Workers prepare the surface of one of the three lightning protection system towers for painting at Exploration Ground Systems’ Launch Complex 39B at NASA’s Kennedy Space Center in Florida on May 30, 2019. The old paint was removed by the most recent hurricane. Pad 39B is the site of future launches of the agency’s Space Launch System rocket with the Orion spacecraft on Artemis missions. The 600-foot-tall lightning towers will help prevent lightning strikes at the pad during prelaunch and launch activities.
