My favorite Bill quote: "People in other countries aren't wearing Department of Agriculture shirts."

He explained that NASA is one of America's best brands. That funding NASA is critical to maintaining both US leadership in space and the image of America as a superpower in science and exploration.

NASA science represents something unique and special to Americans and to people around the world because NASA pushes the bounds of what is knowable. The threat of impoundment on NASA funds is reckless and ignorant of what NASA does and what it takes to successfully explore (more successful than any other space agency in history at least) farther than any human in existence.

To defund NASA now would be an unneeded and useless tragedy for the human race.

On today's occasion I remembered this sites that is one of the more interesting things on the internet, where you can relive the moon landing 'in real time'.

Hope you all enjoy it.
