On occasion, when one is asked to describe a common activity or simple concept, the other party may exclaim, “Well, it’s not exactly rocket science.” Well, this website is exactly that: rocket science. To be more precise, NASA has created this elegant and visually stimulating demonstration website that allows guests the opportunity to learn how two different types of rockets (the Delta II and the Atlas V) are constructed. First-time visitors will most likely want to take advantage of the short tutorial that explains the basic part of the launch vehicle, how it is constructed, and how all of these parts effectively help launch a NASA spacecraft. After looking over this section, visitors will want to get started on constructing their own rocket. They will have the opportunity to learn about different parts of each device, and then select each item for the rocket. At the conclusion, visitors will get to see a demonstration of how each rocket works during flight.
