[amsat-bb] Re: AO-27 possible failure

[Robert McGwier]

AO-27 computer has crashed.  At the VT ground station (with KJ4QLP
operating) we have seen MBL (microbootloader) control interaction
between the spacecraft and the ground (MBLCTL packets).   This means
the command station(s) are interacting with a crashed spacecraft
computer.

I do not have ANY inside information.  I am reporting only on what I
can see with my own packet decoder....
