## 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 NASA renders and drawings of PACE.

built by this project in code (the private tool model-from-images: assemble.py, from a yaml of primitives), from the cited dimensions and the NASA pictures under `references`; no image-to-3D model was used, and no published mesh (NASA's 3D Resources, science.nasa.gov/3d-resources and github.com/nasa/NASA-3D-Resources, searched 2026-10-13, has none of this craft)

- Length: 3.2 m
- Width: 1.5 m

Just below is the Ocean Color Instrument'; 'Overall observatory dimensions are 1.5 m by 1.5 m by 3.2 m (4.9 x 4.9 x 10.5 ft)'. NASA's PACE blog, https://science.nasa.gov/blogs/pace/2024/02/08/meet-nasas-pace-spacecraft-science-instruments/, opened 2026-10-13: 'The PACE spacecraft stands about 10 feet tall'; 'The spacecraft's solar array is made of three panels. The array measures 100 inches by 173 inches' (2.54 x 4.39 m). THE ISSUE'S eoPortal LINK IS ANOTHER PACE (a 2U CubeSat of 100 x 100 x 243 mm) and gave nothing. NOT CITED, read off NASA's renders: the split of the 3.2 m into a 2.3 m bus and the instrument end, the Ocean Color Instrument's 0.9 x 0.9 x 0.8 m and its place, the Earth shield's 1.4 m, the dish's 0.6 m, both polarimeters' sizes and places, the wing's beam
