Space Domain Analysis (what's over you right now)
Orbital data: CelesTrak GP data, originally from USSPACECOM via Space-Track.org. A copy is saved with the site. Once it is more than a day old your browser fetches fresh data from CelesTrak and keeps it for six hours, and a small bundled copy is the last fallback
Propagation: satellite.js 6.0.2 (SGP4), MIT License, self-hosted
Sun position, sky map and globe: Velox's own code. Your location is used in your browser only and is not sent anywhere.
3D rendering: three.js r186, © 2010–2026 three.js authors, MIT License, self-hosted
Earth textures: NASA Earth Observatory / GSFC. Day: "The Blue Marble: Land Surface, Ocean Color and Sea Ice" (Reto Stöckli, Robert Simmon, MODIS, 2002). Night: "Earth's City Lights" (DMSP data via NOAA NGDC, 2000). Public domain NASA imagery, as redistributed in the three-globe package (MIT), downscaled by Velox. No endorsement implied.
Place search: GeoNames populated places of 1,000 people or more, CC BY 4.0, as packaged in all-the-cities 3.1.0 (© 2018 Nabil Ashraf, MIT License). Reformatted by Velox into small files and searched in your browser.
First place shown: the main city of your browser's time zone, from the IANA time zone database (public domain) and the GeoNames places above. US Eastern time opens on Reston, VA.
Hub cities and the populated-land map (packet journey, race, ride along): city coordinates and populated cells from GeoNames, CC BY 4.0, keyed by each city's IATA airport code.
Laser mesh, coverage map, race and GPS walkthrough: Velox's own models over the CelesTrak data, described on the page. Starlink does not publish its laser links, so the mesh is a model.
