There is a lot in this app to play with. If you have kids, they may not even know who Buzz Aldrin is outside of a multiple choice answer on a second grade history test. But us parents know who he is, and we love our heroes as much as the kids love theirs! This really is a good educational tool, and may even put a little spark of interest in space with the kids. Hey, space is cool! As a 40 year old kid, I have to say that there is a certain nostalgia involved for me when I use this app, but I also enjoy using it very much because it is thoughtfully planned and nicely done. Love the feed from NASA, love the pictures, love reading about the shuttle missions. Buzz Aldrin should be quite proud of this application. This app makes me want to go buy a telescope.
