Expendable launch vehicles (ELVs)

Beginning in 1958, NASA and military worked side by side on robotic mission launches (previously referred to as unmanned), cooperating as they broke ground in the field. In the early 1960s, NASA had as many as two robotic mission launches a month. The frequent number of flights allowed for quick evolution of the vehicles, as engineers gathered data, learned from anomalies and implemented upgrades. In 1963, with the intent of KSC ELV work focusing on the ground support equipment and facilities, a separate Atlas/Centaur organization was formed under NASA's Lewis Center (now Glenn Research Center (GRC)), taking that responsibility from the Launch Operations Center (aka KSC).

Though almost all robotics missions launched from the Cape Canaveral Space Force Station (CCSFS), KSC "oversaw the final assembly and testing of rockets as they arrived at the Cape." In 1965, KSC's Unmanned Launch Operations directorate became responsible for all NASA uncrewed launch operations, including those at Vandenberg Space Force Base. From the 1950s to 1978, KSC chose the rocket and payload processing facilities for all robotic missions launching in the U.S., overseeing their near launch processing and checkout. In addition to government missions, KSC performed this service for commercial and foreign missions also, though non-U.S. government entities provided reimbursement. NASA also funded Cape Canaveral Space Force Station launch pad maintenance and launch vehicle improvements.

All this changed with the Commercial Space Launch Act of 1984, after which NASA only coordinated its own and National Oceanic and Atmospheric Administration (NOAA) ELV launches. Companies were able to "operate their own launch vehicles" and utilize NASA's launch facilities. Payload processing handled by private firms also started to occur outside of KSC. Reagan's 1988 space policy furthered the movement of this work from KSC to commercial companies. That same year, launch complexes on Cape Canaveral Air Force Force Station started transferring from NASA to Air Force Space Command management.

In the 1990s, though KSC was not performing the hands-on ELV work, engineers still maintained an understanding of ELVs and had contracts allowing them insight into the vehicles so they could provide knowledgeable oversight. KSC also worked on ELV research and analysis and the contractors were able to utilize KSC personnel as a resource for technical issues. KSC, with the payload and launch vehicle industries, developed advances in automation of the ELV launch and ground operations to enable competitiveness of U.S. rockets against the global market.

In 1998, the Launch Services Program (LSP) formed at KSC, pulling together programs (and personnel) that already existed at KSC, GRC, Goddard Space Flight Center, and more to manage the launch of NASA and NOAA robotic missions. Cape Canaveral Space Force Station and VAFB are the primary launch sites for LSP missions, though other sites are occasionally used. LSP payloads such as the Mars Science Laboratory have been processed at KSC before being transferred to a launch pad on Cape Canaveral Space Force Station.
