About this model
Centaur D is one of the 203 3D models Space Radar made itself: a rocket stage, 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 19,216 triangles in a 118 kB glTF file, and is 9.6 m across at full scale.
On Space Radar’s live map it is drawn for the object with NORAD catalogue number 694, where its published orbit puts it now. Open it on the map.

NASA NTRS 19750004937, 'Titan IIIE/Centaur D-1T Systems Summary' (Convair/Martin Marietta, 1973), as Wikipedia, 'Centaur (rocket stage)' quotes it, read 2026-10-26: Centaur D-1T 'Diameter 10 ft', 'Length 31.5 ft', two RL10A-3-3, four 6 lbf attitude thrusters. The Centaur D of the Atlas-Centaur is the same 10 ft tank (the 1963 AC-2 stage is shorter and is drawn with this file; NOT CITED: its exact length). OURS: the bells (1.0 m exit, 1.55 m long, read off GRC-1964-C-71099 against the 3.05 m tank), the doubler tabs, the forward truss and boxes (read 2026-10-26)
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; compared with NASA's and SDASM's photographs of Centaur D (public domain, no restrictions).
The full record
built by this project in code (tools/stage-builder/, release 1.4.0 stage r14-m1: stagelib.py and one function a stage in stages.py); no image-to-3D model was used and no published mesh: none of NASA 3D Resources' 1 583 paths is this stage and a web search found no agency or operator model of it (read 2026-10-26)
Where the map uses it. catalogue name ATLAS CENTAUR R/B (klass rocket), which also reaches ATLAS CENTAUR R/B(2), and NORAD 694 (ATLAS CENTAUR 2, 1963, the stage itself catalogued as a payload): the Centaur D of Atlas-Centaur, 39 in orbit; public #1166. ATLAS 5 CENTAUR R/B is the Common Centaur and has its own file
