The existence of Apollo is a curse that has made it almost impossible for NASA to plan any modest sustainable capabilities in human exploration. Instead it's often "let's build our own huge rockets and launch a few huge missions per year". This makes it expensive and unsustainable.

Concentrate on what your core competencies are. Start small and verify your solutions.
