# SpaceTech7 image credits

- `earth-horizon.jpg` - NASA, ISS Expedition 71, July 16, 2024. [Noctilucent clouds below Earth's horizon, iss071e364425](https://images.nasa.gov/details/iss071e364425). Illustrative space imagery; no NASA endorsement is implied.
- `orbital-scene-mounted.jpg` - a direct capture of SpaceTech7's original Three.js spacecraft concept with an Earth-tracking antenna, Earth shader and cinematic framing, refreshed October 10, 2026. Source for the prebuilt orbital-scene-mounted.webp hero preview. Earth textures are credited below.
- `earth-day.jpg` - [NASA Earth Observatory, Blue Marble](https://visibleearth.nasa.gov/images/57730/the-blue-marble-land-surface-ocean-color-and-sea-ice). [2048 px texture](https://eoimages.gsfc.nasa.gov/images/imagerecords/57000/57730/land_ocean_ice_2048.jpg).
- `earth-night.png`, `earth-clouds.png`, `earth-water.jpg` - Earth lights, clouds, and water mask distributed with the [Three.js planet example textures](https://github.com/mrdoob/three.js/tree/master/examples/textures/planets). Used as illustrative Earth surface data.
- `engineering-assembly.webp` - archived concept asset generated for SpaceTech7 using the built-in imagegen tool. Replaced by the orbital scene; it is no longer displayed. Prompt and provenance: `next-app/docs/ASSETS.md`.
- `data-infrastructure.jpg` is the renamed copy of `data-infrastructure-racks.jpg` credited below.

## Optimized orbital assets

- orbital/earth-*-desktop.*.webp and orbital/earth-*-mobile.*.webp are compressed derivatives of the credited Earth textures above. Day and night maps retain 2048 px on desktop and use 1024 px on mobile. The 512 px cloud mask includes the original alpha contribution in linear color; the 512 px water mask preserves the sampled red channel.
- orbital/orbital-room.*.exr contains prefiltered room lighting generated from the installed Three.js RoomEnvironment at 128 px per cube face, using the same 0.03 blur as the original live calculation. The spacecraft still uses the original materials, directional lights, and animations.
- Generate these assets with scripts/bake-orbital-assets.mjs; content hashes in each filename allow immutable caching. The manifest is data/orbital-assets.json.
