In a previous space project we used SH2A because it was used successfully by colleagues previously, and had undergone the requisite radiation screening already.

It was obsoleted but we could get enough stock for the project. What we didn’t realize at the start was that the previous project had lower standards for development and testing and didn’t have the special debugger or great code. The debugger had to be special ordered for a ton of money and no vendors wanted to work on it.

Had a chance to revision up and changed to a pretty obscure atmega micro that was a perfect replacement. Did radiation screening again, development and testing..

That part was obsoleted too and I can’t use it for my next project. Will probably buy a space grade cpu for $20k this time. Radiation screening alone for a few components is $50k.

I worked on some data acquisition software that was in a beam-line (SLAC), but we just made sure to surround everything with lead bricks.

I've never sent any hardware into space, but some former colleagues of mine were working on OWL around the time I left: https://asd.gsfc.nasa.gov/archive/owl/science.html
