About this model
IRIS 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 13,298 triangles in a 114 kB glTF file, and is 3.6 m across at full scale.
On Space Radar’s live map it is drawn for the object with NORAD catalogue number 39197, where its published orbit puts it now. Open it on the map.

Panels built 1.30 x 0.65 m (the 1.7 m2 the paper gives needs 0.65). OURS: the bus 0.98 m across and 0.46 m long, the tube 0.30 m, the instrument box, every small part (read 2026-10-20)
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 De Pontieu et al. (2014)'s published dimensions; compared with NASA's photographs (public domain).
The full record
built by this project in code (release 1.3.0 stage W3-a's part library, lib.py, and one script a craft, kept with the stage's notes); 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)
Where the map uses it. NORAD 39197 (IRIS), by id; public #1090. Sun-pointing: built to the app's axes, the aperture and the cells on +Y, the wings along X
Licence note. The shape is this project's, under this repository's licence, built from published numbers (facts). The pictures it was compared with are NASA's (public domain) and figures 7 and 8 of De Pontieu et al. 2014 (CC BY 4.0); none is in the file.
