Hello,

I don't possess any "inside information" on what the cause was of ARISSat-1 not to be heard, however I have a theory. We know that Packet transmission's ended and began soon after the posted times for ARISSat to be powered on/off, this action was done because they agreed that the satellite "woke up". The power on sequence for ARISSat-1 is visual, meaning that if their was a battery failure they would not have seen the satellite power up. If we believe that this occurred a possible reason for not hearing the satellite was that it was connected to the wrong antenna, and seeing the coax in this area it is conceivable that this might be the cause. I know we will learn what actually occurred, at some point, it's our priority not theirs, perhaps we can have a contest, "pick the cause" and the winner can win a good night's sleep in a motel of their choice, satellite equipment not permitted.
