About this model
JUICE is one of the 203 3D models Space Radar made itself: a deep-space probe, built in code from published dimensions and photographs, with no image-to-3D generator and no one else’s mesh.
Shape built from published dimensions and pictures; details simplified. It has 8,984 triangles in a 45 kB glTF file, and is 27 m across at full scale.
On Space Radar’s live map it is drawn where the craft is today. Open it on the map.

RPWI has three additional electric 2.5-'; 'Overall, these wings are made up of ten 2.5 x 3.5 m panels (five on each side) with a total area of 85 m 2 (and a total of 23 560 solar cells ) – the largest ever built for an interplanetary spacecraft, measuring 27 m from tip to tip.'; 'via the 2.5-metre High Gain Antenna (HGA'.

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 ESA's published dimensions (no free picture of the craft).
The full record
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 Science's 3D models, 100 resources listed 2026-10-15, and NASA's 3D Resources, 1 583 paths, have none of this craft); NO ESA PICTURE OR MODEL IS IN THE FILE: ESA's published numbers were read as numbers. ESA's terms for the images on its site, read 2026-10-15 (esa.int/ESA_Multimedia/Terms_and_Conditions): 'The website of the European Space Agency (the ESA Website) provides to users an online access to space images and videos for education, editorial and/or information purposes only. All other uses (e.g. commercial ones) are excluded and require a specific licence.' The JUICE Science Operations Centre's CAD-derived model in the SPICE kernels states no licence (its documentation page, the kernels' readme and the FTP folder, read 2026-10-15): the MESH WAS NOT FETCHED; its documentation's table of component places (numbers) was used
Where the map uses it. JPL Horizons -28, JUICE (data/sample.js `deep-juice`), ESA's Jupiter Icy Moons Explorer on its way to Ganymede: a grey box with a 2.5 m dish, two cross-shaped wings of five panels, a 10.6 m magnetometer boom and a 16 m radar antenna. It was the generic probe; public #1082
Licence note. This project's own shape, under this repository's licence, built from ESA's published numbers (facts) and the component places published by the JUICE Science Operations Centre (numbers). NO FREE PICTURE OF THE FLIGHT CRAFT WAS USED: ESA's renders (CC BY-SA 3.0 IGO, share-alike) were looked at only (named under references) and nothing of them is in the file. NASA's icon of JUICE (public domain) draws an older design and was not followed. NO ESA PICTURE OR MODEL IS IN THE FILE. NO LOGO AND NO LETTERING is on the mesh.
