About this model
Chang'e 4 is one of the 203 3D models Space Radar made itself: a lander or rover, 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 16,223 triangles in a 121 kB glTF file, and is 4.8 m across at full scale.
It is part of the map’s library; no object on the live map is drawn with it today.

OURS: the body 2.5 m across its big faces and 1.25 m tall, the legs on the corners, the panels 1.55 x 1.1 m sloping 20 to 24 degrees down, the ramps 1.9 m long, the columns, the mast, the dish, the whip and the LFS antennas' length (2.2 m as Yutu-2's pictures show them) (read 2026-10-20)
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 published dimensions and pictures (CNSA/Siyu Zhang/Kevin M. Gill, CC BY 2.0; CNSA, CC BY 4.0).
The full record
built by this project in code (release 1.3.0 stage W3-c's scripts, one a craft, on W1-c's part library, kept with the stage's notes), from the cited dimensions and the pictures under `references`; no image-to-3D model was used, and no published mesh (CNSA publishes none under terms that allow a derivative, and NASA's 3D Resources and NASA Science's 3D models have none of these craft; read 2026-10-20)
Where the map uses it. the change-4 landing site (registry/sites.yaml), Von Kármán crater on the far side: the Chang'e 4 lander as Yutu-2 photographed it, both ramps down, its three low-frequency antennas out. It was the generic lander, which is still what is drawn while this file is on its way; public #1125
Licence note. CC BY 2.0 (Yutu-2's pictures of the lander, CSNA/Siyu Zhang/Kevin M. Gill) and CC BY 4.0 (CNSA): looked at, with credit; nothing of them is in the file. The mock-ups' photographs are CC BY-SA 4.0 and were looked at only. The shape is this project's, under this repository's licence, built from published numbers (facts).
