About this model
Tianzhou is one of the 203 3D models Space Radar made itself: a crewed craft or station, built in code from published dimensions and photographs, with no image-to-3D generator and no one else’s mesh.
Shape built from published dimensions and pictures; details simplified. It has 7,536 triangles in a 47 kB glTF file, and is 15 m across at full scale.
It is part of the map’s library; no object on the live map is drawn with it today.

CMSA's English page, en.cmse.gov.cn/constitutes/cargovehiclesystem, opened 2026-10-13, carries NO dimensions; the peer-reviewed paper (Lei et al., doi 10.34133/space.0006) answered 403 and WAS NOT READ. CGTN (China's state broadcaster), news.cgtn.com/news/2021-05-30/China-Space-Station-What-does-Tian…, opened 2026-10-13: 'It is composed of two segments, a cargo compartment with a diameter of 3.35 meters and a propulsion compartment with a diameter of 2.8 meters.' and 'a length of 10.6 meters and a width of 14.9 meters when its two solar arrays are fully deployed'.

How it was made
Built in code from published dimensions and photographs, with no image-to-3D generator and no one else’s mesh. 3D model: built by Space Radar from the published dimensions of the Tianzhou cargo ship.
The full record
built by this project in code (the private tool model-from-images: assemble.py, from a yaml of primitives), from the cited dimensions and the pictures under `references`; no image-to-3D model was used, and no published mesh
Where the map uses it. any record on the stations layer whose name has the word TIANZHOU (today TIANZHOU-10): China's cargo ship. It was, and while this file is on its way still is, the procedural Tianzhou (scene/models.js `tianzhou`); public #942
Licence note. No picture ships and none was traced: CMSA's own pictures are not free, and the one render looked at (named under `references`) is CC BY-SA 4.0, used for nothing but which part is where; the shape is this project's, under this repository's licence
