Exploring Houston - NASA
"Houston" was the first word spoken from the moon.
The Johnson Space Center (JSC) is located in the Clear Lake area, about 25 miles south/southeast of downtown Houston, via Interstate 45 South, NASA Road 1 exit.
From the early Gemini, Apollo and Skylab projects to today's International Space Station and Space Shuttle Programs, JSC continues to lead NASA's efforts in human space exploration. JSC nurtures ties with leaders in business, community and education, both locally and around the world, to make available the knowledge and advances achieved through space exploration research.
Space Center Houston, NASA's Official Visitors Center features actual spacecraft, like the Mercury, Gemini and Apollo capsules, and a walk in space through state-of-the-art simulators. Visitors also see behind-the-scenes tours of the famed Johnson Space Center and a huge display of space flight hardware and astronaut memorabilia.
