## 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 NSSDCA's dimensions and NASA's and the Smithsonian's photographs (public domain, CC0).

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)

## Dimensions

- Height: 3 m
- Footpads: 4.3 m
- Panel: 0.855 m²

Source: NSSDCA, Surveyor 1 (https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=1966-045A) and Surveyor 3 (id=1967-035A), as the procedural shape cites them (scene/models.js buildSurveyor: '3 m tall, 4.3 m across the footpads', the 0.855 m2 array). Wikipedia, 'Surveyor 3', https://en.wikipedia.org/wiki/Surveyor_3, OPENED 2026-10-20: 'The sampler was mounted below the television camera and consisted primarily of a scoop approximately 4.7 inches (120 mm) long and 2.0 inches (50 mm) wide'; 'The scoop was mounted on a pantograph arm that could be extended about 5 feet (1.5 m)'. OURS: the frame's corners 0.78 m out and 0.72 m up, the compartments' and tanks' sizes, the panel's and the planar array's angles, every tube's size
