Kennedy Space Center Director Bob Cabana, left, and Therrin Protze, chief operating officer of Kennedy's Visitor Complex, celebrate the dedication of the spaceport's historic countdown clock as the newest display at the center's visitor complex. Now located at the entrance to the visitor complex, the spaceport's historic countdown clock was used starting with the launch of Apollo 12 on Nov. 14, 1969. Originally set up at the space center's Press Site, the clock operated through the final space shuttle mission, STS-135, launched on July 8, 2011. The old countdown clock was replaced in 2014 with a modern light emitting diode, or LED, display.
