Located 23 miles south of Houston, NASA/Johnson Space Center (named for Lyndon B. Johnson) is the training facility for all of America’s astronauts. 

Houston was the first word spoken on the moon when, on July 20, 1969, Neil Armstrong said, "Houston, Tranquility Base here. The Eagle has landed."

Johnson Space Center is also the control point for U.S. human space flight activities, with primary responsibilities in research, design, development, testing and operations of the Space Shuttle and Space Station programs. 

While NASA maintains 11 major U.S. installations, including its Washington, D.C., headquarters, Johnson Space Center (JSC) in Houston is the largest. 

Since the 1964 opening of JSC, its scientists, engineers and craftspeople have managed design, development and testing of all U.S. human spacecraft.

Johnson Space Center employs approximately 17,000 engineers, scientists and administrative personnel.

Mission Control Houston teams have been vital to every U.S. human space flight since 1965, including the Apollo mission and more than 100 Space Shuttle flights.

The Center’s rigorous astronaut selection and training program uses highly specialized facilities and equipment to prepare crews for missions.

The JSC Office of Technology Transfer and Commercialization offers opportunities for companies to access and utilize emerging technologies for non-space applications.

Space Center Houston is the designated visitor center for JSC and features interactive exhibits to educate and entertain visitors as well as showcase America’s accomplishments in space.
