## 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 a photograph of a model (CC0 by Blervis; McDowell's GCAT, CC BY).

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 pictures under `references`; no image-to-3D model was used, and no published mesh (NASA Science's 3D models and NASA's 3D Resources have none of this craft, and the maker and the operator publish none under terms that allow a derivative); the layout and its sources are under `references` and `dimensions`

## Dimensions

- Length: 1.2 m

TWO PAGES DISAGREE on the mass (1 200 and 1 700 kg): not used for the shape. NOT PUBLISHED, OURS: the box's width, the phased face's size and element count, the panels' width, the yokes, the thrusters.
