ISS position
Live coordinates from the free wheretheiss.at API (no auth; ~1 req/sec; polled on our 20-minute cron). TLEs from CelesTrak when reachable.
Live from the ISS (video)
Embedded Official NASA YouTube stream Live High-Definition Views from the International Space Station via youtube-nocookie.com (lazy-loaded). Video ID taken from NASA’s own ESRS HDEV live page. Video: NASA. Channel @NASA (UCLA_DiR1FfKNvjuUpBHmylQ). Fallback: nasa.gov/iss.
Earth & Sun right now
Earth: NOAA GOES-19 (GOES-East) full-disk GeoColor stills from cdn.star.nesdis.noaa.gov (~10 min cadence). Image: NOAA/NESDIS/STAR, GeoColor CIRA. Loaded as plain <img> (no Worker proxy).
Sun: NASA Solar Dynamics Observatory AIA 171Å latest still (sdo.gsfc.nasa.gov/assets/img/latest/). Image: NASA/SDO and the AIA science team. Educational / informational use per SDO image use.

Asteroid close approaches
NASA/JPL SBDB Close-Approach Data API. U.S. government work / public domain. Size ranges use a standard H-magnitude → diameter formula across albedos 0.05–0.25 — approximate only. Not impact warnings.
Asteroid illustration
Procedural 3D near-Earth asteroid rendered with three.js r160 (MIT License) via jsDelivr — icosahedron displaced by layered noise with carved craters. Fallback still image: NASA PIA24921 Bennu (OSIRIS-REx), PD-USGov-NASA, for reduced-motion / no-WebGL.
Starlink constellation
Orbital elements from CelesTrak GP GROUP=starlink (TLE). Cached in KV and refreshed at most every 3 hours. Positions propagated in the browser with satellite.js (MIT License) via jsDelivr. Catalog count is the real GP row count; the map draws a dense sample (thousands of dots) matching the on-page counter.
World map land outlines
Natural Earth 1:110m Land (ne_110m_land), public domain. Simplified to an inline SVG path with the same equirectangular projection as the ISS marker. Made with Natural Earth.
