## 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 photographs of museum models (Armael, CC0; Museum of Cosmonautics, CC0; Stolbovsky, CC BY 4.0).

built by this project in code (release 1.4.0 stage r14-m8's scripts, one a craft, on release 1.3.0's part library, kept with the stage's notes), 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, science.nasa.gov/3d-resources, 377 entries, and NASA Science's 3D-type resources have none of these craft; Lavochkin publishes none; read 2026-10-26)

## Dimensions

- Sphere diameter: 1.2 m
- Braking cone: 2.9 m
- Lander mass: 1210 kg
- Capsule mass: 358 kg

Source: Wikipedia, 'Mars 3', https://en.wikipedia.org/wiki/Mars_3, OPENED 2026-10-26: 'It consisted of a spherical 1.2 m diameter landing capsule, a 2.9 m diameter conical aerodynamic braking shield, a parachute system and retro-rockets'; 'The landing capsule had four triangular petals which would open after landing, righting the spacecraft and exposing the instrumentation'; 'Four aerials protruded from the top of the sphere'; 'two television cameras with a 360 degree view'; the lander mass 1,210 kg and the capsule's 358 kg. The 'PrOP-M' page names a 4.5 kg ski rover carried and 'never deployed'. OURS: every other size, read off the photographs of the 1:1 mock-up with the 1.2 m as the ruler (the petals 0.98 m long and 0.96 m wide at the hinge, opened 62 degrees below the horizontal; the belt; the aerials 1.15 m; the instrument box 0.32 by 0.40 m; the camera tubes), about 10 to 15 percent. THE PETALS' ANGLE is OURS (the mock-ups show them open; how far they opened on Mars is not known)
