I have been very impressed with the Cassini mission reporting, both with the quick release of raw data, new observations, and the event log:

http://saturn.jpl.nasa.gov/news/sig-events.cfm

It is great to have a front row seat to a great mission!

I bring attention to this here, because of this entry in the Cassini event log:

QUOTE
It turns out that the SSPS for the USO was tripped, causing no one-way
downlink carrier or data. This tripped switch condition is consistent with
ones seen in the past. This is the sixteenth trip seen to date, the third
trip of a switch that was ON at the time, and the second trip this year. The
previous trip occurred very recently on March 2, 2006. They are predicted
to occur at a rate of about two per year, and are most likely caused by
Galactic Cosmic Rays.


I have to ask the question: Could the Huygens channel 'A' failure have been caused by the accidental tripping of the SSPS for the Huygens USO by a cosmic ray, rather than a programming error? The announcement that it was a programming error was made on the same day as the landing, at a time when everyone was exhaustively tired and not necessarily in best form for analysing code.

Has a follow-up report been issued confirming the programming error? Was it related to ITAR access restrictions as has been intimated elsewhere? As a sometimes analyst of critical event programing, it is difficult for me to imaging that the command to "Turn on the Power Supply" was omitted from a programing sequence that developed through years of careful planning. This is one time that a gremlin makes more sense.
