NASA's Most Historic Launchpad
Launchpad 39A at NASA's Kennedy Space Center in Florida sent the first astronauts to the moon, supported dozens of space shuttle missions, and now serves as a commercial launch site.
Pictured here: An aerial view of Launch Pad 39A taken during the Apollo era in 1976.
Construction of the launch complex began in 1963. Pictured here is the early construction phase of Pad 39A in July 1964.
A Flame Trench is Born
By September 1964, the hardstand on both sides of the flame trench beneath Pad 39A begins to take shape.
Concrete in Place
By November 1964, most of the concrete has been poured at Pad 39A.
Construction of Pad 39A was nearly complete by January 1965.
Launch Complex 39's warning system lights, pictured here on May 25, 1966, included a light for Pad C, which was originally planned but never built.

The U.S. launched its first space station, Skylab, from Pad 39A on May 14, 1973.
Giant Erector Set
Construction of the payload changeout room for the Space Shuttle Program made it possible to install payloads while the space shuttle stands vertically on Pad 39A.
