Could you, though? It's not that they write trivial code just because they have clear specs.

And a simple mistake can make you explode while in space.

Sure, we might have to deal with unclear specs and changing requirements, but even given that most of what we do is 1/1000 to 1/10 the complexity of what NASA programmers do.
