This certainly sounds like a spot of good news. My fingers are
crossed. :)

I am curious about one thing: the contingency plans for the 40 bps  
data speed vs the 110,000 (?) bps included a lossy compression
scheme related to JPEG that would allow compression of between 10
to 100 times. If the HGA is freed, allowing the high speed
transmission, will the compression still be used (hopefully with
'a higher Q value') so that even _more_ data than anticipated in
the original mission plan be returned?
