## 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.

https://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

## Dimensions

- Height: 7.9 m
- Span: 9.2 m
- Width: 3.1 m

Source: 'Ground test results of the electromagnetic interference for the x-ray microcalorimeter onboard XRISM', section 2.2, https://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, https://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
