Sky
- Milky Way panorama: ESO/S. Brunier, CC BY 4.0. Adapted: cropped, rotated, re-exposed, and re-rendered as a daylight plate for the light theme. The masthead band is a crop of the galactic core from the same panorama, graded (curves, vibrance, smart sharpen) with PhotoCraft.
- Small rocks and dust along the route are procedural, generated in the browser; no third-party models.
Small bodies
- 101955 Bennu: OSIRIS-REx SPC global shape model v42 (3.17 m), NASA/Goddard/University of Arizona, PDS Small Bodies Node.
- 433 Eros: Gaskell Eros shape model from NEAR Shoemaker MSI images (R. Gaskell), NASA/JHUAPL, PDS Small Bodies Node.
- 162173 Ryugu: Hayabusa2 SfM shape model (SHAPE_SFM_200k_v20180804), Watanabe et al. 2019, Science 364, 268; JAXA DARTS.
- 25143 Itokawa: Gaskell Itokawa shape model from Hayabusa AMICA images (R. Gaskell), JAXA, PDS Small Bodies Node / JAXA DARTS.
- 951 Gaspra: global shape from P. Stooke’s radius model derived from Galileo SSI images (Stooke 1997, Earth, Moon and Planets 75, 53; after Thomas et al. 1994), PDS Small Bodies Node, doi:10.26033/yt84-5y91. The model fixes the overall shape only; small craters and grooves at the scale of the engraving are illustrative, not mapped features.
- Decimated, locally levelled under each word, engraved and baked in Blender (tools/celestial in the repository). Silhouettes are the missions'; boulder detail is added.
