Psst! Have you ever seen a giant blue box with no windows? Near here, there used to be a building that people called the Blue Cube! It was a big, blue, windowy-less building, like a giant block that a giant kid forgot to put away.
Inside, people from the Air Force worked on controlling satellites, the things that fly around way up above the Earth. Outside, there were three big dish antennas, named Sun East, Sun West, and Sun 3. They were like giant ears listening to the sky. The station worked for fifty years, from 1960 to 2010.
