“Maidanovich told the program that specialists in the ADF’s Intelligence Center uncovered ‘a newly deployed group of space satellites’ that were designed to collect signals intelligence (SIGINT) from Russian telecommunications and other electronic systems. However, the satellites had been disguised to appear and behave like ‘space junk’, he said. By ‘space junk’, Maidanovich was referring to rocket stages, old and defunct communications satellites, and various other fragments of manmade devices that have ended up in outer space since the 1950s and are endlessly orbiting the Earth.”
