About this model
SCISAT-1 is one of the 203 3D models Space Radar made itself: a satellite, 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 12,840 triangles in a 68 kB glTF file, and is 1.1 m across at full scale.
On Space Radar’s live map it is drawn for the object with NORAD catalogue number 27858, where its published orbit puts it now. Open it on the map.

eoPortal, eoportal.org/satellite-missions/scisat-1, OPENED 2026-10-26: 'SciSat-1/ACE is a relatively small satellite with a diameter of 112 cm, a height of 104 cm and a total mass of 150kg.'; 'uses a circular instrument/component aluminium mounting plate (1.12 m in diameter) as the main structure of the platform'; 'The spacecraft is always in a sun-pointing configuration. S/C power (75 W orbital average, triple junction solar cells ...) is generated by a single body-mounted solar panel.' OURS: the instruments' sizes and places inside the 104 cm height, read off the labelled drawing.
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 (no free picture of the craft).
The full record
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's 3D Resources, 1 583 paths read 2026-10-26, and NASA Science's resources have none of this craft; the agency pages were searched, and no agency model of it under usable terms was found); no CSA or Bristol Aerospace picture is in the file: eoPortal's labelled drawing (Figure 10) and the artist's views (Figures 12 to 14) were looked at only
Where the map uses it. NORAD 27858, SCISAT 1, in the live saved data of 2026-10-12: Canada's atmospheric-chemistry minisatellite (ACE), flying since 2003: a 1.12 m round plate of solar cells with the FTS spectrometer, MAESTRO, the star tracker, a round white cryo-radiator and an antenna mast on its back. It wore the shape of its class; public #1106
Licence note. This project's own shape, under this repository's licence, built from published numbers (facts). NO FREE PICTURE OF THE CRAFT WAS FOUND: the CSA's pictures are for non-commercial use, were looked at only (named under references) and nothing of them is in the file. NO LOGO AND NO LETTERING is on the mesh.
