With the mission "to ignite and sustain lifelong science and technology learning", the Saint Louis Science Center is one of the top five science centers in the United States, and has been named one of the Top 10 Science Centers for Families by Parents Magazine and one of America's most visited museums by Forbes Traveler Magazine. The complex includes over 96,000 sq-ft of interactive science-technology exhibits that are part of the Science Center's free general admission. The most recent major permanent exhibit is GROW, a one-acre outdoor exhibit that will take visitors on a journey of food, to gain a deeper understanding of our food supply. The Science Center's ticketed areas include the OMNIMAX, a four-story IMAX Dome theater; the James S. McDonnell Planetarium, one of the world's largest planetariums; and the Discovery Room, an activity area for families with younger children.
