Visiting during spring break? Buy your tickets here.

We’re inviting a few close friends over. Can we show you around?

As a member, you’ve seen a lot of MSI, but never as much you’ll see on our biggest night of the year! It’s a spectacular look behind the scenes, with one-night-only experiences and activities, tours of employee-only spaces, rarely seen treasures from our vast collection of artifacts and a whole lot more. 

Add in free flight simulator and VR Spacewalk rides, snacks, drinks, and cap it off with an ice cream cone. It’s a night like no other, and it’s only for our valued members to enjoy.
