That depends, if NASA is going to over-inflate the costs, waste time on outdated technology, not try anything new or cutting edge, and only take samples that are inconclusive, then no, they sure as hell should not send Astronauts back to the moon. Use the money to fund private companies that have the balls to try things. NASA shot themselves in the foot when they cut themselves off to using anything nuclear back in the late 1950s and 1960s, space is full of radiation, get used to it.
NASA is full of a bunch of egg-heads that should not be running a space program? Why? Because space travel is one of the most dangerous and technologically demanding pursuits man can engage in. A bunch of bureaucrats running a space-program isn't really a space program at all. We should have made many more advances than we have in the last 50 years. Space technology has fallen behind, to the point of being pathetic. Computer and power technology has advanced by leaps and bounds in the last 50 years, yet NASA plans to spend more money on basically the same equipment that we used 40 years ago? That would be like the army mass producing Sherman Tanks from WW2 again, or the Air Force using Bi-planes.
