I also take issue with the -60C minimum power-down temperature. I think this is unrealistic just from a CTE mismatch perspective. The reliability of anything subjected to that wide a temperature spread is going to suffer. A way must be found to raise that temperature.
As I understand this the low temp came from the combination of the need to heat sink the receiver and the long eclipses. If, during the redesign, John could find a way to avoid needing the heat sink then the temp swings would be much less.
