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?

We’re still making improvements to car engines, even though they’ve been around for centuries and commercially available for over a hundred years.

Even with all the money going into making over 1 billion cars, we still haven’t perfected the car engine.

Rocket engines, on the other hand, are devices that are
* made in much smaller numbers
* cost much more individually
* have much higher engineering challenges in terms of temperature and working conditions
* have far fewer people who have expertise in them

Consider that every time a rocket engine designer dies / retires a much larger percentage of the overall expertise is lost than when a car engine designer does.

As such rocket engines are far more temperamental than most engineered devices on earth, and will likely continue to be for the foreseeable future.
