NASA has released their first official iPhone game called the NASA Lunar Electric Rover Simulator.
Welcome to the NASA Lunar Electric Rover (LER) Simulator. You don’t need a driver’s license, but you still need to buckle up as the LER Simulator gives you a glimpse of what it might be like to support the activities of a functioning Lunar Outpost. Get busy. You never know if your skills here will become a major part of the NASA Astronaut application process in the future.
You can download NASA Lunar Electric Rover Simulator from the App Store for free.
