Officials at the Cosmosphere announced a five-year, $15 million plan Tuesday, with a goal of securing the institution’s future for the next 50 years.

The Hutchinson News reports the master plan includes significant changes to the Cosmosphere’s mission and exhibits without expanding beyond the existing building.

Currently, only about 8 percent of the Cosmosphere’s 13,000 exhibits are on display. Cosmosphere President and Chief Operating Officer Jim Remar says the new plan includes more room for displays in existing space, adding exhibits in the lobby and possibly more displays in a new food-service area.

The plan also includes a major emphasis on informal STEM (science, technology, engineering and mathematics) education initiatives, including two STEM labs.
