## 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 NASA's and ESA's published dimensions; compared with NASA's photographs of the release on 25 April 1990 (public domain).

built by this project in code (tools/hubble-builder/hubble_sts31.py, derived from release 1.3.0's builder of `hubble`, which is kept with that stage's notes); no image-to-3D model was used, and no published mesh: NASA's 3D Resources and NASA Science's 3D models have none of this craft (read 2026-10-20, again 2026-11-03)

## Dimensions

- Length: 13.2 m
- Diameter: 4.2 m
- Array length: 7.56 m
- Array width: 2.45 m

Source: as `hubble` (ESA/Hubble fact sheet, opened 2026-10-20; NASA's media guide section 5); the arrays here are built to ESA's 2.45 x 7.56 m, NASA gives 7.1 x 2.6 m
