NASA has released a web and mobile game app that explains how space communications work.
"NetworKing" enables the player to build increasingly complex network communications that coordinate client satellites conducting scientific missions.
The goal for the player is to build a system similar to NASA's Deep Space Network to support spacecraft missions, upgrade the infrastructure to increase its capacity and support more complex clients, including the International Space Station and NASA's Hubble and Kepler space telescopes.
There are also several unlockable missions that visualize how the networks work.
NASA is offering NetworKing as app downloads for the iPhone and iPad from the Apple App Store as well as a browser-based game for Mac and PC. To run the game in a browser windows, players need to install the Unity browser engine.
