A giant crane lifts the lightning mast alongside the tower one of three around the pad.

On Launch Pad 39B at NASA's Kennedy Space Center in Florida, a giant crane lifts the 100-foot lightning mast alongside the newly erected lightning tower, one of three around the pad. The mast will be installed on top of the tower. 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
