All summer, Houston Matters is visiting Houston area museums and attractions we think you might be interested in checking out in person. Today, we take you to Space Center Houston in Clear Lake.   The 250,000-square-foot complex houses over 400 artifacts and exhibits celebrating the U.S. space program. It is also the public gateway to the Johnson Space Center, which is home to an astronaut training facility, a park housing the Saturn V rocket, and the historic Mission Control Center that sent the first astronauts to the moon. Listen to Houston Matters producer Laura Walker as she takes us on an audio tour at HoustonMatters.org #spacecenterhouston #nasa #spacehouston
