Your guide to the night sky!

The Saint Louis Science Center's James S. McDonnell Planetarium is one of the nation's leading space education facilities.

  • Key Features
  • Juno Education Materials

It features the unique Boeing Space Station, with two fabulous levels of exhibits that incorporate scientific research, illustrating the future of space travel. The Orthwein StarBay has several lab areas, including the SBC Learning Center, that gives you a glimpse of what it's like to live and work on the International Space Station. In the Crew Quarters see how dwellers eat, exercise, sleep and dress in space, as well as how medical needs and the station's internal and external environments are maintained.

Zeiss Projector

The StarBay's most amazing feature is the central open area dominated by the Zeiss Planetarium Model IX which projects more than 9,000 stars onto an 80-foot dome creating a brilliant star field. Visitors can look up and see what the actual night sky would look like without the interference of weather, pollution or city lights. Special features allow Planetarium staff to demonstrate eclipses, meteor showers and other celestial phenomena. The immensity and clarity of the view creates a sense of wonder and stimulates the imagination.

The StarBridge, located on the highest level, focuses on the navigation and operations essential for life in space. Exhibits demonstrate the roles that communication, astronomical research, power and exploration will play in maintaining a space station.

The Planetarium’s lobby features two real spacecraft which were built right here in St. Louis!  A Mercury capsule and a Gemini Capsule.  Also on display is a real meteorite you can touch!
