Eli5: “Why do spacecraft keep exploding, when we figured out to make them work ages ago?”

Question

I know its literally rocket science and a lot of very complex systems need to work together, but shouldnt we be able to iterate on a working formular?

Answer 1

We do iterate and we get better.

There is far less lethal accidents in space compared to 20 years ago.
