 Radio ham finds signal from 'dead' NASA satellite

*Scott Tilley VE7TIL / VA7LF* discovered a signal from the IMAGE satellite
that NASA lost contact with in 2005

Arstechnica reports earlier this week, an amateur radio astronomer named
Scott Tilley decided to have a look for the presence of secret military
satellites.
It's something he apparently does semi-regularly, and in this case his
search was inspired by the Zuma satellite, a secret US government payload
that was reportedly lost on its way to space.

Most accounts have suggested that Zuma failed to make it to orbit, but the
secrecy of the mission (we've got no clear idea what Zuma even was) means
that everything about its fate is unclear. Tilley could either find a hint
that Zuma is up there—or stumble across some other hardware put into space
by other countries.

Instead, he found an undead NASA mission.

Given the clear indication of a radio signal, Tilley matched its orbit to a
NASA satellite called IMAGE.
