George Diller shovels the first scoop of soil behind the countdown clock during the groundbreaking ceremony for the new countdown clock.

At NASA's Kennedy Space Center in Florida, Public Affairs Officer George Diller shovels the first scoop of soil behind the current countdown clock during the groundbreaking ceremony for the new countdown clock. The old timepiece was designed by Kennedy engineers and built by Kennedy technicians in 1969. Not including the triangular concrete and aluminum base, the famous landmark is nearly 6 feet 70 inches high, 26 feet 315 inches wide and 3 feet deep. The new display will be similar in size, with the screen being nearly 26 feet wide by 7 feet high. For more information on the countdown clock, go to http://go.nasa.gov/10Zku10.
