About this model
SLIM 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 13,080 triangles in a 114 kB glTF file, and is 2.7 m across at full scale.
It is part of the map’s library; no object on the live map is drawn with it today.

JAXA, press conference of 25 January 2024, isas.jaxa.jp/en/outreach/announcements/files/SLIM-pressconf-2024…, OPENED 2026-10-20: 'the final attitude of the spacecraft is believed to be an almost vertical position with the main engine facing upwards and the solar panels facing west'; 'causing the nozzle to break and fall, resulting in the loss of most of the thrust generated by the main engine on the -X side'. OURS: which cited side is which (2.7 m along the engines, 2.4 m across, 1.7 m from the cells to the legs, read off the media kit's figures), the 12 degree lean, every part's size (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 JAXA's published dimensions; compared with a photograph of JAXA's model by Artem.G (CC BY 4.0).
The full record
built by this project in code (release 1.3.0 stage W1-c's part library, lib.py, and one script a craft, 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 (NASA's 3D Resources, 1 583 paths, and NASA Science's 3D models have none of this craft; read 2026-10-20)
Where the map uses it. the slim landing site (registry/sites.yaml), near Shioli crater: JAXA's SLIM as it came to rest, standing on its nose with its engines up and one nozzle lost. It was the generic lander, which is still what is drawn while this file is on its way; public #1134
Licence note. No JAXA picture or model is in the file, on a sheet or derived from: JAXA's figures and its rendering of the landed attitude were looked at only. The one picture the shape was compared with is a photograph of JAXA's quarter-scale model at Expo 2025 by Commons user Artem.G under CC BY 4.0. The shape is this project's, under this repository's licence, built from published numbers (facts). NO LOGO AND NO LETTERING is on the mesh.
