Fail often, fail hard, learn.
SpaceX launched a fullstack Starship/Super Heavy this morning, and it exploded 3:59 into the flight. This was a resounding success.
“Why? Because one could sit in meetings for ages and discuss everything that could go wrong with a rocket like this, with an unprecedented number of first stage engines and its colossal size. The alternative is simply to get the rocket into a “good enough” configuration and go fly. Flying is the ultimate test, providing the best data. There is no more worrying about theoretical failures. The company’s engineers actually get to identify what is wrong and then go and fix it. But you have to accept some failure.” (Eric Berger, link below)
So congratulations to SpaceX on a successful failure of a launch!
