Just as for the first 24 shuttle flights, LC-39A supported the final shuttle flights, starting with STS-117 in June 2007 and ending with the retirement of the Shuttle fleet in July 2011. The damage had been exacerbated by the fact that hydrochloric acid is an exhaust by-product of the solid rocket boosters. The subsequent investigation found that the damage was the result of carbonation of epoxy and corrosion of steel anchors that held the refractory bricks in the trench in place. Since then, Pad 39A hosted all Space Shuttle launches until January 1986, when Space Shuttle Challenger would become the first to launch from pad 39B during the ill-fated STS-51-L mission.ĭuring the launch of Discovery on STS-124 on May 31, 2008, the pad at LC-39A suffered extensive damage, in particular to the concrete trench used to deflect the SRBs' flames. The first usage of Pad 39A for the Space Shuttle came in 1979, when Enterprise was used to check the facilities prior to the first operational launch. With the advent of the Space Shuttle program in the early 1980s, the original structure of the launch pads were remodeled for the needs of the Space Shuttle. The subsequent Skylab crewed missions launched from Launch Complex 39B using Saturn IB launch vehicles. This utilised a modified Saturn V originally built for the cancelled Apollo 18 mission. Launch Complex 39A was used for the uncrewed launch of the Skylab space station on May 14, 1973. With the exception of Apollo 10, which used Pad 39B (due to the "all-up" testing resulting in a 2-month turnaround period), all crewed Apollo-Saturn V launches, commencing with Apollo 8, used Pad 39A. The second uncrewed launch, Apollo 6, also used Pad 39A. The first launch from Launch Complex 39A occurred in 1967 with the first Saturn V launch, which carried the uncrewed Apollo 4 spacecraft. įirst named Launch Complex 39C, Launch Complex 39A was designed to handle launches of the Saturn V rocket, the largest and most powerful launch vehicle, which would propel the Apollo spacecraft to the Moon. Congressional approval led to the launch of the Apollo program, which required a massive expansion of NASA operations, including an expansion of launch operations from the Cape to adjacent Merritt Island to the north and west. In 1961, President Kennedy proposed to Congress the goal of landing a man on the Moon by the end of the decade. Typically used to launch NASA's crewed spaceflight missions since the late 1960s, the pad was leased by SpaceX and has been modified to support their launch vehicles. The pad, along with Launch Complex 39B, was first designed to accommodate the Saturn V launch vehicle. Launch Complex 39A ( LC-39A) is the first of Launch Complex 39's three launch pads, located at NASA's Kennedy Space Center in Merritt Island, Florida.
