Construction crews lay wooden mats on top of sand and reinforcing steel to protect the concrete during deconstruction.

At NASA's Kennedy Space Center in Florida, construction crews lay large wooden mats on top of sand and reinforcing steel to protect the concrete under the rotating service structure (RSS) of Launch Pad 39B during deconstruction.

Starting in 2009, the structure at Pad B was no longer needed for NASA's Space Shuttle Program, so it is being restructured for future use. The new design will feature a "clean pad" for rockets to come with their own launcher, making it more versatile for a number of vehicles. For information on NASA's future plans, visit www.nasa.gov.
