The data is sent from these computers to the matrix switch, which distributes video information to the screens on the GNOC floor and to other parts of the building. The heat buildup is incredible, and lamp life is shortened. HOK designed easy access to the projectors, which require relamping two or three times a year. With so much electronic equipment running at full capacity in one space, heating loads are tremendous. Throughout the building, the power supply is primarily run beneath a typical steel raised floor.
Cables pass through roomy ceiling trays, which allow for future expansion.
With so much electronic equipment running at full capacity in one space, heating loads are tremendous. Having the GNOC underground mitigates some of the demand, but cooling still requires two 375-ton chillers. A third was installed for future use. Backup generators ensure a redundant fail-safe operation. Built in 1963 and located in Building 30 at the Johnson Space Center, Mission Control was technologically sophisticated in its day.
