About this model
Hayabusa2 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 13,178 triangles in a 86 kB glTF file, and is 6.0 m across at full scale.
On Space Radar’s live map it is drawn where the craft is today. Open it on the map.

eoPortal, 'Hayabusa-2', eoportal.org/satellite-missions/hayabusa-2, OPENED 2026-10-20: 'The Hayabusa-2 spacecraft has a stowed size of 1.6 m x 1 m x 1.25 m (height). With the solar panels deployed, the 600 kg satellite as a width of 6 m.'; 'Size: 1.6 m×1.0 m×1.4 m(height) box structure with two fixed SAPs'; 'Hayabusa-2 uses two planar HGAs'; 'IES (Ion Engine System): Xe microwave discharge ion engine system; Maximum thrust 28 mN, Isp=2800 s; 4 thruster heads on gimballed stage'; 'RCS (Reaction Control System): Bi-propellant hydrazine system, 20 N thruster x 12'.

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, DLR renders (CC BY 2.0) and a Planetary Society diagram (CC BY 3.0).
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: JAXA publishes no model of the probe under terms that allow an altered derivative, and NASA has none (searched 2026-10-20); DLR's renders (CC BY 2.0) and The Planetary Society's diagram (CC BY 3.0) were looked at for the layout and are not in the file; JAXA's 1:20 model (photograph CC BY-SA 4.0) and JAXA's labelled views were looked at only. NO JAXA PICTURE OR MODEL IS IN THE FILE
Where the map uses it. JPL Horizons -37, Hayabusa2 (data/sample.js `deep-hayabusa2`), JAXA's sample-return probe, back from Ryugu in 2020 and bound for 1998 KY26: a gold box with two flat antennas on top, two three-panel wings on ladders, the ion engines on one face and the sampler horn below. It was the generic probe; public #1087
Licence note. CC BY 2.0 (DLR's renders) and CC BY 3.0 (The Planetary Society's diagram), which the layout was read off: looked at, with credit; nothing of them is in the file. The shape is this project's, under this repository's licence, built from published numbers (facts). JAXA's 1:20 model (photograph CC BY-SA 4.0) was looked at only. NO JAXA PICTURE OR MODEL IS IN THE FILE. NO LOGO AND NO LETTERING is on the mesh.
