Satellites watch our planet all the time, sometimes for top-secret military reasons, sometimes for reasons as quotidian as making a cellphone call possible.
Satellite watchers like Kevin Fetter and Ted Molczan watch back. Molczan told us about his extreme hobby today on the show.
Now Fetter shares the video above. The first images are of a satellite crossing the moon. The second image captures the incredibly bright reflection, or flare, from a particular type of satellite turned at an exact angle. The third set shows trios of Naval Ocean Surveillance System satellites moving across the night sky. If you like these, check out the rest on Fetter's personal site.
