ESC Empowers Part 2: It's Electric—Lightning Protection at Launch Complex 39B

CAPE CANAVERAL, Fla – In this second installment of our series detailing the efforts of the men and women of the Engineering Services Contract, or ESC, we will detail the efforts conducted to renovate and safeguard the historic Launch Complex-39B (LC-39B) for future use. Most importantly, what protects the launch complex’s expensive charges in the lightning capital of the world? 

Around the perimeter of LC-39B, numerous pods and weather gauges monitor and measure lightning strikes in the area. For protection purposes, three new 600-foot-tall lightning towers have been erected.

It was with this part of our tour that we began to gain a grasp on the diverse elements of the ESC contract. The realms of scientific research and engineering merged as we learned about efforts to refurbish the pad, which saw its first use in 1967, for 21st century purposes.

Launch Complex 39B has been renovated in the “clean” pad design, leaving very little to the eye. The one obvious exception to this is the three 600-foot-tall lightning towers that rise majestically into the Florida sky. Photo Credit: Alan Walters / awaltersphoto.com

The process to renovate LC-39B to serve as the platform for future missions was a painful one. As one part of a two-part structure (Launch Complex 39 is comprised of pads “A” and “B”), LC-39B ceased use temporarily in 2007. Large segments of the iconic structure were torn down and carted off, leaving a stripped-down and bare-looking, simplified “clean” pad designed to serve multiple launchers. Much of the systems needed to launch rockets are either internalized or are incorporated into the Mobile Launcher itself (more on what the ESC does on that will be in an upcoming feature).

AmericaSpace spoke with Tony Eckhoff and Carlos Matos during this portion of our tour, but the unpredictable Florida weather once again intervened. High winds obliterated the audio from Matos’ portion of the interview. Much of what Matos discussed was carried away in the winds, but, thankfully, the operators of the ESC, QinetiQ North America, have already agreed to allow us a “second take,” and we hope to bring the fascinating science used to predict and prevent lightning damage to you at a later date.

Stay tuned for the third installment in this series, where we delve deeper into the science that the ESC does at Kennedy Space Center when we learn about the science of payloads at NASA’s Space Life Sciences Lab.
