About this model
XRISM is one of the 203 3D models Space Radar made itself: a space telescope, generated from a public-domain picture with TRELLIS (Microsoft Research, MIT licence), then repaired, measured and completed in code.
Shape built from an artist’s render; proportions approximate. It has 13,731 triangles in a 141 kB glTF file, and is 9.2 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.

'Ground test results of the electromagnetic interference for the x-ray microcalorimeter onboard XRISM', section 2.2, ar5iv.labs.arxiv.org/html/2303.00985, OPENED 2026-10-13 (the row first took these numbers from a search result; the paper says the same): 'It has a weight of 2.3x10^3 kg and an envelope size of 7.9, 9.2, and 3.1 m respectively for the height (z), length (x), and width (y). The main body is composed of eight side panels (SP1-8) of 990x3100 mm2 in size' and 'The solar array panels are stored in SP2 and SP4 at launch and are deployed in parallel with SP3, which are oriented toward the Sun.' The XRISM Quick Reference, arxiv.org/pdf/2202.05399, opened 2026-10-13, mission table: 'Dimension 7.9 m x 9.2 m x 3.1 m'. Neither says in words that the 9.2 m (x) is the span across the paddles; it is read so because an octagon of 0.99 m panels is 2.4 m across its flats, and the generated mesh, scaled to 7.9 m of height, measured 9.4 m across its own paddles. NOT CITED: a paddle's 3.04 x 2.65 m and its three panels, from the renders and the generated mesh (read 2026-10-13)
How it was made
Generated from a public-domain picture with TRELLIS (Microsoft Research, MIT licence), then repaired, measured and completed in code. 3D model: generated from NASA Goddard renders of XRISM with TRELLIS (Microsoft Research, MIT), repaired and coloured by Space Radar.
The full record
github.com/microsoft/TRELLIS — generated on 2026-10-13 by the TRELLIS image-to-3D model (image-large weights, through the Hugging Face Space trellis-community/TRELLIS, its multi-image mode, two pictures, stochastic, seed 0) from the two NASA renders named first under `references`; the two solar paddles are not the generator's: they were built in code
Where the map uses it. NORAD 57800 (XRISM), on the layer of bright satellites: JAXA and NASA's X-ray spectroscopy telescope. It was the generic space telescope, a white drum (scene/models.js `space-telescope`), which is still what is drawn while this file is on its way; public #968. Hitomi (41337) does not wear it: it has a file of its own on this body, row `hitomi`: it has a file of its own on this body, row `hitomi`: it has a file of its own on this body, row `hitomi`: it has a file of its own on this body, row `hitomi`
Licence note. Public domain (the NASA Goddard renders it was generated from); MIT (TRELLIS, code and weights, whose licence makes no claim on what the model outputs); the repairs, the parts built in code, the proportions and the colours are this project's, under this repository's licence
