The Space Shuttle Simulator is a limited time premium decoration that was released during the Deep Space Homer 2016 Event. If the player already had Barney unlocked, then this came bundled with Astronaut Barney for 120 Donuts, otherwise it was sold separately as for 75 Donuts. During the event, it generated event currency, NARA Certification Stars. It returned during The Marge-ian Chronicles Promotional.
