About this model
Hubble at release (STS-31, 1990) is one of the 203 3D models Space Radar made itself: a space telescope, built in code from published dimensions and photographs, with no image-to-3D generator and no one else’s mesh.
Shape built from published dimensions and pictures; details simplified. It has 44,097 triangles in a 439 kB glTF file, and is 13 m across at full scale.
It is part of the map’s library; no object on the live map is drawn with it today.

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 (read 2026-11-03)
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).
The full record
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)
Where the map uses it. NOTHING YET, as a route on the map (`hubble` is the telescope there): the Hubble Space Telescope as it left Discovery on 25 April 1990, in the `hubble-deployment` Moment (release 1.7.7): the aperture door shut, the first (golden-yellow, ESA-built) solar arrays as their own parts, which the Moment poses stowed (scaled down along the tube, the masts folded along it) and unrolled, and the two high gain antenna booms as parts it folds along the tube and lets spring out. Loaded by id; NOT the model of the craft on the map (that is `hubble`, as it flew after Servicing Mission 4). Frame of this file: the long axis on +Y, the aperture door at +Y (here shut), the array masts on X, the antenna booms and the grapple fixtures on Z, metres, the origin on the tube's middle; stand it with keepXZ
Licence note. The shape is this project's, under this repository's licence, built from published numbers (facts). Every photograph it was compared with is NASA's (public domain).
