This Friday in this Blog's history I bring back to you the post on NASA's meaning.
What Does NASA Stand For?
Ask the average person what NASA stands for and he/she will almost always get it wrong. The 'N' is easy. National. Most people get the 'S'. Space. The 'As' are where people get messed up. It's very common for someone to say one of the 'As' stands for astronomy. Good guess, but nope.
So what does it stand for? I guess you'll have to check out the original post. :-)
