NASA Chief Defends going to the Moon

Mike Griffin defended NASA's plan to return to the Moon instead of going straight to Mars. A group of scientists and engineers recently questioned the need to return to the Moon.

Griffin said, "I'm always intrigued by the idea that since we've spent a few days on the moon that the place is now uninteresting for all future time and that we should ignore it and head straight for Mars,"

Here is a roundup of some of the criticism.
