On Launch Pad 39B at NASA's Kennedy Space Center places the lightning mast on top of the lightning tower.

On Launch Pad 39B at NASA's Kennedy Space Center in Florida, a giant crane (far left) places the 100-foot lightning mast on top of the newly erected lightning tower. Three new towers surround the pad. In the middle are the fixed and rotating service structures that serve the Space Shuttle Program. At far right is the tower that holds 300,000 gallons of water used for sound suppression during a shuttle launch. The new lightning protection system is being built for the Constellation Program and Ares/Orion launches. Each of the towers is 500 feet tall with an additional 100-foot fiberglass mast atop supporting a wire catenary system. This improved lightning protection system allows for the taller height of the Ares I rocket compared to the space shuttle. Pad 39B will be the site of the first Ares vehicle launch, including the Ares I-X test flight that is targeted for July 2009. Photo credit: NASA/Tim Jacobs
