NASA Administrator Michael Griffin in 2009
It is the law of the land to put a man on the moon before 2020.
In 2009 NASA Administrator Micheal Griffin said: "you would be amazed at the number of times I get questions from top level policymakers concerning, "why don't we just haul some of that Apollo equipment out of the barn and head back?"" The NASA Administrator would answer them with: "There is no barn. We will spend the next ten years recreating a lot of capability for space flight, hopefully going a little beyond, but we will spend the next ten years recreating capabilities that this nation once had and threw away, proactively and with mallows of forethought" (Video part 1 at 4:38). Earlier Griffin said that by the law of the land NASA is directed to land a man on the moon no later than 2020 (Video part 1 at 4:20 and 6:30). This monologue and Q&A is a little gem for those who have the ears to listen.
