Minecraft in Space: NASA embraces the space simulator Kerbal Space Program with the Asteroid Redirect Mission patch.
Hullloooo, this is Scott Manely! He likes making tutorial videos of Kerbal Space Program, a space flight simulator game. After more than a few design suggestions from his father, who's an engineer, Scott decided to let him 'show me how it's done' and design a spaceplane.
Kerbal Space Program is a cartoon-ish game in which you build rockets from pieces and launch/fly them around in a simulated solar system using basic orbital mechanics. It has an active forum, extensive modifications, a whole site dedicated to plugins and mods, and its own subreddit. This youtube video demonstrates the latest version, 0.18. [more inside]
