## 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 and a NASA render of XMM-Newton (NASA's Scientific Visualization Studio, public domain).

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 on GitHub, 1 583 paths read 2026-10-13, has none of this craft; the survey of 2026-10-13 found no agency model of it under usable terms; ESA's own model at scifleet.esa.int was NOT used: ESA's terms forbid derivative works)

The total length of XMM-Newton is 10 m, and its solar arrays give the satellite a 16 m span.'; 'The solar array has two wings, each with three rigid 1.94 m x 1.81 m panels, giving a total area of 21 m 2'; 'The two wings are body-fixed and have a Sun incidence angle variation around normal of up to 28º.'; 'Due to its length of 6.80 m, the Telescope Tube is physically composed of two halves: the upper and lower tubes.'; 'Mirror diameter and thickness Outermost:700 mm / 1.07 mm, Innermost: 306 mm / 0.47 mm'; 'Reflective surface Gold (250 nm layer)'; 'The SVM,carrying the spacecraft subsystems, the two solar-array wings, the TSS (Telescope Sun Shield) and the two S-band antennae.'; 'The SVM ... is also fully blanketed with the exception of panel radiators. On the Sun-side they are covered by mirror solar reflectors, while those on the anti-sun side of the satellite are painted white.'; 'The EPIC and RGS instruments are fitted with radiators, to passively cool the CCDs'; 'Together with the black lining of its internal surface'. DERIVED: 10 m as 1.5 m of service module and doors, 6.8 m of tube, 1.7 m of focal plane; the wings' roots 2.18 m from the axis, so that three 1.94 m panels a side reach 16 m. READ OFF NASA'S RENDER: the eight-sided service module, the round aperture with three mirrors and the smaller optical monitor, the three open doors, the sun shield standing on one side, the black blankets. OURS: the service module's 3.2 m and the tube's 2.1 m across (no page opened gives either), every shape at the focal-plane end (the render does not show it), the doors' places.
