What is up with the lunar robotic program?

Check out this great explanation of the state of the lunar robotic program from InterplanetSarah. I couldn't agree more - if Congress wants NASA to explore the Moon, Congress needs to give NASA the money to do so, and then let NASA do it. LRO will go in 2009 and human landings are scheduled for 2018 - what will we be doing at the moon in the interim? It's the perfect opportunity to show we can land on another planet robotically and retrieve samples, and learn more about the environment we're sending humans into to boot.
