## 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 eoPortal's published numbers for the SkySat C series and from pictures of it by Space Systems Loral and Skybox Imaging (looked at, not used).

built by this project in code (the private tool model-from-images: assemble.py, from a yaml of primitives, object `probe-skysat`), from the cited numbers and the pictures under `references`; no image-to-3D model was used, and no published mesh of the craft (NASA's 3D Resources carry none; Planet publishes pictures, not a model, and the pictures eoPortal reproduces are credited to Skybox Imaging, Space Systems Loral, SpaceX and ECAPS, none free to derive from, so they were looked at only)

Source: eoPortal, 'SkySat Constellation', https://www.eoportal.org/satellite-missions/skysat, OPENED 2026-11-03 (Table 3): 'Attribute Generation A Generation C Mass 83 kg 110 kg Dimensions 60 x 60 x 80 cm 60 x 60 x 95 cm Total ΔV No propulsion ~200 m/s Design life ~4 years ~6 years'; 'Each SkySat satellite is equipped with a Ritchey-Chretien Cassegrain telescope (35 cm ∅) with a focal length of 3.6 m'; 'features body-mounted solar panels'; 'The microsatellites feature an aperture cover that protects the imaging payload during launch and initial orbital operations. The cover also hosts the high-data rate antenna of the satellite'; Figure 2: SkySat-3 '~15 cm taller' and '~30 kg heavier' than SkySat-1 and -2; 'Spacecraft size (stowed configuration) 60 cm x 60 cm x 80 cm' (Table 1, the prototypes); the ST-16 star tracker '59 x 56 x 31.5 mm' (Table 2). en.wikipedia 'SkySat' (OPENED 2026-11-03) DISAGREES in two places: 'approximately 80 centimetres (31 in) long ... 220 pounds (100 kg)' (it does not say which generation; it matches eoPortal's Generation A, the prototypes) and 'The 13 SkySat-C satellites are slightly larger and heavier (with mass about 120 kg)'; this build follows eoPortal's table for the C generation (60 x 60 x 95 cm, 110 kg) because it states the generation and the three numbers together; Wikipedia's 80 cm matches the prototypes' 80 cm in eoPortal's table. NOT CITED, READ OFF THE PICTURES AND ESTIMATED against the 0.60 m deck: the aperture ring (0.52 m outer, 4 cm proud), the cover plate (0.53 m beyond the edge, 0.54 m wide), the dish (0.40 m, 5 cm deep) and its bipod (0.30 m high), the aluminium band's height (0.41 m of the 0.95 m), the chrome baffle (8 cm long), the port, the four thrusters' places and cants, the cell tiles (6 x 9 of about 8 x 10 cm on a face: the real cells are a few centimetres), the olive ring under the craft (0.46 m across) and the copper pads on the deck. Which face carries the band, and which edge the cover hinges on, is not the same on every picture; the build puts the band and the hinge on +X.
