Live Earth-orbiting public objects are loaded through the local server and propagated in the browser.
Data sources
Public inputs, clear limits.
The tracker uses public catalog data and local assets. It is an investigative and educational tool, not an authoritative sensor network.
Investigation checks use SATCAT metadata for cross-catalog comparison, launch dates, and decay records.
Earth, planet textures, country GeoJSON, and visual reference layers are bundled locally for reliable rendering.
The Visuals page uses official NASA Eyes iframe app URLs for Solar System, Earth, and Exoplanets. NASA Live and Spot the Station are linked out because their pages block external framing.
Near-Earth asteroid close approaches come from the JPL CNEOS CAD API, with trajectory context from JPL SBDB orbit elements cached by the local server.
The public daily brief combines CelesTrak Earth-orbit records with NASA/JPL near-Earth-object context and explains candidate signals with explicit source limits.
The UAP Files page links to official public sources such as the PURSUE release portal, AARO imagery, National Archives UAP records, NASA UAP study material, and ODNI/DoD public reports. It does not host classified or leaked material.
538 editorial blog posts including 535 UAP-tagged analyses across 25 sub-topics — PURSUE Release 01/02 case deep-dives, FBI 62-HQ-83894 files, international historical cases, researcher profiles, AARO/UAPTF institutional analysis, nuclear-facility incursions, and contemporary news. All hedged for evidentiary care, source-attributed, and accessible at /blog.html.
Blog hero imagery is fetched live from images-api.nasa.gov using per-topic queries. Each post is matched to a thematically relevant NASA image (Apollo, Artemis, ISS, Mars, Hubble, Webb, aviation archives) with category-based fallbacks for topics outside NASA's collection.
Daily space-news posts are auto-generated by the SkyLens editorial automation 3× per day (07:00 / 13:00 / 23:00 CET) drawing on live CelesTrak satellite catalog, NASA/JPL asteroid feed, and Spaceflight News API trending stories. The schedule survives restarts via persistent state in .cache/blog-schedule.json.
Limitations
- TLE-derived positions are estimates and become less reliable as epochs age.
- Visual satellite dots are screen-scaled and do not represent physical object size.
- Asteroid trajectory arcs are compressed visualizations from public osculating elements; use JPL SBDB or Horizons for precision ephemerides.
- Public catalog anomalies are leads only and require independent validation.
