Rocket Brain allows you to view the insignias of some of the old U.S. manned space missions. You can also play a memory game with the insignias by collecting them and scoring points. Select each image only once for the maximum points. Each Group contains a fixed number of images. Once you have selected the last image in the group, the game is over. You can get bonus points if you select quickly. You will lose points if you select an image you have already selected. The optional tracker allows you to see what you have already selected, though the images are very small.
Use the Select view to choose which group (currently only Apollo, Gemini, Mercury, and some STS) to use for the game, and view some information about each program. The items in the top score list can be expanded to show more detail about the score. The maximum point total is 3 per image, so larger groups can get a higher score.
There is also a quiz about the members of each mission (except STS), and a trivia quiz to test your knowledge. All answered are based on the information contained in the App.
