That is an interesting idea and something I was wondering about, although I don't think that SO41 had a long lifespan, so it might have been built to different standards.

Maybe they put a little more research and money into the development and construction, I think that was reflected in a different quality in their circuits, which has caused their life to be prolonged.

SO-50 will be 22 years old in December and seems to be still be going strong, in sunlight and in eclipse.  No other satellite launched since then has lived near that long.  So what is SO-50s key to long life?  Is it how the satellite was built?  Something in its operation, like lower power on transmit?  Its orbital setup?

Any ideas why it has lived so much longer than the recent crop of AMSATS?
