^So, are you saying we shouldn't explore space at all, or just that NASA is incompetent?
The problem with NASA is that they have had to play too much politics to get thier funds, so instead of just worrying about achieving goals, they also have to worry about spreading the money to as many states as possible when handing out contracts. This generates jobs in those states, making the people happy there and in turn making the senator/congress man representing them happy. Which all leads to making congress more favorable to providing more money. This does not lead to the most efficient spending habits.
