Lunar Reconnaissance Orbiter Project Scientist Richard Vondrak

LRO is now circling the Moon, along with sister mission LCROSS and India's Chandrayaan 1. Richard Vondrak looks forward to the arrival of spectacular data and images that will help pick a landing spot for the return of humans. Bill Nye says NASA should go metric with the Constellation program. Bruce Betts and Mat Kaplan share some cheesy (but funny) analogies for the surface area of the Moon, leading up to yet another space trivia contest in What's Up!
