## 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 DLR's photograph of a model of Sentinel-2 (DLR German Aerospace Center, CC BY 2.0).

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 (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 pictures and models were NOT used: ESA's terms forbid derivative works)

Total array area of 7.1 m 2 .'; 'SADM (Solar Array Drive Mechanism) for array articulation.'; 'The telescope features a TMA (Three Mirror Anastigmat) design with a pupil diameter of 150 mm'; 'The mechanical structure of MSI instrument holds the 3 mirrors, the beam splitter device, the 2 focal planes and 3 stellar sensors. It is furthermore mounted on the satellite through 3 bolted bipods. This main structure has a size of 1.47 m long x 0.93 m wide x 0.62 m high with a mass of only 44 kg.'; 'The satellite is controlled in 3-axes via high-rate multi-head star trackers, mounted on the camera structure'; 'X-band payload data downlink at 560 Mbit/s'; 'LCT (Laser Communication Terminal) link is provided via EDRS (European Data Relay Satellite)'; '10:30 hours LTDN (Local Time at Descending Node)'. eoPortal's table of the three Sentinels (on its Sentinel-1 page, opened the same day) gives another size: '1140 kg 3.0 m x 1.7 m x 2.2 m 1.7 kW (EOL)'; ESA's is built. DERIVED: 7.1 m2 as three panels of 1.25 x 1.9 m. READ OFF THE PHOTOGRAPHS of two models: a gold box with the instrument at one end, deeper than the bus on the Earth side, with a wide dark opening in a raised frame and a dark band where it meets the bus; one wing of three panels from the middle of a side, its long side square to the body; a white antenna and small boxes on the Earth face; a dark launch ring at the other end. OURS: the split of the 3.4 m into a 2.0 m bus and a 1.4 m instrument; the bus's 1.9 m depth; the opening's size; the star trackers', antennas', laser terminal's and radiators' places and sizes, the instrument's radiator on its sky face among them. NOT FOUND in words: which of the body's sides is the Earth's, and which way its length lies to the track.
