After ground controllers lost all ability to command DMSP 19 in February of this year, the US Air Force has finally admitted that it has had no success in recovering command of the satellite. An investigation found that power failure with the command and control system resulted in commands being unable to reach the command processor. Both the A and B side of the command and control subsystem failed. The satellite is in a stable orbit and is still passively transmitting imagery and data. The spacecraft had been built by Lockheed Martin Space Systems and was designed to last a minimum of five years.
