Quantifying the price for redundancy
It’s amazing how long these nasa space systems have survived past their expected life.
Building these things with durability in mind has undoubtedly saved billions in additional launches and spacecraft.
That said the observations returned have undoubtedly spawned additional missions.
Many NASA missions have lived long past their expected duty cycles.
I wonder if future missions will have the same Durability especially as we all know that costs extra.
Well done NASA for having the temerity to succeed.
