## 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 eoPortal's published dimensions; compared with the operator's pictures, looked at only.

built by this project in code (release 1.3.0's part library, lib.py and parts.py, kept with the stage's notes in ~/space-radar-handoff/release-1.4/r14-m5/build, one script a craft), 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, read 2026-10-27) has none of this craft, and no operator of it was found to publish a model under a free licence (searched 2026-10-27)

We built 20 x 26.7 x 44 cm. OURS: every antenna's place and size, the whips' length and angle, the boom's length and width, the nozzle
