On Launch Pad 39B at NASA’s Kennedy Space Center in Florida, the giant crane moves equipment that will be used to continue erecting the lightning towers. Each of the three new lightning towers will be 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 compared to the space shuttle. Pad B will be the site of the first Ares vehicle launch, including Ares I-X which is targeted for summer of 2009, as part of NASA’s Constellation Program. Photo credit: NASA/Kim Shiflett
