People mock Musk's process of "test it until it breaks," but it has produced incredible results for commercial rocketry while causing costs to plummet. NASA tends to get a pass despite these 1-in-6 failures or the Challenger and Columbia disasters.
NASA has done better since Columbia but that isn't saying much since they haven't been doing nearly as much since the retirement of the shuttle program. They have the SLS with one successful launch. It's so expensive though. Meanwhile, Starship has managed at least four successful test flights with the next scheduled in January. They already have a couple of commercial payloads scheduled starting in 2027. Their ultimate goal is to be able to launch multiple Starships a day which seems entirely doable, probably within a few years, given the success of the Falcon 9. I can't wait until they start launching Starships in Florida.
