There are probably only a very small number of people that know about this. Certainly the group of people I worked with at Motorola and the NASA engineers and techs associated with the program. Since NASA was able to come up with a fix to make everything work, I would guess it's probably not something they would want to publicize in general but I've always thought this was a very ingenious solution. The truth be known, there are probably stories like this on just about every mission they ever did. Stuff happens as they say. In the end, people can be very, very clever, especially when they have their backs against the wall. Problems like this are especially difficult as you can't just go hang a scope on something a million miles away. You have to first discover the problem and then, more difficult, given the only tools you have at hand and a spacecraft millions of miles away, come up with a solution that will solve your problem.
They (NASA) had done a few bone headed things too on programs I worked on but in general, they were right and bright more often than not. All of us screw the pooch some time or another but I look back on those days with a fond remembrance. I had radios I worked specifically on, on GRO, COBE, SME and the Hubble to mention a few. Interesting work and privileged to be a part of it.
