Imagery and visual assets
| Asset | Source | Credit / licence |
|---|---|---|
| Planet texture maps used in the solar-system dots | NASA/JPL planetary maps | NASA/JPL imagery. NASA content is generally not subject to copyright in the United States; used with credit. |
| Earth frames on the Earth page | NASA DSCOVR EPIC | NASA/EPIC team. Natural-colour imagery and timestamps via the public EPIC API. |
| Mars rover photography | NASA Image and Video Library | NASA/JPL-Caltech and mission teams. Images are loaded from NASA’s public archive and linked back to their source records. |
| Saturn portrait and moon data | NASA Cassini “Saturn in Color”; JPL satellite orbits | NASA/JPL-Caltech. Moon catalogue and orbital elements from NASA/JPL. |
| Solar-system, Proxima, and interface graphics | Original CSS, SVG, and HTML by deepinthe.space | Original work. Inspired by public astronomical data and the visual language of planetaria. |
| Icons (theme, menu, orbit marks) | Original inline SVG | No third-party icon set is bundled. |
Code and open-source software
The site is currently built with plain HTML, CSS, and vanilla JavaScript. No third-party JavaScript framework, analytics library, or icon package is bundled. The only external code requests are public NASA data APIs used by the Earth and Mars pages.
- Typography: the system UI font stack (no web font files are downloaded).
- Build and hosting: static files served by Cloudflare Pages.
- Contact storage: Cloudflare Pages Functions and D1, using Cloudflare’s runtime APIs.
- Development assistance: portions of the codebase were created and edited with OpenAI Codex. All content is reviewed and owned by the operator.
If a third-party library is added later, its name, version, licence, and repository link will be listed here.
