Solar activity
LOADINGHow strongly the Sun is flaring right now. X-ray brightness (GOES satellites) sets a flare’s class: C mild, M medium, X extreme. Below it, the 0-9 Kp index with NOAA’s 3-day forecast. Sources: NOAA SWPC / GOES.

Orbital regimes
LIVETurn each orbital shell on or off: Low Earth (LEO), Medium Earth (MEO), Geostationary (GEO), and Molniya. Hiding one doesn’t slow the scene down.

Conjunction watch
LOADINGPairs of tracked objects passing within 25 km of each other, screened on the graphics card twice a second. Screening only: this is a Keplerian model with J2 drift and no uncertainty estimate, so a distance here is illustrative, never an operational close-approach figure.

Sky over you
LOADINGThe next three hours of overhead traffic for one ground site, marched forward on the graphics card for every object in the catalogue at once. A pass is listed once it clears 10° above the horizon. Same model as the rest of the engine, Keplerian with J2 drift, so times drift too: the figure below is the engine measuring its own error against the live ISS fix.

About the engine
50,000 satellites, spread across four real orbital shells (LEO, MEO, GEO, Molniya), animated frame-by-frame straight on the graphics card; no game engine or 3D framework underneath, built from scratch in Rust, compiled to WebAssembly and rendered through WebGPU. It’s a stylised picture of Earth’s orbit, not a live tracker of real satellite positions, but the NASA data streaming around it is genuinely live.

NOAA scales

Geomagnetic storm · Dst
LOADINGHow deep the current geomagnetic storm goes. The Dst index measures how far a storm has dented Earth’s magnetic field: near 0 nT is quiet, below −50 nT a storm, below −100 nT an intense one. Source: NOAA SWPC / Kyoto.
