This facility, located in Houston, Texas, was responsible for crew safety and mission success for early manned space programs, including Apollo 11 and Ares IV.
The first MCC patch was designed by Robert McCall, who, as well, was responsible for the Apollo 17 patch. This patch honored the Mercury, Gemini, and Apollo programs with their symbols.  There were two of these patches on display in the club.
