About this model
TRACERS 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 6,976 triangles in a 69 kB glTF file, and is 3.0 m across at full scale.
On Space Radar’s live map it is drawn for 2 catalogued objects, each where its published orbit puts it now. Open it on the map.

Miles et al. 2025, The TRACERS Mission, Space Sci. Rev. 221:61 (pmc.ncbi.nlm.nih.gov/articles/PMC12204947), OPENED 2026-10-20: 'Solar arrays are positioned on each of the 8 side panels and -Z decks'; 'The MSC, MAG, and MAGIC sensors are accommodated on 70 cm fixed brackets'; 'The EFI sensors are deployed on 3-m Stacer booms'; 'spin axis are aligned with the background magnetic field'. Bonnell et al. 2025, The EFI for the TRACERS Mission (pmc.ncbi.nlm.nih.gov/articles/PMC12420696): 'an 8-cm diameter graphite-coated (DAG-213) Aluminum sphere'; 'an exposed length of three (3) meters'; 'opposite sensors separated by 7 meters'. THE FOUR EFI BOOMS ARE DRAWN SHORT, illustrative: 1.25 m of their 3 m, because the app scales a model's longest side to one unit and at 7 m the 1 m body would be a dot. OURS: the body 1.06 m across the flats and 0.92 m tall (University of Iowa drawings, looked at only, and the EFI geometry), the -Z deck, the antenna patches, the cell gaps (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 the TRACERS team's published dimensions; compared with NASA's turntable (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 64870 and 64873 (TRACERS 1 and 2), by id; public #1092. The twins are one design: one file serves both. Built with the spin axis on +Z, which in the cusp is aligned with the field and so points nearly straight down
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 SpaceX's encapsulation photograph (CC0); the University of Iowa's drawings were looked at only and are in nothing.
