AO-40 Telemetry Transmissions Stop

Development Team Investigating



Early Wednesday, December 13th, telemetry transmissions from AO-40 stopped while work on the 400 N propulsion system was in progress. An investigation by the AO-40 development team has begun. They are now waiting for certain on-board software events to occur on Saturday afternoon, December 16th. These are programmed to start a spacecraft emergency routine called 'command-assist' which attempts to re-establish communications. This offers the best chance of recovering evidence of the incident which made the telemetry transmissions stop.



When more information becomes available, we will pass it along.
