, possibly due to a failure in the payload adapter provided by Northrop Grumman in detaching from the second stage. According to ''The Wall Street Journal'', sensors had not reported the initial failure to detach. Later on, Zuma did ultimately detach from the upper stage payload adapter, but only after it was too late and with the orbit too low to attempt a rescue of the satellite.

In the media
The U.S. government has not publicly stated if there was a failure of Zuma, and this secrecy has generated speculations on its purpose and its fate. A number of articles published by the amateur satellite tracking community stated that if the satellite was still in orbit or operating covertly, then it would likely be located visually. In the process of searching for Zuma, amateur astronomers instead found radio transmissions from IMAGE
