AO-51 is a great craft and so is the team that is continuing to ensure its 
operation to the end. You guys are incredible.

Subject: [amsat-bb] AO-51 end of mission

It is with a heavy heart I report that AO-51 has ceased transmission and is not 
responding to commands. The last telemetry data indicated that the third of six 
batteries was approaching failure to short, and observations indicate the 
voltage from three cells is insufficient to power the UHF transmitters. The IHU 
may continue to be operative.  Initial tests with the S band transmitter were 
also not positive, although more attempts are in order. We have tried leaving 
the satellite in an expected state where if voltages climb high enough, the 
435.150 transmitter may possibly be heard.

The command team will regularly attempt communications with the satellite over 
the coming months (and years). There is always the possibility that a cell will 
open and we could once again talk to our friend while illuminated. Thanks to 
all who helped fund, design, build, launch, command, and operate AO-51.  It's 7 
year mission has been extraordinary. Please support AMSAT's Fox-1 project, and 
other AMSAT projects worldwide with your time and money.

For the AO-51 Command Team,

73, Drew KO4MA
AMSAT-NA VP Operations
