NASA is no stranger to 3D. It has done some impressive CGI trips into galaxies and nebulae, and of course it has offered some stunning 3D images from the Mars spacecraft.
NASA has just released a free iPad and iPhone app called Spacecraft 3D. Here's how it works. You launch the app and then print out a target that you put on your desk or a table. The target allows the app to construct a spacecraft that you can see in three dimensions as your walk around it or change your elevation. Currently, the app features the Curiosity rover that will set down on Mars August 6, and the twin GRAIL spacecraft that are currently in orbit around the moon.
