## 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 of Insight-HXMT and pictures by the Institute of High Energy Physics, Chinese Academy of Sciences (CC BY 4.0, 'HXMT rendering.jpg') and Zhang et al. (arXiv 2311.06529, CC BY 4.0).

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 (CAS and IHEP publish none; NASA's 3D Resources has none of this craft; read 2026-11-03)

## Dimensions

- Payload: 1.9 × 1.6 × 1 m
- Height: 2.84 m
- He module diameter: 0.19 m
- He modules: 18
- Wing: 3.5 × 1.75 m
- Span: 10.1 m

Source: CITED: total mass 'about 2500 kg', 'two cabins, the payload cabin and the platform cabin. The payload cabin is on the top of the satellite, in which all the telescopes are installed. The telescopes are all aligned to one direction... There is a sun-shielding board on one side of the satellite' (Zhang et al., 'Overview to the Hard X-ray Modulation Telescope (Insight-HXMT) Satellite', https://arxiv.org/abs/1910.09613, Sect. 2.1, OPENED 2026-11-03); 18 HE phoswich modules 'with a diameter of 19 cm', 15 collimators of 1.1 x 5.7 deg (at 0, +60, -60 deg), two of 5.7 x 5.7 deg and one blind, three ME boxes and three LE boxes (same paper, Sect. 2.2 and Table 2); an ME box with an 'integral radiant cooling plate', a 'screwed radiant cooling plate', mid and side collimators and a cube mirror (same paper, Fig. 6); 'the two star sensors installed on the main support structure' and 'a sun shield... always faces the sun' (https://arxiv.org/abs/2311.06529, Sect. 1 and 2, OPENED 2026-11-03); 'Payloads onboard HXMT, Size: 1900 x 1600 x 1000 mm' (slide 5, Zhang Shu, 'Introduction on HXMT Project...', IACHEC, the file linked under references, OPENED 2026-11-03: read as the payload cabin's envelope); 'Dimensions 2.0 x 2.0 x 2.8 m' and 'Launch mass 2,800 kg' (the Wikipedia article 'Hard X-ray Modulation Telescope', infobox, OPENED 2026-11-03: it names no source, and is read as the craft as launched, 2.0 m across the platform and 2.8 m tall with the payload and its shield; the two masses differ and the paper's 2500 kg is the one cited); 'based on the JianBing 3 imagery reconnaissance satellite series platform' (same article). ESTIMATED, NOT CITED, READ OFF THE PICTURES: the platform's 1.7 m height (from IHEP's rendering and the CAD pictures); THE SOLAR ARRAY: two wings of three panels, each panel 1.17 x 1.75 m (a wing 3.5 m long and 10.1 m tip to tip, standing 0.55 m off the platform) is an ESTIMATE against the platform's 2.0 m width and the 19 cm modules, because NO PAGE OPENED GIVES THE ARRAY'S SIZE (the rendering shows three panels a wing; each panel's 2 x 3 sub-rectangles are read from it); the sun shield's 1.8 x 1.04 m; the heights of the instruments above the deck (0.45 to 0.5 m); the LE and ME boxes' sizes; the deck's twelve sides and the packing radii of the HE modules (six at 0.30 m and twelve at 0.58 m from the middle: read from arXiv 2311.06529 Fig. 6 and the CAD); every piece of hardware on the platform's faces, and the whole of the -X and back faces, which no picture opened shows (put there by judgement).
