@ceo.tesla.elon6: Starship was first planned in carbon fiber. SpaceX switched to stainless steel around 2018-2019, and steel also gets stronger at the super-cold temperatures of rocket fuel. SpaceX passed on carbon fiber and aluminum-lithium for Starship and went with stainless steel. It’s easy to weld, much cheaper, and in the right conditions it holds up about as well as carbon fiber for its weight. A cheap material you can build tons of beats a fancy one you can barely afford to build once. #usa #elonmusk #viral #fyp #tiktok
