Constelation

In the rosy light of dawn, construction continues on the new lightning protection system for the Constellation Program on Launch Pad 39B at NASA's Kennedy Space Center in Florida. Each of the three new lightning towers will be 500 feet tall with an additional 100-foot fiberglass mast atop. 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.
