About Space Radar Models
Free 3D models of real spacecraft, built by the Space Radar team from published dimensions and photographs: turn them in 3D, see them live, download the glTF.
Space Radar is a free, open-source 3D map of everything in orbit. Where no agency publishes a 3D model of a craft under a free licence, the team builds one: from the published dimensions, in code, compared with photographs from several sides. This catalog lists those models, and only those. The agencies’ own models that the map also uses (NASA 3D Resources, the PDS shape models of asteroids and moons) are their makers’, and you should get them from them.
Honest about what each one is
Every model says how it was made and what it simplifies, in one sentence under its name. Built from dimensions means it was drawn in code from published numbers and photographs, with no image-to-3D generator and no one else’s mesh. Generated, then repaired means the body began as a mesh that TRELLIS (Microsoft Research, MIT licence) made from one or two public-domain NASA pictures, then measured, repaired and completed in code. Each page lists the dimensions with their sources and the pictures the shape was compared with; none of those pictures is in the file.
The licence
The models are under the MIT licence of the Space Radar repository: use them, change them and share them, also commercially, and keep the credit line each page gives. The files are glTF 2.0 binaries compressed with meshopt.
Downloads
Each file downloads from the project’s GitHub repository, with Space Radar’s own forge as a mirror. The catalog is rebuilt from the project’s registry every time the map is deployed, so a new model appears here with no page written by hand.
The viewer
Each model has a small viewer on the map’s own site, at www.spaceradar.ai/model/?id=…, that anyone may embed. It loads nothing from a third party and stores nothing. How to embed it.
For readers that are machines
Every page is plain HTML that needs no script, and every model is also Markdown at its address with .md added. /llms.txt lists the models, /llms-full.txt holds the full text, and the feeds are RSS, Atom and JSON Feed. Search and AI crawlers are welcome.
