Due to funding issues beyond NASA's control
Nasa spent 40 years and $500 billion on US manned spaceflight since Apollo ended... without getting a single American beyond low earth orbit, and leaving itself incompetent/incapable of crewing or even resupplying our own space station...
Nasa's shuttle cost a shameful $1.6 billion/flight.. the ISS went from $8 billion to $200 billion.. Constellation was a $20 billion boondoggle..
Nasa=another bloated, wasteful, pork driven Federal Agency
