KENNEDY SPACE CENTER, FLA. -- The 209-foot-tall mobile service tower on Pad 39-A of Space Launch Complex 36 on Cape Canaveral Air Force Station careens to the left after 122 pounds of explosives eliminated the base. The tower is one of two that were identified for demolition. The old towers are being toppled as part of the ongoing project to demolish the historic site to prevent corrosion from becoming a safety concern. A majority of the steel will be recycled and the rest will be taken to the landfill at CCAFS. Complex 36 was the birthplace of NASA's planetary launch program. It was built for the Atlas/Centaur development program and was operated under NASA's sponsorship until the late 1980s. Complex 36 hosted many historic missions over the years including Surveyor that landed on the moon and Mariner that orbited Mars and included one to Mercury. Two of the most historic launches were the Pioneer 10 and 11 space probes that were launched to Jupiter and are now outside of the solar system in interstellar space. Also, the historic Pioneer Venus spacecraft included an orbiter and a set of probes that were dispatched to the surface. While Launch Complex 36 is gone, the Atlas/Centaur rocket continues to be launched as the Atlas V from Complex 41. Photo credit: NASA/Charisse Nahser
