D print?
A deep, crisp bowl. Its entry frames about 44 kilometers, so the crater fills most of the view, and on a model 200 millimeters across the relief in that view comes out at about 20 millimeters at true scale. The landslides and the ridge on its floor print; the blue rays are color, not relief, and do not.
What is OrbitStudio?
OrbitStudio turns real elevation data into 3D-printable models. You pick a region of Ceres on a globe or a flat map, choose a jigsaw puzzle or a solid ornament, and get ready-to-print files with terrain and borders already separated and colored. No CAD, no mesh repair. The heights come from the shape model NASA's Jet Propulsion Laboratory made from Dawn's images, on a 100-meter grid.
Trying it is free and needs no account: pick a region, generate it and turn it around in 3D. Downloading the model — STL files and pre-colored 3MF files for Bambu Studio or OrcaSlicer — takes a Plus or Merchant plan, or one credit from a pass. The generator covers the Moon, Mars, Mercury, Venus, Pluto and Charon too.
Other landmarks
The night sky, too
OrbitStudio Sky, the night-sky tool, turns the sky over any place, on any date from 1900 to 2100, into a 3D-printable star map. Its STL is free.
