SeaLagom sky: 3D model credits
The models of the sky (frontend/public/models/), made by tools/sky/build_models.py on 31 October 2026.
Format: file | object on the sky | model | by | terms | source

voyager.glb | Voyager 1 and Voyager 2 | Voyager Probe (A) | NASA/Christopher R. Meaney | NASA 3D Resources, used under the NASA Images and Media Usage Guidelines (https://www.nasa.gov/nasa-brand-center/images-and-media/): NASA is named as the source, the model carries no NASA insignia or logo, and its use does not mean that NASA endorses SeaLagom or anything SeaLagom offers | https://science.nasa.gov/3d-resources/voyager-probe-a/
  What we changed: the Draco compression decoded, the faces reduced from 29,911 to about 12,000, the size set in metres (the high gain antenna 3.66 m across), the golden record given a gold colour, the file written without compression. One model stands for both Voyagers, which were built the same.

roadster.glb | Tesla Roadster (the car launched on the first Falcon Heavy, 6 February 2018) | our own simple shape of the 2008 Roadster with a figure in the driver's seat, from its published size (3.95 m long, 1.85 m wide, 1.13 m high, wheelbase 2.35 m) | SeaLagom | our own work | tools/sky/build_models.py
  No other model was used. Tesla and SpaceX are named only to say which object this is; neither made or checked this shape, and neither endorses SeaLagom.

starlink.glb | Starlink satellites | our own simple shape of a Starlink V2 Mini: a flat body and two solar wings, about 28 m across, sizes approximate | SeaLagom | our own work | tools/sky/build_models.py
  No other model was used. SpaceX did not make or check this shape and does not endorse SeaLagom. Older Starlink satellites have a single solar wing; on the sky every Starlink is drawn as a V2 Mini, its flat side to the Earth and along its track (drawn, not measured), and only when it is close enough on the screen for its real size to show.

Why our own shapes for the car and the satellite (looked at on 31 October 2026): the free models found in a search were on Sketchfab (CC BY, downloads only with an account, which we do not create for this), on 3D printing sites, or on sites that state no licence we could check, and the free "Tesla Roadster" models found show the 2020 prototype, not the 2008 car that flew.
