This leader in space education has recently added the 160-seat Sudekum Planetarium and the 13,000-square-foot Sky and Space Wing. The latter features the Solar System Survey, where visitors may follow the Planet Walk by tracing orbits embedded in the floor and interact with Worlds of Wonder, a sphere displaying color images of our solar system. The new wing also features Testbed, where visitors may experiment with space exploration tools in a spectacular two-story-high astronaut training and technology center.
