## 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/JPL artist's concept of Seasat with TRELLIS (Microsoft Research, MIT), repaired and coloured by Space Radar.

https://github.com/microsoft/TRELLIS — generated on 2026-10-13 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/JPL artist's concept named first under `references`; only the trunk is the generator's: the wings, the radar antenna, the stick antennas, the dishes and the booms were built in code

## Dimensions

- Length: 21 m
- Diameter: 1.5 m
- Sar length: 10.74 m
- Sar width: 2.16 m
- Solar cells: 14.5 m²

Source: https://www.eoportal.org/satellite-missions/seasat, read 2026-10-13: 'S/C size: 21 m length, 1.5 m diameter'; 'the SAR antenna, a 2.1 m x 10.7 m planar array deployed perpendicular to the satellite body' and '1024-element phased array antenna of size 10.74 m x 2.16 m'; the solar panels 'made up an area of 14.5 m2 of solar cells', 'two wings mounted on either side of the aft rack'. NOT CITED, placed by eye from the two artist's concepts: each wing's 4.85 x 1.5 m (the cited area split in two), where the radar antenna hangs and its 20 degree tilt, and the size and place of every stick antenna, dish and boom
