$500B for nada
Since the last Apollo launch America has spent $500B on NASA and we can't even get beyond LEO. Hell we can't even get TO LEO with any reasonable regularity.
Way to go Buck! I've made that very point for years but some space cadets are so enamored of all things NASA that they fail to realize that the org has completely pissed away an entire generation of spaceflight opportunity and budget. And yes, we're still stuck in LEO and we can't even get back there reliably. Look at the facts objectively, people. NASA deserves an F for manned spaceflight.
