NASA was (for decades) the most important institution when it comes to space exploration. But their take on getting stuff to space was to design and build single-use rockets to get to space. A famous quote from the movie Armagheddon comments on the way they went about this.
Enter Elon Musk: starting Spacex with the idea of changing rocket operation towards a process of rapid reuse, thus drastically lowering the cost of putting cargo into space! They also are considering purposing Starship for earthbound 'starhopping', turning twenty plus hour airplane flights into two hour hops.
