Listening to the time-music of space

"He watched the sky, listening to the time-music of the quasars"
J.G. Ballard

The long-lost twin of the radio station Radio Astronomy has been found.

Space Weather links to the Air Force Space Surveillance Radar, which transmits a 216.98 MHz signal into the heavens 24 hours a day, 7 days a week. Meteors, satellites and spacecraft passing overhead reflect those signals back down to Earth. The radar's primary antenna is located near Lake Kickapoo, Texas. A few hundred miles away in Roswell, New Mexico, radio engineer and long-time associate Stan Nelson picks up the echos using a yagi antenna on his roof. When a meteor or satellite passes over the facility, there is an whistling echo.
