## How it was made

Generated from a public-domain picture with TRELLIS (Microsoft Research, MIT licence), then repaired, measured and completed in code. 3D model: generated from a NASA photograph with TRELLIS (Microsoft Research, MIT), cleaned and coloured by Space Radar.

https://github.com/microsoft/TRELLIS — generated on 2026-10-12 by the TRELLIS image-to-3D model (image-large weights, through the Hugging Face Space trellis-community/TRELLIS, one picture, seed 0) from the NASA photograph named first under `references`

## Dimensions

- Length: 6.39 m
- Diameter: 3.07 m
- Array: 3.7 m

Source: length and diameter: https://en.wikipedia.org/wiki/Cygnus_(spacecraft) infobox, Enhanced variant, read 2026-10-12 (the page cites Spaceflight101, which answered 404 that day, not a Northrop Grumman sheet). Two fixed arrays: Northrop Grumman's Cygnus fact sheet DS-57a, https://www.northropgrumman.com/wp-content/uploads/Cygnus-Fact-Sheet.pdf, read 2026-10-12: '2 fixed wing UltraFlex solar arrays'; it prints no dimensions. Array width: NOT READ ON A PRIMARY PAGE. 3.7 m is the figure scene/models.js has carried since spec 0027; a web search on 2026-10-12 reported a NASA blog post of 2015-12-06 as saying each circular array is more than 12 feet (3.66 m) across, and that post's address (blogs.nasa.gov/northrop-grumman/2015/12/06/cygnus-to-deploy-solar-arrays-later-today) now redirects to NASA's blog index, so nobody here has read it. It is the least-sourced number in this row
