Hmm, I seem to remember most of these cargo flights have had strange
guidance issues of one form or another close to the ISS, makes you wonder if
it might be some kind of interference or general crud comming from the
station which affects systems in unpredictable ways at times.

I'm guessing the problem with Cygnus is a classic software integration
problem. Most articles I read said that Cygnus was receiving data it
did not expect from ISS. I have not read anything about "interference"
in articles about the Cygnus software snafu.

NasaSpaceFlight.com gave a pretty comprehensive explanation of the
problem and the fix in an article with today's date.

Next attempt for ISS this Sunday...
