*UPDATE: January 8, 2010, 1712 UTC, 12:12 PM: *

*Troubleshooting is continuing, but we saw a similar problem a few years ago, 
and have a documented fix to return to nominal operations. In addition, the 
personnel that executed it last time are still available.  It is a long 
procedure, so will be executed as the current pass schedule allows.
