What Is Open Now: Phase 1
The museum's space science exhibit page lists two missions in Phase 1, which opened October 10:
- Mission 01: Lunar Lander. A pilot's-seat simulator with interactive controls and sound effects. The museum's photo shows a lander-style structure labeled "Event Horizon," with an open doorway leading to a control console, set against a moon-surface and star-field backdrop.
- Mission 02: Mission Control. A teamwork activity that focuses on communication and problem-solving.
The St. George Area Chamber of Commerce listed a grand opening and ribbon cutting for the newly updated Space Science Room on Saturday, October 10, from 11 a.m. to 1 p.m., with space-themed crafts and activities for the whole family.

Why a Space Exhibit Fits Southern Utah
Southern Utah's dark skies and open terrain have long made stargazing a regional pastime, and the area has recently leaned into aerospace as well. Utah Tech University hosted retired NASA astronaut Steve Swanson for a free community talk on October 26; our coverage is in Liftoff: Red Rock to Red Planet. A hands-on lunar lander gives younger children a way into the same subject, and the mission-control activity is built for groups working together.
The museum is in downtown St. George, so it pairs easily with other downtown stops. Our guide to things to do in St. George with kids and our November 2026 things-to-do guide list more options, and the museum's full profile is on its business listing.
