Space station processing

As the International Space Station modules design began in the early 1990s, KSC began to work with other NASA centers and international partners to prepare for processing before launch onboard the Space Shuttles. KSC utilized its hands-on experience processing the 22 Spacelab missions in the Operations and Checkout Building to gather expectations of ISS processing. These experiences were incorporated into the design of the Space Station Processing Facility (SSPF), which began construction in 1991. The Space Station Directorate formed in 1996. KSC personnel were embedded at station module factories for insight into their processes.

From 1997 to 2007, KSC planned and performed on the ground integration tests and checkouts of station modules: three Multi-Element Integration Testing (MEIT) sessions and the Integration Systems Test (IST). Numerous issues were found and corrected that would have been difficult to nearly impossible to do on-orbit.

Today KSC continues to process ISS payloads from across the world before launch along with developing its experiments for on orbit. The proposed Lunar Gateway would be manufactured and processed at the Space Station Processing Facility.
