We're starting a new segment on SpaceVidcast that will be highlighting a different space agency each week. Since NASA is by far the largest agency of them all, we'll start here and show you where NASA came from, how much it spends, and how it looks on the surface in this brief 3 minute overview. NASA is so complex that we could spend hours talking about all the different areas, and we encourage you to continue the conversation in the comments section. Add your cool NASA stats or feelings there!
