## 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 the dimensions eoPortal and CNES publish for MicroCarb and from CNES's and Airbus DS's drawings, artwork and photographs of it (looked at, not used).

built by this project in code (the private tool model-from-images: assemble.py, from a yaml of primitives written by a script, object `microcarb`), from the cited numbers and the pictures under `references`; no image-to-3D model was used, and no published mesh of the craft (CNES publishes pictures, not a model; NASA's 3D Resources path list, 1 583 paths, read by name on 2026-11-05: none of this craft)

Source: eoPortal, 'MicroCarb', https://www.eoportal.org/satellite-missions/microcarb, OPENED 2026-11-05: 'The size of the satellite is 600 x 800 x 1000 mm'; 'The MicroCarb payload has a mass of 63 kg, a size of 600 x 800 x 400 mm'; 'a Myriade Evolutions minisatellite platform'; 'CNES intends to use for MicroCarb a solar array in storage that fits the mission needs' (NO array size). CNES, https://cnes.fr/en/news/microcarb-innovative-mission-survey-co2-orbit, OPENED 2026-11-05. PAGES DISAGREE on the mass: eoPortal says about 190 kg, 175 kg and about 160 kg in three places, CNES 180 kg; the mass is not in the mesh. ESTIMATED: THE ARRAY (two panels of 0.85 m by 0.6 m, a 0.07 m hinge gap, a 0.26 m by 0.13 m notch on the outer panel), scaled from the stowed plate in CNES's figure 12, the aspect of the panels in CNES's artwork and the 200 W the page states; the three artworks do not agree on the notch's side or the array's height. The platform's 0.8 m by 0.6 m footprint and its 0.56 m depth (1.0 m less the payload's 0.4 m and the ring's 0.04 m); the PAS610 ring's 0.58 m; the oval baffle (mouth 0.52 m by 0.34 m, held within the payload's height); every small part.
