How the Spacecraft Still Tracked screensaver works
The saver reads the source described above and draws it on a canvas — no account, no tracking.
The satellites NASA's Satellite Situation Center can currently compute a position for, key-less. The catalogue reaches back to the 1960s and is mostly dead missions, so this keeps only the ones whose coverage runs past today and ranks them by how long they have been on station.
It refreshes on a schedule, so what you see stays current.
Colours and any options can be changed in settings; nothing is stored beyond your own browser.
