You may or may not have been waiting eagerly for it, but NASA’s official iPhone app is here, and it’s free of charge (yay). Created by the New Media Team over at NASA Ames Research Center, it does feature quite a few interesting features. The front of the app updates you on current and future NASA missions, and the bottom offers your buttons for missions, images, videos and updates, so you’ll always be in touch with NASA’s activities. Happy? We certainly are.
