Space History
NASA's Johnson Space Center Is in Harris County
NASA selected a site near Clear Lake in southeastern Harris County for what became the Johnson Space Center in 1961, shaping the Clear Lake area.
In 1961, NASA chose a site near Clear Lake — in what is now Harris County's southeast corner — as the home of its new Manned Spacecraft Center. It was renamed the Lyndon B. Johnson Space Center in 1973. Houston became known as 'Space City.'
The Space Center is at 2101 NASA Pkwy in Houston. The public visitor center, Space Center Houston, is operated by a nonprofit at the same location. The center has been the home base for astronaut training and mission control for decades, including the Apollo missions, Space Shuttle program, and International Space Station operations.
