(which was originally to be the prime factory for station launch processing) was insufficient in size to accommodate all the components. On March 26, 1991, engineers at Kennedy Space Center; along with contractor Metric Constructions Inc. of Tampa Florida, broke ground on a new $56 million Space Station Processing Facility, situated adjacent to the O&C. The design called for a 457,000-square-foot multifunction building housing an enormous processing bay, laboratories, control rooms, staging areas, communications and control facilities, and office space for some 1,400 NASA and contractor employees. KSC Deputy Director Gene Thomas described the construction: "The skyline around here is really going to change. This will be the biggest facility that we have built since the Apollo days". The SSPF used reinforced concrete and some 4,300 tons of steel. The building was structurally completed and topped out by mid 1992. After three years of construction, interior fitting and equipment set-up, the SSPF formally opened on June 23, 1994.


Operations and manufacturing processes

At the SSPF, space station modules, trusses and solar arrays are prepped and made ready for launch. The low and high bays are fully air conditioned and ambient temperature is maintained at at all times. Workers and engineers wear full non-contaminant clothing while working. Modules receive cleaning and polishing, and some areas are temporarily disassembled for the installation of cables, electrical systems and plumbing. In another area, shipments of spare materials are available for installation.

frames are assembled and welded together, allowing the installation of instruments, machines and allowing science experiment boxes to be fitted. Once racks are fully assembled, they are hoisted by a special manually operated robotic crane and carefully maneuvered into place inside the space station modules. Each rack weighs from 700 to 1,100 kg, and connect inside the module on special mounts with screws and latches. Cargo bags for MPLM modules are filled with their cargo such as food packages, science experiments and other miscellaneous items on-site in the SSPF, and loaded into the module by the same robotic crane and strapped in securely. Many of the builders accompanied their modules from around the world during their manufacturing, and worked at KSC for months to years during final assembly. Many ISS modules were renamed after successfully launching.


Station Integration Testing

Regarding the launch of modules of the

(ISS), there had been philosophical differences for years between designers and payload processors whether to ship-and-shoot or perform integration testing prior to launch. The former involved building a station module and launching it without ever physically testing it with other modules. The integration testing was not originally in the ISS plan, but in 1995

designers began to consider it and embedding KSC personnel at module factories. Multi-Element Integration Testing (MEIT) of ISS modules at KSC was officially in the books in 1997.

Numerous issues were found and rectified from these on the ground tests, many of which could not have been fixed in orbit.
