Before I left town for the NASA Tweetup a co-worker asked me "How does the Space Program benefit the average person." Initially all I could think of was Velcro. I remembered from a previous visit to Kennedy Space Center that they had a hand in making its use widespread. According to Wikipedia, "...Velcro only became widely used after NASA's adoption of it, NASA is popularly — and improperly — credited with its invention." While Velcro is a great product, I think most of us could agree that in any given day we could probably live without it. If I had enough time while I was in Florida last week I would have taken detailed notes at the exhibit answering this question at the Kennedy Space Center Visitors Complex. Since I didn't I was hoping to find a better list of more substantial items online. It took a bit a of searching but I think I found that list.
